Abstract
Fused deposition modeling (FDM) is an additive manufacturing (AM) process that is often used to fabricate geometrically complex shaped prototypes and parts. It is gaining popularity as it reduces cycle time for product development without the need for expensive tools. However, the commercialization of FDM technology in various industrial applications is currently limited due to several shortcomings, such as insufficient mechanical properties, poor surface quality, and low dimensional accuracy. The qualities of FDM-produced products are affected by various process parameters, for example, layer thickness, build orientation, raster width, or print speed. The setting of process parameters and their range depends on the section of FDM machines. Filament materials, nozzle dimensions, and the type of machine determine the range of various parameters. The optimum setting of parameters is deemed to improve the qualities of three-dimensional (3D) printed parts and may reduce post-production work. This paper intensively reviews state-of-the-art literature on the influence of parameters on part qualities and the existing work on process parameter optimization. Additionally, the shortcomings of existing works are identified, challenges and opportunities to work in this field are evaluated, and directions for future research in this field are suggested.
Highlights
Fused deposition modeling (FDM) is used to produce visual aids, conceptual models, and prototypes, but it is used to produce functional parts such as drilling grids in the aerospace industry [1] and edentulous mandible trays [2]
As of the time of writing, researchers are still working on developing new materials, as well as improving existing materials used in fused deposition modeling (FDM) parts in different fields such as aerospace, biomedical, and many other fields
To complement the two reviewed papers, this paper aims to fill the gaps by systematically representing current and future research trends carried out by researchers on FDM process parameter optimization and their influence
Summary
Fused deposition modeling (FDM) is used to produce visual aids, conceptual models, and prototypes, but it is used to produce functional parts such as drilling grids in the aerospace industry [1] and edentulous mandible trays [2]. It reduces assembly cost as it is capable of manufacturing complex geometry and flexible function parts from a stereolithography (STL) file by depositing two-dimensional (2D) layers on a build platform. The FDM process has several parameters that have a significant impact on built parts. An important role is played by the use of the best thermoplastic polymer for the proposed use of the part
