Good printer in every detail
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 qualityNo 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.

Excelente impresora, me gustan mucho sus impresiones con muchísimo detalle, fácil de configurar. Con una area muy amplia de impresión, de excelente calidad le pongo un 9 de 10, pues el 10 sin duda se lo llevaría la saturn 4

Un equipo muy versátil, de buen tamaño y con impresiones de muy buena calidad y todo esto a un precio bastante accesible al público en general comparado a otros equipos en el mercado
