About Atomic Filament

Atomic Filament Spools

Premium 3D Printing Filament. Made in America. Since 2014.

Atomic Filament was founded in 2014 by Mike, a 3D printing enthusiast who—like many of us—grew frustrated with the poor quality and limited material options of the time.

With a background in industrial automation and a deep understanding of the industry’s shortcomings, Mike set out to build a brand that would prioritize one thing: uncompromising reliability.

Today, Atomic is a staple for both hobbyists and industrial manufacturers. Mike remains hands-on, obsessively improving our processes to ensure that every spool you receive delivers consistent, high-quality results.

We thrive on your feedback. By listening to you, we continue to develop new polymers, custom colors, and specialized additives to help you bring your most ambitious projects to life. We love seeing what you create—thank you for being a part of the Atomic journey.

Happy creating,
The Atomic Filament Team

🌳 Renewable PLA Materials

Our PLA filaments are made from plant-based, renewable sources including corn starch and sugar cane — not petroleum. Lower carbon footprint, biodegradable under industrial composting conditions.

🇺🇸 Made in Indiana = Lower Carbon Footprint
