StereoLithogrpahy has become widely used on- campus as a means of rapidly producing plastic parts from CAD databases. Often, these parts are used in sub- sequent operations, one of the most common of which is as a master for making a mold. In such a process, a material lie silicone is poured around the plastic part. Upon hardening, the plastic part is removed and the resulting cavity in the silicone is the cavity into which liquid plastic can be poured to produce multiple copies of the original. Although quicker than conventional pro- totype mold-making operations, this process requires two steps. Further, the mold-making step is considered more of an art than a science. Both of these limitations can be overcome by producing the mold directly using StereoLithography.
