Abstract

The invention discloses an annular four-cylinder efficient rapid prototyping device and method. The device comprises two laser sources, two prototyping cylinders, two transition cylinders, a powder laying roller, a rotating base, a cross partition board, two prototyping cylinder lifting supporting plates and two transition cylinder lifting supporting plates; the two prototyping cylinders and the two transition cylinders jointly form an annular four-cylinder body, the four cylinders are the same in size, the four cylinders are isolated to be independent through the cross partition board, the prototyping cylinders are used for loading prototyping parts and the powder supporting material, the prototyping cylinder lifting supporting plates are arranged inside, a prototyping part does the lifting motion, the laser sources are arranged over the two prototyping cylinders, the powder in the prototyping cylinders is scanned, irradiated and sintered, the two transition cylinders are used for recycling and supplying powder materials at the same time, the rotating base is located on the crossing position of the cross partition board, the powder laying roller mounted on the rotating base is driven to rotate, and the powder material is supplemented and recycled. The machining efficiency can be improved, the manual labor amount is reduced, and automatic manufacturing is achieved.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping manufacturing equipment, in particular to an annular four-cylinder high-efficiency rapid prototyping device and method. Background technique [0002] Rapid prototyping technology (also known as rapid prototyping manufacturing technology, Rapid Prototyping Manufacturing, referred to as RPM), also known as 3D printing. According to the three-dimensional model data of the object, the technology manufactures the entity in a layer-by-layer manner through the forming equipment, which can overcome the special structural obstacles that cannot be realized by traditional mechanical processing. Simplified production of arbitrary complex structural components can be realized. Existing 3D printing technologies are mainly divided into: fused deposition modeling (FDM), selective laser sintering (SLS), stereolithography (SLA), digital light processing (DLP) and so on. [0003] For selective laser sint...
