Elegoo Saturn 4 Ultra (HONEST review) 3D resin printer

[@Sharpevil]

I have to side with elegoo on separating out the heater. My printer sits in a fairly well-regulated room, temperature wise, and I've got nothing to gain from adding a heater to my printer. I'd imagine roughly half of resin printer users are in a similar boat, whether due to their setup or locale. It just makes sense to separate out that functionality, rather than incorporating the cost into every single printer sold. Elegoo's been the primary force driving down costs in hobbyist resin printing since the Mars 1, and I'd have to imagine a lot of careful cuts and consideration went into being able to put the 4 Ultra out at $400.

[@vogman]

That's a fair point... but I have a couple of Australia buddies who have no issues printing in the day, but find falling temperatures a night a big problem. However, I appreciate not everywhere is the same - and I'm a little biased on this particular subject 🤣😂🤣

[@TryptychUK]

I was getting failed prints for weeks inside my fairly warm house. Thanks to Vogman's heater project, I have rarely had a problem since. Temperature is more critical than a lot of people imagine.

[@jasoncombs3232]

My printer sits in the garage so a heater is desperately needed in the winter.

Great video.. minor note. The Camera is accessible by Chitu Free (the only chitubox I use), including the resin timelapses

Thanks for clearing that up buddy. I wasn't 100% sure. Now if only I could get it to work 😁😁😁

[@thedabblingwarlock]

The Prusa SL1 has been doing the tilt-release thing for years now. About time someone else did it.

[@photoboyjet]

The lack of a heater is no deal breaker for me. I do all my printing in an unheated garage, so I put my printers in insulated grow boxes with a ceramic heater inside. I was able to print all winter long with temperatures sometimes in the 20s F with no problems. A quick trip to the local hardware will take care of the lack of a handle on the flip lid. I plan on adding a Saturn 4 Ultra to my "factory".

[@vogman]

There's nothing wrong with fixes and workarounds - that's something I love doing. But my job here is to observe potential issues so folks know exactly what to expect when their purchase arrives 😁

[@davethepak]

That and the heater is $55 on their website - you can by one and still save hundreds from a GK two.

[@Vormulac1]

Weirdly the M5sPro is the same resolution (if you look at the pixel size) but has less Z height, so this is actually looking like a good proposition. I've long been a fan of the Anycubic RERF functionality, so to see something similar *finally* showing up on a Elegoo machine is glorious.

[@vogman]

The 12 and 14K issue is a weird one. The 14K improves resolution on the X, maintains it on the Y, I think. The difference on paper isn't worth worry about. However... look at the photos. I've done two 14K printers now. Compare the prints to the 12K's. Maybe it's me, but I swear the 14K's are smoother and just as detailed... the voxel lines are harder to see. That's why I take the photos, so folks can judge for themselves 😁😁😁 And the RERF thing... brilliant idea. Every printer should have one... that works 😁

[@Kerrathul]

It does seem to me that the tilt release is more about making the print less likely to fail due to sticking rather than it being all about speed. But Prusa's SL1S SPEED printer featured tilting and the marketing was HEAVILY about how much faster it was. I feel this is more of a marketing focusing on the wrong aspect rather than it being outright silly. I would love to see a comparison on if the tilting mechanism means I don't have to have as many supports on a floating model, because the forces exerted on the model are not as extreme. This would be huge.

[@LSCModels]

All power and USB accessories should be in the front. Why they place it on the sides or the back is beyond my thinking. People want easy access. Great review mate. All the best.

[@vogman]

Absolutely!

Elegoo had the usb ports and other accessories up front, but resin dripping and fep failure the ports were getting damaged. They moved them because they learned from people before. I have a mars pro and an og saturn and I see exactly why they did what they did.

[@vogman]

Yes, that tilt release is impressive.

[@DaggeeggaD]

Great review! What's the time required on your other machines for the Goblin head? As comparison between different printers I mean, that's more interesting than the specific mm/h calculation imo.

