How does Fused Deposition Modeling (FDM) function?

Fused Deposition Modeling (FDM) operates by melting a thermoplastic filament and extruding it through a nozzle. This process involves feeding a plastic filament into a heated nozzle, which softens the filament to a semi-liquid state. As the melted filament is extruded, it is deposited layer by layer onto a build platform in a controlled manner, allowing the material to cool and solidify, forming the desired shape.

This layering technique is a hallmark of additive manufacturing, enabling the creation of complex geometries and detailed features that would be challenging or impossible to achieve with traditional subtractive methods. The ability to manipulate the extrusion process and control temperature plays a significant role in ensuring the quality and accuracy of the final printed object, making FDM a popular choice for various applications in prototyping, tooling, and production.
