Description
Technical field
The present invention relates to a kind of power spreading devices, and compound paving is scraped suitable for selective laser sintering more particularly to a kind of
Powder device.
Background technology
Selective laser sintering, abbreviation SLS are to make the energy using infrared laser, and the Modeling Material used is mostly powder
Material.During processing, powder is preheating to the temperature of slightly less than its fusing point first, then spreads powder under the action of rod is struck off
Flat, laser beam is selectively sintered under the control of the computer according to layering cross section information, is carried out again after the completion of one layer next
Layer sintering.This method is not limited by 3 d part complexity, and part can be produced without any moulds of industrial equipment.
But in selective laser sintering manufacturing process, to be sintered out a good part, then powder needs uniform
Shaping area is densely spread into be sintered.Traditional sintering process is to use press-powder roller compaction powder again after completing powder in advance
Then end carries out laser sintered, tedious process inefficiency again.It is difficult not only thickness again because due to powder particle very light weight
Powder is uniformly laid in part surface layer, and since powder particle is atomic small, so in press-powder roller during rolling
Very small with the frictional force of powder, powder bed is difficult to that the press-powder roller is driven to carry out rolling compacting, is easy to cause in compacted powder
The density of the powder of same layer is inconsistent in the process, and product qualification rate is caused to decline, and powder particle is easy during powdering
It floats everywhere and pollutes working environment etc..
In conclusion present powdering equipment powdering efficiency is low, powder flatness and compactness are poor, and can also pollute work
Make environment.
