Gene,
PEEK has a melting temp of ~360 C and a printing temp of up to 450 C.
That is pretty warm Stuart, and beyond the reach of my rebuilt printers.
Who makes 500C hotends that could be retrofitted?
And thanks for the prompt reply.

Chris, are you able to consider a part from a private individual? I have
a
single small PEEK part. Ultim 1010 would be a little better. It is a
repair
part for an automotive radiator. I can supply a solid model and/or an STL
file.
Stuart:
What sort of temps are needed for PEEK? I have what I thought was a
comprehensive chart of such, but it doesn't have a reference for PEEK.
Apparently the composer of this chart wasn't concerned with materials
needing more than 300C nozzles. Even that is getting pretty far into the
far end of heater lifetimes mortality curve. I do some PC, but even at
285C I'm losing heaters in 100-150 hrs. That also needs a bed temp
around 100C, well beyond most under $1500 printers. The printer I've
rebuilt to do that, an Ender 5 Plus now has 72 volt closed loop
stepper/servo XY motors, and a 36 volt bed supply that an get to 125C. I
also have a Sovol sv08 MAX. Which is acting like its going to be my next
fav printer. Either one warms up a 15 amp breaker in the service.
Thanks

I am unable to print PEEK.
PEEK needs a very high temperature nozzle, very hot build chamber, etc.
Chris Rempe has fancy and very expensive 3D printers; he may be able to
help you.
