Prusament PVB - 500gr
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.
