A Review of FDM Based Parts to Act as Rapid Tooling
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 11
Abstract
Fused Deposition Modeling (FDM) is one from basic Rapid Prototyping (RP) technologiesused in technical practice. In this contribution are presented basic information about parameters such as layer thickness, part build orientation, raster angle, raster width and air gap. This study provides insight into complex dependency of strength on process parameters. In this paper microphotographs are used to show the mechanism of failure. The major reason for weak strength is attributed to distortion within or between the layers.Developing a curved layer deposition methodology can improve part quality by reduced lamination, reduction in the staircase effect which leads to improved dimensional accuracy of the part. Less effort has been made to increase the range of FDM materials to include metals or metal based composites with the help of metal based composite direct rapid tooling will allow fabrication of injection moulding dies and inserts with desired thermal and mechanical properties suitable for using directly in injection moulding machines for short term or long term production runs
