Review of the effect of built orientation on mechanical Properties of metal-plastic composite parts fabricated by Additive Manufacturing Technique

Abstract

In fused deposition modelling built up orientation of the model is one of the critical factor affects economic feasibility of the models includes, main material, support material, and built up time. Built up orientation is used in the layer by layer manufacturing of the prototype which is in the semi-molten plastic filament form and built up on the platform from bottom to top. Various experimental analyses show that built orientation has also significant affect on the tensile, impact and total cost of the FDM parts. Metal plastic composite parts of ABS and bronze, Al powders were produced and tested for various mechanical properties. This paper investigate the effect of built in orientation in combination with other factors such as orientation angle, type of layer, supporting material and temperature during FDM operation on various mechanical properties. Finding of this study will help the manufacturing firms to decide on proper build orientation, so that FDM parts can be fabricated at minimum manufacturing cost with good mechanical properties
