Description
SUNLU PVB (Polyvinyl Butyral) filament is engineered for exceptional post-processing, allowing users to achieve professional-grade finishes simply by applying isopropyl alcohol (IPA 99%). This unique property dissolves the outer shell slightly, eliminating visible layer lines and resulting in a uniformly smooth, shiny surface. It represents a significant advantage for aesthetic prototypes, art pieces, and parts requiring a high-quality visual appearance without extensive sanding.
Beyond its remarkable smoothing capabilities, SUNLU PVB filament delivers consistent print quality. With a precise 1.75mm diameter and a tight tolerance of ±0.02mm, it ensures reliable extrusion and dimensional accuracy. The material exhibits excellent bed adhesion and virtually no warping, making it compatible with most FDM 3D printers and easy to work with for both hobbyists and professionals. Its mechanical strength also extends its utility to functional components and lost casting applications.
