提高桌面3D打印机效率的研究

目前桌面3D打印机受到了许多领域的关注,但由于桌面3D打印机是通过逐层累加的方式来构造实体,所以与传统的切削加工相比,熔融沉积成型的桌面3D打印机生产效率较低。为提高桌面3D打印机的生产效率,提供了一种优化零件构建时间的方法。即通过零件表面采用直径为0.4 mm的喷嘴进行成型加工,填充区域采用直径为1.2 mm的喷嘴进行成型加工,并与现有单喷头方法进行对比实验,发现该方法在保证表面粗糙度不变的前提下能大幅度缩短构建时间。为提高桌面3D打印机效率提供了一种新思路。

Research on Improving Productivity of Desktop 3D Printer

At present , desktop three dimensional ( 3D) printer has gotten lots of attention in many fields .Compared with tradi-tional cutting machining , 3D desktop printer makes the parts through the principle of layered manufacturing in fused deposit to entity , which has lower production efficiency .In order to improve the productivity of a desktop 3D printer, a way to optimize part build time was provided.That is, the surface layer, the bottom and top outline were printed by nozzle of 0.4 mm in diameter, while the internal filling was performed by the nozzle of 1.2 mm in diameter.Last, through contrast experiment to the existing single nozzle process , the new process method has shortened the parts 'build time substantially , meanwhile ensured the surface roughness under the same premise . It provides a new idea for improving the desktop 3D printing efficiency .
