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.

Cody Rutledge Wilson (born January 31, 1988) is an American gun rights activist and crypto-anarchist. [1] [2] He started Defense Distributed, a non-profit organization which develops and publishes open source gun designs, so-called "wiki weapons" created by 3D printing and digital manufacture.
Ultimaker is a 3D printer manufacturing company based in the Netherlands, with offices and assembly lines in the US. [1] They make fused filament fabrication 3D printers, develop 3D printing software, and sell branded 3D printing materials. [2]
Their product line includes the 3D printer series PEGASUS. The makeR 3D printers are compatible with polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), thermoplastic polyurethane (TPU), high-impact polystyrene (HIPS), polyvinyl alcohol (PVA) and some specials materials for industrial needs, such as PLA filament mixed with particles of metals which through sanding 3D printed parts ...
Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.
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 ...
