Prusa and Noctua Ship PETG Filament in Beige and Brown

Noctua does not do subtle. Those fans and heatsinks arrive in a muted beige and brown that stand out in a sea of black PC cases. Until now, getting an exact match meant mixing custom filament or painting after the fact. Prusa Research and Noctua just removed that hassle.

The two companies released Prusament PETG Noctua Beige and Prusament PETG Noctua Brown, co-branded spools tuned to Noctua's color standards. The filament ships with NFC tags, so Prusa printers can identify the material automatically and load the right profile with one tap.

PETG was a deliberate choice. PLA prints easily but softens above 50°C, which makes it unfit for internal PC parts. PETG is tougher and resists higher temperatures, which matters for custom shrouds, cable comb holders, and mount brackets that share space with hot GPUs and CPUs.

Prusa promises tolerance within plus or minus 0.02mm and tight color consistency. That precision matters when the whole point is visual matching. A slightly off shade would break the theme next to genuine Noctua hardware.

Noctua CEO Roland Mossig said the company already saw demand from builders customizing with earlier Noctua-colored PLA spools. PETG was the natural next step for anyone who needs more durability and heat resistance without leaving the color family.

The filaments ship now at Prusa3D for $32.99 per kilogram. If you run a quiet loop or a custom air-cooled build, these spools save you from painting or blending your own mixes.
