Fused Deposition Modelling
- Pre-processing: Build-preparation software slices and positions a 3D CAD file and calculates a path to extrude thermoplastic and any necessary support material.
- Production: The 3D printer heats the thermoplastic to a semi-liquid state and deposits it in ultra-fine beads along the extrusion path. Where support or buffering is needed, the 3D printer deposits a removable material that acts as scaffolding.
- Post-processing: The user breaks away support material or dissolves it in detergent and water, and the part is ready to use
Advantages: Fast, Low (Tooling) Costs, lots of different materials to be used.
Cons: Low-Mid accuracy, postprocessing.
