The Polysher™ is a desktop post processing unit designed to remove layer lines from PolySmooth™ and PolyCast™ prints. The Polysher™ uses Polymaker’s Layer-Free™ technology to create a fine mist of isopropyl alcohol which evenly smooths the model.

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 with a glossy surface.

  • Information

    Professional Surface Quality - The Polysher™ is a reliable and automatic solution which improves the surface quality of 3D printed parts, achieving a professional smooth and glossy surface.

    Intuitive & Easy To Use - The Polysher™ is designed to be intuitive and easy to use, simply turn the control dial to select your polishing time and sit back. The polishing process typically takes between 20 - 40 minutes for most models.

    Safety First - The Polysher is air tight sealed so no spark can be generated inside the chamber. Polymakers Layer-Free™ technology uses a safer cold liquid-phase polishing process rather dangerous heated vapour-phase smoothing. The Polysher's lift design also ensures IPA is contained inside the chamber when removing parts while the integrated smart electronics ensure maximum safety in work and education environments.

    Detail Maintained - With Polymakers Layer-Free™ technology, the fine mist of isopropyl alcohol evenly coats the part while preserving details and dimensions.

    Low Costs - The Polysher™ is an affordable solution which requires only a very small reservoir of Isopropyl Alcohol, recycling run-off IPA for efficient and low cost polishing.


    Polymakers technology is intrinsically safer than other smoothing techniques:

    - No heating is involved

    - The nebulizer technology requires only a very small reservoir - Isopropyl Alcohol is safer than smoothing chemicals like Acetone or MEK

    - It is a liquid-phase polishing rather than vapor-phase polishing process (the latter is more dangerous for a number of reasons)


    Polymaker have also implemented a number of safety features into the machine:

    - Multiple sensors to detect any sign of malfunction of the nebulizer (e.g. running dry)

    - Chamber open/close sensor (the machine won’t start if the chamber is open, and will automatically terminate if the chamber is accidentally open during polishing)

    - All electronic components (running at very low voltages) are properly sealed, and no spark can be generated inside the chamber.


    1. 3D print your part with PolySmooth™ or PolyCast™ (sold separately), just like what you normally do with PLA;

    2. Fill the reservoir with isopropyl alcohol. (NOTE - Do not fill the reservoir with other liquids or solvents other than isopropyl alcohol or ethanol as this will damage the Polysher.)

    3. Place the printed part in the Polysher;

    4. Set the polishing time by turning the knob; a typical part takes 20 - 40 minutes, depending on the size of your part.

    5. Once polishing is finished, the platform will automatically lift up for you to easily get the part. Operating the Polysher is that easy!
