基于FDM的自适应分层算法的研究
|
摘要
为了兼顾FDM快速成型的成型质量和效率,对基于FDM的自适应分层算法进行了研究。首先对等厚度分层方法进行了分析计算,发现其弊端;其次对CAD模型进行了参数化分析,通过曲率的正负将图形表面分成了正偏差和负偏差两种情况;最后利用ABS丝材和二次开发的CURA软件,分析了不同层厚对熔融沉积快速成型制件成型质量的影响。结果表明,改进的自适应分层算法易于编程,提高了制件的成型质量,且节省了打印时间。
In order to take into account the accuracy and efficiency of FDM rapid prototype,this paper studies adaptive slicing algorithm based on FDM. First, the method of equal thickness stratification is analyzed, and its malpractice is found. Secondly, the parametric analysis of CAD model is carried out. The positive and negative curves are divided into two cases. Finally, the influence of different layer thickness on the forming quality of the melt-formed rapid prototyping parts is analyzed by using ABS wire and secondary development of CURA software. The results show that the improved adaptive hierarchical algorithm is easy to program, the quality of the parts is improved, and the printing time is saved.
