In this study, we research moldability and shape-holding property by FDM (Fused Deposition Modeling) type 3D printer as teaching works by students in total design education. Its lecture has learned at department of mechanical engineering in fourth grade of National Institute of Technology, Gunma College. Though 3D printer is easy and fast for make objects, it is important for strength and shaping to make design.
The test specimens printed with several direction by FDM 3D printer and made by several color ABS (Acrylonitrile-Butadiene-Styrene resin). The evaluation examined the correlation between the density, dimensional precision and Stress–strain curves. Elastic modulus measured by general gauge length method. These results valuated dimension errors and tensile strength data of the 3D objects by various materials and conditions of the printer.
