Plan on a 360–450°C hot end, 120–160°C bed, and a fully enclosed, actively
heated chamber (70–150°C). But general guidelines are not enough. It
depends on the exact brand of filament and your own testing.
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.
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.
