Title (EN) A METHOD FOR PRINTING A 3D PRODUCT AND A 3D PRINTING DEVICE
(FR) PROCÉDÉ D'IMPRESSION D'UN PRODUIT 3D ET DISPOSITIF D'IMPRESSION 3D
Abstract:
(EN) The present disclosure relates to a method for manufacturing of one or more 3D products by additive manufacturing using a layer-by-layer technique using a3D printing device (1). The 3D printing device (1) comprises at least one layer applying unit (3) for depositing a plurality of material layers, a support (4) arranged to receive the material layers, and a layer bonding unit (5) for binding selected portions of the material layers together such that the one or more 3D products are formed. The at least one layer applying unit (3) applying the material layers parallel to the support (4). The method comprising the steps of depositing the material layers forming a bulk material volume (51, 51', 51''). The material layers are applied such that the bulk material volume (51, 51', 51'') comprises a base portion (52) and a top portion (53), whereby the bulk material volume (51, 51', 51'') is formed such that the top portion (53) is smaller than the base portion (52). A 3D printing device is further disclosed.
(FR) La présente invention concerne un procédé de fabrication d'un ou plusieurs produits 3D par fabrication additive en utilisant une technique couche-par-couche en utilisant un dispositif d'impression 3D (1). Le dispositif d'impression 3D (1) comprend au moins une unité d'application de couche (3) pour déposer une pluralité de couches de matériau, un support (4) disposé pour recevoir les couches de matériau, et une unité de liaison de couche (5) pour lier les parties sélectionnées des couches de matériau ensemble de sorte que lesdits produits 3D soient formés. Ladite unité d'application de couche (3) appliquant les couches de matériau parallèles au support (4). Le procédé comprend les étapes de dépôt des couches de matériau formant un volume de matériau en vrac (51, 51', 51''). Les couches de matériau sont appliquées de sorte que le volume de matériau en vrac (51, 51', 51'') comprenne une partie de base (52) et une partie supérieure (53), moyennant quoi le volume de matériau en vrac (51, 51', 51'') est formé de sorte que la partie supérieure (53) est inférieure à la partie de base (52). La présente invention concerne également un dispositif d'impression 3D.
