背景技术
现有的FDM型3D打印机在打印悬空、跨桥或者与垂直面夹角超过45°的斜面等结构时，由于没有基底材料，必须采用添加支撑的工艺方法来实现，这样不但会延长打印时间、消耗支撑材料，而且在执行清理支撑的后处理工序时，常因工序繁琐、操作不当等问题在模型表面留下瑕疵。
发明内容
为了克服上述现有技术的不足，本发明的目的是提供一种具有移动支架的FDM型3D打印***，可减少支撑的打印时间和清理，降低支撑材料的消耗，对于悬空、跨桥结构，甚至无需支撑而可直接打印，能够有效地提高3D打印效率，降低3D打印成本。

打印平台02上连接有模型11，模型11和第一移动支架07、第二移动支架08、第三移动支架09、第四移动支架10之间，设有打印支撑12。
所述的第一移动支架07包括第一Y向直线电机071，第一Y向直线电机071的动子上安装有第一连接板072，第一连接板072的上端连接有第一伸缩式液压缸073，第一伸缩式液压缸073的活塞杆端头上连接有第一X向直线电机074，第一X向直线电机074的动子上经第一固定板075连接有第一支撑板076，第一支撑板076上设置有第一基板078，并通过第一压板077将第一基板078固定，第一压板077连接在第一支撑板076上，第一基板078上覆盖有第一波纹纸079。
所述的第二移动支架08、第三移动支架09、第四移动支架10结构和第一移动支架07的结构相同。
本发明的有益效果是：
本发明利用控制装置13驱动分布在打印平台2四周的移动支架，适时地移动到需要打印支撑12的悬空、跨桥或者与垂直面夹角超过45°的斜面等模型11结构的下方，可减少支撑的打印时间和后处理时间，降低支撑材料的消耗，对于悬空、跨桥结构，甚至无需支撑而可直接打印，能够有效地提高3D打印效率，降低3D打印成本。
