In combination with the fact that no expensive tools are required to produce a part dramatically, reduces lead times that would otherwise be required to produce functional products. Additionally, DDM processes use much less material than conventional methods because fabrication is a result of adding material instead of removing it, thus reducing waste. At the time the present project was undergoing, the research teams have access to DDM technologies at both MU and KAU, specifically Fusion Deposition Modeling (FDM) and Selective Laser Sintering (SLS). FDM process is displayed in , while SLS is displayed on. Both technologies were use in the early prototypes. Because FDM uses larger variety of thermoplastic materials than SLS, the final concepts were built using FDM process.
