In some embodiments, a method includes using a layer-by-layer build process on a polymeric resin to produce a plurality of aligner molds. The method can include transporting the plurality of aligner molds to a resin removal station. The method can also include applying high pressure air to the plurality of aligner molds to remove residual material from the plurality of aligner molds. The residual material can include excess polymeric resin. The method can further include collecting the excess polymeric resin.Type: GrantFiled: October 13, 2022Date of Patent: August 22, 2023Assignee: Align Technology, Inc.Inventors: Srinivas Kaza, Shiva P.

Publication number: 20230082315Abstract: A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item.Type: ApplicationFiled: October 13, 2022Publication date: March 16, 2023Inventors: Srinivas Kaza, Shiva P.
