2. 3D printing processes - Wikipedia

   en.wikipedia.org/wiki/3D_printing_processes

   The cost of 3D printers has decreased dramatically since about 2010, with machines that used to cost $20,000 now costing less than $1,000. [91] For instance, as of 2013, several companies and individuals are selling parts to build various RepRap designs, with prices starting at about €400 / US$500. [92]

   At the 2017 Consumer Electronics Show, Markforged unveiled the Metal X, which is a 3D printer capable of 3D printing metal parts at a low cost, under $100k. [8] The process has been referred to as ADAM (Atomic Diffusion Additive Manufacturing) technology and it has an in-process laser inspection for dimensional accuracy. [5]

5. 3D printing - Wikipedia

   en.wikipedia.org/wiki/3D_printing

   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.

6. Extruder (3D printing) - Wikipedia

   en.wikipedia.org/wiki/Extruder_(3D_printing)

   A 3D printer extruder is a filament feeding mechanism used in many fused filament fabrication (FFF) 3D printers. There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely ...
