Polymaker PolySmooth PVB 3D Printer Filament 1.75mm Beige - 750g Cardboard Spool | Easy Post-Processing with IPA Alcohol | Compatible with Polysher | Ideal for Smoothing Prints, Prototyping & Cosplay Props

I saw this and the Polysher on 3D Printer Nerd's YouTube channel about a week ago, and thought I'd give it a try. I do a lot of 3D prints that I intend to apply a paint finish to. In the past I've been known to spend 40 hours sanding (well, priming, sanding, rar) a print. This is about twice what I normally pay, but the time savings from less sanding are definitely a consideration in my purchase.Edit 6/24/17: This stuff is a game changer when paired with the Polymaker Polysher unit. The results are stunning. It's a VERY delicate filament that is more sensitive than any others I've dealt with though. Any humidity whatsoever will ruin this filament, so I keep them in sealed air-tight containers with fresh desiccant packets which are housed inside a gasket sealed closet with a dehumidifier running constantly. As long as you can store it properly it will turn out beautifully after a 30-ish minute session in the Polysher with 99% isopropyl alcohol.Another thing to be aware of (and this is something that Polymaker confirmed with me) is that this filament is only meant for organic shaped items, meaning the dissolving filament is meant to run over rounded surfaces. If you intend to smooth something that has flat surfaces and hard edges it will not smooth those, and will leave a subtle imprint of the infill beneath.5/5. So worth it once you figure it out!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 2017So 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.I used the same settings as my polylite filament and got amazing results. To smooth, you can use 91% isopropyl alcohol and give a light coat with a foam brush then let dry and repeat as many times as you want. Try not to touch the plastic before its dry or it will leave a mark. Keep your parts away from water before you smooth it, and wait until completely dry before water exposure. It is definetly a high quality material but shouldnt be used as main material as it is much more costly than regular pla/petg/abs. 10/10 Will buy againNonostante il prezzo relativamente elevato ho riscontrato problemi di adesione piuttosto importanti. Poi dovendo fondere il modello prodotto per ottenere un stampo di fusione ho riscontrato che al termine sono comunque rimasti dei residui non totalmente evaporati (temperatura di circa 750 gradi.
