Abstract
(EN)
A 3D printing apparatus and method is disclosed. According to an aspect of the present embodiment, a 3D printing apparatus for producing a shape by curing a composition comprises: a first light source for emitting light to the composition so as to cure the composition and form a core part having a predetermined area or volume from the center of the shape; a second light source for emitting light to the composition to cure the composition and form a shell part having a remaining area or volume other than the predetermined area or volume in the area or volume of the shape; and a control unit for controlling operations of the first light source and the second light source.

Cette invention concerne un appareil et un procédé d'impression 3D. Selon un aspect d'un mode de réalisation de l'invention, un appareil d'impression 3D pour produire une forme par durcissement d'une composition comprend : une première source de lumière pour émettre de la lumière sur la composition de façon à faire durcir la composition et former une partie noyau ayant une superficie ou un volume prédéfini à partir du centre de la forme ; une seconde source de lumière pour émettre de la lumière vers la composition pour faire durcir la composition et former une partie coque ayant une superficie ou un volume restant autre que la superficie ou le volume prédéfini dans la superficie ou le volume de la forme ; et une unité de commande pour commander les opérations de la première source de lumière et de la seconde source de lumière.
