STL Files:STL (STereoLithography) is a file format native to the stereolithography CAD software created by 3D Systems. STL has several after-the-fact backronyms such as "Standard Triangle Language" and "Standard Tessellation Language". This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact. CAD: Computer-aided design (CAD) is the use of computer systems to aid in the creation, modification, analysis, or optimization of a design.CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. BEZIER SPLINES: It basically means a Beier curve.A Bézier curve is a parametric curve frequently used in computer graphics and related fields. Generalizations of Bézier curves to higher dimensions are called Bézier surfaces, of which the Bézier triangle is a special case. NURBS:Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces. It offers great flexibility and precision for handling both analytic (surfaces defined by common mathematical formulae) and modeled shapes. NURBS are commonly used in computer-aided design (CAD), manufacturing (CAM), and engineering (CAE) and are part of numerous industry wide standards, such as IGES, STEP, ACIS, and PHIGS. NURBS tools are also found in various 3D modelling and animation software package. ASCII:ASCII  Abbreviated from American Standard Code for Information Interchange, is acharacter-encoding scheme (the IANA prefers the name US-ASCII). ASCII codes represent text in computers,communications equipment, and other devices that use text. Most modern character-encoding schemes are based on ASCII, though they support many additional characters. ASCII was the most common character encoding on the World Wide Web until December 2007, when it was surpassed by UTF-8, which includes ASCII as a subset.

A 3D printed unmanned aircraft by a student in Spain

# data[].attributes.attachment_link.readable_text
We have recently been contacted by Jonatan Domènech Arboleda, a student from the School of Industrial and Aeronautic Engineering of Terrassa (part of the Universitat Politècnica de Catalunya, Spain). Jonatan has just completed a remarkable project, a 100% 3D printed Unmanned Aerial Vehicle (UAV) also known as the Barcelona UAV.

Keen to share his creation with other 3D printing enthusiasts, Jonatan reached out to us. Looking at the UAV project in more detail quickly made us realize that this project would be worth sharing with our audience. The UAV is not only a nice piece of engineering but also an excellent demonstration of what 3D printers are already capable of today. Jonatan did all his 3D prints on a RepRap using PLA filament. No fancy materials or industrial type 3D printers.

We hope that sharing this 3D printing project will open a few eyes when it comes to the capabilities of 3D printers and maybe inspire a few readers to start similar ambitious projects.

Here is what Jonatan has to say about his project:

1. What Led You to Develop the 3D Printed UAV?

The idea to develop the 3D printed UAV came originally from Jordi Santacana, the director of CATUAV (a local company specialized in UAV aerial imaging). In the summer of 2013 he participated at a Silicon Valley conference on 3D printing and came back to Barcelona with the idea of adapting this technology for UAV applications.

It was the mix of a dedicated student, the University environment and entrepreneurship that made it possible to develop the 1st 100% 3D printed UAV in Barcelona. On a global scale this only the 2nd 3D printed UAV in Europe and the 5th in the world.

The study demonstrated the feasibility of using rapid manufacturing technology, more specifically consumer 3D printing, in Unmanned Air Vehicle design.

The Barcelona UAV has been designed with Autodesk software, 3D printed with PLA material on a RepRap BCN 3D+. Table 1 shows its final specifications.

Table 1: Barcelona 3D printed UAV specifications

The major aim of the project was to obtain the best weight performance of any UAV design. Comparing the Barcelona UAV with the reference UAVs and the best weight performance technology currently available (high density foam such as used in the Multiplex Easy Star II RC plane) it becomes clear how successful this project has been:
Table 2: Referenced UAV comparative results to Barcelona UAV

Figure 1: Comparative graphic between referenced UAV
The Advanced Manufacturing Research Center of the University of Sheffield, and BOEING developed a 3D printed UAV (see Figure 2) that has the 2nd best weight performance, but it is a flying wing glider. Taking into account that the other references have been evaluated including the engine weight, VAST AUAV or SULSA can be considered as having the 2nd best weight performance.
Figure 2: AMRC 3D printed UAV
The Massachusetts Institute of Technology, Lincoln Laboratory, developed the so-called VAST AUAV in 2013 (see Figure 3). This project was co-sponsored by the US Air Force and RAPID 3D IMAGING. This interesting UAV has a carbon fiber reinforced polymer (CFRP) fuselage beam. It is therefore safe to assume that if VAST was 100% 3D printed, it would be heavier than it is with its current mixed technology design. This leaves the SULSA as having the 2nd best weight performance in the balanced comparison of the weight performance for existing 100% 3D printed UAVs.

