Abstract

Fused deposition modelling (FDM) is a three-dimensional (3D) printing method under an additive manufacturing process. The process of FDM runs by depositing a melted filament which is a built material, layer by layer on a printing bed. Recently, various types of materials have been made and used as build materials that have their functions and properties. Metal composite is considered a new type of material in the FDM process, yet it has a wide range of applications in the manufacturing industry.The use of metal composite in FDM is quite challenging because of some shortcomings in terms of mechanical properties and surface roughness exist in this process. Due to the anisotropic feature of an FDM printed part, the mechanical properties of the specimen are affected such as tensile strength and flexural while different types of materials are used to give different surface finish on the printed part. Additionally, the mechanical properties and the surface roughness also are influenced by the printing parameters where the manipulation or adjustment on these parameters will give different results on these two properties. Layer thickness, infill density, raster angle, and printing temperature are among the printing parameters that can be altered. The use of optimal printing parameters for the metal composite can produce high-quality products and be able to contribute to developments in the manufacturing industry in the future. Therefore, a review study on the effect of printing parameters of FDM metal composite parts on the mechanical properties and surface roughness was carried out.
