Abstract

The present invention provides a laser 3D printing system and its printing method. The printing system includes: a laser, a scanning lens connected to the laser, an optical system, a vacuum cavity, a gas cylinder located outside the vacuum cavity, and a gas cylinder connected to the gas cylinder. And extend into the air pipe of the vacuum cavity, the working cavity and the radiant heat source positioned in the vacuum cavity, the powder spreading roller positioned on the working cavity, wherein the working cavity is provided with a raw material cavity, a molding cavity, and waste cavity. The present invention uses Teflon powder as consumables for 3D printing. By adopting laser selective sintering technology, the environment and process of molding are controlled at the same time. Efforts have been made to improve the detection and control of the already formed environment, and realize the rapid prototyping process that can use Teflon material series.

Description

technical field [0001] The invention belongs to the technical field of Teflon processing, and in particular relates to a laser 3D printing system and a printing method thereof. Background technique [0002] The existing rapid prototyping technology (3D printing) using laser selective sintering is becoming more and more mature, and 3D printers suitable for different fields and with different functions have been developed at home and abroad. For the preparation of models by 3D printers, although it has various advantages that traditional processing methods do not have, such as material utilization rate close to 100%, no molding shape restrictions, short design cycle, and low cost. [0003] At present, the 3D printing equipment and products using laser selective sintering technology on the market mainly process metal powder, ABS powder and nylon powder. Formed products are thus limited to those made of metal, nylon and ABS materials. The reasons for the molding materials limi...
