Saturn 4 Ultra: Elegoo's Biggest Upgrade in Resin 3D Printing

Just pour resin, it prints. That was my experience with the Saturn 4 Ultra. No Z-offset, no paper strips, no screws to adjust... Resin 3D Printing is very easy now - you just focus on Slicing it right.

Thanks Elegoo for sending the Saturn 4 Ultra for me to review!

2 versions: Screws (drilling) and Adhesive (Double-Sided Tape)
Levelling the Build Plate always made me a bit nervous: like, "I need to do it right..." Otherwise you would just discover it one hour later... And Cleaning a mess before trying again was no fun.
The Saturn 4 takes out most of the difficulties. It is very automatic with a bunch of sensors to help. I won't say it is impossible to mess up. But the printer finally helps a lot to avoid problems.
Sure, you still need to master the Slicing tools. And avoid making a mess with resins... and wear protection.

I love that you installed the handle. It just grinds my gears that you didn't do it on the indented other side of the front. xD

[@GeekDetour]

I see… yeah, the right side is a bit more recessed in the center. When I have time, I will make a variation of my model and I will post it too - the one at the left is already on Printables (link in the description). I usually open doors and lids with my left hand, so the main task can be made with my right hand - I didn’t even consider making the handle for the right side because of that. Also, a handle at the right side might partially block the vision of the touch display, when you are standing up and looking down to the printer. But that’s the beauty of DIY solutions: anyone can choose what’s more important and fits best your preferences. Thank you - that was eye opening.

[@Tankbrusher]

How did you test if that latching mechanism is "perfect every time", didn't see a dial test indicator - just curious because it's a feature on a part of the printer I had trouble with in the past on other machines - overall repeatability.

[@GeekDetour]

You have a point: I didn’t use a needle dial to test for tolerance between each insert. What I know is: the old mounts (the ones with the ballheads) you could feel everytime you inserted it, they would rest in different positions and the paper tests indicated that the position was slightly different. The way this one on the Saturn 4 is machined is very different than that. It rests on a completely flat surface and you feel it. Also, the springs on the build plate guarantee the contact against the screen. So, yeah, even if it has any variation, the whole system actually worked fine for me perfectly in my test prints without the usual fussing that I was so (sadly) used to do. @FauxHammer just released his review - he printed way more than I did, and his results are the same: it just prints great and easy.

Excellent question! I don’t know - I think I need to make a follow up video with questions like this. Thanks!!!

[@massymetto76]

When you cure under the Uv , what is the liquid where you'll put the piece? Water or something else ??😊

[@GeekDetour]

It is Water 💦 And it doesn’t matter if the resin was Water Washable or not - it is not for washing, the piece is washed already. It cures differently - it’s better underwater, or should I say, it cures better without oxygen? 😄 FormLabs has an article about that.

[@HouseProjections]

Thank you very much for all the information, it's made getting up and running with my Saturn 4 very enjoyable. A quick question tho. Regarding the resin calibration, how are the quadrants identified? For example, at 5:44 would your top left model in Chitubox relate to quadrant 1 seen at 5:51 with an exposure rate of 2.75s?

[@GeekDetour]

Thanks! Next week I will release a video that will show it quite clear - and I will release a model and instructions for the order on 4, 6 and 8 tests (yeah, you can have 4, 6 or 8… saw it after I released my review 🫣 look: kzbin.info1YDN2oVcC8I?si=CLPWTX62ZrloBsAO

[@HouseProjections]

@@GeekDetour Thank you! I just spend WAY too much time realizing "FRONT" in Chitubox does not mean the the edge of the build plate that faces the FRONT. The arrow and "Front" label actually designates the edge of the plate that slides onto the the handle. In otherwords, in Chitubox "Front" faces the rear. I only realized after adding tags and numbering 6 models. One failed and stuck to the film. I was able to see the numbering system. I then looked at chitubox basic which uses the build plate in the UI, where PRO just has the grid. It's VERY confusing.

[@HouseProjections]

@@GeekDetour Just a heads up. I've been having issues all day with half my build plate not sticking. Running a 6 zone calibration I only get 4 models. Tried different models, different slicers, different filaments, changed the film twice, cleaned the plate, etc. There are now a few posts on reddit and Facebook with people having similar issues.

