FDM

FDM – Fused Deposition Modelling

This method offers high levels of dimensional and geometrical accuracy. An application that requires specific thermoplastic properties often means that FDM technology is the preferred choice.

FDM technology allows the creation of strong plastic products

Where larger items need to be produced, we can produce in several passes and then glue the individual parts together. The maximum dimensions we work with are 406 mm x 355 mm x 406 mm.

Technical data

Parts are made with FDM technology by fusing and extruding different thermoplastics over successive layers. The machine first lays out one or more contours, which are then filled with a grid alternating 90° on every second layer. It is worth noting that there will be so-called voids (small holes) where the grid turns towards the contours; the parts are therefore not watertight. There is a choice of many different thermoplastics, and this is also one of the strengths of this technology. A water-soluble support is used for most materials, so the support for complicated geometries can then be washed off. For parts made from Ultem, however, the support must be removed mechanically, which imposes some limitations on how complex parts can be when printed from this material. FDM technology delivers good dimensional accuracy, but slightly worse resolution than competing technologies. The layer thicknesses we use are 0.17 or 0.25 mm. Some materials can only be printed with 0.25 mm. The time required for manufacture using FDM technology differs from other technologies; the synergy effects from building many parts simultaneously are not as evident as with SLS technology.

Guidelines

  • There is a choice of many different thermoplastics, and this is also one of the strengths of this technology. 
  • A water-soluble support is used for most materials, so the support for complicated geometries can then be washed off. 
  • For parts made from Ultem, however,
    the support is removed mechanically, which imposes some limitations on how complex parts
    can be when printed from this material.
  • Best strength in X/Y. Weaker in Z
