Patent number: 11859108Abstract: Described are finishing mediums for removing support material and/or for surface finishing of objects made via additive manufacturing techniques. The finishing medium is an aqueous solution containing 1-20% by weight a polyol, 1-20% by weight an anti-corrosion agent, 0.001-10% by weight a hydrotrope. The finishing medium may optionally suspend media particles, thereby forming a finishing suspension. Also described are methods of using the finishing media and finishing suspensions described herein.Type: GrantFiled: July 1, 2022Date of Patent: January 2, 2024Assignee: PostProcess Technologies, Inc.Inventors: Daniel Joshua Hutchinson, Marc Farfaglia, Cassidy Grant

Publication number: 20230241683Abstract: A surface finishing apparatus and method for smoothing and coloring parts made by additive-manufacturing technologies is disclosed. The surface finishing apparatus includes a tank or chamber into which a part is placed. A colorant is added. The part is both colored and smoothed until the part is at a desired smoothness and color. The part may be smoothed by different suitable smoothing technologies, including abrading with solid media, spraying with a liquid fluid, spraying with solid particles entrained in a liquid fluid, or submersing in a liquid vortex. Also disclosed is a composition for a colorant for a finishing process that smooths a surface of an additively manufactured part while coloring the additively manufactured part.Type: ApplicationFiled: October 26, 2020Publication date: August 3, 2023Applicant: PostProcess Technologies, Inc.Inventors: Daniel Joshua Hutchinson, Matthew J. Noble, Marc Farfaglia, Owen Wegman

Publication number: 20230158567Abstract: An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part (the “AM part”) is disclosed. The apparatus may include a chamber, a support surface within the chamber, and one or more nozzles within the chamber. The nozzles may be the same size or different sizes. The support surface may be configured to support the AM part. The support surface may have one or more openings sized and configured to allow the fluid to pass through the opening(s). The nozzles may be configured to spray a fluid at the AM part, and the spray may be an atomized or semi-atomized spray of the fluid. For removing support material from parts with internal spaces, such as cavities or passages, the apparatus can include a nozzle at the end of an adjustable flexible hose member that can be adjusted to spray into an internal space of the part. Alternatively, for removing unwanted support material from multiple parts with internal spaces, the apparatus may include a submersion tank.Type: ApplicationFiled: November 17, 2022Publication date: May 25, 2023Applicant: PostProcess Technologies, Inc.Inventors: Nicholas Cudzilo, Jon Strible, Daniel J.

Publication number: 20220363002Abstract: An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part is disclosed. The apparatus may include a chamber, a support surface within the chamber, one or more nozzles within the chamber, a tank positioned below the nozzles, and a vision system. The vision system includes one or more cameras and other imagery obtaining sensors located in the chamber. The cameras and sensors obtain imagery of the additively manufactured part as it is being sprayed to finish the part. The imagery is displayed on a display panel located outside the apparatus or stored for later playback.Type: ApplicationFiled: July 27, 2022Publication date: November 17, 2022Applicant: PostProcess Technologies, Inc.Inventors: Daniel Joshua Hutchinson, Owen Wegman, Gary Burch, Marc Farfaglia

Publication number: 20190204234Abstract: A method and an apparatus for detecting whether a liquid comprising one or more improper substances or an improper amount of one or more substances has been added to a system for removing support material from and/or smoothing a surface of a part made by additive manufacturing. The apparatus may have a sample material that is altered if the improper fluid contacts the sample material. The alteration may be due to characteristics of the improper fluid at the time the improper fluid is added to the system. In some embodiments of the invention, the sample material is capable of chemically reacting with the improper fluid. The apparatus also includes a sensor capable of detecting whether the sample material has been altered.Type: ApplicationFiled: December 26, 2018Publication date: July 4, 2019Applicant: PostProcess Technologies, Inc.Inventors: Daniel Joshua Hutchinson, Marc Farfaglia, Cassidy Grant
