摘要
FDM熔融沉积技术是3D打印技术中较为成熟的技术,它是通过对丝状材料加热至一定合适的温度后使其成为熔融状态,然后从3D打印头中喷出,并逐层堆积成型,但其打印精度较低,除了材料的限制,物料在输送过程中会产生热,若3D打印头的温度过高,丝料从喷头喷出逐层堆积成型存在气孔,大幅度降低了精度,所以温度对3D打印喷头的影响不可忽视,也对精度产生了直接的影响。对于3D打印技术仍还在一个不断发展和优化创新的阶段,3D打印喷头也在不断优化。文章主要论述3D打印技术中3D打印喷头的分析。
FDM fused deposition technology is relatively mature in 3D printing technology,it is through the filamentous material heated to a certain temperature to make it become a molten state,and then from the 3D print heads,and pile forming step by step,but its printing precision is low,in addition to the limitation of material,material in the process of conveying produce heat,if 3D printing nozzle temperature is exorbitant,silk material from the nozzle jet pile forming pores,step by step greatly reduces the accuracy,so the influence of temperature on the 3D print heads can not be ignored,also has a direct impact on the accuracy.3D printing technology is still in a stage of continuous development and optimization innovation,and 3D printing nozzle is also being optimized.This paper mainly discusses the analysis of 3D printing nozzle in 3D printing technology.
