Out of all the 3d printer reviewers, your videos are most heartwarming and inspiring :)

[@GeekDetour]

Oh, thank you! You have no idea how much your words meant to me. I am very emotional - which sometimes makes the task of producing a video very hard if I don’t have a strong connection with it. A special curiosity, something I want to change or test… That’s why I never accept to review plain clones - because usually you can only say: “yeah, it’s cheaper”. Soul killing 🤣

Nice use of the bib! I really enjoyed this review

[@GeekDetour]

Hi Ross! How are you doing man?! I am anxious to know your take on the Saturn 4 Ultra - I’ll check now if you finally published it. I am excited about this one because I think it made Resin 3D printing quite easier than before. I never liked the bed leveling with the ball head. And the price is superb. Now I’ll watch yours.

[@GeekDetour]

Oh, @FauxHammer, did you ever get the bubbles in your Rooks or other models, on the top layer? On other resin printers?

[@FauxHammer]

@@GeekDetour I had no bubbles in any of my prints. I just looked now and I have 16 models sat next to me all sans bubble!

@@GeekDetour I just need to finish making my resin room before i start again and get this printer. I was dumb and printed in my bedroom for a year but recently moved it all out and moved my FDM printers to my room an my resin to a room I will ventilate.

That’s a good move. Now I have a dedicated workshop that is not part of the house - it is SO different than having everything with me in our sleeping room 🤣

[@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

I have the saturn 3 ultra and my rook doesn't have those holes. Seems like a great printer but it did need a handle. I only wish the power and USB were on the front with the power plug and WIFI antenna on the back of the unit.

This machine is looking seriously impressive for the price... If it really fixes the "Hole" problem I am sold!

[@dailyprofitcenter]

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

[@GeekDetour]

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.

Ps: I don’t like Julien Mairy’s handle… 🤣 He probably doesn’t like mine - our handles are being downloaded by different groups of people.

Great video as usual. Very funny and informative.

Glad you enjoyed it ❤️

[@aaronb1138]

The bed re-leveling definitely needs more research. I've adjusted mine the same way, and it needed loosening on the left (left from looking at the machine, platform right?) as well. The issue is this changes the spring pre-load and whether or not this correctly maintains parallelism on subsequent layers as well as the behavior of the force sensor needs investigating. I'd spend good money on a 1st or 3rd party bed upgrade which integrated "perfect" one time (multiple geometry locks) leveling (jack screws per corner?) while still leveraging a spring-loaded system or not. The spring-loaded bed and tilt release substantially change base and transition layer geometry and pressure. The result is inconsistent elephant foot across prints with the same settings and resin. No single solution results in a clear, consistent dimensioning of the first layers and I find dimensioning flaws as high up as the first 5-8mm of print depending on how much bed is used and the parts being printed. Large base layers need an option to step the tilt mechanism itself much slower instead of having to practically fry the base layer to the bed to safely adhere larger prints and warping / partial fails is still an issue with some resins.

[@GeekDetour]

Hi there! Please, watch my video on the Mars 5 Ultra - I present a solution for what you just described: kzbin.info/www/bejne/oYvapomAZ6eIosk

[@aaronb1138]

@@GeekDetour I was referring to using your method with thread locker from the Mars 5 Ultra video. I used this method on my S4U, so I put my comment here not thinking about being clear about that context as I was bouncing between tabs. My concern is leveling the bed by loosening the screws to get even pressure at "Z=0" against the screen also changes the spring pre-load. While I think the adjustment is better than not as I did have some left to right adhesion and base layer thickness / elephant foot variations, the changed spring pre-load affects the spring compression between the upper base plate and build plate during all travel moves including the "compression" stroke the S4U / M5U have during the screen / tank rising back up from release. With the camera, you can see distinct flex of both the upper base, build plate, and arm during each part of the release and reset to "top dead center" stroke. It's especially pronounced during base / transition layers and the first couple dozen after. By the way, on the resin pooling at the built plate edges, yeah definitely getting my money's worth out of a silicone spatula I keep next to the printer there. That said, most of the resins have pretty strong surface tension, so any kind light contact I make with the tank sides pulls resin off quicker. With that in mind, I might test notching my build plate edge / corner or adding a short thin wire barely sticking off the corner to act as a wick. Sanding to a steeper edge is logical, but the bare metal (vs paint) and sanding grooves will also increase the energy available to keep the surface tension holding the resin in place.

[@sirfrancisarthur]

Try not to shake the bottle like that but up and down and upside down ;) it will mix much better

[@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).

What do you spray it with to dismantle figures from plate? (Great review, now I want one!)

[@GeekDetour]

[@shinchin384]

Just waiting for the 16k saturn.

[@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.

[@xeraoh]

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. 👍

[@abstractoid]

​@@GeekDetour I heard this before and thought only good done for water-washable ones. I'll give it a try tomorrow because I also have tacky prints and couldn't figure out a better way yet. This might be it, ty for the tip!

@@abstractoidoh, but before I put it into water to cure, the part was already super clean with alcohol.

[@carbonguy]

This is a great video! Would it be possible for you to print something fairly tall and solid using clear resin, any resin? I would like to see if the tilt eliminates the bubbles inside the prints and with the clear resin it will be easy to see if they are still present.

[@GeekDetour]

Now thinking of it, I think I never printed with clear resin 🤔🤣🤯

[@photoboyjet]

I started resin printing with the original Saturn. I now have two Saturn 2 printers in my garage "factory". I passed on the Saturn 3, but I'm stoked for the Saturn 4. As soon as my tax refund comes in, I'm buying one!

[@GameUpOG]

What was the stay. I've never seen someone use it. Just water or some IPA to help it get off the plate?

[@GeekDetour]

Actually, I didn’t spray on the plate to help taking them off. I just like to clean everything together. Since the build plate didn’t fit the washing station, I ended up cleaning just by spraying.

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

Your question is super valid - I will write to Elegoo tomorrow asking about their current Washing Stations because mine was their first one - they could have reshaped the opening of the container, keeping the rest of the unit. 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.

[@roosma82]

Nice video, thanks! Really is easy fixing the handle problem as you showed, think I would go for some kind of suction cup handle maybe

[@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.

A good review and nice solution to the handle-lacking case, but what is the reason for using a liquid while curing your print and what is this liquid?

[@GeekDetour]

Thanks! Oh, the handle is on Printables! I made an adhesive version too. And the liquid is a mixture of 2 parts hydrogen, 1 oxygen 🤣

[@GeekDetour]

[@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 🧐

[@Dandolos98]

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 🤔🤣

I think Elegoo had a different vision in mind: on their promotional video they put the fingers in the space between the upper part and the part that goes in the resin - which would be safer… but I never do it myself… I talked to them about it.

[@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.

[@RossMorton]

the only way i've found to alleviate the bubble issue is to increase rest time before print

It is so funny: people that swear they never had the bubbles, and people that fought them a lot 😂 I’ll make another video about this thing, but I am glad to see I was not alone!

What was the leveling plate you used around @4:05 that was too small for the print? I'm looking into getting the Saturn 4 Ultra with the Mercury XS, but I'm not sure if it'll be too small in some cases or not.

[@GeekDetour]

The plate is the one that came with the Saturn 4 Ultra, it almost fit my washing station (which was the first combo). I need to ask Elegoo if their newer washing stations have a wider opening.

When we push the top part of the lid, it actually lifts the front of the printer 😆

[@vedranabdihodzic1650]

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 🤣

@@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.

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 🤣

[@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.

[@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.

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.

[@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”.
