⭐⭐⭐⭐⭐ 5 star review from David:

"***** Awesome Material - To concur with other reviews, Atomic's PCTG mostly drops right into existing PETG profiles. Very consistent quality and finish. This PCTG-CF does need to be dryed, especially is left out. 4-5 hours @ 65º does it for me.

"***** Good To Have - I use the table top spool holder for both my 3 and 1 kg rolls. it allows me to position the spool in the best place for my printer which is in a tight area to begin with. i like how the feet keep it from sliding and the bearings are smooth rolling. a well designed and easy to put together addition for my printing!"

⭐⭐⭐⭐⭐ 5 star review from Brian H.:

"***** Dependable, prints well. - I enjoy getting filament from Atomic. My first order was because I am in the nuclear power industry. Yeah, corny. However, I was pleased with the quality of the filament I used. Using the same settlings, the Atomic Filament seems to print easier and cleaner. The end result nicer looking as well. I am still pretty new to this hobby (obsession) and Atomic Filament is my go to when I need it right the first time."

⭐⭐⭐⭐⭐ 5 star review from David J.:

"***** Excellent filament - The only really dark gray filament I could find to match the paint we use, and the color is very saturated and attractive. The best part, though, was how perfectly it prints on our Bambu P1S. We can use the parts with no secondary machining or finishing. And it& #39;s not even very expensive. And this material is extremely tough and creep resistant. Will be using it for all our parts that do not need to be assembled by way of solvent welding."
