ELEGOOMetal Resin Tank for Saturn 3 Ultra LCD 3D Printer, ACF Release Liner Pre-Installed, with 3 Allen Wrench, Resin Vat Saturn 3 Ultra

Coming from a Formlabs printer, it's really nice to have METAL tanks with replaceable film. I'm a jewelry designer, and the castable resins really do a number on acrylic trays (cracks them). These are nicely made, sturdy, and fairly easy to replace the FEP film in about 15 minutes with a hex wrench. I was afraid that I wouldn't be able to stretch the film tight enough, but the design pretty much ensures success. Just Google "changing out FEP on Elegoo Saturn 4 Ultra tray," and there are plenty of videos. Many tanks, Elegoo! (see what I did there??)

Perfect fit. Super easy. Nice value to have 2 d and keep printing with speed and quality whil3 you change film on their. No function issues and works well.

The more tanks you have, the quicker you can switch colors, and the more colors you can have at the ready. A sheet of press-n-seal wrap will give you a good seal, and you can even change colors mid print if so inclined.

Worked for my Saturn 3 ultra when I needed a backup and was too lazy to replace the PCF on my main VAT

If your a printer on a tight schedule look no further. Super slow delivery but great overall prouduct and great to have spares

Works the same as the resin tank that came with the printer and set up is obviously simple. It comes with tools for replacing the sheet at the bottom of the vat, a lid and some replacement screws. I recommend buying a set of sheets with this. I ran about 12 larger prints with this and found that the film developed a tear.

This vat is professionally made with high grade metals. There seems to be a slight weight difference between the stock vat and this replacement vat. Which is not a bad thing, I have had zero issues with everything I order from elegoo. This vat design is one of the easier ones to use when you replace the FEP, never had an issue. I need to hurry up and knock on wood. LoL. If you serious about having a back up vat or replacing a broken vat this is well worth the money. I am fairly new to the elegoo brand and our their Saturn 3 and a Neptune 3 pro (FDM). I couldn't be happier they just work and do very well at what they are intended for. My Saturn 3's print quality shocked me the first time I used it in the 12k range, I could not believe what I was looking at. The quality of my print was on par with sideshow collectibles level of detail. Oh I forgot to mention do not throw away the top cover which is an actual vat cover for when you are not using your resin printer. This way you can leave the resin in the vat without having to empty it.

Nice to have a backup just in case. It's great it has a cover so you can cover your tray till you need to use it again.
