Polymakers groundbreaking smoothing machine

 The Polysher is a first of its kind 3D print post processing machine that removes layer lines from your 3D prints with Isopropyl alcohol or ethanol. The Polysher works in combination with their new PolySmooth filament and since its announcement has been one of the most talked about 3D printing products of 2016 & 2017.

The Polysher can smooth parts up to 15 cm * 18 cm (diameter * height).

Polyshed PolySmooth parts can be used for a variety of applications including: product design & production, moulds, electroplating, art & craft, computational hydrographic printing and even fun hobby Investment Casting to name a few. For a matte finish you can easily coat your polished part with a matte primer.

Note: Polymaker and 3D Tech Supplies do not recommend putting other solvents/liquids other than Isopropyl alcohol or ethanol in the Polysher! Operating the Polysher with other solvents will damage the machine and void your warranty.

Inside the Tech

In short, Polymakers smoothing technology uses Isopropyl alcohol or ethanol to smooth an alcohol soluble material like PolySmooth.

Alongisde PolySmooths balanced mechanical properties and great printing characteristics, PolySmooth has fantastic smoothing characteristics when exposed to an aerosol of alcohol.

This aerosol inside the Polysher is generated by a unit called the nebulizer. The nebulizer consists of a thin membrance with hundreds of tiny (< 10 microns) holes, attached to a piezoelectric actuator. The nebulizer generates an aerosol (a suspension of micro-sized droplets) of alcohol. These micro droplets evenly absorb onto the surface of your PolySmooth printed part, leaving behind a smooth and glossy surface. This process takes between 10 to 40 minutes depending on the size of your part and the level of smoothness you desire.

Polymaker developed PolySmooth to be a fantastic filament that has many benefits over both ABS & PLA. You can read more about PolySmooth here. Since ABS and PLA aren't soluble in alcohol they will not polish in the Polysher.
