PolySmooth & Polysher – 3D Prints Without Layers

Improve the surface quality of 3D printed parts with PolySmooth PVB and Polysher. This is an entirely new kind of 3D printing filament easy to print and a desktop machine which will bring your 3d printed parts alive. The core of the technology is the material used – PolySmooth PVB. It gives excellent printing characteristics, balanced mechanical properties, and “polyshability” when exposed to common alcohols such as isopropyl alcohol or ethanol.  The polyshing process involves exposing a 3D printed part of PolySmooth PVB to an aerosol (a suspension of micro-sized droplets) of alcohol. The aerosol is generated by a unit called the nebulizer, which consists of a thin membrane with hundreds of tiny (< 10 microns) holes, attached to a piezoelectric actuator. When actuated, the nebulizer will generate a fine aerosol of micro-sized alcohol droplets, which will then adsorb onto the surface of the 3D printed part and eventually make it smooth. Everything is done seamlessly and effortlessly in the Polysher. 3D printed goods won’t look the same anymore. PolySmooth is just the beginning of their line of polyshable materials. Wait till they come up with more exotic polyshable materials soon.

I appreciate, cause I found just what I was looking for. You have ended my four day long hunt! God Bless you man. Have a nice day. Bye

@Bernard, We have been emailing you for some time now. Please, can you check your messages.
Bernard Sia
Wtf is wrong with you people.
Bernard Sia
I still have not received mine. Email sent with no replies?
@Derek, Craig and Khopfa, we have sent you a private message with more information about your rewards
Khopfa Chanpensri
I never received mine.
Craig Schertz
I never received mine either. ?
Derek Matthew Carter
i never received lost :/
Hi polymaker, I was thinking of upgrading to a dual extruder for those dissolvable supports. Will it work well with the polysmooth plastic & polyshyer machine? Thanks, Kelly
David Siegfried
Contact Polymaker for a replacement nebulizer.
Jochem Tax
I have the same problem as David Siegfried. I used the polysher about 4 times. I love the reaults it give tho! Its a shame that the nebulizer seems to stop working. Havent been able to use it much. I just got a new printer. And ive one been able to polish 3 to 4 models.
Christopher: Yes it exists and it's awesome
Christopher Bolton
Does the Polysher even exist, or is it like vapor ware?
Christopher Bolton
Still no Polysher.....
Tom Gray
I received my Polysher some time ago but had to leave it in the box. This week I opened it and got it going. Works well, and is actually pretty in action, a wonderful combination of functionality and aesthetics.
Christopher Bolton
Still no communications and no updates on delivery of rewards.
@Francesco We have been working on improving the nebulizer output and life cycle. We are planning to launch the new nebulizers at the end of November. We will notify all users when this is available.
@Sentosa, PolyBox™ is now available to purchase worldwide, you can find it on on Amazon in the US, and through channel partners in other regions of the world. @Francesco You can use any desiccant you wish, we provide 4 x 100g bags of Silica Gel desiccant as this is can be dried and reused.
John Kocurek
Well, I hope the Polybox actually ships, unlike my Polysher...
How can we order new diffusers?
Polybox is nice, pity I could not see it at the makerfaire. Only thing unclear is what sort of desiccant bags do we need?
Sentosa Kusuma Wijaya
Will the polybox run on kickstarter?
Richard Horne - @RichRap3D
Hi Polymaker - are you showing the PolyBox at the TCTShow in Birmingham UK next week?
Tom Paulussen
@Polymaker: What exactly is the polybox?
@Peter, Yes we are very close, the PolyBox™ will be available at the end of this month.
Are you any closer to launching the PolyBox?
Bernard Sia
Hi I'll like to check on my unit. Paid $80 for shipping and nothing.
@Bruce, Please can you reply to your private messages, we are waiting for your decision.
Bruce Neckritz
Where is my Polysher? I backed this in May of 2016. So far, nothing. i am getting skeptical about this whole thing.
@Cameron @John Kocurek we will message you privately to locate your rewards.
@Simon Rafferty, Happy to hear you are getting good results. With larger models, it's quite important to check they can rotate freely and that they are centered well on the platform. If a model is heavier on one side it may cause some friction between the turntable and the platform gantry as the platform rotates.
John Kocurek
I bid on a Polysher and several spools of filament. I got the filament, but never got the Polysher. I am backer 732.
