The 3D printer uses a process called fused deposition modeling to construct a solid object from a virtual model. This process involves the controlled deposition of a molten feed stock, typically ABS or PLA plastic, onto a build surface where layer-by-layer the model emerges. Each 3D printer features a series of motors to move the three axis and the extruder, and a controller to move the motors and manage the build process.This guide was first published on Aug 05, 2013.
