3DP(Three Dimensional Printing), Photo-polymer resin, SFF(Solid Freeform Fabrication), UV curing


3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.To prepare a digital file for printing, the 3D modeling software “slices” the final model into hundreds or thousands of horizontal layers. When the sliced file is uploaded in a 3D printer, the object can be created layer by layer. The 3D printer reads every slice (or 2D image) and creates the object, blending each layer with hardly any visible sign of the layers, with as a result the three dimensional object.

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.
