Title (EN) THREE-DIMENSIONAL PRINTING
(FR) IMPRESSION TRIDIMENSIONNELLE
Abstract:
(EN) An example of a three-dimensional (3D) printing composition includes a build material composition and a fusing agent to be applied to at least a portion of the build material composition during 3D printing. The build material composition includes one of: (i) a thermoplastic elastomer having a flow parameter characterized by a consolidation resistance value ranging from about 8 to about 30, and a tap density characterized by an n1/2 value ranging from 5 taps to 30 taps; or (ii) a polyamide-like material having a flow parameter characterized by a consolidation resistance value ranging from about 75 to about 120, and a tap density characterized by an n1/2 value ranging from 5 taps to 30 taps. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the thermoplastic elastomer or the polyamide-like material in the at least the portion.
(FR) Un exemple d'une composition d'impression tridimensionnelle (3D) selon l'invention comprend une composition de matériau de construction et un agent de fusion à appliquer sur au moins une partie de la composition de matériau de construction pendant l'impression 3D. La composition de matériau de construction comprend l'un parmi : (i) un élastomère thermoplastique présentant un paramètre d'écoulement caractérisé par une valeur de résistance de consolidation allant d'environ 8 à environ 30 et une densité tassée caractérisée par une valeur n1/2 allant de 5 tassements à 30 tassements ; ou (ii) un matériau de type polyamide présentant un paramètre d'écoulement caractérisé par une valeur de résistance de consolidation allant d'environ 75 à environ 120 et une densité tassée caractérisée par une valeur n1/2 allant de 5 tassements à 30 tassements. L'agent de fusion comprend un absorbeur d'énergie pour absorber un rayonnement électromagnétique pour la coalescence de l'élastomère thermoplastique ou du matériau de type polyamide dans ladite au moins une partie.
