Abstract

This study uses fused-deposition modeling (FDM) to produce thin melted glass for 3D printing at 1,300 oC. A melt-extrusion module by the authors [Wei, 2014, 2016] has been used to produce 3D structure of alumina/polymer mixtures and Cu-Zn key parts. In this work, we determined the extrusion characteristics of various feedstocks (one borosilicate glass and simulating fluids) and to determine the kinematic behavior of the fluids. PVB-solvent mixtures were synthesized for simulating the viscous characteristics of melted glasses and extruded through ceramic nozzles of 0.1~0.4 mm diameter at room temperature to simulate an oxide glass that was extruded at 1,000 - 1,300 oC. The air-pressure, the die-diameter, the extrusion rate, the viscosity of the melts and the friction between the wall and the container was calibrated and measurement. Five major forces acting on the module were discussed in order to reveal the extrusion behavior of continuous glass fiber
