Title
(EN) FINISHING OF ADDITIVELY MANUFACTURED PARTS WITH SMOOTHING AND COLOR
(FR) FINITION DE PIÈCES DE FABRICATION ADDITIVE AVEC LISSAGE ET COULEUR
Abstract
(EN)
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.
(FR)
L'invention concerne un appareil et un procédé de finition de surface permettant de lisser et de colorer des pièces fabriquées par des technologies de fabrication additive. L'appareil de finition de surface comprend un réservoir ou une chambre dans lequel est placée une pièce. Un colorant est ajouté. La pièce est à la fois colorée et lissée jusqu'à ce que la pièce ait un lissé et une couleur souhaités. La pièce peut être lissée par différentes technologies de lissage appropriées, y compris l'abrasion avec des milieux solides, la pulvérisation avec un fluide liquide, la pulvérisation avec des particules solides entraînées dans un fluide liquide, ou l'immersion dans un vortex liquide. L'invention concerne également une composition d'un colorant servant à un traitement de finition qui lisse une surface d'une pièce de fabrication additive tout en colorant la pièce de fabrication additive.
