3D printing using Fused Deposition Modeling (FDM) is a technology for the manufacture of individual parts with particular or speci c applications that cannot be found regularly in the mass market. Printing time can take hours or days, which is a weakness in the technology of 3D printing. Printing time was analyzed from two perspectives: volume and shape for regular small size pieces. Through 3D print preparation software, simulated printing time can be con gured by many parameters that in uence both printing time and the print quality. Through this study, under the Taguchi Design of Experiment methodology, could be identifi d that packing density and print speed are the most in uential parameters in printing time, for these kind or pieces.
