Mike, do you have plans yet to sell vats with the new glass already installed? Just wondering if you plan to work something out with the creator so folks can buy new vats with the magic glass already installed rather than having a vat converted.

Had some pieces stick pretty good, but the glass suffered no damage So far.
This would have ripped up my pdms.

This isn't about the vat, which we unfortunately never got to try. The warning is about the vat upgrade service itself. We sent two vats to Evert for the upgrade after contacting him via e-mail. We were assured a rapid turn-around so mailed them in along with PayPal payment and then he just disappeared. We eventually heard back weeks later after many attempts to contact him via e-mail and phone, and he claimed that the upgrade could not be performed because the vats were the plastic version. He also claimed that he had recommended only performing the upgrade on the aluminum vats, but that was easily debunked by searching our e-mail thread. Luckily the payment was eligible for PayPal's buyer protection; however, the vats themselves were never returned. So now our b9 is temporarily unusable and we have to spend almost $200 to replace them and get the printer back up. Doesn't sound like a lot but it's as a small volunteer run non-profit that's a hit to our tiny budget, morale and general trust in the online printing community. As always, buyer beware!!

I'm very sorry to hear of your recent experience.
I've worked with Every for over five years on jewelry projects and for the two plus years I've been printing with a B9.
He is very conscientious and honest as the day is long.
When I was visiting him last week, he told me of his concern about converting the new light weight poly vat. He chose to trust his judgement and not make money and sell you a mistake. I am sorry to hear about the miscommunication and confusion surrounding this. Perhaps if you buy a Kat Vat, which is easy to convert, you can experience the advantages of the NuVat.
I started printing with the NuVat in June, 2014, months before it was available through this Forum. I'd lost 4-5 poly vats due to breakdowns in PDMS. Sometimes well into an 18-30 hour print. My workflow was severely impacted. Not to mention the hundreds and hundreds of dollars in vats and PDMS kits down the drain. I haven't used PDMS for production since June, 2014.
Since converting to Nuvats (I have two Kat Vats and one B9 Red Alum. vat) I've lost no vats to release layer failure, no prints fail due to release layer failure, no PDMS costs and no down time
with recoating. That is the workflow I need as I often print 12-18 hours a day per machine, 6-7 days a week with two machines. Sometimes, its 24/7. No way I could do that with three vats and PDMS.
The last time I used PDMS was when I bought the Red Vat. It came pre coated. It lasted less than
3 days. A single NuVat can last 4-6 months with my printing schedule.
A handy trick is to rub a drop of 10W-40 oil onto the print area before each print. This helps with the release of the first build layers with extended exposure time. After that, its the same as PDMS for my models. Emphasis on "for my models". I only print jewelry of my design and they do not cover so much of the image area as to create a release problem.
The NuVat saves me time, money and anxiety.
Maybe consider buying a Kat Vat and having it converted.
Good luck with your printing.
