I bought a Mars printer (earlier smaller version) a few years ago as my entry into resin based printing having spent many years in the FDM world.This was easy to set up and get my first test print running (castle rook that came on the usb drive). The software that comes with it is easy to use if you know about slicing software already and most likely low learning curve for someone new into the space. Again, I've been using slicing software for 10+ years so it was very easy for me.It only came with one tray and cover, I recommend buying additional trays (sold here on Amazon) to make it easier to switch colors or resin types if you do a lot of that. Otherwise, one would suffice for most people printing models or figures that they plan to paint anyway. ( Usually print functional parts and gears, so I change colors or resin types a lot). Whether you purchase additional tanks or not, you will definitely want to have on hand replacement film for the tanks in the event you damage it or accidentally expose the film to UV light when cleaning the tank to change resins.Probably my only gripe is that the prints stick SO Good to the build plate, that even a sharp scraper is some work to remove them. The printer comes with a plastic scraper which is not adequate for the task. I assume they send a plastic scraper to prevent you from damaging the build plate with a metal one. But even with the scratches I've caused with a metal scraper, the plate still works just fine.I like that they moved the usb plug to the side whereas the Mars has it on the back of the printer. Easier to access for sure, would have liked it be an SD-Card slot on the front but I'm just being picky now.All in all, a good printer that produces very high detail and resolution prints that is easy to use.

It prints super good, and everything thing so far about it is great.

The media could not be loaded. Very nice machineLives up to its reputationHighly recommended when looking for quality prints. Very easy to use and quiet.

La maquina llegó en noviembre de 2024 y llego experimentando fallas en la pantalla, llego con puntos de daño de la misma y las impresiones salían mal, me comunique con Amazon y me proporcionaron el contacto del tramite de la garantía.A la fecha Elegoo segun ellos me ha enviado la pantalla para reemplazo y la misma no llega, volvieron a enviar otra pantalla y el producto siempre lo devuelven a la Guangzhou International Exchange Office.Pesimo servicio post venta por parte de Elegoo.

I did a bit of looking around before settling on this printer. In my "research" (web browsing) I came to realize that I wouldn't benefit from having an 8k printer. My eye, and apparetly others, struggle to see any real difference between most on 4k to 8k. I decided this printer had an installed userbase and the brand had a good name.I've been very pleased with the build quality, the print quality, and Elegoos support. I ended up getting resin on the inside of my cover and Elegoo was kind enough to squash my OCD by sending me a new one, free. Support was quick given the time difference and I had my new, clean cover inside of 2 weeks from China.This printer will come with most of what you need to get started if you're new. Scraper, gloves, filters, tools, everything but resin. If new to resin printing there's only a few must haves after that.I've printed quite a few different things and have had nice success. Only issues were my own mistakes in supporting or resin settings. Details are great as well, surprising at times.I suspect this will last me a bit, but if I need or want another printer I will be buying an Elegoo branded machine.

Iv bn 3d printing PACF for years but this is my 1st resin printer. I have no experience with this type of building process. Post processing is a mess, a real mess. Its not just another printer for the farm. Its totally different from FDM printers. You dont just make room for another printer, you need a complete post processing cleaning area thats 4 times the size of the printer. Once I got my head around the process the prints are far more detailed although not quite as strong with standard resin. They do make stronger resin.The gotcha I find puzzling is the build plate. I dont know if this is true with all 3d resin printers but this one is Aluminum. Thats right, soft aluminum. Removing the printed model with all its supports off the build plate is hard to do. I tried to use the included plastic scraper butt that doesnt do the job. So I used the included Stainless Steel scraper. That took it off with a little help from my hammer. It also left a pretty big gash in the aluminum build plate. I found a flex plate for $120 with shipping but they are on back order for this Saturn 2 printer. You may want to include that cost in your purchase.I say this is not for beginners because there is a lot to learn about the process. Its not just a $600 printer. I easily spent over that to build and equip a safe cleaning with ventilation station. But now that its built my second Saturn 2 was just another $600 printer. lol.. It does print excellent detailed parts.

I own a 3d printing business and exclusively use Saturn 3 Ultras right now because they produce high quality prints at faster speeds than other printers. The wifi is also a must for me as dealing with dozens of USB sticks would be a nightmare.My only issue is the inconsistent quality of ACF films. Sometimes you will get a film that will last for weeks and tens of thousands of layers. Other times a film goes back in less than a week under the exact same conditions. This is an issue, along with the availability of the films, that Elegoo MUST correct if they're going to continue using ACF in their printers. Yes, you can change it to PFA or FEP, but this printer is intended to provide high print speeds, so I stay with ACF. I do not find that the print quality degrades to any significant degree versus FEP, at least not on this particular printer.

Works like a dream!
