Title
(EN) APPARATUS, SYSTEM AND METHOD OF ADDITIVE MANUFACTURING TO IMPART SPECIFIED CHARACTERISTICS TO THE PRINT MATERIAL AND THE PRINTED OUTPUT
(FR) APPAREIL, SYSTÈME ET PROCÉDÉ DE FABRICATION ADDITIVE POUR CONFÉRER DES CARACTÉRISTIQUES SPÉCIFIÉES AU MATÉRIAU D'IMPRESSION ET AU PRODUIT IMPRIMÉ
Abstract
(EN)
The disclosed exemplary apparatuses, systems and methods provide a three-dimensional molding, produced via a layer-by-layer process in which regions of respective layers of pulverant are selectively melted via introduction of electromagnetic energy. The embodiments comprise layers of the pulverant comprising at least thermoplastic polyurethane polymer (TPU) that provide a hardness of 40 - 100 Shore A; a tensile strength of 5 to 50 MPa; an elongation at break of 50 to 700%; a compression set of 5 to 60 %; and a density of 0.9 to 1.8 g/cc.
(FR)
Les appareils, systèmes et procédés donnés à titre d'exemple fournissent un moulage tridimensionnel, produit par l'intermédiaire d'un processus couche par couche selon lequel des régions de couches respectives de matériau pulvérulent sont fondues sélectivement par l'intermédiaire d'une introduction d'énergie électromagnétique. Les modes de réalisation comprennent des couches du matériau pulvérulent comprenant au moins un polymère de polyuréthane thermoplastique (TPU) qui fournit une dureté de 40 à 100 Shore A ; une résistance à la traction de 5 à 50 MPa ; un allongement à la rupture de 50 à 700 % ; un ensemble de compression de 5 à 60 % ; et une masse volumique de 0,9 à 1,8 g/cc.
