Abstract

The invention discloses a 3D printing machine which comprises a printing chamber. A printing assembly and a bearing platform are arranged in the printing chamber. The printing assembly is arranged above the bearing platform. The printing assembly comprises a printing support, a printing head assembly and a curing lamp assembly, wherein the printing head assembly and the curing lamp assembly are connected to the printing support. The printing support moves in the printing direction. In the printing direction, the printing head assembly is located in front of the curing lamp assembly. The printing head assembly comprises a main printing head body of a printing model body and an auxiliary printing head body of a printing supporting material. The model main material is photosensitive resin. The printing temperature in the printing chamber is lower than the solidification temperature of the supporting material. The supporting material is solidified at the printing temperature. The invention further discloses a 3D printing method. By means of the 3D printing machine and the 3D printing method, the supporting material is removed easily.

Description

technical field

[0001] The invention relates to the field of 3D printing, in particular to a 3D printer and a 3D printing method. Background technique

[0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital files, using powder or curable materials, and manufacturing products by layer-by-layer printing. It is in sharp contrast to the subtractive manufacturing technology used in traditional manufacturing. In contrast, 3D printing is an additive manufacturing technology that forms the final product by superimposing layers of materials.

[0003] SLA printer (using stereolithography, SLA) is one of the earliest commercial 3D printers. This type of printer uses UV-cured photosensitive resin to form a printing layer. After printing a layer, the supporting platform moves downward (or upward) A certain distance allows the photosensitive resin layer to cover the previous layer of printing surface again, and then continue to cure. The photo...
