Microelectromechanical systems ( MEMS, also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems and the related micromechatronics) is the technology of microscopic devices, particularly those with moving parts. It merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines in Japan, or micro systems technology ( MST) in Europe.

An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion

A 2d and 3d cutter is a high powered laser that cuts material such as thin metals or woods, used mostly for industrial purposes. They make precise and clean cuts, it is also is very fast which makes it efficient. It is first designed through a computer and then sent through a laser cutter to give you the design.
2D recognizes the surface of an object;3D, all sides.
The cutters are used to cut big, hard materials such as parts of aircraft, buildings, and cars.

OLED (organic light emitting diode) is a type of display that is used in some monitors. OLED has wider colour gamut, better viewing angle, and higher contrast ratio (since each pixels can turn off); however it has a shorter lifespan compared to LCD.

Digital Light Processing (DLP) is a display device based on optical micro-electro-mechanicaltechnology that uses a digital micromirror device.

i.e. It uses multiple mirrors to display images onto a screen.

The technology used in various enterprise-level projectors as well as small educational environments, including theatres and universities.
DLP Cinema Systems during the late 90s and early 2000s installed many DLP projectors to release Star Wars I, Toy Story 2, and many other digitally created/edited movies.
Belgian company Barco and Japan's NEC are the two most significant companies which produce such projectors.

Boons:

Smooth, perfect geometry display

Light Source is replaceable, thus resulting in longer lifespan and economically-efficient management

Lightweight

Banes

Replacement of the lamp has to be done often

Response time is slow. Therefore, playing video games or user-interactive software is not recommended.

LED monitor or a Light Emitting Diode .  An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video display.  Their brightness allows them to be used outdoors where they are visible in the sun store signs and billboard. There is a significant difference between the LCD monitor and the LED monitor.

LCD (Liquid Crystal Display): A prevalent model of HDTVs, LCDs are flat panel displays through which light can pass or be blocked. The LCD doesn't produce its own light; this is done by additional lighting (see backlit and edge-lit for more info). LCD HDTVs are available in a variety of sizes and have wide viewing angles, making them ideal for almost any size room.

LED (Light Emitting Diode): A semiconductor device that produces light from electricity. LEDs are often used to backlight LCD displays, which results in a clearer picture.

1. It is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper, plastic, or other substrates.

2. most commonly used type of printer

3. Advantages: quiter than any other printers, higher resolution, no warming up time, lower cost per page

4. Movement of a nozzle => Spread of small ink particles to create an image

5. Injket documents can have poor to excellent archival ability and are gradually faded.

6. A microchip that communicates the estimated ink level to the printer may cause the printer to display an error message, or incorrectly inform the user that the ink cartridge is empty.

Sean Kim:

An LED monitor (short for Light Emitting Diode) or LED display is a flat screen, flat panel computer monitor or television. It has a very short depth and is light in terms of weight. The actual difference between this and a typical LCD monitor is the backlighting.

Advantage of LED Monitors are:

Typically are less expensive

Broader dimming range

Overall more reliable

They run at a lower temperature, and consume much less power, as few as 20 watts

Higher dynamic contrast ratio

Longer lifespan and less environmental impact

Usage
- Computer monitor
-  HD TV screen
-  Movie theatre screen

DEFINITION
- computer-aided manufacturing (CAM) device that creates three-dimensional objects. The printer receives digital data from a computer as input. However, instead of printing the output on paper, a 3D printer constructs a three-dimensional model out of a custom material.

HOW DOES IT WORK
begins in a computer aided design (CAD) software system, where its blueprint is created. The blueprint is then sent from the CAD system to the printer in a file format known as a Stereolithography (STL), which is typically used in CAD systems to design 3D objects. The printer then reads the blueprint in cross-sections and begins the process of recreating the object layer-by-layer, just as it appears in the computer aided design. In the picture below is an example of a 3D printer called the FlashForge.

APPLICATIONS
- device that creates physical objects using materials such as metal alloys, polymers, plastic, and at times food ingredients.
- Used in multiple fields including engineering, dentistry, archaeology, biotechnology

Definition

3D(three-dimensional)printing is process of making three dimensional solid objects from a digital file. It enables people to produce complex (functional) shapes using less material than traditional manufacturing methods.

Qualities

Objects are created by adding or depositing layers of material, not subtracting or cutting out pieces from a block of material.

The computer file with details about your model must be converted into slices the printer will create layer by layer.

Time depending on a size and complexity

Application

Medical

Bioprinting

3D printed implants

Dental

Food

Fashion

Education & New jobs

Architecture

Modeling

Types

Stereolithography(SLA)

Digital Light Processing(DLP)

Fused deposition modeling (FDM)

Selective Laser Sintering (SLS)

Selective laser melting (SLM)

Electronic Beam Melting (EBM)

Advantage

Faster speed

Single step manufacture

Complexity and design freedom

Customization

Disadvantage

Limited Materials

Questionable Accuracy

Qualities

Objects are created by adding or depositing layers of material, not subtracting or cutting out pieces from a block of material.

Because objects are created by adding layers, the computer file with details about your model must be converted into slices the printer will create layer by layer.

Printing a three-dimensional object can take hours or days to complete, depending on the complexity and size of the object.

Cost is based on materials used, among other factors. In contrast, if you buy a piece of wood then cut out pieces to create your object you pay for the original piece of wood.
