RE: Printing with Polypropylene (PP)
Doh! I feel stupid. I must have used that before but somehow now completely overlooked it. Yes, indeed, it's all there.
I'd like to print some parts with flexi hinges and PP seems one way to go (maybe not Prusa's PP-CF or PP-GF though). Only it's not vital, just a nice to have and now that I don't have to dedicate a lot of time to presets it's within my 'capability'! Thank you.

Definitely not PP-CF or GF for hinges. Pickup a roll of Sunlu or Yousu PP for that. Let me know which one you get and I'll send you a profile to use. Also, I find it better to print with a standard 0.6mm (not HF) nozzle. A 0.4mm nozzle works fine as well. PP prints slow so having a larger nozzle will help with layer adhesion. Also, do not buy the Prusa PP sheet. It's a waste of money. Just go onto Amazon and look for the Yousu PP sheets. They are adhesive PP sheets that stick to your print sheet. You print on it, then peel it off when you are done. You can use them more than once. Otherwise, you can use polypropylene packing tape.
RE: Printing with Polypropylene (PP)
Thanks, all understood. I just sent for some FormFutura Centaur PP in white from eBay. The profile seems available in Prusa Slicer. Will go looking for the PP sheets, thanks. I've got 0.4 and 0.6 HF nozzles; are you saying that in both cases a non-HF will perform better with PP? Or would just slowing down the print by 50% work just as well?

A HF nozzle should be OK. PP can be kind of stringy and gooey so I tend to avoid HF nozzles with that kind of filament. Less likely to clog. When setting up a profile you will want the max volumetric flow to be around 6 mm^3/s. But that depends on whose filament you pick up.
My advice is to pick up a non-HF hardened nozzle. If you don't plan on using the INDX system and you don't have immediate budget constraints, get a E3D Diamondback. It'll last you forever.
RE: Printing with Polypropylene (PP)
I see. Problem is I already have a hardened 0.4 (Obxidian) which is HF - and great! Maybe I get a 0.6 Obxidian. Oh, that'll be HF too. Maybe not then. But I do value the HF property, so might just live with my std HF 0.4 and HF 0.6 nozzles, and their slight drawback with PP. Or just buy a cheap std 0.6 brass non-HF. Too many options !!
RE: Printing with Polypropylene (PP)
BTW the Yousu PP sheets appear to be currently unobtainable. I'll give them a couple of weeks ...

Polyproplyene will only stick to itself. So anything made of polyproplyene will work. You can search for PP adhesive sheets and find them pretty much anywhere. Also PP packing tape works. I've used both. Otherwise, you can use Magigoo PP on a satin or textured sheet.
