摘要
随着3D打印制造技术日渐成熟,以龙门式框架为基础的传统3D打印设备的支撑问题和仅沿单一方向成型的问题逐渐显现,不能最大程度发挥材料性能,直接导致其无法用于主承力件或结构件,仅能作为快速原型示例使用,而不能满足实际力学性能和表面质量的需求。为此,基于EPSON六轴机械臂,设计构建了用于空间曲面3D打印的机电系统及配套路径生成方案,并以几种典型的基本模型为范例进行了实际加工测试。结果表明:所提出的曲面3D打印系统可以根据设计路径完整进行空间3D打印,传统加工过程中必需的额外支撑完全不再需要,大幅节省了后处理所需时间和所需原材料,相比传统方法节省材料90%以上,材料利用率接近100%,得到的模型工件表面质量良好,实验结果符合预期。
With the increasing maturity of 3D printing manufacturing technology,the support problem and the problem of molding only along a single direction of the traditional 3D printing equipment based on the gantry-type frame are gradually emerging,which cannot maximize the performance of the material,and directly leads to the fact that it cannot be used for the main bearing parts or structural parts,and it can only be used as a rapid prototype example,and it cannot meet the needs of the actual mechanical properties and surface quality.For this reason,based on the EPSON six-axis robotic,electromechanical system and supporting path generation program for spatial multi-directional 3D printing are designed and constructed,and practical processing tests are conducted using several typical basic models as examples.The results show that the proposed multidirectional 3D printing system can carry out spatial 3D printing according to the complete design path,the additional support necessary in the traditional processing is no longer needed,which significantly saves the time required for post-processing and the raw materials needed,saving more than 90%of material compared to traditional methods,with material utilization close to 100%,and the surface quality of the modeled workpieces obtained is good,and the experimental results meet the expectations.
