Prusament

Prusament is the filament and resin brand manufactured in-house by Josef Prusa, born from the decision of printer maker Prusa Research to produce its own materials after finding the quality of filaments on the market unsatisfying. The process is monitored and tested for string diameter, colour consistency and mechanical properties, with premium-grade raw materials.

The brand guarantees a diameter precision of plus or minus 0.02 mm for most materials, against an industry standard it considers insufficient at 0.05 mm, and it is the only manufacturer that lets customers inspect a single spool: scanning the QR code opens data on diameter consistency, weight, length, ovality and standard deviation. The catalogue covers PLA, PETG, PC, PA11, TPU, PP, Woodfill, PEI 1010 and recycled rPLA, alongside resins for Model, BioBased and Flex printing.
