【摘要】：虽然FDM技术在3D打印机应用很广泛,但是由于其本质的问题会影响挤出机构过热而导致打印出的成品表面粗糙甚至精度出错。为了解决此问题,研究一般的挤出机构的构造并在此基础上设计一种3种挤出机构联合使用的三喷嘴挤出机构。通过添加新的材料到挤出机构中缓解流体对通道内壁的粘度以及对有变相引起的局部过热问题,优化了3种不同挤出机构联合排列使用的效果。通过实验仿真得到了设计的挤出机构表现优秀并且能够满足实际需求。
[Abstract]:Although the FDM technology is widely used in 3D printers, the surface roughness or even the error of the finished product can be caused by the overheating of extrusion mechanism due to its essential problems. In order to solve this problem. This paper studies the structure of general extrusion mechanism and designs a three-nozzle extrusion mechanism which is used by three kinds of extrusion mechanism. By adding new materials to the extrusion mechanism, the viscosity of the fluid to the inner wall of the channel and the viscosity of the inner wall of the channel are reduced by adding new materials to the extrusion mechanism. There is a problem of local overheating caused by disguise. The combined arrangement of three different extrusion mechanisms is optimized and the results of experimental simulation show that the extruded mechanism has excellent performance and can meet the actual needs.
