Abstract

Systems and methods are provided for achieving more accurate 3D printed parts than printed parts achieved by conventional means. The disclosed systems and methods reduce the need for tolerance fitting when designing 3D objects and manufacturing with stereolithographic 3D printers. Embodiments of the present disclosure enable fitted assemblies to be manufactured and produce accurate standoffs where size constraints are critical. Embodiments of the present disclosure realize these solutions without requiring modifications to the printer or the printer software.