SULSA was developed by the University of Southampton, a UAV that is the 1st 3D printed plane and the 2nd best weight performance in the world. SULSA, with 6.174,68 € budget, has been sponsored by a UK-based 3D-printing firm, 3T RPD2.

The Barcelona UAV has only 28% of SULSA's weight and taking into account the wingspan, it is 37% of SULSA's weight/wingspan ratio which underlines the amazing result of this project.

In order to compare the Barcelona UAV with the MULTIPLEX Easy Star II (an entry level model airplane), it is necessary to compare the ratio of the weight / total span (wing + fuselage) because of the similar sizes, see Table 3.
Table 3: Barcelona UAV comparison with the best weight performance in traditional technology
The Barcelona 3D printed UAV has the same weight performance than injection technology of high density foam, ELAPRON®. Since this evaluation has balanced the alternatives, the fuselage, wing and tail cost have been compared in order to tiebreaker them.

The Multiplex Easy Star II costs 78.90€, including taxes but excluding avionics. The Barcelona UAV costs 18.63€, including taxes and energy cost but excluding the RepRap BCN 3D+ printer cost. Taking into account that RepRap has a 3D printing service in the Barcelona UPC Campus with a cost of 0.12 €/cm3, the cost of producing the Barcelona UAV is 44.71€, including taxes. Therefore the Barcelona UAV cost is only 57% that of the Easy Star II.

This is an amazing result of this project because it demonstrates the feasibility of 3D printing technology in UAV applications. This document has demonstrates that the 3D printing service of the Barcelona UPC Campus is the best option for 7 or less units and in case of more than 7 units of the 3D printed UAV the best option is to buy your own low cost 3D printer.

2. How Did You Design the UAV? Did You Have to Learn Any New 3D Modeling Skills?

The Barcelona 3D printed UAV has been designed using Autodesk software, with a student license. You need such a powerful software in order to fully apply your knowledge. Having a clear target also greatly helps to sharpen your 3D modeling skills. For this project the target has always been to design a new UAV design, in view of manufacturing it using 3D printing technology.

Over time, I tested various CAD software. Today, I find AUTOCAD, INVENTOR and 3DS MAX to be useful design tools, since each has a great community of users that you can learn from to further develop your own skills.

CAD skills alone were not sufficient for this project though. The complete design cycle includes thinking, selecting, manufacturing, testing and reiterating. I had to apply the full breadth of my know-how to build the UAV:

Aircraft design, in order to design the UAV.

C++ programming, in order to optimize firmware configuration and G-Code parameters to obtain the high performance required for this specific application.

Statistics, in order to analyze the results of the printing in function of the configured parameters. More precisely, the weight in function of the Z axis height and printing speed.

Fluid mechanics, in order to analyze the deposition behavior of the fused material from the 3D printing process and to design cooling requirements for PLA parts in contact with the engine.

Materials science, in order to compute structural requirements for the used materials and sizing the design.

Flight mechanics, in order to compute the operational requirements for the remote control of the UAV.

DIY skills, in order to join parts and assembly the UAV.

3. What 3D Printer and what Material Did You Use to Print the Parts of the UAV?

All parts of the UAV were saved as . stl files and then sliced using slic3r. The wing has a rectilinear infill of near 0.3%. and only one perimeter. Both fuselage and tail have 0% infill.

Compared to the overall size of the UAV, the build volume of the RepRap BCN 3D+ is relatively small. Therefore, wings and fuselage had to be printed in sections that were then assembled to form the full size UAV. I experimented with various joining or welding techniques and ended up using a heat welding process. Using a standard soldering iron and left-over PLA material, I was able to join the different sections. As it turns out, the molten PLA distributed evenly into the joints, giving the bond a very high tensile strength.

A Few Thoughts on Materials

In my opinion, materials research will contribute to the most important developments in 3D printing over the coming years. Materials with different flexibility, mechanical properties, color and recyclability will be soon available for 3D printing users.

With the proliferation of dual extruder 3D printers, material flexibility will constitute an important development since this will allow for the creation of anisotropic parts. The possibility of 3D printing a blade using root flexibility for the first material and tip flexibility for the second and a controlled mix of them along the longitudinal axis, will become an improvement for fluid mechanic engineering.

