Moving away from PetG to High Temp PLA, recommendations?
Hi
I have printed with PetG and got away with switching between it and PLA until about the 5th time after which I had a nozzle jam. I was using the atomic cleaning / cord pull method when switching from PetG to PLA. I have read that if you switch between filament types it is a good idea to by a print nozzle for each type of filament.
I would like to only stick with PLA and would like to get feedback on user experiences with high temp PLA.
Questions:
-What brands are good
-Any nozzle jamming, do you have to do the atomic cleaning / cord pull when going to normal PLA
-Did you have to cure the PLA as recommended by some makers
-How did it preform
-What temp range was the part used in
-How did the part compare vs. parts printed with PetG
Thanks for any information you can supply.

Re: Moving away from PetG to High Temp PLA, recommendations?
My favorite high temperature PLA is from an austrian manufacturer call Extrudr, the filament is called GreenTec from their "BDP" biodegrable range of products. https://extrudr.eu/collections/bdp/products/extrudr-green-tec-antrazit . I've seen various resellers across europe starting to keep stock of it.
Its good up to 120°C according to the manufacturer. I tested sample prints in a 75°C hot water bath for 10 minutes and no problems - PLA was squishy after that. No curing necessary. I print it with standard PLA settings, a bit on the cooler side (190°C-200°C). It has a sllight tendency to warp but sticks very well to PEI on my MK2, maybe a bit too well. Needs a moderate squish. Printed parts are bit stronger than with standard PLA, i printed desk clamps that kept breaking with PLA but hold nicely in Greentec.
I do cold pulls pretty much every time i load/unload filaments, so I cant answer that one and I don't print with PETG, so i cannot compare the two.
Downside: at 55,00 EUR per kg it is rather pricey.
(A very similar if not the same filament is sold as "Biofila PlaTec (by twobears)" in the US
