PEEK Filament for FDM Printers

[BenB]

I posted this elsewhere, but...

We printed this spiral vase in PEEK today on our Hyrel 3D System 30M with the MK1-350 print head, which prints at up to 400C and also prints with polycarbonate.





That's the MK1-350 above the vase.

Nice done. What did you do to make the PEEK stick to the buildplate?

BenB,

We've had the best results by printing a thin layer of polycarbonate, then printing the PEEK on that. Be prepared to sand the polycarbonate off - the bond is that good. The PC sticks fine to the glass with the bed at 85C.

Please let me know if you have other questions.

Hi Davo,

thnx for the quick response, we're gonna try that.

This is Awesome! Do you know what kind of surface finishes one can expect? Is it post machinable?

MikeG3,

I haven't made any solid or mostly solid PEEK parts to try machining.

I'll post here when I do.

20 years ago we were paying £50/kg for basic PEEK, it went to £1000/kg for the good stuff that was used for human implants etc. This was in injection molding. To answer the question above, (even if it was asked 4 years ago), it does machine very well. I have some here that I mill / turn occasionally.I´m quite keen to try it on my 3D Printer, but the price puts me off!
