Permitted materials in the Ultimaker

[peter_hellyer (Pete Hellyer)]

What is the current view on using exotic materials in the printer, such as the wood or metal composites?

In short DON’T

The problem of metal composite filament is

1. there abrasive nature
2. the metal powder size might cause blockage in the 0.4 nozzle we use.
   Wood composite filament
3. Wood fibers in most brand are likely to block the 0.4 nozzle

Finally risk assessment have not been completed on those material.
