Effect of process parameters on additively manufactured parts using FDM process & material selection: A review

Abstract

Fused deposition modelling (FDM) is second most widely used additive manufacturing process worldwide. Performance of the FDM system is highly effected by number of parameters such as environmental factors, material properties, part orientation and supports, machining parameters and working parameters. Working parameters specifically raster angle and width, layer thickness and amount of infill highly effect the mechanical characteristics of additively printed parts. Part orientation which is directly proportional with support generation, is mandatory requirement for hanging parts but it results in poor surface finish and require more post-processing. A proper selection of material is one to the key factor of success of functional prototypes produced from FDM system. Various materials categorized as biodegradable/non- biodegradable, biocompatible, water soluble/insoluble, etc. can be processed on considered system. A various commercial and open ware software’s can be used to identify optimum value of working parameters for best results. In present work, a comprehensive review has been carried out to check the effect of working parameters on the performance of the FDM printed parts. Study also supported by the understanding of the various materials reinforced by FDM system and new possibilities are identified for future work.
