摘要:

熔融沉積3D打印機所用的材料形態為卷材，分析了錫絲與應用到熔融沉積3D打印機上的ABS、PLA卷材在熔點、力學性能、收縮率以及材料熔化或軟化后的粘性等性能上的區別。結合錫材料的相關性能，討論錫絲在熔融沉積3D打印機上應用的可行性，并從打印速度、層厚、溫度3個參數入手，采用控制變量法，以錫絲堆積的長度與噴嘴行走軌跡總長度的比值為研究對象，對錫絲的堆積成型進行試驗研究，最后對試驗結果進行分析，得出實用結論，指出以后相關研究的方向。

Abstract:

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�餾 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.
