  • Washing apparatus and methods used to process additively fabricated parts
    Patent number: 11987002
    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. The washing apparatus may include two or more containers for storing respective solvents and may be fluidly connected to a vessel in which the additively fabricated parts are placed. One or more pumps and one or more valves may be controlled to introduce a first solvent from one of the containers into the vessel to wash the part in a first wash cycle and then the valve(s) may be re-configured to introduce a second solvent from another container into the vessel to wash the part in a second wash cycle. Advantageously, the parts may remain in the same vessel while being washed with both solvents in succession.
