Style: Saturn 4 Ultra 12K
Overall I'm happy with the Saturn 4 Ultra. My Saturn 3 ultra started having some issues after running pretty much non stop for a bit over a year, so needed a replacement and decided to get the Saturn 4 since it hadn't been released yet when I bought the 3. However, my Saturn 3 had the 12k screen, so between the 3 12k and the 4 12k, virtually no difference in print quality, which is expected. As for the features unique to the 4, I was apprehensive about the moving tank but it works surprisingly well. I had the vroom settings on my Saturn 3, so it was already printing much faster than standard settings, but while the Saturn 4 doesn't have as much control over speed (at least in lychee there's no retract and return speed adjustments for the Saturn 4, likely due to the moving tank), having said that, it actually prints a little faster than the 3 did even with the hyped up settings. And surprisingly there's no layer mark lines from the moving tank, it looks just as smooth up the z axis as the 3. That is actually fairly impressive. The auto leveling build plate was also something I was a bit concerned about. I wasn't quite sure how it worked until I actually saw how it is built and watched it go through its leveling process. But again, it seems to work well. I will say they need to add handles to the build plate since it's a little difficult to hold onto. But there are some handles shared on thingiverse that work well, so not a big deal. The clamp to hold the build plate is a very welcome improvement over the screw/knob on previous versions. However, I wish they would have added a hanger of some sort to allow it to drip at an angle for a while before removing it completely. Thingiverse has some tilted mounts for it but I haven't tried them yet. Another welcome feature is the lifting lid, but it would have been nice if they added a handle of some sort on it. Again, handles are available on thingiverse so not a big deal, but still. It is a really nice feature though. And lastly, the spill/drip tray is certainly an after-thought as others have mentioned. It works, and it's relatively easy to clean. However, it's just a thin stamped (vacuum formed?) plastic that feels like one of those disposable plastic trays that restaurants use for to-go orders. But whatever, it works. And, again, thingiverse has some drip trays that can be printed but I haven't tried those yet either. Is it worth the price difference to the Saturn 3 ultra 12k? Eh, yeah I think so. The convenience of the lid, auto leveling, etc does save some time and helps to keep the machine clean. However, the Saturn 3 ultra 12k will get you the same print results and because it doesn't have the moving tank and auto leveling build plate, you get more z axis height with the 3 model. So, the 3 is not as convenient, but it's just as capable as the 4. I guess take that for what it's worth. I'm happy with it though.

This is my first personal resin 3D printer, and overall I’m very satisfied with the Elegoo Saturn 4 Ultra. The learning experience has been enjoyable, even though I can’t compare it to other printers yet. I’ve printed a lot of test models while dialing in exposure settings for Elegoo Upgraded 8K Standard Resin. Living in a relatively warm climate, resin viscosity and temperature definitely affect results, so calibration took time. I experienced a fair number of failed prints at the start, including parts sticking too well to the build plate, but that was mostly due to my own learning curve rather than the machine itself. Once settings improved, the printer delivered excellent detail and consistent performance. Overall, it’s a powerful, high-quality printer that’s great even for beginners—as long as you’re willing to learn and experiment.

I had almost given up on resin printing because of how much mess and frustration I had been having with previous printers. I am so glad I decided to give Elegoo a chance and I am now a loyalist! They had better stay in business for ever because I don't know if I will be willing to give any other companies a chance after seeing how easy life can be with Elegoo

These machines are the worst. In 3 months, I have owned 2 of these machines and they're operated for a total of 30 days each MAYBE. I've had print screens burn out, I've had failures on both motherboards, I've had issues with the front touch panel LCDs go out twice. These are made with terrible quality parts and keeping them running has cost me more than they're worth. Support is borderline worthless, you might go 1-2 weeks before they agree to send you a replacement part, which in turn won't work. They don't troubleshoot effectively and the replacement parts have the same problems. On top of that, I've never had more misprints than I have on these machines. That could be a settings issue, sure, but the fact that they don't work out of the box is extremely disappointing. Definitely will not be buying again and am actively seeking ways to get my money back (although I'll never get my time back!)

Initial review: First print went great. I printed the Rook and had no problems. For my next print, I ran an overnight print with a full build plate. Came down the next morning and saw an empty build plate. Spent several hours trying to figure out what happened and finally determined I needed to vastly increase the initial layer print time (I had used the recommended settings from Siraya Tech). In this process however, I’ve learned a lot about this printer, which are poorly advertised: 1) there is no “AI detection” just timelapse and remote viewing. 2) there is no “smart” leveling, just a spring loaded build plate. 3) the optional heater works, but having any airflow in the machine causes drips to not land in the vat, but instead on the sides of the machine. Hopefully, this won’t result in drips going into the control systems. 4) attempting to register the printer with the app failed entirely. The app reported no serial number found. I’ll update this review over the next few days if any of the above items resolve or improve. The dimensions of the machine are great, and when it works, it prints quickly with extremely high precision. At the end of the day, this is probably a great machine, but the expectation set by the advertising and the lack of follow through on their phone app result in a poor first experience. Update 02.21.2026: Moving the star rating from 3 to 4 to reflect the reliable, excellent printing I've had since my initial review. The hot air blow causes dripping, but it is minor and easily cleaned up.
