Be connected with part or and substrate connection, after shaping, the powder in grid can not be removed, and cause waste of material, and cost increases
Add, after heat treated, powder fuses into one with lattice support, adds the difficulty of post processing.
Utility model content
For problems of the prior art, the utility model provides a kind of branch for selective laser melting shaping
Support structure, it is simple in structure effective, in process of production, the loss of raw material is reduced, improves printing effect, after reducing
Manage difficulty.
The utility model is to be achieved through the following technical solutions：
A kind of support construction for selective laser melting shaping is arranged in array at grade including several
Support unit；Each support unit includes several support monomers, and support monomer is horizontally arranged hollow tubular structure, with
The length direction of blank pipe be X-direction, several support monomers in the Y direction in Z-direction in array set, adjacent supports unit
Support unit is interconnected to form by blank pipe tube wall, blank pipe forms the lateral powder spout of support unit.
Preferably, the cross section for supporting monomer is in the figure that can gather, support monomer in the Y direction with array in Z-direction
The Mi Pu of the figure is formed afterwards, then forms support unit；The all blank pipes of lateral powder spout in support unit.
Preferably, the cross section for supporting monomer is in the figure that can not be gathered, and support monomer is gone into battle in the Y direction with Z-direction
Form support unit after row, the level that the lateral powder spout in support unit includes being formed between blank pipe and adjacent blank pipe is led to
Road.
Preferably, leakage powder gap is both provided between adjacent supports unit.
Further, the leakage powder gap location between the support unit border of support construction outmost turns sets and connects adjacent branch
Support the support connection sheet of unit.
Further, the horizontally arranged hollow tubular structure is set in fold-line-shaped.
Compared with prior art, the utility model has technique effect beneficial below：
Support construction described in the utility model is changed the form of support by support unit, forms lateral powder spout,
So as to make support powder inside fully erased after forming, enable the powder inside support after forming parts in Re Chu
It is recycled before reason, and improves printing rate, reduce post-processing difficulty.The powder that conventional mesh support inside can not be cleared out is complete
It clears entirely, reduces the powder usage amount of shaping.The lattice support for laterally going out powder sets print speed faster, shortens shaping
Time improves efficiency, reduces cost.
It further, can be to support by the support unit border addition support connection sheet to support construction outmost turns
The grid protocol support reinforcing effect of unit improves the rigidity of integral strength and support.
