摘 要: 目前,熔融沉积制造(fused deposition modeling,FDM)3D 打印机高速、高精的发展趋势,对FDM 3D打印机结构设计提出了更高的要求,以保证FDM 3D打印机有良好的静动态特性。本文以F500工业级FDM 3D打印机为研究对象,基于ADAMS和ANSYS建立了打印机执行机构的刚柔耦合模型。通过求解分析打印机在正弦激励信号下喷嘴处的频域响应曲线,得出对打印机影响最大的频率;通过模拟喷头小范围往复运动,研究分析惯性和滞后性对打印机喷头实际运动轨迹的影响。

Abstract: At present, the development trend of high speed and high precision in fused deposition modeling (FDM) 3D printer has put forward higher requirements for the structure design, in order to ensure that FDM 3D printer has good static and dynamic characteristics. This paper takes the F500 industrial-grade FDM 3D printer as the research object, and the rigid-flexible coupling model of the printer actuator is established based on ADAMS and ANSYS. By analyzing the frequency response curves of the nozzle of the printer under sinusoidal excitation signal, the frequency that has the greatest influence on the printer is obtained. The influence of inertia and hysteresis on the actual motion trajectory of the printer nozzle is studied by simulating the small-range reciprocating motion of the nozzle.
