摘要： Compositions or finishing solutions configured to remove unwanted material, such as uncured resin and ceramic filler, from surfaces of additively manufactured objects are disclosed herein. The finishing solutions may be configured to remove such uncured resin and ceramic filler through submersion of the object in the finishing solution and agitating the submerged object at an ultrasonic frequency, without subjecting the object to any subsequent mechanical acts (such as brushing, sanding, or bead blasting) to remove any remaining uncured resin and/or ceramic filler from the object. In one example, the finishing solution includes a first glycol ether and a second glycol ether and/or a high flash point hydrocarbon, wherein the finishing solution has a flash point of at least 93.3° C. In alternative examples, the finishing solution may also include a third glycol ether, a high flash point alcohol, and/or an acetate of a glycol ether.

摘要： 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.

摘要： 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, one or more nozzles within the chamber, a tank positioned below the nozzles, and a diverter positioned between the nozzles and the tank. The support surface may be configured to support the AM part and may have one or more openings 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 semiatomized spray of the fluid. The diverter comprises an umbrella or a diverter shield and diverts sprayed fluid from directly impacting the fluid being collected in the tank, whereby foaming of the fluid in the tank is reduced.

摘要： Described are finishing solutions for removing support material and finishing 3D-printed objects. The finishing solution may contain a base (e.g., an aqueous base), an optional first caustic agent, an optional second caustic agent, an optional third caustic agent, an optional emulsifier, a polyol, a first antifoaming agent, an optional second antifoaming agent, and water. Also described are methods of using the finishing solution described herein.