There is something you can try about the build plate - watch my new video about the Mars 5 Ultra and how I could tune the screws on top of the build plate: kzbin.info/www/bejne/rYuVp5-Lltynptksi=hj7DB-zM1AmrOfsi

Hey thanks for the review, planning to upgrade from Saturn 2. Are you using a water-washable resin hence curing the print soaked in water? From the looks of it it is plant-based elegoo resin?

[@GeekDetour]

Excellent questions! I think the Black resin I used for the Rooks were a Black Plant-Based resin, that Elegoo doesn’t sell anymore - it was not water washable. BUT, after I clean the part in alcohol, I like to cure them submerged on water - I need to make a video about the reasons why I do it. The most important is that the part gets less tacky. 👍

But I don’t know for sure, so I need to ask them if what they sell now would accept the Saturn 4 build plate or not.

[@jerrickteh9374]

Hi there, by any chance, do you hear back from Elegoo whether they are planning to release a newer wash and cure station that could fit the Saturn 4 Ultra’s build plate entirely or perhaps a new feature like drying, since the last one was released 3 years ago.

I do see they are selling the XS cure and wash with it as a bundle but again all the reviews I seen show it not fitting so didn't see point in getting it.

Oh, sure: it could have been printed on resin as well, but the brass inserts cannot be pushed in by heat, as resin doesn’t melt.

Very nice. I have two questions 😊 You do not seems to be bothered by resin smell, what resin are you using ? Can you provide measurements of the printer with the lid raised, I would like to see does it fit my enclosure. Thank you

[@GeekDetour]

Sure! When the Lid is UP 90 degrees (it stays), you need 70cm of total height. You cannot safely operate it if you have less (the cover should at least rotate and become “horizontal”) it gets even taller if you continue pushing it more to the back. You need 43cm of depth with the lid opened. 33 is the depth of the printer with the lid closed.

[@GeekDetour]

You need at least 40cm wide to access the lateral and “turn” the printer on with your hand, as well as space for the Wifi antena. About Resin Smell: I don’t like it. I print much, muuuuch more with filament. I love the quality of the resin prints 😄 When I print resin, I set it and I go away… I finally have my Workshop separated from the house, so I “go back home”. To film the reviews, after a couple of hours I don’t feel the smell… but, yeah, I don’t know anyone who actually enjoy this aspect of the hobby 🤣

[@Zalzany]

I was always reluctent with resin I wanted one but got really chatty about my printers with professor second I mentioned resin she told me how a professor of hers she liked died from doing art in resin for years. She got a horrible dose of cancer from not taking it serriously and kept reminding me every time I mentioned resin about the VOC fumes, and other dangers. My biggest issue was the fumes, I saw the little filters but then read you replace them way too often, then saw the preorder for the 4 with the hose slot in back and bundle for their filtration system and yeah I finally put in an order for my first resin. I been printing and selling prints at art shows for last 2 years, even got p1p with ams in my collection but there was always some projects I wanted to do that FDM just couldn't handle so resn taunted me. And now with the flip so attaching a real filter system not the tiny ones you got swap out more often I feel more confident plus all other research like I got a couple spill trays already for when I almsot got the Mars 3 last year, But the saturn 4 ultra just seems to have all I want now. Plus after going from ender 3s to a p1p I can't do the "go cheap go better later" no more lol Like the auto calibrate alone feature on p1p makes it so my 2 other enders have not been used one time in over a year. I mean the p1p can print faster then the 2 enders, and again I don't have to spend an hour or more calibrating it if I let it sit for a long time to get good quality I just hit calibrate and come back later and its good to go. So yeah I like this has a real bed leveling an all those little features, I know I could "git gud" and not need them but at same time at the price why not just get a machine where maintenance is lower? Plus its more forgiving for some one new to resin. But yeah I can't wait for next month its gonna take more start up, but with the filtration and the printer I can always start with a container hand shaking and use the Arizona sun to cure. But eventually, I get cure and wash station I just hope some one comes out with a wash station that this can fit into. Hopefully, they start working on that soon at Elgoo But I am super excited for this I got ton of projects planed i couldn't do with my p1p, gonna miss AMS multicolor prints but not love no print lines I got sand off, and sacrificing fine detail for FDM

The handle on the lid is definitely needed. How Elegoo missed the need for that....beats me.

