Not PEEK filament, but just contemplating the idea of printing in high temperature material, I wonder if it might be possible to 3D extrude clay, then fire the resulting object in a kiln to get a 3D printed high temp part? (You'd need a print head more like a filastruder auger probably).

actually, yes, its rather easy to extrude clay. just have to swap the hotend and extruder for a syringe setup that can squirt out ceramic slurry. search youtube for 'Ceramic 3D printing' http://www.youtube.com/watch?v=_c0C8w_LdYM

If only I could get some PEEK filament made! I've tried, but no luck yet. If anyone finds or makes some I'll pay good money!

Water cooling has lots of potential in heated chambers and for many-nozzle setups, but I dont see it as being needed or even advantageous in this particular setup.

Whatever it is they are caking their heater in looks suspect. Maybe JBWeld/Epoxy type stuff or sillicone? That's not going to enjoy PEEK.

Nonetheless I wish him the best of luck, and I think his whole FOSSCAD project in general is pretty cool from an engineering standpoint.

The whole reason for water cooling is that is able to remove more heat in a smaller weight and space. Using a fan/heatsink combo works great and is entirely appropriate for a single hotend, but a heatsink for 3 or more hotends would be silly-big/heavy. Using water lets us pack nozzles tightly under a compact lightweight cooler block. The individual nozzles aren't themselves going to perform significantly differently to an air cooled one, it's the fact that you get get more of them.

There is also the very valid point that op7ical makes, heated chambers mean that fan based heatsinking doesn't work effectively. Our testing and feedback from customers who have tried it point to 50C ambient being about the tops for the air-cooled E3D. Water obviously solves this issue.

But why?

E3D does 300C all day long, nylon and polycarb are no problem. No hassle of watercooling. Only a few bucks more than a J-head. A no-brainer, really.

The E3D looks really tidy and professional, where as that new one is ugly as sin.


+1  ugly as ever...

According to E3D:

This hot-end has been tested to beyond 400 degrees centigrade
