PVB (Polyvinyl Butyral) is a transparent, strong and easy to print polymer. This material, after post treatment and polishing, provides excellent clarity to printed parts. Also malleable, it can be deformed without losing its strength. A printing temperature between 190 ° C and 230 ° C and a heated bed of up to 70 ° C are required. PVB is a hygroscopic material and absorbs moisture from the air, so it is important to store it in a dry place when not in use.
