Title (EN) METHOD FOR MANUFACTURING A THREE-DIMENSIONAL OBJECT
(FR) PROCÉDÉ DE FABRICATION D’UN OBJET TRIDIMENSIONNEL
Abstract:
(EN) The invention pertains to a method for manufacturing a three-dimensional object with an additive manufacturing system, such as an extrusion-based additive manufacturing system, a selective laser sintering system, and/or an electrophotography-based additive manufacturing system, comprising providing a support material comprising more than 50 % wt. of a semi-crystalline polyamide [polyamide (A)] having a melting point, as determined according to ASTM D3418, of at least 250°C and possessing a water absorption at saturation, by immersion in water at 23°C, of at least 2 % wt.
(FR) L'invention concerne un procédé de fabrication d'un objet tridimensionnel au moyen d’un système de fabrication additive, tel qu'un système de fabrication additive basé sur l'extrusion, un système de frittage laser sélectif, et/ou un système de fabrication additive basé sur l'électrophotographie, comprenant la fourniture d'un matériau support comprenant plus de 50 % en poids d'un polyamide semi-cristallin [polyamide (A)] présentant un point de fusion, tel que déterminé selon la norme ASTM D3418, d'au moins 250 °C et possédant une absorption d'eau à saturation, par immersion dans de l'eau à 23 °C, d'au moins 2 % en poids.
