Effect of Process Parameters and Material Selection on the Quality of 3D Printed Products by Fused Deposition Modeling (FDM): A Review

Advances in Polymer Technology, Journal Year: 2024, Volume and Issue: 2024(1)

Published: Jan. 1, 2024

This work presents an investigation on the quality of parts manufactured using fused deposition modeling (FDM), which is influenced by a large number different elements. Some are based materials used in production part, though others rather pertinent to process parameters. The manufacturing and filament formulation has also significant impact cost final product, as well its physical, mechanical, thermal properties. As result, judicious combination parameters can effectively act toward fine‐tuning FDM three‐dimensional printing (3DP) pieces with fit‐for‐application. In this sense, use design experiments (DOEs) often needed for purpose. Printing parameters, including layer height, wall thickness, temperature, velocity, tool path, have been discussed, understanding that 3DP time increases decreasing turn overall cost. A specific account given recent developments increasingly more thoroughly focused recognizing raw product.
