摘　　要：针对基于笛卡儿坐标系的熔融沉积成型(fused deposition molding,FDM)3D打印机打印旋转体精度低,且速度慢等问题,设计开发了一种基于柱坐标系的FDM 3D打印机.其成型原理和机械结构都借鉴了传统的FDM 3D打印机,并在此基础上将基于笛卡儿坐标系的运动方式改为基于柱坐标系的运动方式.相较于传统FDM 3D打印机,在使用相同的硬件(包括电机、喷头、打印丝材)配置情况下,该设备打印旋转体模型时可以实现更高的打印精度,在某些情况下可以实现更快的打印速度.Because it is hard to fabricate a rotating body shape model by the traditional fused deposition molding （FDM） equipment, a FDM 3D printer was designed, which moved in a cylindrical coordinate system. The forming principle and mechanical structure of this equipment borrowed from the traditional machine, and the motion based on cartesian coordinate system was changed to the motion based on cylindrical coordinate system. Compared to the traditional FDM printer, it can print more precisely and in some cases have a better speed under the same hardware situation.
