Title (EN) METHOD FOR PRODUCING A POLYCARBONATE ARTICLE
(FR) MÉTHODE DE FABRICATION D'UN ARTICLE EN POLYCARBONATE
Abstract:
(EN) A method for producing a polycarbonate article comprises printing a droplet onto a target location in a build area to obtain a printed droplet, wherein the droplet comprises a precursor solution comprising a precursor composition, a catalyst, and a solvent; removing at least a portion of the solvent from the printed droplet to obtain a bead comprising a precursor precipitate, wherein the precursor precipitate comprises the precursor composition and the catalyst; repeating the printing step and the removing step adjacent to or on the bead to obtain a plurality of adjacent beads comprising precursor precipitates; and polymerizing the precursor precipitates to obtain the polycarbonate article.
(FR) Une méthode de production d'un article en polycarbonate comprend les étapes suivantes : imprimer une gouttelette sur un emplacement cible dans une zone de construction pour obtenir une gouttelette imprimée, la gouttelette comprenant une solution précurseur comprenant une composition précurseur, un catalyseur et un solvant; éliminer au moins une partie du solvant de la gouttelette imprimée pour obtenir une bille comprenant un précipité précurseur, le précipité précurseur comprenant la composition précurseur et le catalyseur; répéter l'étape d'impression et l'étape d'élimination de façon adjacente à ou sur la bille pour obtenir une pluralité de billes adjacentes comprenant des précipités précurseurs; et polymériser les précipités précurseurs pour obtenir l'article en polycarbonate.
