Applications of Fused Deposition Modeling in Dentistry

Fused Deposition Modelling

FDM, is the process of creating solid things out of a thermoplastic substance (Bartkowiak & Walkowiak-Śliziuk, 2018). In this process the material is deposited in a defined thickness layer, from the point of melting the material followed by passing it through a extrusion head in a predetermined manner (Chia & Wu, 2015). This causes the material to be discharged layer by layer, and as the structure hardens, these strata are bonded together. There are typically no further processes needed on the substance itself to enhance mechanical qualities apart from support removal (Liu et al., 2006). Among the most often used processes for printing three-dimensional (3D) objects) is fused deposition modelling (FDM) (Zhu et al., 2017). This technology makes it possible to produce moulds, prototypes on demand, and parts with intricate shapes (Shofner et al., 2002). Due to its minimal production time, negligible waste and developing intricate shapes, FDM is recognizing as one of the quickly developing manufacturing technologies (J. Wang et al., 2018). FDM products' subpar surface smoothness and questionable dimensional accuracy call into question their suitability for a variety of applications. The surface texturing of FDM parts has been improved by several researchers (Singh et al., 2017). The group's researchers concluded that layering thickness is indeed the factor most crucial to the exterior roughness of 3D printed parts (Lužanin et al., 2013).
