An additive manufacturing auxiliary printing lifting platform

Abstract

The invention discloses an auxiliary printing lifting platform for additive manufacturing, which includes a forming platform whose top passes through an empty warehouse, and whose middle part is matched with a transmission device fixed at the bottom of the empty warehouse. The other side of the transmission device is matched with a powder storage platform; 1. The bottom is connected to the bottom plate, and the top plate is provided with a powder funnel and a scraper, and two symmetrical wall supports are provided on both sides of the empty chamber near the end of the top plate. The forming platform and the powder storage platform can move up and down relative to the empty chamber respectively. The lifting platform of the present invention can be integrally built into the metal fused deposition printing equipment, and can be disassembled separately; when one type of metal powder is printed and another metal powder is printed, there is no need to disassemble and clean the metal fused deposition printing equipment as a whole , reinstallation, just take the present invention out of the equipment and clean it, which greatly simplifies the operation process, saves working time and labor costs, and shortens the idling time of the equipment.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an additive manufacturing auxiliary printing lifting platform. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is a method of directly manufacturing three-dimensional physical entities in a layer-by-layer manner based on a computer 3D CAD model. Additive manufacturing technology can quickly and precisely manufacture any complex shape in one device These technologies are aimed at high-end manufacturing fields such as aerospace, weapon manufacturing, automobiles, molds, and biomedicine, directly manufacturing three-dimensional complex structures, and solving the problems that are difficult or even impossible to process and manufacture with traditional manufacturing processes. [0003] In view of the superiority of additive manufacturing itself, various targeted 3D printing technologies have emerged, such as: selective las...

AI Technical Summary

Problems solved by technology

Affected by the cost of equipment, many scientific research institutes currently only have one or two printing equipment, but there are many kinds of metal powders that can be printed for scientific research verification, which leads to printing and verification of another type of workpiece after printing one verification workpiece. When planting metal powder workpieces, it is necessary to disassemble and clean the four parts of the metal fused deposition printing equipment and then reinstall them, which takes too long and leaves equipment resources empty. The increase in cost will have a huge impact on the overall airtightness after the equipment has been disassembled and assembled many times
