ELEGOO Saturn 3 UItra MSLA 3D Printer, 10-Inch 12K Mono LCD, Powerful Linux System, High-Speed Wifi Transfer, 4-Inch IPS Touch Screen, Large Printing Size of 8.61x4.83x10.23Inch

I started 3d printing back during COVID with a cheap £99 filament printer (which quite quickly died!). I then progressed to a proper filament printer and then to the Elegoo Mars (which I loved). I found myself wanting to print larger items and bought an Elegoo Saturn. This machine blew my mind. I ran both resin printers for just over 3 years before their screens died and it became too expensive to repair. A friend recommended the Elegoo Saturn 3 Ultra and after watching a couple of reviews and doing a bit of reading, I took the plunge. I could not be happier. The machine is simple to level (and I have only done it once so far). The quality of the prints is simply superb and with its built in filter, the smell associated with resin printers is almost a thing of the past. The fact I can send prints via WiFi and not have to mess around with USB is also a good feature. (Just remember to delete your old files from the printer) All in all I can’t find fault with the machine. Good stuff. Keep it going Elegoo!

I have two of this printers. They are very good machines. The build quality is quite good, nothing to complain about it. I'm printing a lot of parts in one go and so far I have 100% success in 2k parts. The provided tools are pretty good too, the spatula works well and is sharp. I have another resin printers and I had to sharp the spatulas in order to use them. Allen keys are good quality too and it comes with some spare screws. A+ packaging. In terms of the speed, as a mono. It is 2x a regular LCD printer. The bed is very good and the leveling levelling easy but I use the method with the resin vat on. Using the paper result in the bed being too close to the MLCD.

