Description
Technical field
The present invention relates to a kind of combined laser selective melting metal 3D printing substrates, belong to increasing material manufacturing and are beaten with metal 3d
Print field.
Background technology
Metal 3D printing is melted using metal powder as raw material, according to the layering of molded part three-dimensional CAD model in selective laser
Slice information, scanning system control laser beam act on the powder in region to be formed, so that powder is melted, be molded after cooling,
One layer is scanned through, workbench declines certain altitude, repaves one layer of powder, is melting, accumulating repeatedly like this, until completing entire zero
The molding of part.
Selective laser fusing metal 3D printing can directly manufacture metal parts, have the advantages that protrusion.But it is printing
When metal parts, prodigious stress is will produce, leads to the part deformation in print procedure, it is therefore desirable to which part is printed upon substrate
On, prevent part deformation.
Although substrate solves the problems, such as part deformation in print procedure, but also bring detrimental effect to forming, first
First, substrate and part connect together, and removes that part can only be machined into or wire cutting mode is detached.But due to
Substrate is larger, this makes troubles to the cutting separation of part, and the part especially printed when drip molding is smaller, on substrate is more
When, this problem becomes apparent from；Secondly, to reduce stress and promoting to combine, the material kind of substrate and the part of printing is usually required that
Class is identical, and the part for printing different materials needs to change the substrate of different materials, and bulk substrate cost made in one piece is very high；Most
Afterwards, a part of substrate must be cut when drip molding and substrate detach so that printing metacoxal plate must all re-work every time, cause
Substrate is more and more thinner, cannot reuse soon, leads to the increase of 3d printing costs, is needed when especially printing some rare precious metals
Use the substrate of rare precious metal, this problem more apparent.In addition, when replacing substrate every time, it is required for taking a significant amount of time to base
Plate carries out leveling, greatly reduces printing effect.

Preferably, the quadrangle of pedestal 1 of the present invention is equipped with countersunk head threaded hole II 13, for pedestal 1 to be fixed on 3d
In the forming platform of printer.
The size of movable block 2 of the present invention, shape, material are not limited, can be according to the size, shape and conjunction of printout
Golden type is selected, and the selection belongs to conventional selection.
Beneficial effects of the present invention：
（1）Part is printed upon on movable block, and movable block is smaller and can readily remove, the convenient separation of part and movable block.
（2）When printing different materials, it is only necessary to movable block is changed, the cost of substrate is reduced without changing pedestal, it can be with
The only single small movable block used cheap material as pedestal, and destroyed when wire cutting separation, rather than it is entire
Substrate.
（3）The pedestal of leveling can be permanently affixed on workbench, and when printing need to only load onto movable block, save substrate
The leveling time is installed, printing effect is improved.
