Fused Deposition Modeling (FDM) 3D Printing
Description
FDM is a widely used 3D printing technique that employs a heated extruder to deposit thermoplastic filament layer by layer, gradually building up a solid object. Known for its versatility and affordability, FDM is one of the most popular 3D printing methods available. Its compatibility with a diverse range of filaments makes it suitable for a broad array of applications, from prototypes to functional parts.
