Prusament PVB 1.75mm Filament

Prusament PVB is Prusa's own in-house made filament. The whole manufacturing process is closely monitored and tested - guaranteeing ±0.03mm precision (± 0,03 for blends) and highly-consistent coluors. You can inspect parameters of every spool made at prusament.com. Check the sample spool!

The whole manufacturing process is closely monitored and tested – string diameter, colour consistency, and mechanical properties – to make sure that every spool is perfect.

Prusa (and us!) believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.03mm precision (± 0,03 for blends) and highly-consistent colours in Prusa filaments.

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.

Notes

This PVB is made in-house by Prusa Research.

1.75 mm filament is manufactured with the precision of +- 0.03 mm

Before printing, make sure the surface of the heatbed is clean as described Prusa's 3D Printing Handbook.

To dry the filament, please follow the instructions in Prusa's article.