[@sjmaguirepdx]

For what it's worth - The drip tray is there to keep you from spilling resin down in to the gap required for the tilt mechanism to work... So not a waste of time or money compared to what would happen if resin spilled inside the machine. I agree it could be better made though I'm sure someone will create a model to be printed from more resilient materials.

[@vogman]

I get that, I really do. I kind of think of it as a safety net for Elegoo. As is, "There's a problem... what if the resin gets into the mechanism?" and the answer was, "Oh, just cover everything up with a cheap bit of plastic." That worries me. I think maybe a little more thought was necessary rather than relying on something that clearly won't last all that long. This is a wonderfully innovative design and I think it could be the start of something exciting. But for me it feels like they've designed a teleportation device and they're housing it under a bit of old tarp 😁

[@BoomerSG]

Nice review, I preordered one yesterday. Will be upgrading my halot lite.

[@vogman]

Hope you enjoy it! 😁

[@Katazo98]

Also I think it's interesting that once Elegoo announce the Machine was first going to be $399 Anycubic lower there M5s pro to $399 from $450 then Elegoo Raised the Price to $429.(actually US prices are still $399USD where as UK/JP are $429) so this machine is cheaper then their Saturn 3 Ultra in US which is kind of interesting.

[@vogman]

That's why I hate listing prices. They change daily. It's a very competitive market.

[@thesepets8498]

Elegoo Saturn 4 Ultra or anycubic M5S Pro ? the best ?

[@rolfvanderbijl]

A delightfully honest review as always. Looking into a new printer and your reviews are the first thing I look at. I agree with you on the incorporated heating but also get other comments about heating not being neccessary in any environment. But with me it is and in summer I might even need cooling. For now, I'm gonna keep an eye out of the progress of Elegoo because this printer another iteration further looks really promissing.

[@cenciende9401]

You're comparing FDM to resin, which do you need first as the higher priority is the question, the other comes later, because they are not comparable.

[@JustaGatherer]

@@cenciende9401 I am not comparing them, it’s simply a quandary of a decision. I’d honestly love to have a resin printer but with such a small room that I have to work with, the fumes are a big concern for me. It might be my deciding factor honestly. I’m strongly considering the p1p or s because I want to make pieces for cosplay and the bigger platform surely would help.

[@YourAverage_J0e]

Honestly this makes me really excited for the Saturn 5 Ultra

[@vogman]

That's next week 😉🤣😂🤣

[@jaym2381]

The missing heater is a major oversight. How much of the vat rim remains outside of the chassis when it tilts though? I would be inclined to use one of the belt style vat heating means, but am concerned the belt might interfere with the tilt.

[@mikejackson9585]

The speed issues are odd Vog. I find when I slice the exact same file on a modified Saturn profile and the Saturn 4 Ultra profile, it just about halves the time. And the makes since because the Ultra 4 completes a cycle in 5.5 seconds opposed to approximately 10 seconds on the original Saturn. To make 150mm/hour I'd have to use a massive layer height, but still the tilt is giving significant saving in time. Also saves me from tuning and cleaning the fails from tuning stuff like retraction speeds.

[@calrak]

The resin vat looks better than the one on the Saturn 3 Ultra - is the new resin vat for the Saturn 4 Ultra backward combatable?

[@francescorichichi7663]

I suggest you to verify the dimensional accuracy. The tilt mechanism should give much more precise dimensions without that stretch effect that all resin printers gives on z axis.

[@franky5angels77]

I'm so glad you didn't tell us all that it's the best low-cost mid-size resin printer by far. (I've just bought the M5S Pro) Although that tilt plate sounds like a great feature, I don't have buyer's remorse. Phew! 😊 Thanks for another balanced review. Cheers! ps. I added 1cm silicon feet into the foot contours on the M5S and it's far more stable and less noisy now.

[@lathelarson4009]

is there an easy way to lube those bearings for the tilt mechanism? seems like something that should be addressed.

[@vogman]

Not that I'm aware of.

