Solidification solid forming (sla), Fused Deposition Modeling (fdm) etc..Slm technology is the most potential skill of 3d printing technique field
One of art.This technology utilizes high energy beam laser direct fusing metal powder, formable high-performance metal part.
The ultimate principle of slm technology is: the three-dimensional data model of drip molding is set up first with 3 d modeling software, with
Using Slice Software, slicing delamination is carried out to three-dimensional data model afterwards, obtain two-dimensional silhouette data and the laser scanning road in each section
Footpath, these data are imported in quickly shaping device, carry out selective laser fusing and shape.During shaping, first by formation cylinder
Substrate leveling, subsequent power spreading device is taped against formed powder on formation cylinder substrate, and laser beam is according to the current cross section profile of product
Data carries out selective melting shaping.After processing current layer, formation cylinder declines the distance of a thickness, and powder cylinder rises a spacing
From, power spreading device completes metal dust on manufactured current layer, and the data that equipment calls in next layer of profile is processed,
So process layer by layer, until whole part completion of processing.
In slm forming process, product is internal easily to produce larger stress, causes product buckling deformation.In order to reduce part
Buckling deformation, generally product is sintered on substrate, so that product is integrally formed with substrate.When shaping beginning, first have to substrate
Carry out leveling, if substrate is uneven, institute's powdering end is uneven, the bond strength of drip molding and substrate will be reduced, affect forming quality.
Substrate leveling at present is mainly artificial to carry out leveling using clearance gauge, and adjustment process is loaded down with trivial details, and precision is low, reduces forming efficiency.Base
After plate leveling, on substrate during powdering, powdering density there is also considerable influence to quality of item, if powdering density is low, it will
Increase product interior porosity, reduce quality of item it is therefore desirable to improve powdering density further, improve quality of item.
