Abstract

In this paper, a suitable prototype model part was developed. A CAD model and drawing was developed using SolidWorks program for the review of the three manufacturing processes: such as, (1) 3D Printing- AM (additive), (2) Injection Molding- IM (formative), and (3) CNC Machining (substrative) manufacturing processes.  All three manufacturing processes were simulated using SolidWorks program. The CAD model AM part file was simulated using stereolithography (STL) file, and the AM part was sliced using CatalystEX software. The IM process was simulated using SolidWorks Plastics flow simulation tool and the CNC machining process was  simulated using SolidWorks CAM program. The actual prototype model parts were fabricated using three different machine tools for the study using IM, AM, and  CNC machining fabrication processes. The same part design and the same polymer thermoplastic material is used for all three manufacturing processes. The protype type model part processes study results and the recommendations are provided.
