American Filament

American Filament High-quality American-made 3D printing filament made in the Rocket City Hi! We’re Megan and Thomas Brooks, founders of American Filament.

If you’re like us, you love to work with your hands, geek out over scientific advancement and, most importantly, you love to buy American made goods. We started AF after Thomas, an aerospace engineer by day, banded together with 100s of other 3D printing enthusiasts in early 2020 to print face shields for medical personnel during the PPE shortage. Watching dozens of cars line up at the US Space &

Rocket Center (in our hometown of Huntsville, Alabama) and wait to donate as many units as possible, week after week, we knew this community of makers was our community. But then, Thomas and his maker-friends couldn’t buy more filament to continue printing face shields. The pandemic highlighted how any change in manufacturing or shipping overseas –– or a change in trade relations –– could drastically impact our ability to serve our communities and continue our hobbies. So, we began to learn exactly how 3D printing filament is made and set up shop. Now, it’s our pleasure to provide our community of fellow 3D printing enthusiasts with high-quality, Made in USA filament. When you buy from American Filament, you are:
- Supporting a family business
- Standing up for American manufacturing
- Creating local jobs
- Reducing dependence on imported goods

If you’re local, swing by our shop, say hi, and pick up your filament in person (and save on shipping!). Don't forget to check out our Lithophane Maker tool over at www.LithophaneMaker.com if you haven't already!

Meet Regenerative PLA+ Filament 🌍

Watch this short video to see how Regenerative PLA+ is designed to return to the planet’s natural cycle (but only after you’re done using it) instead of lingering as microplastics - with no sacrifice in performance.

Happy Earth Day 🌎

What if your waste turned into soil instead of microplastics?

Meet Regenerative PLA+ Filament — all the performance of PLA+, with a better ending. Designed with technology, it supports a more responsible end-of-life by helping the material return to the natural carbon cycle instead of lingering as long-term microplastics.

Hard not to feel excited about tonight 🚀 Wishing the best of luck to everyone involved in the Artemis II launch. So many people have poured years of hard work into this, and it’s awesome to see it all come together.

We are really proud of the role our local community plays in missions like this—there’s a lot of Huntsville behind that rocket! Here’s to a smooth countdown and a successful launch 🤞🌙

We’ve updated our lithophane PLA filament formula to improve flow, ductility, light diffusion, contrast, and overall print consistency. We were so excited to get it out there that we even put a typo on hundreds of spools... Oops!

These improvements have been in the works for over a year, shaped by customer feedback and lots of hands-on testing. And of course, all of our design and print testing was done using LithophaneMaker.com!
