Problems solved by technology

However, metal 3D printers on the market do not have dedicated equipment for such products
When the existing 3D printing equipment prints these hollow cylindrical large-scale structural parts, it often takes more than ten days or even a month to print a product. The product has gradually released stress during the long-term printing process, resulting in product failure Final deformation out of tolerance

Abstract

The invention relates to special 3D printing equipment for printing a hollow cylindrical component and a printing method thereof. The equipment comprises a printing device and a powder laying device, the printing device comprises a device shell and a printing substrate, and the printing substrate is located in the device shell and moves up and down in the device shell; the powder laying device is hung above the printing device, and the powder laying device comprises a platform whole body, a powder feeding pipeline, a plurality of laser galvanometers and a plurality of scrapers; the plurality of scrapers are rotationally connected with the whole platform; and the distances between the lower end faces of the scrapers and the printing substrate are different. According to the invention, the plurality of rotatable scrapers and the corresponding number of laser galvanometers are adopted, the printing substrate is divided into a plurality of printing areas, partitioned laser and printing are realized, stepped rotary powder spreading is realized by setting the continuous change of the distance between each scraper and the printing substrate, the printing efficiency can be improved by about 16 times, and finally the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a 3D printing special equipment for printing hollow cylindrical components and a printing method thereof. Background technique [0002] At present, the mainstream metal 3D printing technology SLM (selective laser melting technology) is an emerging additive manufacturing technology. The machine operator selects and sinters the powder of the working platform according to the CAD graphic data, and the high-energy focused laser beam makes the powder completely melt and tightly bond. The parts prepared by laser selective melting technology can reach the theoretical density level, which is a rapid prototyping technology with great development prospects, especially in aerospace, mold, oil pipeline and other fields. [0003] At present, in the fields of aerospace, oil pipelines, and gas turbines, there are many hollow cylindrical large-scale structural parts that can be d...
