These values are taken from the manufacturer datasheet and apply to the material, not to the printed part. In 3D printing the achievable properties depend on part orientation, layer height and process parameters – in the Z direction in particular they are lower. Please talk to us before relying on them for design.

“Qualified for functional parts” is a general classification. A functional part can be a simple clip or a main load-bearing member – the forces and load cases differ fundamentally. We therefore always assess in each individual case whether a material is suitable for your part.

Strengths

  • Outstanding chemical resistance
  • Very good UV and weathering resistance
  • Inherently flame retardant
  • Finer detail achievable than via the pellet route

Limitations

  • Corrosive decomposition products on overheating – extraction is mandatory
  • Considerably more expensive than standard plastics
  • Layer adhesion requires careful parameter selection
  • For large parts the pellet route is more economical