Mechanical properties of the material can be modified by adding CF nanotubes or similar reinforcements. Nowadays there are already ABS materials with high mechanical properties. The minimum perimeter thickness, near 500 μm, and the maximum part size of 3D printing technology are still the main limitations. Therefore improving the Young modulus or stiffness of 3D printing materials will lead to new applications.

Color of the filament is an interesting feature for 3D printers with multi extruders because RGB or CYMK basic colors can be mixed to generate any color tone. This feature will increase 3D printing applications.

To my mind, recyclability is the most important performance for 3D printing technology for the simple reason that it allows users to have a lower cost rapid manufacturing tool. When prototyping you always generate waste and unused parts. Having the possibility to recycle this waste material would be desirable both from a cost and environmental point of view.

For the Barcelona UAV I used PLA, a biodegradable material. I believe this is essential for any applications where parts may go lost outside. Still, even with PLA you have to careful since its biodegradability also depends on the properties of the additives used in manufacturing the filament.

4. Could You Have Developed the UAV Without 3D Printing?

No, this would not have been feasible with standard technologies since many of the UAV parts constitute complex shapes that would either have been too costly or even impossible to mold.

5. What Did You Learn About 3D Printing by Working Through This Project?

3D printing constitutes the 3rd Industrial revolution. In the future, consumers will buy .stl files via the internet and print their objects at home or via a 3D printing service. This will affect traditional industries, supply chains, distribution and employment in totally new ways. Therefore, 3D printing technology must be analyzed and understood from a global and not only a local point of view.

Compared to other rapid manufacturing systems, 3D printing technology is a low cost way of transferring things from the world of the ideas to the real one. Therefore, 3D printer device selection played an important role in my project. The main requirements were cost, multi material availability, double extrusion capability, open-source philosophy and supplier proximity. The aforementioned performance requirements allow a designer to create something economically feasible, while using new materials and mixing different material properties to customize parts to very specific requirements. Firmware configuration is also important in order to improve the technology for a given specific application.

In order to test a new system's power and limitations you always need a bit of respect and a will to test things out. Respect is required since the 3D printer is not a toy and it constitutes an important device in the design cycle. Testing is required since this is the only way to completely understand the full depth of the technology that you have at your finger tips.

The project also made me understand the direct relationship between time, weight and cost. 3D printing is the only technology where investing time in weight reduction has a direct impact on cost reduction and manufacturing time reduction. Traditional technologies increase cost in function of the weight and manufacturing time reduction.

Last but not least, I learned a ton about joining 3D printed parts as this played an important role in assembling the UAV prototypes. As build volumes of 3D printers are still relatively small, the UAV had to be printed in sections which were then joined.

6. Based on What You Know About 3D Printing Now, Where Do You See the Biggest Limitations and Greatest Opportunities?

The biggest limitation is the PLA material because of its stiffness, mechanical properties and its density. New PLA materials with specific properties must be developed while maintaining the biodegradability.

The biggest opportunity I see is that a design can be digitally distributed and 3D printed anywhere in the world thereby giving you access to a worldwide network of beta testers. Anyone with a 3D printer and 0.5 kg of PLA can manufacture their own homemade UAV.

7. What's Next for the 3D Printed UAV?

Since the completion of the Barcelona UAV project, I have been thinking about the following development and improvements:

The use of conductive materials. Using a 3D printer with a dual extruder, one could imagine printing the UAV wings and fuselage of one material while using conductive material to print the wiring required for the avionics.

Anisotropic parts, because propeller blades or wings could be designed with specific flexing behavior according to aerodynamic optimization.

Specific Infill for lightweight parts, because the existing patterns are only focused on support material and mechanical properties. This study has designed a lattice 3D honeycomb interesting for this development.

An advanced joining system, because the UAV requires parts joining and heat welding is a simple technology. This new system must be a heat technology able to be configured by temperature adjustment and surface selection, inside or outside the slices.

I am currently finishing my studies and while I have no concrete plans for the future of the 3D printed UAV yet, I sure think about it.

By the way, upon graduation I'll be looking for a nice job!

Making parts for a jet engine using a 3D printer is - despite what you may hear - not cheap. The powder used by the printer to build up the part - layer by microscopic layer - is expensive, and the 3D printer itself has a seven-figure price tag. Plus, the component still requires costly finishing work after it emerges from the additive manufacturing process.

