Title
(EN) POLYCARBONATE COMPOSITION AND ASSOCIATED ARTICLE AND METHOD OF ADDITIVE MANUFACTURING
(FR) COMPOSITION DE POLYCARBONATE ET ARTICLE ASSOCIÉ ET PROCÉDÉ DE FABRICATION ADDITIVE
Abstract
(EN)
A composition includes specific amounts of a reinforcing filler and a copolycarbonate containing bisphenol A carbonate units and second carbonate units of the formula wherein Ra, Rb, R3, R4, j, p, and q are defined herein. The composition is useful for fabricating articles that exhibit a desirable balance of heat resistance, printability in large format additive manufacturing, and good surface appearance in printed parts. Also described is a method of additive manufacturing utilizing the composition.
(FR)
Composition comprenant des quantités spécifiques d'une charge de renforcement et d'un copolycarbonate contenant des unités carbonate de bisphénol A et des secondes unités carbonate de la formule ci-jointe, dans laquelle Ra, Rb, R3, R4, j, p et q sont tels que définis dans la description. La composition est utile pour fabriquer des articles qui présentent un équilibre souhaitable entre résistance à la chaleur, imprimabilité par fabrication additive en grand format et bon aspect de surface dans les parties imprimées. L'invention concerne également un procédé de fabrication additive utilisant la composition.
