Surface quality in rapid prototype MMD process

Abstract

This article summarises a Manufacturing Materials and Processes MSc thesis written for the Mechanical and Electrical Engineering Department. The paper shows the interaction of process, gap (deposition distance) and extursion terminal velocity modelled process parameters for CEIF's (Centro de Equipos Interfacultades) rapid prototype molten material deposit (MMD) Titan SH-1 machine by analysing prototupes improved surface quality and resistence to tension and characterising material. The project applies experimental design criteria for orientating the selection of experimental process parameters. Acrylonitrile-buttadin-styrene (ABS) had alredy been mechanically and physicochemically characterised (i.e the material used in the MMD process).
