ELEGOO Saturn 4 Ultra 12K Resin 3D Printer, with Smart Automatic Leveling, 10-Inch 12K Monochrome LCD, 150mm/h Faster Printing Speed,8.62 × 4.84 × 8.66 Inch Printing Size

TL;DR; I'm finding following PROS of this printer: - Faster than competitors out of box without any tuning and preparations. Just get it and print faster than competitor - Precise time estimation in chitubox. it prints roughly the same time that you see in chitubox. No huge underestimations detected by me - Overall good user experience with printing, cleaning, interacting. Might be better though. There is a room for user experience improvement. For more impressions read below. I have Anycubic M5S to compare, so my highlights based on comparison of Saturn 3 Ultra with Anycubic M5S. Below you'll find items that I like more in Saturn 3 Ultra rather than M5S having both on my table. My impression about build quality - solid build and overall good engineering. - It looks gorgeous. I keep it in enclosure box without top lid, but anyway, very nice look. - Solid metal body has handy side effect for me. I can stick something magnetic to it. In my case, it's chitu heater. Top surface where screen located is plastic - Handy resin VAT. It has handles instead of cavities (like on Anycubic). Handles allow you hold VAT much easier/stronger and that means less spills and overall less mess. Absence of cavities means that there is no resin in cavities. Less time to clean the VAT - Touch screen with good resolution and response. Good UI overall. - WiFi without pain. Just connect to your spot right from Saturn 3 Ultra screen (I didn't managed to have working WiFi on M5S). No flash required if you're using chitubox. Small, but very nice improvement for me - Ball screw. This is something affiliated by Elegoo as faster and smoother movement over the lead screw. That's exactly it. When you manually manipulating Z-axis it moves faster and smoother than Anycubic M5S. I can clearly see that by my eyes. And have suspicion that this reflects on print times. - Build plate surface. It more resistant to scratches, has two ribs in mount profile which keep plate in place (in the same place) when you releasing or tightening fixing nut at the top. - USB charcoal filter. Well, it's roughly has x3 bigger filter area than Anycubic and you have one in a box. Somebody could say "who cares, it's a toy" and probably will be right, but it's there for free and it has bigger filter surface. One drawback: it runs only when print starts. You can't have it running if you're not printing. So, enclosure post filtering is not possible with it. Now, about speed. Measurement been taken on stock profiles of Siraya Tech Emerald Blu for M5S and Saturn3 Ultra. Those profiles have different speed settings. 240 mm/min lift&retract for M5S and 320 mm/min for Saturn 3 Ultra. Which is big difference. Maybe for a good reason maybe not. Ameralabs exposure test in original size (~15mm tall). Conjure Rigid resin with Siraya tech Emerald Blu V2 stock profile for Elegoo Saturn 3 Ultra. Chitubox estimated time as 52 min print. Actual time taken - 47 min. The same model with the same resin but with Emerald Blu V2 profile for Anycubic M5s takes ~1h15m (01:14:55 or something like 01:14:5X). Сhitubox can't estimate precisely or even close. Usually, actual print time is x1.5 or more from chitubox estimate. Photon workshop gives precise estimations (which are ~ x1.5 bigger than chitubox), but I can't get used to it. Well, that's 28 min difference on a print 15mm tall on stock profiles. Guess, promised 100-150mm per hour not achievable on resin with high viscosity, but Saturn 3 Ultra clearly faster than M5S out of box without any profile tuning or preparations. Print quality No surprise here. It's good. On par with M5S when you're looking on printed model with your eyes. I'm more functional prints guy rather than miniatures, so the only high-detail prints I see is calibration tests. And results look pretty much the same for my eyes. Now, some drawbacks that I've noticed: - You have update over wifi option in UI but it does not work (says that feature does not supported). Guess, they will add this in future firmware releases but at the moment of writing with 1.4.3 firmware it does not work. - Elegoo fans producing more noise than Anycubic. It's hard for me to say whether it louder or just more unpleasant frequencies, but difference noticeable. Honestly, I don't care much about this since it sits in enclosure. - Screen might be hard/not comfortable to read. Depends on how good your eyesight. I wish it could be bigger and/or easier to read. - 4 stars "for beginners" because Anycubic autoleveling and pressure sensing that detects failed prints is hard to beat.

Right out of the box this was able to print fantastic 3d models with insane details. This is my first 3d printer and i was able to jump right in to the hobby with zero problems. The user interface was very easy to use and the included software is very easy to import 3d model files and add required supports. I thought I would have to spend more to get these results on my first attempts in the hobby but this was a great deal. I will say one thing I had to do was use a little bit of fine grit sandpaper on the build plate to get the resin to stick better, had 2 failed prints early on that weren't sticking. proper light sanding and cleaning fixed it immediately. Another helpful tip is to set your base layer exposure time to 40-45 seconds instead of the default 32 seconds. Also make sure whatever surface you are putting this on is completely flat/level or else your prints will not stick! Besides that this has been awesome to use and im addicted already. I included a picture of a an Oni mask and a small corpse mound figure. The tiny little hands of the skeleton came out perfect even, added a single match for scale :D If you're on the fence, get one! You wont be disappointed.

So far I love it. I have had a filament printer for a long time and the resin is a game changer. Both have different strengths and weaknesses but it's pretty awesome what this can do. My biggest challenge is I have a lot of flat prints and that creates suction issues that cause leveling issues, and the resin cost is significantly higher per print than filament prints. But on the plus side it prints really fast high quality detailed prints that are durable and functional and comes with software that works well with it.

Works great. Self leveling is working perfect so far. Heating option has had no problems yet. This machine works like it should. I bought another identical a week later just to double my output. Worth it! Look no further!

So, the Saturn 3 is, generally speaking, the best bang for buck printer out there. I think I elegoo would of course love to sell 4s and 4 ultras but the truth is this machine prints just as well, easier to work on, and is essentially the same sans gimmicks that the new printers have. Buy a fermentation belt and slap it on the vat and it’s 99 percent what a Saturn 16k is. I should know, have both and still come back to the Saturn 3. Here’s the problem. QC. First off none of these manufactures make any of the internals on any of these machines. All repurposed parts. And the guys of them all is basically the same. So it really comes down to QC and support. Elegoo generally better than others so we’ll see what they do here. With this most recent printer, I have gotten persistent delamination from the bed on the same corner. Re level, test and seems to be an easy fix, these build plates are always machined poorly and sanding on a flat tile does the trick. To double check, I swap and relevel a sanded build plate I had off another Saturn 3 I own. I know this is flat and just want to double check before I take the plunge. Lo and behold, still getting separation in the exact same corner on the second, sanded build plate. Then I take a closer look. The screen isn’t installed flat. Either some debris got under or it’s a defect in the bezel of the screen. Still testing. Will see if elegoo offers a solution otherwise will get it sent back and hopefully can update review then.

The printer is just not printing. At the bottom of the bed a small flat slab falls and then no printing takes place. It is impossible to contact Elegoo official to lodge a complaint

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

Can print right out of the box. (Plus after leveling). Smooth printing

Después de 1 año de uso no me dio problemas, a excepción de un error mío que hizo que la pantalla falle pero si tienes cuidado con ella jala al 100 La foto es después de un año de uso

Muito boa. De fato faz um bom trabalho. Gostei muito.
