摘要
粘结剂喷射3D打印技术的优势在于成型效率高、可适应的材料种类丰富、材料利用率高、可打印的零件几何形状相对丰富等.本文基于某品牌压电喷墨打印头在金属3D打印机的应用效果,从喷头喷墨控制、喷头安装精度以及供墨系统稳定性的角度,探讨、分析生胚表面产生某些缺陷的原因,提出改善生坯表面质量的方法.
Abstract
The advantages of adhesive jet 3D printing technology lie in high molding efficiency,a wide variety of adaptable materials,high material utilization,and relatively diverse geometric shapes of printable parts.Metal binder 3D printing,as a typical representative of current 3D printing applications,has a broad application market.Printing metal products formed by sintering of green billets is a hot topic in the current mechanical manufacturing industry and a hot research direction in the field of 3D printing.One of the current directions for the development of metal binder 3D printing technology is to improve the accuracy and quality of printed products,which can serve various industries at a higher level.This article is based on the application effect of a certain brand of piezoelectric inkjet printhead in metal 3D printers.From the perspectives of nozzle inkjet control,nozzle installation accuracy,and ink supply system stability,it explores and analyzes the reasons for certain defects on the surface of the green body,and proposes methods to improve the surface quality of the green body.
