锡作为3D打印材料的应用研究

Feasibility Analysis of Tin in the Application of 3D Printing Materials

熔融沉积3D打印机所用的材料形态为卷材,分析了锡丝与应用到熔融沉积3D打印机上的ABS、PLA卷材在熔点、力学性能、收缩率以及材料熔化或软化后的粘性等性能上的区别。结合锡材料的相关性能,讨论锡丝在熔融沉积3D打印机上应用的可行性,并从打印速度、层厚、温度3个参数入手,采用控制变量法,以锡丝堆积的长度与喷嘴行走轨迹总长度的比值为研究对象,对锡丝的堆积成型进行试验研究,最后对试验结果进行分析,得出实用结论,指出以后相关研究的方向。

The materials in the form of coils are usually used in the fused deposition 3D printer.The difference between tin wire and ABS,PLA coiled material applied to melt deposition 3D printer was analyzed in this paper,such as melting point,mechanical properties,shrinkage,viscosity after melting or softening and so on.Combining with the relevant properties of tin materials,the feasibility of tin wire applied in the fused deposition 3D printer was discussed.Starting from the three parameters of printing speed,layer thickness and temperature,our team took the ratio of the length of tin wire to the total length of the nozzle s trajectory as the object to study the stacking forming of tin wire by using control variable method.Finally,the results were analyzed to obtain a practical conclusion and the direction of related research was pointed out.
