ABS塑料3D打印过程中热应力耦合场分析与优化
|
摘要
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 3 D printing technology in recent years,lots of research target on ABS analysis and calculation had increased gradually. Using APDL of ANSYS,command stream was edited,model was created,grid was divided,load was applied,boundary was defined and simulated,ABS material's thermal stress coupling field was analyzed,and how it would be effected was tried to find out by 3 printing indexes for head temperature T_1,room temperature of forming T_2 and printing speed V. Physical printing tests indicated that the printed objects performed best when T_1= 200 ℃,T_2=90 ℃ and V = 30 mm/s. The method could be used in PP,PVC,PEEK and other materials' printing,as well as relative metal and non-metallic materials' analysis and printing,which could expend the equipment usage scope,and offer a reference in reform of the same type equipment.
