I know that Stratasys FDM produces a porous part, but I am not sure about the
ultimate heat resistance of their plastics.
An alternative method would be to produce a rigid pattern using SLA or other
RP process, and then cast an ESPOR porous mold as a reverse impression from
such pattern. The ESPOR mold will be micro-porous and it will be resistant to
your temperature conditions. It will also pick-up all surface details. We
use this technology for reproducing complex textures for thermoforming
automotive interior components. ESPOR casting technology allows incorporation
of internal cooling lines for production requirements.
On the other hand our METAPOR machinable porous materials will handle the
required temperatures without any problems, and depending on geometry CNC
milling may be faster and any RP layering process.
