FDM (Fused Deposition Modeling)

Fused Deposition Modeling (FDM) is a prominent 3D printing technology that utilizes a filament-based system to construct physical objects. The process starts with the creation of a 3D model using computer-aided design (CAD) software or by sourcing a pre-existing model. This model is then segmented into horizontal layers through specialized slicing software, preparing it for printing.

Before printing begins, the FDM printer must be meticulously prepared. This preparation involves leveling the build platform and cleaning the nozzle to ensure optimal functioning. The printer uses thermoplastic filaments, such as PLA or ABS, which are fed into a heated extruder nozzle. As the filament reaches its melting point, it transforms into a semi-fluid state.

The printer methodically deposits the melted filament onto the build platform, layer by layer. The extruder nozzle traces the designated paths based on the sliced model, laying down the material precisely. Each layer quickly cools and solidifies, bonding securely to the preceding layer, thus gradually shaping the intended object.

FDM technology offers a practical and flexible approach for fabricating functional prototypes, bespoke parts, and complex models. It supports a variety of details and can utilize different thermoplastic materials to fulfill diverse specifications. With applications spanning manufacturing, engineering, healthcare, education, and design, FDM continues to be an invaluable asset in numerous fields, democratizing production and fostering innovation.
