GoKawiilExplainer: How Fused Deposition Modeling 3D printers work
Fused Deposition Modeling (FDM) is a widely used 3D printing method that builds objects layer by layer by melting thermoplastic filament and depositing it along paths defined by a CAD file. The printer repeats this layering process, which can take hours or days depending on the machine, settings and model complexity, until the object is complete. FDM supports a range of filaments including PLA, PETG, ABS, TPU, nylon, wood and metal composites, HDPE, and PETT.
