The United States Air Force has begun to work with 3D printers, and the Israeli Air Force has also purchased a 3D printer to print spare parts. [ 114 ] In 2017, GE Aviation revealed that it had used design for additive manufacturing to create a helicopter engine with 16 parts instead of 900, weighing 40% lighter and being 60% cheaper.
In the United States, the Hill Air Force base is using 3D printed parts in repair of fighter jets. [76] Higher education has proven to be a major buyer of desktop and professional 3D printers. [77] Significant desktop 3D printer purchases by both K-12 and universities helped sustain a desktop 3D printer market that had problems in 2015–2016. [78]
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
The original printer, christened in 2019, was certified by Guinness World Records as the world’s largest polymer 3D printer, the university said. It was used to create a 600-square-foot, single-family home made of wood fiber and bio-resin materials that are recyclable. Dubbed “BioHome3D," it showed an ability to quickly produce homes.
3D Systems manufactures stereolithography (SLA), fused deposition modeling (FDM), selective laser sintering (SLS), color-jet printing (CJP), multi-jet printing (MJP), and direct metal printing (DMP, a version of SLS that uses metal powder) systems. Each technology uses digital 3D data to create parts through an additive layer-by-layer process.
The market for 3D printers has grown tremendously over the past several years. According to Wohlers Report 2018, 3D printer Market reached 7.3 billions $ in 2017, with +21% growth over the previous year. [1] The market is mostly B2B right now, because 3D printing is still a complex process.
OpenSCAD is a free and open source software that uses scripting to design 3D objects. [16] Many 3D printers can be upgraded with 3D-printed parts. Thingiverse users produce many improvements and modifications for a variety of platforms. Popular examples of community-based 3D printer projects include the RepRap project and the Contraptor project ...
