The best bed heater is dirt-cheap. You put direct mains AC on the heater and
control it with a contractor that is designed for water heaters or electric
home heating. Same for the enclosure heat. You need insulation on the
enclosure; plexiglass will not be enough, the ceramic felt used on stoves works.
A cheaper solution is to re-engineer your product so that it does not require
PEEK.
Product already done in hard maple and PETG. some with CF. I was looking
for something stronger than PETG because I'd like this to outlast the
pro woodworker who buy's it so he/she who builds a workbench
incorporating this vice can pass it to their children should they want
to work in wood as some of history's craft folks have demo'd. There is
not, at any price, a similar vice screw kit on the market. I have
designed it so the only part that can be broken first is 16" of 3/4" oak
dowel for a handle, current price a couple dollars. Everything else is
designed to be strong enough to survive the force needed to break that
handle. experiment, a .gng for the nuts attached. They are identical
because the screw is 2 start.
OK, you can’t redesign the part? You can send it out to a commercial printer.
But then, “why PEEK?” have them print it in stainless steel.

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.

Richard,
Are you able to print PEEK?
Thanks
