Problems solved by technology

After one layer of cross-section is sintered, the workbench will be lowered by one layer thickness. At this time, the pressure roller will evenly spread a layer of powder on it and start the sintering of a new layer of cross-section. After repeated operations, the workpiece will be completely formed, but due to the frame Due to the limitation of the body, too much material will be used each time, which will lead to contamination of unused filled materials during the printing process. In order to save materials

Abstract

The invention relates to a 3D printing base, more specifically a multifunctional SLS3D printing variable diameter base, which can not only flatten and compact the material through the flattening wheel, but also control the lifting of the base through hydraulic pressure, and control the area of ​​the base The size of the baffle can also be controlled by the motor to adapt to the change of the base. The sliding rod is fixed on the upper part of the bracket; there are two brackets, and the brackets are fixed on both sides of the base; there are two baffles, and the baffles are fixed on the push plate; the hydraulic control base is fixed inside the base; The upper part of the sliding rod; there are four pushing plates, two of which are fixed with the baffle; the base is square.

Description

technical field [0001] The invention relates to a 3D printing base, more specifically a multifunctional SLS 3D printing variable diameter base. Background technique [0002] In the SLS selective laser sintering process, a layer of powder is first spread on the upper surface of the formed workpiece by pressing rollers, and the numerical control system controls the laser beam to scan and irradiate the powder layer according to the cross-sectional profile of the layer to raise the temperature of the powder to melting points, thereby sintering and bonding to the underlying formed part. After one layer of cross-section is sintered, the workbench will be lowered by one layer thickness. At this time, the pressure roller will evenly spread a layer of powder on it and start the sintering of a new layer of cross-section. After repeated operations, the workpiece will be completely formed, but due to the frame Due to the limitation of the body, too much material will be used each time,...
