Spectrum Filaments secures strategic investor. Blue Gravity Capital acquires majority stake

Spectrum Group, owner of the Spectrum Filaments and The Filament brands and Europe’s largest manufacturer of 3D printing filaments, has secured a strategic investor. Blue Gravity Capital has acquired a majority stake in the company. The transaction is valued at several tens of millions of Polish zloty, though the detailed financial terms remain confidential. The capital raised will be used primarily to double production capacity over the next several months, further automate processes, and accelerate international expansion.

From a Warsaw suburb to the European stage

Spectrum Group Sp. z o.o., headquartered in Pęcice just outside Warsaw, was founded in late May 2015. The company’s founder and current CEO, Michał Żołądek, started from something seemingly modest. Spectrum debuted with a line of PLA and ABS materials offered in pastel and saturated colors that were unusual for the time and stood out clearly from the competition. In an industry where most manufacturers focused on functionality, Spectrum set out from the beginning to differentiate itself through aesthetics and quality. The first product to catch the attention of the European market was the Stone Age series, filaments that imitated a stone-like texture and effectively concealed print layers.

A decade of consistent growth

For the first several years, Spectrum grew almost entirely organically, without external capital and without any headline-grabbing investment rounds. The company built its position one product at a time, one market at a time. The results proved impressive. Between 2018 and 2025, the average annual production volume growth rate was approximately 50%, significantly outpacing the growth rates seen across most European competitors. Today, the company’s portfolio includes over 100 materials designed for hobbyist, professional, and industrial applications, with Spectrum products reaching customers in more than 40 countries worldwide.

The problem that feels like success but hurts like a bottleneck

The paradox of Spectrum’s success was that for nearly five years the company operated under continuous backorder conditions. Demand regularly exceeded available production capacity. For many companies, that would sound like a dream scenario. In practice, it meant customers had to wait and the company could not fully capitalize on its market position. Michał Żołądek openly acknowledged that purely organic growth was no longer sufficient and that the time had come for external capital support.

New investor, same strategy

Blue Gravity Capital is a fund focused on profitable, fast-growing companies in Central Europe, with a particular emphasis on Poland. According to the fund’s representatives, Spectrum met every criterion for an ideal investment: a strong product, significant export potential, and a founder with deep industry expertise. Wojciech Fedorowicz, Managing Partner at Blue Gravity Capital, noted that the 3D printing materials market is currently at a particularly exciting stage, with increasingly accessible printers directly driving demand for filaments. The ambition of both parties is to build one of the key players in this segment at a European scale.

What changes, and what stays the same

Spectrum emphasizes that the transaction does not represent any change in the company’s strategic direction. Michał Żołądek remains as CEO and will continue to oversee the company’s development. The existing management team stays fully intact. The capital raised will go toward expanding production capacity, automation, international growth, and accelerating the development of new materials. For customers, this is expected to mean better product availability and shorter lead times.

Spectrum Filaments started with pastel PLA filaments in a suburb of Warsaw. Eleven years later, the company is signing an investment deal worth tens of millions of zloty and planning to double its output. The 3D printing industry has matured enough to attract serious capital. And this Polish filament manufacturer has clearly matured right along with it.
