Polymaker PolySmooth PVB Filament 1.75mm 0.75kg Transparent - Print Like PLA Filament, Easy Smoothable Post Process with IPA Alcohol, Work with Polysher

The media could not be loaded. I absolutely love polysmooth filament! It Prints exactly like PLA, and doesn't take anything special, just some 95%+ isopropyl to smooth it significantly. For colors, the red looks a little more orange than red, until you smooth it, and it goes back to a sort of bell pepper red. White (and red actually) is a tad translucent at only two walls thick. Grey is definitely more blue than grey. It works great in the Bambu AMS and the multicolor printing doesn't seem to bleed much, if at all, when smoothing. It's definitely my preferred filament for all finishing cosplay applications, because I can skip bondo and filler, as long as you print with at least three walls thick, it's pretty hard to sand through the layers. Joining pieces is pretty easy too, because you can make a sort of 3D gloop out of scraps of filament and some alcohol. Turn it into a paste, wipe it on and let it dry and then sand and smooth as normal! This stuff is really just a better version of ABS, as long as heat tolerance isn't your main concern (again, it melts at a normal PLA temperatures)

Used for a bronze burnout. No problems. Prints very well. Lower burnout temps than other materials and alcohol soluble really helps for printed gating and washout

There was a bit of an odd smell while printing, just enough to open a window. Otherwise, this stuff prints like PLA. After it was done printing, I used a fine mist of rubbing alcohol and in 20 minutes my print had a mirror finish using the black filament.

I read a lot of people complaining about the price but using PolySmooth has saved me so much time and effort. Still learning the behavior of the product but have successfully printed and smoothed multiple parts using my homemade alcohol vape chamber. Highly recommend if you don’t want to sand and paint.

Lead time and price,

I tried using this for support material for PLA on my prusa XL5t. I had tried a roll of tronxy pva, which started very brittle and stayed that way despite days of drying and careful storage.For the first 3 prints this PVB worked great. After that i can only get about 1/2” height into a print before the filament breaks in the extruder and stops feeding. I tried reducing the pressure on the filament to the point i could pull it backwards, with no change.This roll has either been under vacuum with 50g of new silica gel, or in my sunlu s4 at 50C since i opened the factory packaging. Hygrometer in the vacuum bag has remained at 15% the entire time.This is the first time polymaker has let me down.

I’ve printed with this spool for about a month and its now starting to get tangled causing it to not feed which then wastes product and time. It was an 11 hour print and i babysat it on the 3rd attempt till it had 5 hours left and when i woke up it looked like it tangled shortly after i stopped watching it 😞 so much time wasted

If you get this, print with it quickly. While it’s super cool and very useful that it smooths with alcohol, it only took about two weeks for this to start the problems that moist filaments have.
