Abstract:

A three-dimensional printing system includes a resin vessel, a support plate, a light engine, a build tray, motorized support, and a controller. The resin vessel includes a vessel body defining a central opening and a transparent sheet that closes the central opening. The transparent sheet is at least partially formed from a cast polypropylene (CPP). The support plate is for supporting the resin vessel and includes a rigid transparent central portion for supporting the transparent sheet. The light engine is configured to project pixelated light to a build plane within the resin. The build tray defines a support surface for supporting the three-dimensional article to be at least partially submerged in the resin. The motorized support is configured to align and adjust a vertical position of the build tray. The controller is for controlling the light engine and the motorized support for fabricating the three-dimensional article.
