Manufactured In-House By Josef PrusaPrusa Research was not satisfied with the quality of filaments on the market. So they decided to make their own! Prusa Research is the only 3D printer manufacturer with its own filament production. |
Premium-Grade Materials And Thorough TestingThe whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect. |

± 0.02 mm Manufacturing Guaranteed PrecisionPrusa Research believes the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, they guarantee ±0.02mm precision and highly-consistent colors in their filaments. |
High Quality You Can Check YourselfPrusa Research is the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool). |

About PVB
Polyvinyl butyral (PVB) is a design material suitable for easy smoothing with isopropyl alcohol (IPA). Print settings are similar to PLA, mechanical properties are slightly better (similar to CPE or PETG). Thanks to the IPA smoothing it’s optimal for printing visual models, such as unconventional vases, jewelry, lampshades, and other design parts. It’s good to tweak print settings, especially layer height, number of perimeters, and infill density. We recommend printing with a large nozzle diameter and spiral vase mode.
Main PVB disadvantages are its low-temperature resistance (approx. 60°C) and layer to layer adhesion which are similar to PLA.
Concerning the great printability (similar to PLA), PVB is a great material for experienced and new 3D printer users that would like to try something new.
| Nozzle | 215 °C |
| Heatbed | 75 °C |
| Positive Values | Negative Values |
| + Ideal for design parts, vases, lamp shades etc. + IPA chemical smoothing + Great surface adhesion + Good mechanical properties (similar to CPE/PETG) + Low warping (lower than PLA) |
- Low temperature resistance - Hygroscopic filament (absorbs moisture) - Low layer to layer adhesion (slightly worse than PLA) |
