Title (EN) SACRIFICIAL HIGH HEAT SUPPORT MATERIALS FOR ADDITIVE MANUFACTURING PROCESSES
(FR) MATÉRIAUX SACRIFICIELS DE SUPPORT À HAUTE CHALEUR POUR PROCÉDÉS DE FABRICATION ADDITIVE
Abstract:
(EN) Disclosed herein are methods that includes using a water-degradable (e.g., autoclavable) support material together with a high-heat build material (e.g., polyetherimide or PEI). When the support material is autoclaved for a period of time, the support material becomes brittle and then disintegrates into powder and therefore can be removed from the model or build material, leaving behind a part formed from the model material that includes features (e.g., cavities, channels, etc.) formerly occupied by the support material.
(FR) L'invention concerne des procédés qui comprennent l'utilisation d'un matériau de support dégradable dans l'eau (par exemple, autoclavable) conjointement avec un matériau de construction à haute chaleur (par exemple, polyétherimide ou PEI). Lorsque le matériau de support est autoclavé pendant une certaine période de temps, le matériau de support devient cassant puis se désintègre en poudre et peut par conséquent être enlevé du matériau du modèle ou de construction, laissant une partie formée à partir du matériau de modèle qui comprend des caractéristiques (par exemple, des cavités, des canaux, etc.) auparavant occupé par le matériau de support.
