Let customers speak for us
from 160 reviewsVery good match for Green Bay Green. Avoid printing in a Bambu AMS: I had a lot of problems that even printing a spool cover couldn't solve. Quality material overall and it was good to buy from a local company. Hopefully the filament rolls become compatible with AMS units as this is the way!
Fast shipping and love the Plum Purple color!
Love this stuff
The color is spot on for GB Packers. Prints great, but is a nightmare to try to use with a Bambu AMS. Had multiple jams and it required constant supervision.
Quality filament, low prices, and great service, best of all made in the USA
Perfect for packers printing
Great product and team. This is the only place I buy filament now.
My first print with this brand and it’s beautiful. I ordered Desert Tan for a train body and it was perfect. Will be buying again!
Super soft material, printed well once I figured out the parameters. It did NOT work at all in my Prusa XL. This soft material definitely needs a direct dual drive extruder head like the one on the Prusa MK3S+ that I had to go back to. Once I did that I was able to get a nice solid elastomeric print.
Again, I tried numerous things to get rid of the stringing, but never found a way to not create it. Just meant more cleanup on the back end, but was totally worth it for the springy result.
I would recommend this material. Next time I will try it with some color in it.
My only request is that you package the filaments in resealable bags.
Love this neon green filaments. Super bright and most importantly OPAQUE. My new go to
the green was the perfect green for a GBP 3D project, highly recommended it!
it works great, no issues!
Worked out great.
I’ve bought several rolls of filament of this color over the last few years, the filament is excellent. Color seems consistent between the rolls and prints very nicely. Have had zero issues.
