Title (EN) FORMING THREE-DIMENSIONAL (3D) PARTS
(FR) FORMATION DE PIÈCES EN TROIS DIMENSIONS (3D)
Abstract:
(EN) In an example implementation, a method of forming a three-dimensional (3D) part includes spreading a layer of build material over a print bed, and heating the layer of build material during each of multiple consecutive carriage passes over the print bed to maintain printed portions of the build material above a melting temperature for the duration of the consecutive carriage passes.
(FR) Dans un exemple de mode de réalisation, la présente invention concerne un procédé de formation d'une pièce tridimensionnelle (3D) qui consiste à étaler une couche de matériau de construction sur un lit d'impression et à chauffer la couche de matériau de construction pendant chacun de plusieurs passages consécutifs de chariot sur le lit d'impression pour maintenir des parties imprimées du matériau de construction au-dessus d'une température de fusion pendant la durée des passages consécutifs de chariot.
