Single-cylinder type desktop type laser area selecting fusion forming device and control method

Abstract

The invention discloses a single-cylinder type desktop type laser area selecting fusion forming device and a control method. A printed component and a base plate are directly ejected in a powder taking mechanism through a forming cylinder, the powder taking mechanism can be integrally taken out, metal powder cannot be left in the corner of the forming cylinder, the component is taken out by dismounting the powder taking mechanism, and therefore the residual metal powder can be collected, material waste in the forming process is reduced, and the production cost is greatly saved. The size and the overall weight of the single-cylinder type desktop type laser area selecting fusion forming device are greatly reduced compared with those of a current device, the height is only 1 / 3 of the height of a conventional device, the width is only 1 / 2 of the width of the conventional device, the overall weight of the device is about 1 / 8-1 / 6 of the weight of the conventional device, the whole forming device can be placed on a desktop to be used, the manufacturing cost of the device is greatly reduced compared with that of the conventional device, and the small fine metal component manufacturing and small and medium-sized enterprise bearing capability can be achieved; the whole forming device is reasonable in structural layout, operation is easy and convenient, and the development of the metal 3D printing technology can be promoted conveniently.

Description

technical field [0001] The invention relates to the field of 3D metal printing equipment, in particular to a single-cylinder desktop type laser selective melting forming equipment and a control method. Background technique [0002] Selective Laser Melting (SLM) technology, also known as "metal 3D printing technology", is the cutting-edge technology of additive manufacturing. It uses a focused laser beam with a diameter of 30-50 microns to melt metal or alloy powder layer by layer. Form a metallurgically bonded and compact entity, so as to obtain metal functional parts with almost any shape and complete metallurgical bonding. [0003] SLM equipment is mainly composed of laser, optical path system, sealed forming chamber, mechanical transmission system, control system and other parts. The process flow is as follows: firstly, the 3D CAD model is sliced ​​discretely and the scanning path is planned to obtain the slice profile information that can control the laser beam scanning...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a single-cylinder table-top type laser selective melting forming equipment and control method, aiming to solve the problem that the general size of the existing SLM equipment is not suitable for fine precious metals, the equipment is expensive, and the structural design does not consider the precious metals. The recycling and cleaning of metal powders cause material waste and increase production costs
