3D PRINTING DEVICE FOR MULTIPLE MATERIALS AND 3D PRINTING METHOD FOR MULTIPLE MATERIALS

摘要

The present invention relates to a 3D printing device for multiple materials comprising: a material transfer unit (1100) comprising at least two lines (1100a, 1100b); a material supply unit (1200) to supply at least one type of printing material on each line of the material transfer unit; a thickness control unit (1300) to control a thickness of a material supplied by the material supply unit; a 3D printing module (1400) to solidify the material controlled with the thickness by the thickness control unit to a predefined shape to solidify the material on one line and to move to the other line so as to solidify the material on the other line; a material processing module (1500) to perform washing or drying for the material solidified by the 3D printing module; and a collecting module (1600) to collect the printing material unused during the printing.
