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.
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.
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]
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.
Typically desktop 3D printers can make small plastic 3D objects. They use a roll of thin plastic filament, melting the plastic and then depositing it precisely to cool and harden. They normally build 3D objects from bottom to top in a series of many very thin plastic horizontal layers. This process often happens over the course of several hours.
The Way Things Work is a 1988 nonfiction book by David Macaulay with technical text by Neil Ardley. It is a whimsical introduction to everyday machines and the scientific principles behind their operation, describing machines as simple as levers and gears and as complicated as radio telescopes and automatic transmissions. Every page consists ...
The first methods for rapid prototyping became available in mid 1987 and were used to produce models and prototype parts. Today, they are used for a wide range of applications and are used to manufacture production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics.

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.
