摘要
激光选区熔化工艺中,合理的支撑结构对于保证零件成形质量有重要作用,其中薄壁支撑是应用最广的一种支撑结构类型。通过分析薄壁支撑结构的工艺要素,简述基于STL模型的薄壁网格支撑结构自动生成流程,提出了分区的薄壁支撑结构自动生成方法,并开发了相应的软件工具。通过生成多个零件的薄壁分区支撑结构,验证了该方法的可行性。
The reasonable supporting structure plays an important role in ensuring the forming quality of the parts in the selective laser melting process.The Thin-walled support is the most widely used type of the supporting structure.By analyzing the process elements of thin-walled support structure and describing the automatic generation process of thinwalled grid support structure based on STL model,the algorithm of automatic generation of thin-walled support structure of separate area is proposed and the corresponding software functions are developed.The feasibility of the implementation method is verified by generating the thin-walled partition support structures for parts.
