Abstract

The invention provides plastic particle laser selecting and melting equipment which comprises a sealing cabin, a powder feeding system, a laser path system and an atmosphere protection system. A forming platform which is placed horizontally is arranged in the sealing cabin, a lifting mechanism is arranged below the forming platform in a contacting manner and driven by a servo motor, and a powder scraping plate is arranged on the upper surface of the forming platform. A retaining plate adjustable in angle is arranged above each nozzle, so that ejection angle of plastic powder can be controlled, and powder spreading efficiency is further improved.

Description

technical field [0001] The invention relates to a plastic 3D printing device, in particular to a plastic particle laser selection and melting device. Background technique [0002] 3D printing technology is considered to vigorously promote the "third industrial revolution" with its characteristics of digitization, personalization and customization. The technology has been successfully applied to mold manufacturing, industrial design, architectural engineering, aerospace and medical industries. [0003] Selective laser melting (SLM) technology is a technology that uses light curing and paper lamination to achieve rapid prototyping. Its working principle is basically the same as that of ordinary printers. The printer is equipped with powdery plastic and other adhesive materials. After connecting with the computer, through the multi-layer printing method, the blueprint on the computer is finally turned into a real thing. [0004] SLM equipment mainly includes laser, optical pat...
