Abstract

The invention discloses a nanosecond-picosecond-femtosecond laser technology based metal product 3D printing method. The nanosecond-picosecond-femtosecond laser technology based metal product 3D printing method adopts an integrated optical fiber laser device to provide nanosecond laser so as to sinter, melt and cure a metal raw material, meanwhile using picoseconds or femtosecond laser to conduct finish machining on a finish machining region. A real-time monitoring system can adopt multiple macroscopic and microcosmic detection means, and specially the detection means selection desponds on accuracies required by products to be manufactured. The nanosecond-picosecond-femtosecond laser technology based metal product 3D printing method can achieve more accurate size control, printing efficiency is improved, and cleaning, polishing and other working procedures required after 3D printing are omitted.

Description

technical field [0001] The invention belongs to the technical field of jewelry and artwork printing, and specifically relates to a 3D printing method for metal products based on nanosecond-picosecond-femtosecond laser technology. The metal products refer to metal ornaments and metal handicrafts. Background technique [0002] Many 3D printers today are good at making small, high-value things. So the first people to develop the field of digital fabrication were artists, especially those who made jewelry. However, the 3D printing technology currently used is limited in accuracy. Therefore, even if the 3D model is very fine, the finished product is still not accurate enough and the process is rough. Subsequent work requires manual removal of slag, polishing, cleaning, etc., which will affect the accuracy of the finished product. For example, American Pearl, a well-known jeweler, has developed an online jewelry design customization system that combines CAD software with Solidsca...
