3D printing method of multi piezo head using a photopolymer resin

摘要

Recently, Study of 3D freeform fabrication method was working in the various applications. SFF (solid freeform fabrication) technologies are being developed for diverse processes. 3DP (three-dimensional printing), one of these SFF technologies, confers the advantage of high-speed processing at low cost, since it makes use of multi-nozzle inkjet printing. In this paper, we introduce a method of 3D freeform fabrication using a curing of photo-polymer resin and construct a system has multi printing head. A photo-polymer curing method has simply fabrication process and high strength of manufacturing part. We construct the printing system using multi piezo print head and it needs the heating system for lower the high viscosity of photo-polymer resin. In the result of experiment, printing system has not need the heating system because low viscosity photo-polymer resin is possible to jetting in the normal temperature. In the conclusion, we fabricate the 3D freeform part, which is suitable to the office environment using a photo-polymer curing method.
