3D Printing Methods

3D Printing Methods

3D printers print layer on top of layer,
slowly building a three-dimensional
object. A plethora of materials and
methods are used to build these layers.

The Stratasys Dimension is a commercial 3D
printer that uses ABS plastic. The ABS filament
comes in a self-loading cartridge, and is fed into
a heater block by two drive wheels. In the heater
block, the ABS is heated to a semiliquid state and
extruded through the tip, with layers as thin as 0.01".
