Fused Deposition Modelling (FDM) and Selective Laser Sintering (SLS) as Indisputable Machines in Additive Manufacturing: A Review

The additive manufacturing process is one of the keys to advanced engineering manufacturing processes in this era of the Fourth Industrial Revolution. Fused deposition modelling (FDM) and selective laser sintering (SLS) are two additive manufacturing (AM) techniques that can be used for rapid prototyping. The importance of fused deposition modelling and selective laser sintering as viable equipment for advanced technology development in the manufacturing of interchangeable parts in automotive and aerospace was demonstrated in this review study. The impact of these two machines on the advancement of manufacturing technology is also discussed in this article. The findings demonstrated the enormous benefits of fused deposition modelling and selective laser sintering in the manufacturing industry for efficient and successful production, as well as the duo's applications. The purpose of this paper is to summarise fused deposition modelling and selective laser sintering as important technological tools for advanced manufacturing technology advancement. Many advantages and applications are highlighted in the study, including durability, ease of use, lower production costs, shorter lead times manufacturing process, ease of dealing with complicated cavities and geometries, several high-performance, lower tooling costs, produce customised products, and develop low-volume production, bridge manufacturing, engineering models, testing, and high-temperature applications to bring the product to market quickly.Keywords: Additive Manufacturing, Fused Deposition Modelling, Fourth Industrial Revolution, Rapid Prototyping, Selective Laser Sintering.
