Description
Technical field
The present invention relates to material increasing field, and in particular to a kind of fractional scanning path generating method of control increasing material manufacturing stress deformation.
Background technology
Increasing material manufacturing is a kind of rapid shaping technique, after the three-dimensional modeling data of Computer Design first is divided into synusia model data, mathematical model is manufactured into the process of 3D solid object by way of successively increasing material.3D printings have the advantages that low cost, the course of work be pollution-free, shaping speed is fast.Innovation of the technology to core industries such as Aero-Space, automobile, medical treatment and consumption electronic products has huge impetus.From the point of view of world wide, by development for many years, 3D printings have formed fairly perfect technical system, and range of application is constantly expanded, and industrial chain is preliminarily formed, and market scale realizes rapid growth.
SLS is selective laser sintering, and its operation principle 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 forming an aspect of part.After sintering completes one layer, 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, and is layering, until 3 d part shaping.
During existing 3D printing part, by the part after laser sintered, because the inside parts stress after laser beam flying cannot disperse, part can occur stress deformation, influence the quality of forming parts.
The content of the invention
In order to solve the above technical problems, we have proposed a kind of fractional scanning path generating method of control increasing material manufacturing stress deformation, its purpose is to the formed precision for reducing stress deformation, improving part.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of fractional scanning path generating method of control increasing material manufacturing stress deformation, it comprises the following steps：
S1：3D physical models according to printing part are cut into slices, and obtain the panel data of individual layer；
S2：According to the panel data of individual layer, current plane data are obtained；
S3：According to current plane data, the scanning path of generation fixed angle or arbitrary angle, and the scanning pattern is divided into some sections, carry out path scanning to each section respectively；
S4：According to next layer plane data of current plane data in S2, S3, another scanning pattern of generation fixed angle or arbitrary angle, and another scanning pattern is divided into some sections, carry out path scanning to each section respectively；
S5：S4 is repeated, the scanning pattern until completing the whole model of acquisition.