"Given the high expectation built around the Company, my priorities would be to concentrate on operational excellence, and build the company as technology powerhouse," said T. Suvarna Raju upon taking position as the new Chairman at Hindustan Aeronautics, Ltd. (HAL) at the beginning of this month.

Raju's vision for HAL is to move India's only manufacturer of military aircraft ever mor e firmly into the realm of world-class aerospace firms, and is embracing his government's push toward "Made-in-India" labels affixed to high-quality products. He recognizes that "the Best of Technologies can never be bought, it can only be developed," and to that end is enhancing HAL's focus on research and development. HAL has developed a strategic business unit (SBU) to focus on the unmanned aerial vehicle (UAV) market, which in India alone has the potential to be worth $2 billion.

As it turns out, 3D printing will be along for the ride.

HAL is looking to additive manufacturing to create components for a 25-kilonewton (kN) aircraft engine, with the overall project valued at Rs 458 crore (over $73 million USD). Raju recently told India's Deccan Herald that the project was going smoothly until recently, when a supplier reneged on the deal. The 6-and-a-half-year-long project requires the critical components that this particular vendor was due to contribute, and so their backtracking could easily have halted progress quite rapidly. HAL, however, is not one to give up so quickly, and instead of looking to that outside supplier or trying to find another, the company purchased its own 3D printing equipment.

The company's first engine design is ready for display; an operational version of the engine will be shown next week at Aero India, "Asia's Premier Air Show." HAL will have the unit on display at their exhibition space.

HAL's successful designs also include an 8-kg UAV, which will also be shown at Aero India. The next step there is creating a 10-kg rotary unit, for which R&D is already underway, including work with IIT Kanpur. Researchers there have successfully created a quadcopter, so further UAV development seems right on track.

Raju "would like HAL to grow as a knowledge based organization," which dovetails with his drive toward company R&D activity. Under Raju's oversight, HAL has earmarked 10% of its post-tax profit for R&D ventures. Further adding to their research and development efforts is HAL's drive to set up chairs in academia, including at campuses such as IIT Channai (working on gear boxes), IIT Mumbai (communications), IIT Kharagpur (radar and electronic warfare), and IIT Kanpur (UAVs).

Under Raju's direction, HAL seems to be on the right track toward tech-based progress. India's sole military aircraft producer seems to be increasingly well positioned to lead the country's charge forward, and 3D printing capabilities at the company will serve only to enhance that process. Rapid prototyping will lead to improvements in iteration - a certain benefit in creating such ambitious projects as the 25-kN one on the table now.

Let us know what you think about India's development in the 3D printing space in the HAL 3D Printing for Engine Components forum thread over at 3DPB.com.

NASA & Aerojet Rocketdyne Use 3D Printing to Expedite Independence from Russia

# data[].attributes.body
Aerojet Rocketdyne and NASAStennis Space Center for test stand support and test services of the the company’s AR1 multi-element pre-burner and main injector. This new agreement will build on and solidify the relationship between AR and NASA’s Stennis Space Center, as currently Aerojet Rocketdyne’s two other engines are being tested at Stennis Space Center.
The AR1 features advanced oxygen-rich staged combustion kerosene technology and provides 500,000 pounds of thrust making it compatible with many American launch vehicles. Two combustion engines are used in the AR1 engine, a main injector/combustion chamber and a pre-burner. Both of these devices are critical to the function of the engine and must operate under extreme pressure and temperature environments.  As part of the development process, AR has taken a tip from NASA’s recent experiments with additive manufacturing at Marshall Space Flight Center. They conducted a subscale pre-burner hot-fire test at Marshall using 3D printed hardware. Not only does this help reduce the timeline and cost of development, but it gets AR on board in what looks like the future in aerospace manufacturing.

Julie Van Kleeck, Aerojet Rocketdyne vice president of Advanced Space & Launch says,“This is another example of Aerojet Rocketdyne’s focus to maintain schedule for the United States to be able to have AR1 ready to fly in 2019, to keep our country on track to end dependence on Russian engines.”

Aerojet Rocketdyne’s 3D printed multi-element preburner injector under test fire.

