Custom, 3D Printed Earphones from Normal: If you visit the New York City storefront, you will think you have walked into an Apple store. The store is elegant and intensely (in the best way possible) customer-focused. When I visited, I was immediately greeted and asked if I would like something to drink (it was a hot day) and then a few more questions. You can see Stratasys 3D printers working away right there in the store.

3D printers in aerospace are commonly used to manufacture structural, low volume metal that mount complex life saving systems to the interior wall of a plane.
3D printing with Material Jetting is able to produce multicolor designs with a surface finish comparable to injection molding.
It also helps geometric design freedom and it allows the consolidation of multiple parts into single component.
Some examples are...
Engine compartment
Cabin accessories
Air ducts

1. Construction 3D Printing (c3Dp) or 3D Construction Printing (3DCP) refers to various technologies that use 3D printing as a core method to fabricate buildings or construction components. Alternative terms are also in use, such as Large scale Additive Manufacturing (LSAM), or Freeform construction (FC), also to refer to sub-groups, such as '3D Concrete', used to refer to concrete extrusion technologies.

1. The building-on-demand (BOD) by COBOD International, a small office hotel building, with a 3D printed wall and foundation structure. The first building of its kind in Europe.

There are a variety of 3D printing methods used at construction scale, these include the following main methods: extrusion (concrete/cement, wax, foam, polymers), powder bonding (polymer bond, reactive bond, sintering) and additive welding. 3D printing at a construction scale will have a wide variety of applications within the private, commercial, industrial and public sectors. Potential advantages of these technologies include faster construction, lower labor costs, increased complexity and/or accuracy, greater integration of function and less waste produced.

A number of different approaches have been demonstrated to date which include on-site and off-site fabrication of buildings and construction components, using industrial robots, gantrysystems and tethered autonomous vehicles. Demonstrations of construction 3D printing technologies to date have included fabrication of housing, construction components (cladding and structural panels and columns), bridges and civil infrastructure[1], artificial reefs, follies and sculptures.

The technology has seen a significant increase in popularity in recent years with many new companies, including some backed up by prominent names from the construction industry and academia (Purdue University). This led to several important milestones, such as the first 3D printed building (Winsun), the first 3D printed bridge (D-Shape), the first 3D printed part in a public building (XtreeE), the first living 3D printed building in Europe and CIS (Specavia), the first 3D printed building in Europe fully approved by the authorities (COBOD International), among many others.
