Fused-Deposition-Modeling (FDM)

A plastic filament is melted and extruded through a nozzle. Parts are built by laying down layer-by-layer.

Advantages:

  • Parts have good mechanical properties and are durable over time.
  • Can build fully functional parts in standard plastics.
  • Parts can be post-processed

Disadvantages:

  • Anisotropy in the z-direction (vertical direction)
  • Step structure on surfaces
  • Fine details cannot be realized
