Spectrum Filaments is a long-time high-quality filament supplier based in Poland. With good tolerances, roundness, and consistency coupled with affordable pricing, the firm has been a mainstay for makers, industrial users, 3D printing stores, and OEMs since 2015. I personally tested and evaluated them a few times over the last decade, and each time, the company’s offering performed well.
The company provides individual reports per spool for filament diameter and average diameter, measured across the entire filament (not just at one point or on one axis), to tolerances of ±0.8μm. They are also known for their Stone Age stone-look filaments and have a basic filament line called The Filament. Spectrum has high-flow filaments, foaming PLAs, electrically conductive materials, glitter, glow-in-the-dark, flame-retardant, and more. They have very high-performance materials such as PEBA, a polycarbonate-PTFE blend for durable, smooth parts; food-safe materials; PPS; and medical ABS. I’m a fan.

Spectrum has now received an investment from Blue Gravity Capital. Blue Gravity calls itself a hands-on investor that seeks to work with founders to create value. They are now the majority owner of Spectrum. Terms were not disclosed, but they said the investment was “several tens of millions of PLN,” which could mean they invested about $5 to $10 million.

The company says that it grew organically and is “one of Europe’s largest manufacturers of 3D printing filaments.” They also say that, “between 2018 and 2025, Spectrum achieved an average annual production volume growth rate of approximately 50%.” This is commendable, since it was also the time when Sunlu went from terrible to mwah, Amazon’s rise through Hatchbox and beyond, Prusa Research’s Prusament market entry, Polymaker’s rise, and general upheaval in the filament market. Showing growth at this time, and such consistent, high growth, is commendable. Many people went out of business during that period as well. Now, the company will use the investment to further scale and automate production, drive international growth, and invest in R&D. The firm hopes to double its capacity. Management will remain in place, and the company will do what it does already, only more of it.
Spectrum’s CEO Michal Zoladek said,
“Over the past years, we have focused primarily on product development, quality and building our distribution network. Today, we see the market evolving faster than ever before. In practice, for nearly five years we have operated under continuous backorder conditions, with demand regularly exceeding our available production capacity. Through our partnership with Blue Gravity Capital, we will be able to significantly accelerate investments in production capacity expansion, new material development and further development of our org
