PVB is a type of filament designed for post-processing and removal of layer lines to achieve a very smooth surface with the Isopropanol. You can spray or dip the print depending on the effect you want for a smooth surface.
ABS is a thermoplastic which is produced by the polymerization of acrylonitrile, butadiene, and styrene. It is commonly used in multiple sector, including LEGO pieces. Until PLA appeared, ABS had been the leader material in 3D printing.
You will like this filament because of how easy it is to use: low printing temperatures without warping and very easy to manipulate in order to improve the surface finish. It is harder than PLA. Ideal for those who are engaged in the fields of art, architecture, ethics, if they make models, restorations, imitations of sculptures, etc.
