PolySmooth™ is a unique, easy-to-print filament designed for hands-free post processing. The surface can be smoothed with alcohol to achieve layer free models using the Polysher™.
We recommend that this material be used with the PolyBox™ and to keep it at dry conditions (relative humidity of 15% or less) at all times to maintain the best printing results.
PolySmooth™ features Polymaker's Layer-Free™ technology:
Layer-Free™ - 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.

3D printed fashion from Laura Jonas
Laura Jonas is a Czech company creating unique fashion items using PolySmooth™ and the Polysher™ to achieve a finish that is aesthetically pleasing for their jewelry range. Combining glossy plastic parts with materials more traditionally found in jewelry making, Laura Jonas has managed to create a look that is unique and beautiful.
Martin Jonas – Head Designer says “I love working with Polysmooth™ and the Polysher™, I used to spend a lot of time sanding and buffing my 3D prints to get them to the industry standard surface finish. Polysmooth™ has completely removed this process, now I can print our accessories and get repeatable results in the Polysher™ with no extra effort.”

It is no surprise that PolySmooth™ has become a popular choice for everyday printing projects, providing an easy to work with material that can be easily joined or post-processed. Available in a diverse range of colours, PolySmooth™ offers a safe alternative for users interested in post-processing their projects either manually or automatically. While materials like ABS and ASA can be chemically smoothed with their own solvent (acetone): the vapor smoothing process of ABS is hard to control and these materials have more printing requirements to consider.

PolySmooth™ offers users many post-processing possibilities. First and formost PolySmooth™ is designed to work effortlessly with Polymakers Polysher™ to deliver users an easier and safer process to remove layer-lines. The technology behind PolySmooth™ involves exposing the part to an aerosol of alcohol micro-droplets which absorb onto the surface of the PolySmooth™ print. With the Polysher™, exposure time can be easily controlled to preserve features and details.
The alcohol solubility of PolySmooth™ also offers the potential to post-process large projects manually. When manually post-processing large items. it is recommend to work in a well ventilated and dust free environment.
To provide a solution which can be used to produce real products, mechanical properties are just as important as surface quality. In addition to balanced mechanical performance, Polymakers Layer-free™ technology also offers some interesting benefits with improvements in impact resistance after polishing. It is not because of any chemical change of the material, but due simply to the fact that the surface is now smooth and free of defects. So the “ridges and valleys” from the layers prior to polishing can often act as stress concentrators, and are usually where the damage (in the form of cracks) initiates; by eliminating the layers the part becomes more damage-resistant and tougher.
The polishability and surface of PolySmooth™ offers many post-printing possibilities.
For painters and hobbyists, PolySmooth™ offers a unique solution to smooth parts without spending many hours sanding and filing. Once the surface has been polished, PolySmooth™ adheres well to a variety of paints including: Acrylic, Oil, Eggshell, Emulsion, Watercolor, Cellulose (<50% thinners, sprayed with an airbrush at 7psi) and Powder.
For users who require a smooth matte surface finish, simply coat the model with a matte spray paint after polishing.
With the ability to produce smooth 3D objects, PolySmooth™ lends itself well to hydrographic printing applications. Traditional hydrographic printing has been limited to repetitive patterns as it is almost impossible to line up models with details on the print. Now using software developed by Prof. Zhou's lab, Prof. Zhou has been able to turn a 3D surface into a 2D map and using a conventional 2D printer and a PVA film; controlling with a very high degree of accuracy exactly where the print will go onto the surface.
The smooth, layer-free surface (after polishing) greatly facilitates the hydrographic printing process and the PolySmooth™ bonds strongly to the ink, without any need of surface treatment prior to hydrographic printing. By combining the two technologies one can easily produce high-quality, full-color products with desktop 3D printing!
PolySmooth™ also allows for easy support removal and clean up, the majority of 3D printers currently on the market are single extrusion machines, as a consequence, complex geometries that require support must use the same support material as the build material. In some cases, this can cause issues as the support can leave scarring on the interface surface where the support meets the model. Compared to other materials PolySmooth™ supports can be removed relatively easily and scarring that is caused by the support material can often times be remove once the part has been polished.
Users who own a dual extrusion 3D printer can also print PolySmooth™ with Polymakers PolyDissolve™ S1. PolyDissolve™ S1 is a dedicated support material engineered to deliver water dissolvable supports with perfect interfacing and improved part surface quality. PolyDissolve™ S1 is compatible with a wide range of material types and Polymaker filaments.

Parts printed in PolySmooth™ can be polished in Polymaker's Polysher™ which uses Polymakers 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.
Polymakers Polysher™ and Layer-Free™ 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 their Polysher™ 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.
PolySmooth™ 3D printed parts do not print with a smooth and glossy surface, this is achieved by post-processing the part. Polymakers Layer-free™ and Polysher™ technology offers a unique, safe and easy way to post-process 3D printed parts.

PolySmooth™ has been engineered with compatibility in mind to print excellently on a wide range of 3D printers.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.
Q: Is PolySmooth™ a PLA filament?
A: PolySmooth™ is neither PLA nor ABS; it is the first 3D printing material based on PVB (polyvinyl butyral), formulated/designed specifically to combine "smoothability" and excellent printing characteristics.
Q: Will Polymakers Layer-free™ technology improve the quality of my 3D prints?
A: Polymakers Layer-free™ technology is designed to improve the surface quality of 3D prints while maintaining details including textures and dimensions The best post-processing results will be achieved when PolySmooth™ has been printed with fine layer heights and no defects. If a part has been printed with defects or a rough surface finish, these defects will be maintained in the same way that details are preserved. In these cases users willing to the detail of their print can over-polish the part to soften the impact of the defect.
Q: Can PolySmooth™ be printed at large scales without warping?
A: PolySmooth™ offers very similar dimensional stability to PLA and PETG and can certainly be printed at large scales without warping. When printing large objects we recommend a consistent room temperature and setting your heated bed to 70˚C. Please note while PolySmooth™ doesn't warp in most situations, printing in a cold environment or with poor first layer adhesion can cause any material to warp.
Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S1 filament is the recommended support filament for PolySmooth™. If your 3D printer is not equipped for multi-material, self-support can be used.