In order to meet the agreement, NASA Stennis will have to modify their E-1 complex, cell 1 test stand over six months in order to reconfigure it to conduct AR1 staged combustion testing. Van Kleeck adds, “We are using a stair step approach to eliminate the highest risk items first in our AR1 engine development program to ensure earliest possible delivery. By incorporating additive manufacturing and other new processes, materials and techniques into our plan, we offer the Nation a timely, cost-efficient path to end reliance on the Russian engines.”

Today we'll tell you a story about D-Shape.. a 3D Printer that prints entire houses.

D-Shape

Italian inventor Enrico Dini has developed D-Shape. An enormous 3D printer that can print entire buildings out of sand. It works as followed. First the printer sprays a thin layer of sand followed by a layer of magnesium-based binder. The glue turns the sand into solid stone, which is built up layer-by-layer from the bottom up to eventually form an entire house.

Documentary on Enrico Dini

Marc Webb and Wake-Walker are making a documentary about Enrico Dini called 'The Man Who Prints Houses'. Check out their teaser.

Contour Crafting

Contour Crafting is a form of 3D printing that uses robotic arms and nozzles to squeeze out layers of concrete or other materials, moving back and forth over a set path to fabricate a large component. Contour Crafting has great potential for creating low-cost, customized buildings. Just think about the possibilities of 3D printing in construction.
Additionally it will also have an affect on constructing rapid shelters after natural disasters, or operational structures on the moon out of moon dust, and cheap houses for people in impoverished countries. To visualize this method of constructing you have to watch the video below. It's pretty old (2010) but new to us. It shows how a straight hollow wall with fiber reinforced concrete is constructed in literally minutes. Really a must see!

3D modelling has enhanced architechtural presentations - Invention of CAD software

# data[].attributes.attachment_link.readable_text
I believe almost everyone knows about the technical drafts-which contained ancient airplane models, machinery etc.-drawn up by one of the words most foremost geniuses, Leonardo Da Vinci- who just happened to be a scientist, inventor, architect, lawyer, and doctor, all at the same time. His manuscript was sold between the years of 2000-2003 to Bill Gates for a whooping sum of $600,000,000(approximately) breaking all records on book sale.

The book contained some innovative ideas-at least in his time-which were roughly sketched in 2 dimensions(2D) and it gives us a glimpse into the way architectural and mechanical drawings where drafted in those days as well as the presentation models that must have been used in the past. This method of drafting as well as presentation was so limited in many ways that I wouldn't bother to least them, which brings us to the topic of the day-how 3D modeling has enhanced architectural presentations.

The Invention of CAD Software

There are few technologies that have had as much impact to drafting and the architectural industry like the advent of CAD in 1961 by Ivan Sutherland; he designed the first Computer-Aided-Design Software to run on the large Unix systems of the mid-19th century. This ground breaking innovation was destined to revolutionize the way architects draw and handle presentations.

The Innovative Architectural Presentation Changes

3D modeling did not only change the way we represent diagrams, building plans and drafts but also had a substantial effect on how presentations and exhibitions of architectural designs could be done. These revolutionary qualities of 3D CAD software include:

Realistic Representations-gone are the days where an architect had to physical design a card board model to provide individuals with a life-like representation of his/her plans because with modeling on CAD platforms, one can now easily represent design plan in 3 dimensions which would show observers every part, dimension and documentation of that particular plan.

Incorporating 3D designs in Holographic Representations-the new technology which involves the use of holographs to represent objects, designs and components in virtual space cannot be performed without the use of CAD. This because the designs to be incorporated must first be designed on a 3D modeling/Animation software before transferring to the holographic design software.

The Beauty of Animation-most 3D CAD software applications are now designed to be an integrated platform which can draw 2D drafts, create 3D models and animate them to actually give observers a realistic view of how a project would function.

The Benefits of 3D CAD in Architecture

The benefits of CAD use are numerous but I shall try to outline just the most important ones and how they affect our lives, the architectural design process and enhance productivity.

Speed and Accuracy-no longer do architects need to cross-check drawing papers, tear them up and re-draft all over again for with the use of CAD, you would be intuitively shown every dimensional, extrusive or intrusive change you make to your model. Thereby eliminating the rooms for human error and also cutting the time taken to complete an architectural draft by traditional means in half.

Affordability-yes we all know that the cost of purchasing the initial software can be quite steep and the annual license renewal also comes into play but when compared to the capital spent in purchasing traditional drafting tools and the time taken to complete a task traditionally, the money spent on CAD software steals the show.

