Embodiment Construction

[0023] The technical idea of ​​realizing the above-mentioned invention is that, according to the basic principle of rapid prototyping manufacturing technology, that is, the principle of layered manufacturing, the layered section data of the three-dimensional model processed by the professional layered software of the computer drives the precision printing head, according to the cross-sectional shape of the model Spray liquids of various colors on the pre-laid powder layer, so that part of the powder is bonded together to form a colorful cross-sectional figure. After one layer of powder is formed, another layer of powder is laid to bond the next layer of powder. The unbonded powder plays a supporting role in the molding of the part. This cycle continues until the workpiece is completed, and then the colored shaped parts are obtained through post-processing.

Abstract

The present invention discloses a kind of 3D color printing and quick forming device and method. The 3D color printing and quick forming device includes an X-Y scanning platform and a Z motion mechanism. The X-Y scanning platform is provided with powder providing tank, forming tank, powder roller and printing head; and the Z motion mechanism includes pistons inside the powder providing tank and the forming tank. The quick forming process is one combination of quick forming technology and color printing technology and includes the following steps: jetting pigment of different colors with the precise printing head to the compact powder material inside the forming tank to form color cross section pattern, curing the powder material, lowering the powder material inside the forming tank by the height of one layer thickness while raising the powder material inside the powder providing tank by one layer thickness, forming one new powder material layer, and so on until forming the cured body.

Description

technical field [0001] The invention belongs to the advanced manufacturing technology field of the manufacturing industry, and in particular relates to a novel three-dimensional color printing rapid prototyping device and method. Background technique [0002] Rapid prototyping technology is an advanced manufacturing technology developed in the 1980s. It integrates the achievements of modern numerical control technology, CAD / CAM technology, laser technology and new material science, and quickly turns abstract CAD design data into real objects. And no mold and tooling are needed. [0003] The more mature rapid prototyping methods include SL-Stereolithography, LOM-Laminated Object Manufacturing (LOM-Laminated Object Manufacturing), selective laser sintering SLS (SLS-Selective Laser Sintering), fused deposition FDM (FDM-Fused DepositionModeling) and 3D printing 3DP (Three Dimension Print). [0004] At present, there are mainly two types of 3D printing ...
