摘要
3D打印技术多以单材均质为基础,开展金属、塑料等零部件的快速成型制造。在此基础上,发展了激光近净成形、熔融挤出成型、选择性激光烧结(熔化)、立体光刻等3D打印工艺和装备。论文以流体挤出成型和激光烧结为基础,结合工业机械手6自由度的空间特性,初步搭建了机械臂3D打印系统;对该系统构成做出了简要介绍,分析了该系统的数据链与数据模型的坐标转换;对电气性能器件常用材料导线银、树脂基复合材料、硅酮橡胶、碳化硅陶瓷等的成型工艺进行了初步探索,为下一步制造出具备电气性能的功能结构化器件与进行曲面3D打印的研究打下基础。
Majority of the 3D printing technologies are developed on the basis of mono and homogeneous material （plastics, metals） processing method. The correlative system and commercial equipment are found as LENS,FDM,SLS,SLM, and SLA. The development of multi-material multi -technology additive manufacturing system is an important guarantee for rapid protatyping of functional devices. Given the importance of robotic manipulator of 6 DOF spatial motion, a robotic 3D printing system is built in this study, employing fluid extrusion method together with laser sintering The communication interface, data link and data model are analyzed. Furthermore, conductive A g circuit,3D cellular structures of silicone rubber, carbon fiber enforced composites and silicon carbide ceramics, are manufactured using the robotic 3D printing technologies, and the related results are reported.
