This new filament is the company's Jet Black TPU in evening wear because sometimes your RC tires, phone cases, and bendy little shock-absorbing bits deserve to feel like they’re walking a red carpet. The new Prusament PTU Galaxy Black filament keeps the serious stuff under the sparkle, including Prusa’s in-house production and tech specs, plus refill-friendly NFC-tagged spool, and costs $37.99/500g — a small price to pay for adding just enough bling to make your functional parts whisper, “I’m not like the other black filaments.”
