随着3D打印技术的快速发展,针对ABS材料进行细致分析、计算方面的研究报道逐渐增多。通过ANSYS中APDL语言编写命令流、建立模型、划分网格、施加载荷、加载边界条件、模拟计算,对ABS材料进行热应力耦合场分析,探讨了喷头温度T_1、成形室温度T2和打印速度V这3个打印参数对试样热应力耦合场的影响,最后进行打印实验,最优化结果为喷头温度T_1=200℃、成型室温度T_2=90℃、打印速度V=30 mm/s。利用这种方法可以进行PP、PVC、PEEK等多种材料的打印成型,也可以进行相关金属、非金属材料的分析与打印设置,拓展了设备使用的领域,也为其它同类型设备或稍旧设备的进一步改造使用提供了借鉴。
With the rapid development of 3D printing technology, detailed analysis of ABS materials has been reported. Through the compiling flow of APDL language in ANSYS, establishing model, dividing grid, applying load, loading boundary conditions and simulating calculation, the thermo-mechanical coupling field analysis of ABS material was carried out. The nozzle temperature T_1, forming chamber temperature T2 and printing speed V The three print parameters affect the thermal stress coupling field of the sample. Finally, the printing experiment was carried out. The optimized results were nozzle temperature T_1 = 200 ℃, molding chamber temperature T_2 = 90 ℃ and print speed V = 30 mm / s. This method can be used for PP, PVC, PEEK and other materials, printing and forming, can also be related to metal, non-metallic materials analysis and print settings, expanding the field of equipment used, but also for other similar equipment or slightly older Equipment to further transform the use of provided a reference.
