Description

TECHNICAL FIELD

[0002] 3D printing process forming is in units of forming base plate, and only one part can be produced at a time; the size of the base plate is not infinite, but has a fixed size. In the preparation stage before production, the base plate is fixed to the equipment lifting platform by using screws, so the base plate is provided with a sink hole for installing the base plate fixing screw, which leads to the need to avoid the sink during the production planning stage. On the one hand, this ensures that the base plate fixing screw can be normally disassembled when the production conditions are prepared and the production is completed; on the other hand, after the base plate is installed, the powder layer thickness in the sink area is uneven and there are many gaps, so the workpiece forming quality is poor at this place, and therefore this place needs to be avoided during production.

[0003] In actual production application, when batch workpieces are manufactured using the 3D printing process, layout must be considered to reduce the number of printing editions, which can often reduce the consumption of raw materials and auxiliary materials, reduce the overall working hours, and improve the project delivery speed; however, due to the sink area on the current base plate structure, the overall layout area and part of the limit size value are small, which cannot be optimally arranged, which means that multiple processing or even replacement of larger 3D printing equipment is required for operation, affecting the overall production efficiency, and improvement is needed.
