摘要
在研究选择性激光烧结工艺(Selective Laser Sintering,简称SLS)成形误差的基础上,分析造成SLS成形件翘曲的原因,构建了一种新的翘曲变形模型。并以此模型作为基础,提出一种新的光栅扫描方式。通过试验验证,此扫描方式可以有效地降低SLS成形件的翘曲变形,提高SLS成形件精度。
Through studying the error of selective laser sintering （ SLS ）, the reason of curl distortion of the SLS part was analyzed, and a new curl distortion model was built. And on the basis of this model, a new raster scanning way was proposed, which can reduce the curl distortion of the SLS part, and improve the accuracy ofSLS prototyping part verified by practice.