Amazon Black Friday, yippee! After spending six months building a rotary axis CNC machine, I decided to reward myself with a 3D resin printer. First, let me say this the only one star review that I’ve ever given. Moreover, every aspect, even if seemingly irrelevant, may help you understand what I can only describe as the curse of Saturn (Satan?). So back to Black Friday, order placed, Elegoo Saturn arrival scheduled for Sunday. Well, Sunday came and went, but after no delivery by Tuesday I began tracking the order being delivered by Hermes. It had been picked up but hadn’t moved. Many, many calls, emails, and a message saying they tried to deliver it, but I wasn’t in, I learned it was still in a Hermes warehouse. But, a polite rant or two, later on the twelfth evening, my beaming wife shouted ‘come here’, so grudgingly I went downstairs, she opened the door and there it was! In fact, it had been left, without a door knock, for an hour before she accidentally discovered it. Notwithstanding, the fact that the large, slightly dishevelled box, amply describing its contents, hadn’t been pinched, it was mine, all mine! Now, I’m not one to give bad Amazon reviews for poor delivery, per se, but my 3D printing journey hadn’t got off to a good start. So, with the holiday approaching, I resolved to tackle it with a fresh heart and unbox it after Christmas. And so I did, with an intermission for decorating the kitchen and making space for this wonder machine. So now I’ll proceed to the bits you will probably have been waiting for. Upon unboxing I found the Saturn to be very well packaged, lots of foam, plastic wrap and tape. And what a beast! Sturdy, lots of metal, no scratches, but wait, what’s this? The back left foot was snapped in half while the useless remains of its sibling cowered in a corner of packaging. Aha! No worries, I can print another! Let’s make hay! Setting up was easy, despite the illegible figures in the instruction booklet. For certain, those days of watching Saturn reviews on Youtube had paid off. Next step, power on – everything lit up, it was alive! But, (you knew there’d be a but), the top of the leadscrew rod was precessing around it’s central axis like the moon around the earth. Well, maybe that’s an exaggeration, but it was noticeable. Now I know my NEMAs from my leadscrews, and this was a concern. Unlike the Elegoo Mars, which has a top bearing, the Saturn just has its leadscrew pointing up at the stars. Consequently, the bottom motor bearings have to carry all the downward forces, notably the weight of the leadscrew, the build platform, the model and the pull of release from the FEP. Why, Elegoo, why? More important would this obvious design flaw matter? After all, so long as the leadscrew drives the platform up and down accurately between two excellent linear guides, who cares? Well, in situations like this, the proof of the pudding is in the eating. I was able to move the platform up and down flawlessly, with no hint of it wobbling, phew! Next day was test day. I homed and calibrated the machine, loaded a thin test model, and let the magic happen. Now I’ve learned that hearing is the best sensory organ for a smooth-running machine and what beautiful sounds, the quiet hum of the fans and motor components, the little pops as the emergent model was raised and lowered on and off the FEP, wonderful! And once complete, a truly magnificent, highly detailed, perfect calibration model. Well done Elegoo! Mightily encouraged, the real work could now begin. I loaded sliced models of a small 5cm tall sugar cat, not essential, but cute, and a Prusa-style knob for my 4th axis CNC machine. The anticipated time was only 2.5 hours, so I lay back and listened to the soporific hums. And then the curse returned. About halfway through this second run, I noticed the rhythm now included an extra slight pop of the FEP, lovely, I thought, it must be growing nicely. But a few minutes later the new rhythm was replaced by a sudden crackling as of crumpling cellophane, a lull, another crackle, and two pops. I hurled myself towards the machine, fearing, mostly, resin seeping through a damaged FEP. I hit pause, but no leaks were evident. But I couldn’t raise the build plate via the interface. Oh well, I thought, just going to have to abort, diagnose, reset and restart, what’s a bit of wasted resin? But no, unlike my hair, the bed wasn’t rising. I gently raised the bed from the resin, pulled it out, removed the resin tray and did the only thing possible – unplug the machine and get on the interweb. And there, amongst the dunghill of useless comments and ‘helpful’ suggestions I found two nuggets of gold. The good news was that two separate Youtube videos described my Saturn’s problem (although they didn’t mention snaps, crackles and pops). Weirdly, one described how his machine also arrived with a broken back left foot. The bad news – they both sent their machines back. Now I’m pretty handy with robotic machines so I figured I could fix this. But then I realised it was likely a blown motor driver, and the question emerged why? Now bearing in mind I’d bought this accursed machine as a reward to myself after several months of NEMA controller hell, re-treading those stony steps wasn’t an option. Fortunately, I’d kept the packaging and next day I dropped it off for delivery by the courier – ironically, Hermes - to Amazon. I shall track it closely. I’m now blessed with a beheaded cat, half a knob and facing the dilemmas of whether this was a one off, or are these Saturns and other mid-price resin printers cursed? The one star is for Amazon’s excellent returns policy.

This is my first printer, very easy set up, initially had issues with prints not sticking to the base, but after a little research, problem solved.

Great printer. Had to tweak some of the settings in the slicer software but now print quality is detailed and consistent.

I am completely sold on the details of this printer, and with the extra Z height. 10/10

Great work horse. Takes a bit of time to master. Be patient and follow YouTube guides.

It has large build plate sufficient for printing large stuffs, Very easy to setup and comes with purifier which is extremely imp for resin printing.

My first resin printer was Photon Mono X and it came with a bent build plate and I never got it to work. Then I got Mars 2 Pro and I loved it and decided to buy something bigger. I was reluctant to make the same mistake as before and buy a freshly released printer (Saturn 4), so I got this one instead. It's stupidly fast and prints with stunning resolution, actually achieving that 30micron resolution in Elegoo Water Washable resin - just look at that horse symbol that was filled with black paint! This machine will definitely second as a perfect tool to make litography in metal and circuit boards! I use Lychee slicer and to my great relief I was able to get this machine to work at the first try. Third print I tried fills nearly the entire build plate and it comes out beautifully without any issues. I can only recommend this machine!

En su dia, de las mejores, hoy dia,sigue estando bien

Hay que usarla muy bien, pero el resultado es increíble

After 2 years I can say, that the Saturn 2 really holds up. So much that I still cannot justify an upgrade, no matter how much I want. It is easy to handle and a great starter printer.
