3D Printing

3D printers make it possible for DIY production of plastic, resin, and metal parts that, up until recently, were otherwise very difficult or expensive to create on a small scale.
DIY Machinery Leveling the playing field in favor of resilient small scale manufacturing

A 3D printer connects to a computer and, using stepper motors to move a print head that extrudes resin or plastic, 'prints' a three-dimensional object that is modelled on the computer.

3D printers make it possible to manufacture specialty parts in order to build and repair complex machinery at a local level.

Although 3D printers generally use commercial printer filament, 3D printers have been made that directly recycle and use plastic waste.

3D Printing Resources

RepRap


An open-source 3D printer that is designed to be able to print all of its own plastic parts. Plant-based, biodegradable PLA (Polylactic acid) filament can be used in RepRap 3D printers.

PLA filament


Polylactic acid or polylactide (PLA) — a biodegradable *thermoplastic aliphatic polyester* derived from renewable resources, such as corn starch, cassava roots, chips or starch, or sugarcane — can be used as an alternative to ABS plastic filament...
