Abstract
Abstract Rapid prototyping (RP) technologies provide the ability to fabricate initial prototypes from various model materials. Fused deposition modeling (FDM) and 3D printer are commercial RP processes while nano composite deposition system (NCDS) is an RP testbed system that uses nano composites materials as the part material. To predict the mechanical behavior of parts made by RP, measurement of the material properties of the RP material is important. Each process was characterizes by process parameters such as raster orientation, air gap, bead width, color, and model temperature for FDM. 3D printer and NCDS had different process parameters. Specimens to measure compressive strengths of the three RP processes were fabricated, and most of them showed anisotropic compressive properties.
