Abstract

The invention discloses an area adjustable forming platform and method applied to a 3D printer forming cylinder. The forming platform comprises a first platform, a second platform and a third platformwhich are equal in height and unequal in diameter, wherein the second platform and the third platform are of hollow structures; the three platforms centered by the first platform sleeve successivelyaccording to diameters and are in clearance fit, and the three platforms are placed on an adapting plate connected to a lead screw mechanism; and the first platform is fixedly connected to the adapting plate. The volume of the forming cylinder can be variable and the area of the printing platform can be adjusted by switching the cylinder to a working mode combining different platform according tothe sizes and processing number of SLM forming parts, and the volume of the forming cylinder and the size of the printing platform are skillfully variable. The platform and method not only improve theadaptability of the SLM technology in the field of forming individual complex structure metal parts which are different in size and batch, but also improve the forming efficiency of the SLM and lowerthe cost.

Description

technical field [0001] The invention relates to a molding platform of a 3D printer, in particular to an area-adjustable molding platform and method applied to a molding cylinder of a 3D printer. Background technique [0002] Selective Laser Melting (SLM) technology can directly manufacture metal parts with metallurgical bonding, compact structure, high dimensional accuracy and good mechanical properties, and can form small batches, personalized metal parts with complex surfaces and internal structures. Compared with traditional manufacturing methods such as material reduction and casting, SLM is more suitable for the molding of personalized metal parts (such as jewelry) with complex structures. [0003] At present, the mainstream forming range of laser selective melting is between 100-250mm. All single equipment on the market only has one processing range index. If you buy a 250*250mm SLM equipment, it is difficult to form parts with a certain height because of insufficient ...
