Polymaker polyterra. I especially love their army blue and black filament. They print nice and matte, and the colors print almost identical between their different colors. I always thought polymaker was a more expensive brand, but polyterra hits that 20usd/kg for pla price point that hatchbox and other budget filaments used to dominate
I like the polyterra line too. My favorites are the cotton white and sapphire. I’ll have to give the army blue a try sometime. I’ve tried a spool of their polycarbonate and it was nice though difficult just due to the nature of polycarbonate. I also used to think polymaker was expensive brand but I’m so glad it’s affordable.
Just went from azurefilm to polimaker politerra recently and its amazing
The muted red polyterra feels like terra cotta a little. The matte additive is really dense, so parts feel heavier than other parts (polyterra PLA and PETG are the two densest non-filled filaments I've used). Whatever the additive is, it also increases the strain to failure by a lot, so it's less brittle.
My only complaint about polyterra is that it is not as good at layer adhesion as the regular PLA/PLA+. I can't push my printer to the limit on speed without getting a part that wants to separate at the layers, so I have to slow the print speed and slow the fan down, and I usually print a little warmer.
I'm finishing up my first Polyterra PLA+ print right now. It has less of the additive so it's advertised as a satin finish more than a matte finish.
For what it's worth, I just bought my first 3kg roll of filament for a big project, and I chose polyterra PLA in black.
I usually print Polyterra PLA at 210C but I had some issues with it lifting off the glass bed on my Enders. I never tried printing it below 205C and I have yet to try it on my Neptune 3 max so maybe the lifting issue won’t be a big deal with the PEI sheet bed. It does kind of feel like a terracotta texture which makes me want to try that red out now.
I wonder if I tried printing it at even lower temperatures if I would also get the delamination issue like you had.
It’s been a while since I bought from Polymaker and I don’t remember seeing that satin finish PLA+ line before but I’m definitely going to look into it. I also saw they are now offering dual color Polyterra matte filaments which is super cool.
