基于FDM技术探究表面浮雕工艺研究
首发时间:2018-06-20
摘要:以FDM技术中常用的基体材料 PLA 作为对象,通过3D打印实验,利用凹凸对比来探究表面雕刻花纹,研究凹凸浮雕差异和缺陷原因。结果表明,大面积花纹设计利用凸面设计更能体现3D美观性,而对于字体和logo等小而复杂的设计可以利用凹面设计来减少打印成型精度误差。同时本实验还通过单因素实验法探究打印参数对浮雕精度的影响,得出浮雕精度随层厚的增加而降低,温度对浮雕精度的影响小于层厚因素,存在最佳温度区间。

Research on Surface Relief Technology Based on FDM
Abstract:Aim at the material PLA which is always used as the basic material in FDM technology, experiment use Convex Contrast to explore the surface engraving patterns, and study the differences and the defect causes of the concave and convex relief.The results show that the large-area pattern design using the convex design can better reflect the 3D aesthetics, while for small and complex designs such as fonts and logos, the concave design can be used to reduce the accuracy of print-forming . At the same time, this experiment also explored the impact of printing parameters on the precision of relief by single factor experiment method. It is concluded that the relief accuracy decreased with the increase of layer thickness, and the effect of temperature on relief accuracy was less than the layer thickness factor, and there was an optimal temperature range.?????