Hello, I am wondering if the Polysher units have all been shipped yet? I pledged over $400 into this and I have not even received a message or email about it. Can anybody help? Thanks,
Simon Rafferty
Thank you Polymaker - my polysher finally turned up this week.
First run went great and produced a result I was delighted with.
However since then, I've had a small issue - the turntable gets a bit stuck. It rotates at normal speed for 270 deg then VERY slowly for the remaining 90. On the last run, it stopped, leaving one side of the print virtually unsmoothed and the other totally melted! Annoying wasting 17 hours of print time. There's nothing obviously out of alignment and the turntable underneath the platform rotates fine. Any ideas?
@Jana Johnson, I have sent you a private message. We are having some issues with the tracking numbers that our warehouse are providing us. We working now to track down your rewards and get them delivered to you. Sorry for the long delays.
Jana Johnson
R E F U N D, it's not hard. Send me my money back via PayPal or send me my Polysher. I'm super offended by the fact that you're selling the units on Amazon before all your backers receive their units.
Jana Johnson
You know what, just send me a refund: 5/02/2017 - Tuesday 11:34 am Shipment information sent to FedEx You gave be a bogus tracking number over two months ago give me a refund.
Jana Johnson
Has mine been shipped yet? I'm getting really tired of this rediculous wait. Either give me a tracking number or a refund.
@Christopher Bolton, I have sent you a personal message.
Christopher Bolton
When does the shipment for the Estimated October 2016 pledges get shipped?
@Simon Rafferty, We apologize for the delay, we will take care of your shipment with the upmost urgency.
@David Siegfried & StormShadow, Please email: and they will ship you a replacement nebulizer.
@Polymaker I will email customer support. It appears one of the two nebulizers is bad. I switched to the other one and within 30 - 60 seconds I get a huge cloud of fog in the chamber. The first nebulizer doesn't vaporize the alcohol quickly or correctly it seems but the second one works very well. Now I can polish my prints in 10 - 15 minutes. Thank you.
Simon Rafferty
Still not received mine. We had a conversation by email asking for my invoice which I sent a few weeks ago and heard nothing since.
I don't understand why I needed to send you an invoice that you sent me in the first place?
David Siegfried
I used my Polysher 3 times. On the third time, all it does now is beeps 4 times and then stops.
No fog is coming out of the nebulizer.
I unplugged it and after a few tries I got it to work but it stopped early. It either stops before it is supposed to or it won't produce fog at all.
@StormShadow, If you need any technical support, please email: and they will help resolve your issue.
ross placing
@Storm Shadow, my polysher manages to generate a fog in about 5 min, and usually polysh for about 30-45 min then air dry the object in a fan draft for about 2 hours or more and I am using 99.9% isopropyl alcohol, also see some condensation on the inside of the polysher
Actually while looking at some videos on YouTube, I am not wondering if my Polysher is creating the right amount of fog. Some videos like this one seem to show a cloud rapidly forming in the machine:… I definitely can see the "smoke" of vaporized gas coming from the nebulizer but I don't ever get the foggy look you see in that video. Am I doing something wrong?
How long are people running a typical print? I have run them for a long time and the prints get polished but not as much as I expected. I am using 99% isopropyl alcohol. The Polysher generates a nice amount of fog (at least I think it does) and I can see the alcohol condensing all over the chamber but I don't get a super polished part even when I max out the polishing time (turn the dial all the way).
@Derek Kirkendall, Thank you for taking the time and sharing your knowledge with the community. We urge all our backers to share as much experience as possible so we can all make the most out our machines. For those who haven't already seen Derek's angled platform, you can download here: This is a brilliant solution for an all round polish on vertical surfaces.
@FlippinJax, I will look into your shipment history and reply to you on a private message.
@Stephen & Ross. Polished parts will fully harden given enough time and can be used in mechanical applications. PolySmooth surface will stay soft for 24-48 hours to the point where it can still be imprinted with a fingernail. It will then continue to harden over the next 120 hours to the point where it can no longer be scratched easily. This process can be sped up by air drying your parts as Ross has mentioned.
