What can you expect?
Prusament PVB is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.03mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com. Check the sample spool!
Manufactured In-House By Josef Prusa
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.
Premium-Grade Materials And Thorough Testing
The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
± 0.03 mm Manufacturing Guaranteed Precision
We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.03mm precision and highly-consistent colors in our filaments.
High Quality You Can Check Yourself
We are 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).

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.
Ideal for design parts, vases, lamp shades etc.
Low temperature resistance
IPA chemical smoothing
Hygroscopic filament (absorbs moisture)
Great surface adhesion
Low layer to layer adhesion (slightly worse than PLA)
Good mechanical properties (similar to CPE/PETG)
Low warping (lower than PLA)
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 in 3D Printing Handbook.To dry the filament, please follow the instructions in our article
I'd stay away from this stuff and just print with ASA (and smooth with acetone) to be honest. • First of all, it stinks to high hell, and any enclosure / filament box you put it in will stink for a few days at least. • On top of that, contrary to Prusa's smoothing guidelines for it, 70% alcohol will NOT smooth it - you need 100%. • It's also not that easy to print with, and has a kind of "gummy" texture to it, which makes printing difficult, and results in parts that aren't strong or particularly pleasant to the touch. • Finally, it's more expensive than other materials. This was my first experience with Prusament, and so I was disappointed, but I assume more of these "cons" are actually with the PVB material. I'm sure I'll have more positive experiences with Prusament PETG, which I haven't opened yet. In short, stay away from PVB... just use ASA if you want smoothing.
In order to create a catheterization simulator to be used for practice by vascular physicians, I decided that I`ll create a model of the human body's arterial system in 3D printing. To do this I use a model from MRI segmentation. The arteries should be as transparent as possible and have a hardness of about 50 SHORE A. In the first stage, I modeled part of the carotid artery to examine which material and which printing technology would give the best result. I knew from experience that FDM would not get a satisfactory result, so I tested materials in SLA technology and the results were very disappointing: - The arteries were TRANSLUSSENT and not TRANSPARENT - The arteries were too weak - The small artery I printed was very smelly and the thought of the final model, the size of a person, made me shudder. I felt very disappointed and the motivation to continue with the project plummeted. A few days later, I stumbled upon a video online describing a new material - PVB from prusa, designed for FDM 3D printing. I was skeptic but still ordered the material from PRUSA. As usual, from my experience with PRUSA, the material arrived from the Czech Republic to Israel within two days, well packaged and the box shows the production data of the material. Already in the first attempt, after treatment with IPA, the result was amazing. i have a few photos and a video showing the insertion of 0.1 mm diameter wire into an artery tube with a wall thickness of 0.9 mm. avraham brosh israel
