This paper reported the tensile strength of the difference of modeling condition on the FDM (Fused Deposition Modeling) 3D printer. The FDM 3D printer is rapidly spread with the end of patent protection in 2009. The FDM models mainly use the prototyping part and art, because that models have low strength. This time we paid attention to that actual models weight is lighter than designing models weight to conduct study on strength. And we investigated the cause of the phenomenon of decrease of polymer extrusion by replacing with the injection molding method. The tensile test proved that the strength of model can be improved by the kind of extruder head. This paper reported influence of the cooling in the supply part of extruder head and temperature of the polymer on the strength of FDM 3D models.