They missed that, right? Or did they? 🤔 Most of us agree a handle makes it far better - what we won’t agree is: how should this handle look like? Where should it be located? Last week someone commented here that, maybe by not including a handle, Elegoo is giving everybody a chance to make the perfect product for everybody. You will add your own handle, “exactly” how and where you thought best.

A couple of questions. Did they go back to a lead screw? Or is it a ballscrew? Looks like a leadscrew but I have a hard time believing that. How much resin do you think you can fit in the vat with the tilt function on? Hoping the absolute max is 1L or more.

[@GeekDetour]

Hi there! It is indeed a normal, trapezoidal, LeadScrew - not a ballscrew. And for sure it is less than a 1L

[@generationace]

@@GeekDetour Thanks so much for the quick response! That's so disappointing they went back to a lead screw! This blows my mind. I was going to refresh my farm with the ultra's and this may actually be a deal breaker for me. Ballscrews are so much more reliable and durable than lead screws in my experience. I wonder if there's a way to mod this unit to upgrade it to a ballscrew.

[@GeekDetour]

FauxHammer has a point in his review: on the Saturn 4 Ultra, the Build Plate travels much less, it actually just moves up when printing, not back and forth anymore. The repetitive motion is done by the tilt-release mechanism. So, the LeadScrew is probably good enough. The ballscrew could be completely overkill.

[@fearlessgamesofficial]

Quick Question, At around the 4:15 mark you put the print in a jar of I assume alcohol, and cure the print while sitting in the jar. Is there a particular reason why you are curing it in the solution instead of just having it sit in the cure station?

[@blastbuilder2430]

That hole is clearly air bubble and it seems the tilting mechanism might actually be able to eliminate that since the print no longer needs to be lifted out of the resin therefore is much less likely to form air bubble.

[@GeekDetour]

That’s what I think too - but it not always appears on the top of all flat models… But I always had them in the rooks, for example 🤔🤣

[@TheOctabreaker]

Ok, this is my first video I’ve seen of yours. Did you cure it IN water or ipa?! What’s the purpose of that? I’ve never seen that before.

Yeah! I will make a video about it. I cure in water. FormLabs has published a paper about it a long time ago.

I've been considering an upgrade from my Mars2 Pro to the Saturn 3 Ultra for the last 4-5 months, watching the prices fluctuate on Amazon, then this came out at a lower price so I ordered it the next day. Unfortunately they're not shipping until June/July 😞

Can this printer use elegoo rapid resin? I can’t find an answer anywhere.

[@GeekDetour]

Sure. It will print with any resin made for resin printers - specially Elegoo. You will probably use a shorter exposure time - you can run a calibration test to find the ideal time.

[@therealjonaswp602]

Is that IPA you are spraying with before removing the print from the print bed? :)

[@GeekDetour]

Yes, I washed the pieces and the build plate with IPA, spraying

[@therealjonaswp602]

@@GeekDetour thank you :) will be doing that as well - brilliant idea!

[@GeekDetour]

Yeah, when I print something small, I find it easier to just spray it a few times, let it drop, spray more… specially because my cleaning station in the end was quite dirty. I am changing the alcohol now

@@GeekDetour sounds like a good idea :) anything that helps getting those small pieces off the bed without damaging them. You are the first one I’ve seen who takes that approach with the spray. :)

[@GeekDetour]

Hi, thanks! Well, there is space for everything. I never print figures or cosplay - and there is a bunch of people who loves that.

[@GeorgMierau]

@@GeekDetour Nothing wrong with cosplay or figurines and busts, but after two years in printing with resin I feel like there are more entertainers than engineers (or comedians than scientists) on the "resin side" of KZbin compared to the "FDM side" and it’s somewhat sad in my opinion.

[@GeekDetour]

On this I totally agree with you: Resin is very artistic oriented - FDM gets way more technical information and knowledge on KZbin. I try to entertain as much as possible, but what really attracts me to 3D Printing is the possibilities, the challenges, fixing issues we face in the process. But I am not an engineer 🤣

[@fluxcapacitor]

6:14 _"[The camera] sees well in the dark"_ Uh? Other testers of the Saturn 4 Ultra out there have pointed out exactly the opposite: the camera is not IR, hence has no night mode ability, and indeed it cannot see in the dark at all. Someone even added an LED light strip inside the enclosure as a workaround!

