[2] Digitally fabricated objects are created with a variety of CAD software packages, using both 2D vector drawing, and 3D modeling.
The G-codes drive a machine tool, a powered mechanical device typically used to fabricate components.
CNC machines are specifically successful in milling materials such as plywood, plastics, foam board, and metal at a fast speed.
[6] Objects cut out of materials can be used in the fabrication of physical models, which will only require the assembly of the flat parts.
Stereolithography uses a high intensity light projector, usually using DLP technology, with a photosensitive polymer resin.
It will project the profile of an object to build a single layer, curing the resin into a solid shape.
Common materials are plaster of paris, clay, powdered sugar, wood-filler bonding putty, and flour, which are typically cured with water, alcohol, vinegar, or some combination thereof.
