12K Saturn 4 Ultra Resin 3D Printer, 150mm/h High Speed Printing

I gave it -1 star because of that when i bought it, there was no 16k version available here, so i had to order this one ( that doesnt have light for the camera and no heating build plate ) The other -1 star is because after 2 days of buying it, 20% discount came and i feel that i was scammed with the price because of that, i tried to solve this with customer support, but sadly nothing I wish it had a handle to lift the cover and i wish it had a different extra holder so you tilt the build plate so it drips the extra resin. Other than this the machine is great and works perfectly, fast and i trust it and i sleep while its printing, but consider getting screen protector just in case. Edit : Elegoo was very thoughtful and helpful with the issue is had, changed from 3 stars to 5 stars as they solved all my concerns

This is not my first Elegoo printer. Had good experience with their customer service which encouraged me to go for the S4U. This guy is a game changer! The struggle of hobbyist resin printer is leveling and speed. Elegoo addressed both with innovations at relatively affordable cost. The leveling is a smart idea based on springs to ensure the bed is always parallel to the LCD, it's not really auto leveling but it's smart and it works! The moving bed allows smooth detaching and so the build plate does not have to go up and down. Result: almost 50% reduction in printing time. Another interesting feature is resin calibration that aloows to dial up to 8 exposures in one shot. Wifi connectivity, camera for monitoring the print and doing time lapse... So many features at once. If you hesitate between the ultra version and the regular, go for the ultra, the added value is way above the price difference. Saw some reviews saying the printer is used, Elegoo says in their manual that they do functional test on all their printers, so could be the reason of such reviews (mine has the plastic wrap somehow looking removed and put back, but the sealing of the screen, fep and build plate were untouched).

Not working perfect I need customer service

Came dented and then they refused to change it. Also it was creating a thin sheet of print every time in the bed. contacted costumer service all their solutions didn’t work and still they refuse to admit that the printer is faulty and replace it.

Muy buena impresora, robusta y a un excelente precio, fácil de usar

Impressora muito boa, as peças saem com detalhes incríveis. O único problema é que a “peel force” é muito forte, de vez em quando danificando algumas peças.

⭐⭐⭐⭐⭐ I’ve used several resin printers, and the Saturn 4 Ultra 12K has been one of the better ones I’ve owned. Print quality is excellent, especially on miniatures and detailed parts. Fine details come out sharp, and the larger build area is a big advantage when I want to print multiple models or larger pieces at once. One of the biggest strengths is how easy it is to get consistent results once the printer is dialed in. The machine feels solid, the interface is straightforward, and print speeds are very good for a printer this size. I’ve used it for everything from miniatures to larger vehicle parts, and it handles both well. There are a few weaknesses. Resin printing still requires some setup and maintenance, and things like the release film, leveling, resin settings, and build plate setup can make a big difference. I’ve also found that accessories such as magnetic build plates can require extra adjustment. It’s not completely maintenance-free, so beginners should expect a little learning curve. Overall, the print quality, speed, and build size make the Saturn 4 Ultra 12K a very capable resin printer. For miniature painting, model building, and larger detailed prints, it has been a great machine for me.

Very good performance. I am very happy to use Saturn 4 Ultra. Its has amazing resolution for miniatures. 100% recommended

My second printer from Elegoo - larger than the previous ones, this comes with easy to understand set up instructions. Very well packaged, all aspects of the printer were very well protected for transport. The camera works very well, but make sure there is another light source otherwise it cannot take videos in pitch black. Great printer, faster than the previous generation and easy to use.