[@GeekDetour]

I should have rephrased that, would be most accurate to say: “the Lid is super dark when you see from outside - even so, if there some light on the room, it’s enough for the camera to see well.” You are right: in complete darkness, there won’t be anything to see.

[@fluxcapacitor]

@@GeekDetour Ok. This makes me think: is it a good thing to light up the interior of the enclosure with white LEDs to record prints at night? I wonder if these LEDs, that emit in the visible spectrum, don't shine also some of their power in the UV spectrum - that would slowly cure the resin into the vat, if it's the case.

[@GeekDetour]

That’s an excellent point. Ideally, it should be an LED encapsulated in an UV blocking protection. I don’t know how much UV a white LED generates, if it is negligible or not. That’s for some research 🧐

[@Colorcrayons]

It doesn't matter if the handle looks terrible or not (it doesnt), what matters is that you fixed a silly and simple flaw that was overlooked by Elegoo. However, there is one big bonus to them not doing it for you, and that is you can now place one or more wherever you please that fits your needs. Because I can see just as many complaints about placement from consumers about where they put it. Now if they only could do the same thing with the switches/antenna/ports/power connection, etc.

[@GeekDetour]

Ha ha ha, yeah! Maybe that’s the point: when you make a product for makers, a controversial item such as a handle, it’s design and where should it be located… maybe the best thing for a manufacturer is to keep the product as a blank canvas 🤣 People will proudly make it “their own”.

[@mcrksman]

What does spraying the build plate help with? Does it make prints easier to remove? Or is it just to make it easier to wipe down for the next print?

[@GeekDetour]

It’s just cleaning with IPA. I find it easier to wash it together with the plate.

[@adriandolha9582]

Hy have ball screw ?

[@GeekDetour]

No. It has a normal trapezoidal LeadScrew with a brass nut. I don’t think that’s a big deal in this printer because the Build Plate doesn’t go Up and Down anymore. It just travels UP. The detaching movement is done by the VAT going down.

@@GeekDetour could go either way. The existing wash and cure are just fine, hopefully they just release a new bucket

[@dufric88]

​@@GeekDetour they actually do sell a bucket, at least on Amazon. Not sure about which regions. I was wondering if would be too much trouble to ask the measurement of the unit when front to back then the door is open?

[@JoeyBlogs007]

The handle is a good idea. Shame you can't use a resin printed handle.

[@GeekDetour]

Oh, I totally could! But the heat-set Brass inserts work amazingly well, melted on plastic. Resin just get destroyed… you can find a few videos… on resin, the best you can do is gluing the inserts, but the strength is far from being the same. I didn’t want to fight it this time - I just wanted a handle that I know works… and I have a BUNCH of printers to choose! 😂

[@twister3250]

@@GeekDetourhey, couldn’t you print the threads directly in the resin? coming from SLS and FDM and looking for adding this one

[@GeekDetour]

Here is the problem I had: the resin is quite more brittle and it tends to turn into powder at friction. I tested a couple of times and it holds well at first… but if you need to unscrew and screw again, it starts losing the thread. It was with ABS Like Resin. I would need to test again with more “serious” resins (that cost 3x more).

[@twister3250]

@@GeekDetour Yes I guessed that could be the problem, but since it is a one time mounting I guessed it could work but again I have very little experience with resin, for now

[@ajc4477]

Less height on Z, a lead screw instead of a ball screw. I would have run at this machine if it had the same build height as the 3 and a heated tank. I think they (mostly) missed the mark with this machine and I'm hoping the 5 will be better next year.

[@GeekDetour]

Oh, sure, the iPhone 16 will also be better than the current iPhone 15 (usually, hopefully). The Saturn 4 is an exciting machine because some changes are very welcomed (the lid, the latch-quick-release and printing without needing to adjust anything), all of that for a very accessible price. These are reasons enough for many people to get a newer printer. For people that are happy, lets say, with their Saturn 3, maybe it doesn't justify the upgrade.
