分区域变参数FDM3D打印设计与试验

Design and Experiment on Partition Definition and Mutative Parameters of FDM 3D Printing

FDM(Fused Deposition Modeling,熔融沉积成型)是目前应用最广的3D打印技术之一。打印时间、表面精度和耗材成本是影响FDM3D打印推广应用的三大难点。作者提出对FDM3D打印的模型进行新的区域划分,且不同区域采用不同层厚和打印速度,在不增加耗材成本和不降低模型表面精度的前提下,明显减少打印时间。作者设计了试验模型,详细研究了分区域变参数FDM3D打印过程,通过实验证明了分区域变参数FDM3D打印的可行性,为后续深入研究提供了重要参考。

FDM （Fused Deposition Modeling） is one of the most widely used 3D printing technologies. Print time, surface precision and material cost are the three big difficulties that affecting the popularization and application of FDM3D printing. A new partition definition was put forward for FDM3D print model, and mutative layer thickness and printing speed were adapted for each partition＇s 3D printing, which remarkable reduced the print time without increasing material cost or reducing model surface precision. An experimental model was designed, and the FDM3D process of the new partition definition and mutative parameters was studied in detail. Experiments were conducted and results proved that the FDM3D printing with new partition definition and mutative parameters was feasible, which provided important reference for subsequent research .