Networking Amongst Architects-3D modeling software platforms now come with innovative networking features and interfaces that allow professionals share information and also work simultaneously on a particular project.

Most people think of 3D printing as a prototyping technology rather than a production technology. That is, they would never think to use it for making large batches of end use parts. And most of the time they'd be completely right.

However, there are some interesting circumstances when the most common and cost effective method of 3d printing (fused deposition modelling) is actually the best choice of production technology.

Of the dozen common methods of plastic manufacturing, 3d printing offers its own unique set of advantages and disadvantages.

3D printing favors customization and is excellent for small quantity batches. It allows you to make parts with as much variety and complexity as you want at no additional cost. It allows you the flexibility of changing a product after production has started, also at no extra cost.

On the downside 3D printing can't offer any economies of scale. It is essentially no cheaper on a per- unit basis to make a large batch of parts than it is to make one.

For true high volume production you need a process like injection molding, which favors repetition and standardization. For a visual aid I borrowed this graph from the book 'Makers: The New Industrial Revolution' by Chris Anderson. It uses plastic ducks to illustrate the strengths and weaknesses of injection molding vs 3d printing in volume.

But what about those 'special circumstances' for using a printer to make large batches? Well I can think of two great examples.

In 2012 Brook Drumm created the The Original Printrbot and used Kickstarter to raise over $830,000 from 1,800 backers. By my estimation he had to build about 1,200 sets of PrintrBot parts, with each set containing 22 total plastic parts, 16 of which were unique.

He clearly had to make a lot of parts but injection molding would not have been suitable for this task. For starters it would require a very large and complex (read expensive) mold to make that many parts at once. But the real problem was that those parts were too thick and had too many undercuts to be produced in a mold.

Similarly, CNC machining those highly detailed parts would have cost a fortune.

So how did he do it?

This is a special case because his product was a 3d printer made of printed parts. He used the parts he made to make machines to make more parts. Brook called it the 'bot farm', and I estimate that he had at least 10 machines running at the same time.

At $500 per machine his setup cost would have been $5,000. Which is high but the machines could also be sold off when he finished or used for other projects. Using multiple FDM 3D printers was truly the best way to manufacture that set of parts in large volumes.

My other example also uses bot farming, and shares possession of over 50 Makerbot Replicator 2's making it one of the biggest printer farms in the world.

The Robohand Organization creates 3D printed anatomically driven, custom fitted, functional mechanical devices to provide an affordable alternative to standard prosthetics for those in need.

A 3d printing farm is perfect for this application because it allows them to make lots of parts while retaining their ability to customize those parts for an individual's specific prosthetic needs. And because the printer farm is shared with a college, their production capacity is never wasted in idleness.

The sharable nature of 3d printing files also allows them to indirectly help a much larger population. Their designs are all open source, so you could also say these parts are being produced in mass albeit over a large distribution of people.

Those are the best examples I can think of for using 3d printing as a production technology. Surely I'm missing some other good ones, can you think of any?

# data[].attributes.attachment_link.readable_text
3D Printers can use a wide range of materials, including plastics, resins, metals, ceramics and more.

The most popular material is plastic, and most of the home / desktop style printers print objects using plastic, however some of the higher-end printers are capable of printing using many different materials.

Currently some of the Objet range of printers support up to 107 materials. Take a look at the Objet Materials page to learn more about the type of materials their printers support.

Plastics

At the moment the majority of 3D Printers, especially the low cost systems, print using a technology called 'Fused filament fabrication (FFF)', these printers currently tend to print using one of the following materials:

PLA Filament

PLA (Polylactic Acid) - PLA is probably the easiest material to work with when you first start 3D printing. It is an environmentally friendly material that is very safe to use, as it is a biodegradable thermoplastic that has been derived from renewable resources such as corn starch and sugar canes.

ABS Filament

ABS (Acrylonitrile butadiene styrene) - ABS is considered to be the second easiest material to work with when you start 3D printing. It's very safe and strong, and widely used for things like car bumpers, and lego (the kids toy).

PVA Filament

PVA (Polyvinyl Alcohol Plastic) - PVA plastic which is quite different to PVA Glue (please don't try putting PVA Glue into your 3D Printer, it definitely won't work). The popular Makerbot Replicator 2 printers use PVA plastic.

