I've been 3D printing for about 4 years and I was really excited when they launched this 3D print finisher. I had always used Polymaker filaments and they are certainly top-notch. I have done both hot & cold acetone and the epoxy kits they sell online, but this Polysher looked promising. At a price tag of $300 it's certainly not inexpensive, but I have had only a few successful polishing "cycles" as the unit will usually run for between 15-20 seconds before it goes into a fault (red warning indicator illuminates) and stops pumping the alcohol vapor. Most of the time I simply push the time dial and rotate it clockwise a bit and the unit will start working again -- but this is a constant, repetitive problem! I really didn't want to leave a low rating, but due to the Polysher's high price and poor performance, I feel it's warranted. Read more

Being very intrigued with the idea that my 3D prints could be "polished", I took a chance on the Polymaker Polysher despite the low ratings it has received so far on Amazon. The Polymer Polysher arrived very well packaged, first in a outer shipping box that held Polymaker's own shipping box, inside of which is the actual PolyMaker packaging. The instructions for setting up the Polysher the first time are very informative and the only small issue was a loose heat seal along the clear plastic hood which was easily reseated. Of course, this device only works with the PolySmooth filament but the results are very impressive. The Polysher creates a very smooth and shiny result, remaining shiny after the alcohol evaporates away. You'll get better results with prints done at higher resolutions. Even low-resolution prints come out quite nice but nowhere near as nice as those done at a high resolution setting. The PolySmooth filament (sold separately but required for the Polysher to work) is not PLA and requires slightly higher temperatures than the PLA preset in my version of CURA. It was easy to setup a new profile with the necessary adjustments and the filament is working nicely creating nice prints even without the use of the Polysher. While not necessary, I would think that a heated bed would be useful to increase adhesion. My first print encountered the same problem mentioned in other reviews. The unit shut down with an error after 5 minutes of polishing. Resetting the timer and restarting the polishing process solves the problem. My second print worked straight through with no problems. I've only had the Polysher for a few days but so far I'm very impressed with the results I'm getting. If you're okay with working within the closed eco-system of Polymaker's products, the results are very good and I'm actually very enthusiastic about continuing to use this to post process my prints. I'll update my review if I encounter any problems over the next few weeks. Update: August 2017 So I've had the Polymaker Polysher for a few months now and it continues to do what it advertises and in general I've been very happy with the results. The only problems I'm encountering are the continued nebulizer halts about 5 minutes into the procedure. Sometimes it only happens once, sometimes it happens a couple of times in a row. This has the unfortunate side effect of prolonging the smoothing process and requires a bit more supervision. I find myself starting the process and waiting around for the first 5 minutes for the unit to shut off, another few minutes for the unit to evacuate the mist and then resetting the process. It usually works the second time through but there have been times I've had to restart the process more than once. Also, I'm having problems with the Polysmooth filament. Perhaps it's very susceptible to changes in the atmosphere (it is summer with its inherent increases in heat and humidity) but I'm finding it very difficult to get clean prints anymore. I do store the unused filament in the included resealable bag with a package of desicant but most prints these days don't have the look of a recently opened spool of filament. I'm getting lots of stringing or bad layer adhesion resulting in gaps. I'll have to reach out to Polymaker to see what could be done to improve my printing. Nonetheless, it's still an interesting product and I generally have had a lot of success with it. I hope that efforts are underway to improve the product and fix the various problems that have been reported. Read more

Firstly, the Polymaker Polisher and Polysmooth filament are game changing products. If you are looking to produce professional looking parts with a smooth glossy finish than this is a must have. Additionally, the Polysmooth filament prints better than any filament that I have ever used. Briefly, I own four 3D printers and print daily. Ease of use and breathtaking results make the Polymaker polisher a worthwhile investment for anyone serious about 3D Printing. Lastly, the customer service provide by Polymaker is outstanding! In fact, with the exception of Amazon I have never experience customer service like Polymaker’s. For example, I recently had to return a defective unit as the platform would not raise or lower after about 2 weeks of extensive use. After informing Polymaker of the issue they generously offered to send me a brand-new machine. However, I had already initiated the return process with Amazon so that I could purchase another Polysher. As a result, Polymaker could not send me a new machine as I had already begun the process of purchasing another one. Instead, Polymaker sent me a brand-new roll of Polysmooth filament free of charge! Even better it was the color that I have always wanted to try. Their customer service is fast and responsive. I will be purchasing all of my filament exclusively from PolyMaker. So far the new Polisher has been fantastic! I will continue to post updates. Read more

Das Gerät macht was es soll. Leider macht es für den Preis keinen vertrauensvollen Eindruck. Der Tisch für das Material und die Spindel machen einen etwas "labbrigen" Eindruck. Mal abwarten, wie lange die Technik funktioniert. Read more

The unit I received works fine without problems except the fact that depending on polishing time, the parts can stay soft (you can dig your fingernail into them) for weeks after polishing. They do look nice and feel smooth though, and you can handle them in this time. I spoke to people at Polymaker about this softening issue and they recommended shorter polishing intervals (15 minutes or less, doing multiple exposures if more polishing is needed rather than one longer exposure) and then putting the part in front of a fan for a full day. That seems to work okay but it's still not great and the parts aren't fully cured for another few days. I like 3d printing because I can quickly iterate through new designs. Adding on 5 extra days of waiting time before I get to try something out is significant to me. Read more
