Abstract

The invention discloses a steel laser 3D printing active face steel-rubber composite powder scraping cutter, which comprises an rubber scraper and an active face steel bar scraper, wherein the activeface steel bar scraper is fixedly connected to the rear side of the rubber scraper. The rubber scraper is a main powder scraping cutter to avoid micro bulges on a printing surface in a laser 3D printing process. The active face steel bar scraper is an auxiliary cutter to plane local ultrahigh bulges printed on each layer and avoid the bulges from continuously deteriorating. The rubber can be usedindependently.

Description

technical field

[0001] The invention belongs to the technical field of 3D printing doctor blades, and in particular relates to a steel laser 3D printing blade surface steel strip rubber strip composite doctor blade. Background technique

[0002] Steel laser 3D printing is powder bed fusion. Using a laser, the powder particles are fused together point by point, and processed layer by layer until the object is complete. Powder bed fusion systems have heat sources and powder distribution control mechanisms.

[0003] During the steel laser 3D printing process, a large number of problems that equipment operators try to avoid may arise, including porosity, residual stress, warping, cracks, localized bulging, etc.

[0004] (1) Common defects of steel laser 3D printing

[0005] 1. Porosity

[0006] During the laser 3D printing process of parts, very small holes inside will form porosity, which can be caused by the steel laser 3D printing process itself or powder. These microvoi...