Powders

The higher end printers, can use various powder based materials to create 3D objects, these materials can include:

Polyamide - Which is a strong and flexible material that allows a high level of detail to be achieved. Polyamide objects are constructed from a white, very fine, granular powder.

Alumide - Is a Polyamide-like material with a distinctive sandy and granular look, that is a rigid and strong material. Alumide objects are constructed from a blend of gray aluminum powder and polyamide, a very fine granular powder.

Multicolor - A full color material with a sandy and granular appearance. Models made out of multicolor are constructed from a fine granular powder.

Resins

Resins are also a material sometimes used in 3D Printing, although design freedom is limited due to the structure necessary to support the objects during the printing process. The following are examples of some resins that can be used:

High detail resin - Objects made out of high detail resin are constructed from a photo polymeric liquid. This material is ideal for small and/or very finely-detailed visual models, where high detail is required.

Paintable resin - Objects made out of paintable resin have a smooth surface and will look beautiful painted.

Transparent resin - Objects made out of transparent resin are constructed from a hardened liquid. The material is strong, hard, stiff, water resistant by nature, and of course, transparent. Transparent resin is suited for models needing a good, smooth, quality surface with a transparent look.

Other Materials

Some metals and ceramics are also being used in 3D Printing, here are a few examples:

Titanium - Is very light and the strongest 3D printing material available. Objects made from titanium are printed using titanium powder that is sintered together by a laser.

Stainless steel - Object produced in stainless steel are 3D printed using a stainless steel powder that is infused with bronze material. Stainless steel is the cheapest form of metal printing, very strong and suitable for very large objects.

Bronze - Objects produced in bronze are 3D printed in using a bronze powder that is infused with bronze. Bronze is an affordable and strong material for printing models in metal.

Brass, Silver, Gold - Can also be used in 3D printing, although involves printing a wax mould which is then filled with the molten material.

Ceramics - A 3D printing material that has a shiny appearance, is heat resistant, recyclable and food safe. Models made out of ceramics are constructed from alumina silica ceramic powder, then sealed with porcelain and silica and glazed. A perfect material for home decor items and tableware.

Material Samples

If you are thinking about purchasing a 3D Printed object via one of the many 3D Printing Service companies, we would recommend purchasing a sample kit as this is a great way to look at the different types of printed materials before deciding on a particular material for your printing requirements. A couple of the most popular 3D Printing Services are i-materialise and Sculpteo, and you can find their sample kits here:

Materials that the 3D Printers use

To find out what sort of material each printer uses, take a look at the technical specifications on the manufacturers web site, it should provide this information, alternatively contact the manufacturer or supplier.

Different Types Of 3D Printing Technologies

Different Types Of 3D Printing Technologies

# data[].attributes.body
There are basically 5 different 3D printing technologies being used in the dental industry today: Digital Light Projection (DLP), Jet, Stereo-Lithography Apparatus (SLA),Selective Laser Sintering and Direct Laser Metal Sintering (DLMS). Each system varies in the materials available, how those materials are solidified, and how they can be used.

1.Digital Light Projection (DLP) 3D printing:

The working material for Digital Light Projection is UV- and visible-light sensitive and held in a reservoir. A wiper blade spreads material uniformly across the build platform after each layer is printed. DLP then takes advantage of the same technology used in certain television sets and presentation projectors to illuminate the outline of all of the parts simultaneously. The printed material is cured using a lamp or LED light source depending on printer model.

Typical vertical resolution is 13 µm to 50 µm with very good accuracy and excellent surface finish. Post-print processing involves removal of support material by rinsing.

2.Jet (PolyJet/ProJet) 3d Printing

3D jet printing is just what it sounds like, a more sophisticated big brother of the inkjet printer. Instead of ink being jetted or sprayed onto paper in a single layer, a resin or wax is jetted onto support material, and then onto previously sprayed layers until the part begins to take on depth and shape (Figure 1).

3D Jet printers may have a single print head like a computer printer, or they may have multiple heads to cover the width of the working platform. Either the print head moves across the working platform, or the platform moves back and forth under stationary print head(s). The 3D Systems and Objet printers use a UV lamp or a light source to harden the resin or wax after each layer is jetted. The Solidscape printer jets a heated wax that cold-cures in place and does not require exposure to a UV light source.

