The Architecture Department's Rapid Prototyping Lab provides equipment and software that students and faculty can use to fabricate physical objects from CAD models. RPL facilities include two ULS laser cutters, a ZCorp 3D printer which creates three-dimensional models from CAD designs, and a CNC router which carves wood or foam in three dimensions under computer control. Laser cutters are available for use by students 24 hours/day following a mandatory safety training session. Students pay a fee for using the ZCorp printer equal to the cost of the materials used.
