Polymaker - Polysher
Polymaker's Polysher is a post-processing unit that lets you polish 3D printed objects to achieve an absolutely amazing surface finish.
The Polysher uses alcoholic solutions (with concentrations of 70% or higher) such as Isopropanol or ethanol to polish the 3D printed objects. Therefore, you can't polish parts 3D printed with filaments such as ABS or PLA in the Polysher. The compatible filament – PolySmooth – is a material based on PVB, formulated specifically to combine "smoothability" and excellent printing characteristics. PolySmooth is compatible with all filament-based 3D printers (FFF) and prints under similar conditions as PLA.
