Polymaker offers 3D printing accessories to optimize the user experience with their filaments. The nebulizer is the core of the Polysher™, it creates the fine mist of alcohol which evenly smooth the PolySmooth™ model. ****Technology**** The Nebulizer is the core of Polymaker's Layer-Free™ technology: Layer-Free™ technology involves exposing a 3D printed part to an aerosol of micro-sized alcohol droplets, generated by a rapidly vibrating, perforated membrane called the nebulizer. The aerosol will then be adsorbed by the surface of the 3D printed part and render it smooth and layer-free. Compatible Material: PolySmooth™, PolyCast™ Polishing Liquid: Alcohol (>70%) (IPA, Ethanol) Polishing Time: 20-40 min typical (varies based on part size, alcohol concentration and ambient temp.) Operating Temperature: 15 – 32 °C (59 – 90 °F) Storage Temperature: 0 – 38 °C (32 – 100 °F)
