Improve the surface quality of 3D printed parts with PolySmooth PVB and Polysher. This is an entirely new kind of 3D printing filament easy to print and a desktop machine which will bring your 3d printed parts alive. The core of the technology is the material used - PolySmooth PVB. It gives excellent printing characteristics, balanced mechanical properties, and “polyshability” when exposed to common alcohols such as isopropyl alcohol or ethanol. The polyshing process involves exposing a 3D printed part of PolySmooth PVB to an aerosol (a suspension of micro-sized droplets) of alcohol. The aerosol is generated by a unit called the nebulizer, which consists of a thin membrane with hundreds of tiny (< 10 microns) holes, attached to a piezoelectric actuator. When actuated, the nebulizer will generate a fine aerosol of micro-sized alcohol droplets, which will then adsorb onto the surface of the 3D printed part and eventually make it smooth. Everything is done seamlessly and effortlessly in the Polysher. 3D printed goods won't look the same anymore. PolySmooth is just the beginning of their line of polyshable materials. Wait till they come up with more exotic polyshable materials soon.
