ZIRO Carbon Fiber PLA Filament 1.75mm, Black

The PLA I have used. Great color and smooth finish.

I'd give this one 6 Stars if I could!
Absolutely beautiful filament, prints perfectly, great finish, good bed adhesion (Prusa Mk3S).
One of my favorite PLA filaments. Printed 2 rolls to build a Hadley Telescope without a single problem - including some massive prints using both .4 and .6 nozzles.

Just beware that this isn't a dark black filament. It's more of a deep space gray or gunmetal gray. I actually reached out to the ZIRO3D customer service asking about the color and they responded and answered all my questions within 24hrs which I thought is amazing. Aside from the color not being a deep black, this stuff prints amazing. Even on my old ender 3 pro. I will be buying more from ZIRO3D. I did also measure the thickness of the filament and they are spot on at 1.75mm. I recommend this brand and their amazing customer service.

I have no complaints. It prints great, even at 200 mm/s. Its super tough and durable too. Jands down my favourite filament for anything that needs to be strong.

The smoothness, color, adhesion, everything is perfection. The impregnated CF hides layer lines incredibly well even on .28mm height. I honestly can't imagine printing any functional part with regular PLA again. For engineering/prototyping purposes this is just unbeatable.
