Overview
Fused-deposition modeling (FDM), also known as fused filament fabrication, is an additive manufacturing process that builds three-dimensional objects layer by layer from a thermoplastic filament. In this process, a spool of plastic filament is fed into a heated nozzle that melts the material and deposits it precisely along a path defined by a digital model, with each layer fusing to the one below as it cools and solidifies. FDM is among the most widely used 3D printing methods because it is relatively low in cost, straightforward to operate, and compatible with a range of thermoplastic materials, making it popular for prototyping, education, hobbyist use, and the production of functional parts and tooling. Print quality depends on factors such as nozzle and bed temperature, layer height, print speed, material choice, and machine calibration, all of which affect strength, surface finish, and dimensional accuracy. Within 3D Printing and Applications, FDM is studied alongside other additive techniques for its capabilities, limitations, and growing range of uses across engineering, manufacturing, and biomedical fields, including the fabrication of scaffolds and other components from biocompatible materials. This page gathers peer-reviewed, open-access research relevant to fused-deposition modeling and additive manufacturing processes.
