Description

A kind of powder of 3D printer puts down device

Technical field

The present invention relates to 3D printing technique field, more particularly to a kind of powder of 3D printer puts down device.

Background technology

3D printing technique, also referred to as increases material manufacturing technology, by automatic numerical control successively buildup of material process realize The printing of threedimensional model.For traditional process technology, 3D printing technique need not separately make mould, directly process Go out finished product.And the special construction obstacle that tradition machinery processing can be overcome not realize, it is possible to achieve arbitrarily complicated structural portion The simplification production of part, can automatically, it is direct, will be accurately converted into by design philosophy from CAD model with certain function Model or device.

At present, 3D printing technique can be divided into according to forming principle：Selective laser sintering forming technique SLS, selective laser Melt molding technology SLM, precoated sand forming technique FMS.SLS is selective laser sintering forming technique, is first by CAD 3D mould Type is converted into STS files, is cut into slices according to certain thickness, the cross section profile cut into slices.Then laser beam is controlled to mould The powder of type solid section is scanned, and is made powder particles fuse and adhered to one another, is progressively obtained the profile of this layer.Complete one layer After scanning, workbench declines layer cross section height, then carries out next layer of powdering and sintering, ultimately forms threedimensional model.SLM is Selective laser melt molding technology is a kind of mathematical model based on three-dimensional body, is successively accumulated using powdery metal, is formed The 3 d part of arbitrarily complicated structure.Precoated sand forming technique is that FMS is as raw materials for production, according to computer using precoated sand Cut into slices file, control laser beam the precoated sand of model solid section is scanned, make precoated sand melt and it is adhered to one another, progressively Obtain the profile of this layer.After completing one layer of scanning, workbench declines layer cross section height, then carries out next layer of powdering and burning Knot, ultimately forms threedimensional model.

Powdering operation principle is to drive power spreading device to move by screw mandrel slide unit in existing 3D printing technique, such Move mode it is possible that power spreading device to the inaccuracy of powdering position, what is used in also existing 3D printing technique puts down Device is to be unable to adjustment position, runs into external force collision and the deviation for putting down setting position occurs, have a strong impact on powdering quality, together When can also increase production cost.
