摘要
在喷射式3D打印过程中,要求材料以单个微滴的形式连续喷出并按指定路径逐滴进行堆积,但材料喷射可成滴性受驱动气压、压力作用时间及材料粘度等因素的影响,难以直接找到一组合适的参数组合进行打印.本文采用正交试验法研究各因素对材料喷射可成滴性的影响规律,并利用数值模拟进行验证,结果表明,在给定喷头几何参数的情况下,利用本文制定的方法可以较为简易地获得满足微滴喷射的最佳打印参数,可有效地缩短打印的准备周期及参数调整周期.
In the processes of 3Dprinting,it requires the fluid materials to be ejected in the form of micro drops and then accumulated drop by drop.However,it is difficult to directly get a suitable combination of printing parameters,which is influenced by the factors such as the pressure,the pressure time and the material viscosity.In this paper,the orthogonal experimental method is used to study the influence of various factors on the drop property of the material;and then the method is verified by some numerical simulations.The results show that the method presented can get the best printing parameters conveniently;and the periods of printing preparation and adjust the parameters can be shortened effectively.