Typical layer thickness ranges from 16 µm to 50 µm with excellent accuracy and surface finish. Post-printing processing is simply removal of the support material, usually with a water or oil bath and simple rinsing. Most systems have self-cleaning print heads, so no user intervention is required. The curing light source, if necessary, is usually a Xenon lamp with a long service life.

An example is the The ProJet™ CPX 3000 3D Production System. It uses proprietary Multi-Jet Modeling (MJM) technology combined with new VisiJet® CPX200 wax build Material and new VisiJet® S200 dissolvable wax support Material to produce reportedly 100% RealWax™ patterns that are designed to perform like injected wax patterns in lost-wax casting processes.

3.3D printing Stereo Lithography Apparatus (SLA)

Stereo Lithography Apparatus (SLA) 3D printing uses a UV-sensitive liquid resin as the working material. A UV-laser is projected on and moves across the reservoir of the resin build material, illuminating and hardening the liquid resin only in the areas where the part is being printed. If multiple parts are being printed, each part is traced on the resin by the laser. The platform holding the part or parts lowers after each layer is printed, and a wiper blade spreads more build material uniformly across the working space. The UV laser makes another pass, tracing the outline of the next layer for each part in the print job. The process is repeated layer by layer until the job is complete. SLA technology allows for varying the layer thickness throughout the printing process. Some layers can be 100 µm thick where accuracy is not critical and then dialed to 50 µm or less when greater accuracy is required.

SLA printing technology is available with a wide variety of materials. A 25-µm to 50-µm layer thickness is achievable with excellent accuracy and good surface finish. SLA typically has slower build times due to the laser outline of each part. Post-print processing may require cutting the final part from the support material, removal of excess material, and the parts placed in a UV oven for final curing.

4.Selective Laser Sintering (SLS)

Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into a mass that has a desired 3-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.

5.Direct Laser Metal Sintering (DLMS)

DLMS uses a metal powder and SLS typically uses a plastic powder. The powder is spread across the working platform. A laser traces the outline of each part being printed, fusing (DLMS) or melting (SLS) the powder to the layer below it. The platform is lowered, a new layer of material is spread across the platform and the process repeated until the print job is complete.

DLMS technology has traditionally only been available for printing non-precious metals. Recently, Argen has developed its own materials and techniques for the EOS machine that allows them to provide both non-precious and noble metal copings. Post-print processing requires cutting off the support material.

Its a method of 3D printing developed by MIT, and uses a technique called Machine Vision

Machine vision is almost exactly what it sounds like. While conventional 3D printers convert model data into a path which they obliviously follow (with machine vision uses a 3D scanner to constantly feed data back to the printer, allowing it to check the object produced against the original model and self-correct any errors, meaning MultiFab requires much less human supervision.

Machine vision also allows the printer to adapt in complex manufacturing processes. For example, if a user adds a specialized component into the print bed, MultiFab is capable of recognizing the component as part of the model it is creating and working around it. With this process, CSAIL has so far been able to print lenses for LEDs, a plastic handle for a metal blade, and smartphone cases that print around the smartphone.

As techniques, softwares, and materials improved, the chairside use of CAD/Cam (use within dental offices/surgeries) increased. For example, the commercialization of a software Cerec by Seimens made CAD/CAM available to dentists who formerly would not have had avenues for using it.

Traditionally, much of the work relied heavily upon less accurate alginate impressions, which were turned into stone (gypsum) models of the hard oral environment. These models were used to manufacture orthodontic appliances, such as acrylic retainers, mouth guards, spacers and arch expanders.

The printer jets layers of curable liquid photopolymer in 16-micron layers with accuracy as high as 0.1 mm, which appreciably enhances the dental models’ and medical devices’ quality.

For its 3D-printed parts, NASA uses ABS, PCABS and polycarbonate materials. FDM, patented by Stratasys, is the only 3D-printing method that supports production-grade thermoplastics, which are lightweight but durable enough for rugged end-use parts

A summary by Jeelani Shaik

The scientists at NASA need to be extremely careful and calculating about their vehicle, which is called Desert RATS (Research and Technology Studies) they use for deep space explorations. They only have one shot at this.

They need to make precise trade-offs to deal with the terrain, atmosphere, and various gravitational fields which is generally associated with such type of exploration.

And they can best decide and produce such vehicles using high precision 3D printers to perfectly calculate and allocate different materials to build their vehicle which can face all the challenges anticipated by them. And this method is much more convenient compared to previous practices.
