Description
Technical field
The present invention relates to material increasing field, and in particular to based on increasing material manufacturing can any dip sweeping path generating method.
Background technology
3D printing technique, i.e. increases material manufacturing technology, based on entity mathematical model file, using moulding material, 3D solid is constructed by way of successively printing.For traditional process technology, 3D printing technique need not separately make mould, directly process finished product.And the special construction obstacle that tradition machinery processing can be overcome not realize, the simplification production of arbitrarily complicated structure member can be realized, can automatically, directly, accurately will be by design philosophy from CAD model, model or part with certain function are converted into, relatively broad application is obtained in fields such as building, Aero-Space, machinery, biomedicines at present.
For selective laser sintering, i.e. SLS, its operation principle, which is computer, controls the two-dimensional scan track of laser beam according to the hierarchical model of prototype, and selectively sintering solid dusty material is to form an aspect of part.Sintering is completed after one layer, and working piston declines a thickness, and powdering system spreads new powder again.Control laser beam scans the new layer of sintering again, so moves in circles, is layering, until 3 d part shaping.
At present, the part after laser sintered, because the inside parts stress after laser beam flying cannot disperse, stress deformation can occur for part, influence the quality of forming parts.
The content of the invention
In order to solve the above technical problems, we have proposed based on increasing material manufacturing can any dip sweeping path generating method, the purpose is to overcome the formed precision of the part caused in response to force deformation low, improve the Forming Quality of part.
To reach above-mentioned purpose, technical scheme is as follows：
Based on increasing material manufacturing can any dip sweeping path generating method, it comprises the following steps:
1）Cut into slices according to the 3D physical models of part to be printed, obtain the panel data of all individual layers；
2）To the panel data layered shaping of all individual layers, the panel data of current individual layer is selected, and obtains current layer panel data and next layer plane data；
3）According to current layer panel data, some regions to be scanned are uniformly divided into along fixed angle or arbitrary angle to current layer panel data, several regions to be scanned of current layer are obtained；
4）According to several regions to be scanned of current layer, several scanning patterns of current layer are generated along arbitrary angle or fixed angle；
5）According to next layer plane data of the panel data of current individual layer, several another regions to be scanned are uniformly divided into along another fixed angle or another arbitrary angle to next layer plane data, next layer several regions to be scanned are obtained；
6）According to next layer several regions to be scanned, next layer several scanning patterns are generated along arbitrary angle or fixed angle；
7）Repeat the above steps 3）、4）、5）、6）, the scanning pattern of the panel data until completing whole all individual layers of model.
It is preferred that, the panel data is the panel data of SLC files, CLI files or extended formatting.
By above-mentioned technical proposal, the beneficial effects of the invention are as follows：Based on increasing material manufacturing can any dip sweeping path generating method, enable to inside parts stress to disperse, reduce and shrink, improve the formed precision of part.
