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 thing is an absolute tank! The detail of the prints, and the size of the build plate are the key takeaways for this product. However, there are some software hiccups that need updated to make it perfect. For example, if you are transferring via wifi and your computer goes to sleep or locks, it will freeze the printer and stop the print. There are also issues with the software freezing and needed to reset the machine constantly. Other than that, I couldn't recommend this machine more!

On January 31, 2025 I paid $474.98 for the Saturn 4 Ultra (12k). I didn't get it opened and set up until around the end of February. I almost wrote an amazing review. I thought this was the best 3D printer I ever used. (I have 9 others) As of August 12th, 2025 (about 7 months later) after only printing a dozen times or so, the LCD screen went out. I contacted Elegoo directly and they told me there is nothing they can do. The warranty for the LCD screen only lasts 90 days. Upon further research, I find that many people that bought this same 3D printer have had the exact same issue and had to replace their LCD screen once and some had to replace theirs twice within the first year of use. I have a total of 10 3D printers and this is the ONLY ONE I have had to replace the LCD screen on, and most of my 3D printers are at least 2 or 3 years old. The fact that this LCD screen goes out so easily and so frequently, and they only cover it for 90 days is horrifying. I would have expected at least a 1 year warranty, but that's just my sense of logic. If a company won't stand behind their products within the first year of purchase, it's a waste of time and money. The worst part is, we were planning to replace the other 9 printers with these until this happened. Now I've had to pay over $200 more to purchase a new LCD screen and hope that I can figure out how to replace it correctly. Needless to say we will not be replacing any more 3D printers with this one. Make sure to do your due diligence before purchasing. Also, Elegoo does not have a phone number for customer service. They only assist you via email. I'm not even sure how to process that... but then again, they don't stand behind their products anyway, so what's the point in customer service?

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.

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.

This is my first resin printer. Once you get a calibrated and dialed in for your resin it's amazing. Disregard the auto leveling feature to an extent because you will still have to manually level the machine itself so that your build plate is level. Pay close attention to the rubber feet they put on the bottom of the machine at the factory; mine were not even. The front left was about 1/32nd higher than the other three feet meaning the machine could rock if it wasn't shimmed. Also do yourself a favor and buy a fermentation heating band for your resinvat, route the cord up through the top out the back of the drop-down cover make sure it does not interfere with your Z tower. I recommended enclosure with a fan to suck fumes out of your living space or workspace. Keep your build plate clean, keep it warm with an elegoo heater if necessary, and if you have trouble with prints not sticking to the plate you can always lightly sand it with some 120 Grit sandpaper. Your first five or six print jobs might not go as you expect but as you dial in the parameters for your specific resin and environment you will learn to love this thing. I especially love that I don't have to give Games Workshop anymore money. Example image included of a model I printed last night at 25 um

This printer has a lot going for it, but there are some issues (plus, I think I got a lemon, which added more issues). The good: When it prints, it prints fast, and the X/Y resolution is stunning Wifi, UI and overall look and feel are very good Getting a print is pretty easy. I had the first set of calibration objects about 2 hours after the package was dropped of Overall, the machine has a lot going for it, and seems to be a decent step forward from my old Saturn 2. The bad (systemic): Anti Aliasing outright doesn't work Self-leveling is not self leveling. It's basically self-jamming-of-spring-loaded-build-plate into the first few layers. As fo the latest firmware Elegoo added a manual leveling option that is at best half-baked and not documented. The two-story build plate is very hard and annoying to clean. The AI camera seems to be rather useless. I've had objects fall off the front right corner, and the camera ignored the failures and kept on printing (the missing object was clearly visible) The bad (my machine): Front right quadrant has persistent failures. Almost every print has either de-laminations, or just fails to stick to the build plate. I've tried 4 different resins, have a chamber heater, etc. The same models work just fine anywhere else on the build plate Every few prints the exposure gets weird. I.e. the file will print perfectly fine (minus the front corner issue), and then randomly be seriously under-exposed The printer randomly rebooted four times in as many days in the middle of the print. No errors; just does a power cycle randomly. Overall, I really wanted to like this printer. It check all of the check boxes for my needs (I'm running a small business and need to print custom connector housings, inserts, and light pipes), but the rough edges made me return the printer. Still looking for a comparable alternative.
