Abstract
Washing apparatus and methods used to process additively fabricated (e.g., 3D printed) parts are described herein. The apparatus and methods may be used to wash uncured liquid resin from the parts. In some aspects, a method comprises directing a liquid photopolymer into a container removably attached to a rotating device configured to rotate the container and including one or more inlets and one or more outlets, forming a three-dimensional object using a process including: controlling an optics engine to project a sequence of optical patterns onto the container while rotating it on the rotating device, thereby causing the sequence of optical patterns to irradiate the liquid photopolymer from different angles and curing a portion of the liquid photopolymer; and in response to forming an object in the liquid photopolymer, opening the one or more outlets to drain uncured liquid photopolymer in the container.