[@Culky]

I happened to be looking for a reasonably priced resin printer when the Saturn 4 was launched so I more or less ordered one on a whim. It will replace my past-end-of-life Form 2, and it was funny to see Formlabs launch the Form 4 literally 2 days later, which is now an MSLA machine that still costs 10x as much. Anyway I will see how I go and whether I need a heater, but good to know the basic print quality should be pretty good, even if one of the first things you need to print is a handle to glue on the stupid hood.

[@Tuxon86]

Don't have a saturn 4, but with my 3 ultra, I got those high speed print when I used the included Voxeldance Tango slicer software. It has a builtin profile for it.

[@ianfong1000]

[@TheAndrian463]

Nice review again. My concern is that when there are more moving parts, the chance of a mechanical failure is more likely ... waiting to hear if any reports of the tilt mechanism failing after x number of hours, probably unlikely but who knows.

[@vogman]

Yes, many are saying the same. It's only after a few months of use that we'll find out for sure.

[@leonkernan]

I've preordered one to replace my old Saturn 1 (which is still going strong) The lack of a handle is a stupid thing though, that's going to be my first mod.

It's a silly oversite, but I've no doubt Thingiverse will soon be littered with suitable handles we can freely print 😁

[@MLaak86]

While I don’t intend to replace my Saturn 2 til it fails, in a way I don’t want to have to try to fix (I’m clumsy and a little worried about if I’d mess up wiring and such), definitely paying a lot of attention to printers coming out now since I suspect one of them will be the replacement I end up with (hopefully in over a year at least) and it’s good to see some sensible and quality of live improvements

I always encourage folks to keep what's working. Don't update unless you really need to or really want to.

[@forrestegan]

Some new features, some missing features…given a choice between the 3 Ultra and 4 Ultra, I would take the 3 Ultra. However, given the choice between the Saturn 3 Ultra and the Mars 4 Ultra, I went with the Mars for the square screen pixels (18x18 microns) over the rectangular (19x24 microns) of the Saturn. It’s been a little over 3 months and so far I’m very glad I did!!

[@vogman]

I love the Mars 4 Ultra... good choice 😁

[@sammkablaam]

I had a Formlabs Form 1+. It was similar in that it utilized a tilt feature on the resin tray to “peel” the print from the bedplate. Over time, I noticed the constant peel to one side would throw off the bedplate leveling. In addition, sometimes, the tilt wasn’t “deep” enough to execute the peel. Meaning, the bedplate would twist and deflect over the entire resin tray tilt cycle. It would never actually peel and release. This would always result in failed prints. Do you anticipate these issues with the Saturn 4 Ultra?

[@hellhole7422]

As you said, there doesn't seem to be much difference and there is actually a big difference in price. I'm still confused. I usually think about printing figures. I look at figures printed with Phrozen and people who work with figures. Their work is really nice. When I look at the works printed with other printers, I see that there is a difference in quality.

[@Fabrizio-xk1ly]

Good video But The maximum declared speed is always theoretical and for layers of a certain thickness. At best 0.10mm but some brands (including Elegoo) I assume imply 0.20/0.25mm layer to declare the maximum speed Only Anycubic explicitly declares the layer (which is 0.10mm) and says 10.5cm/hour (or 2.91s/layer with exposure 1.5-1.9 I suppose) for the M5s Pro and up to 17cm/hour (at 2.12s/layer with high-speed resin and with exposure unknown) for the M7 Pro I don't know if these speeds are truly achievable So you certainly can't use layer 0.05mm to measure the max printing speed in cm/hour In any case, I see that Lychee Slicer 6 for the Saturn 4 Ultra profile provides me with print estimates (I don't have the printer, I just did the simulations) of 9.03cm/hour using layers 0.1mm (at 3.99s/layer with exposure 2.0s) and 4.62cm /hour using 0.05mm (at 3.89s/layer with exposure 2.0s) Is this estimate too optimistic or will it be more or less correct?

Every printer on the market which has an in-built heater is also very expensive, though (and this one would have been too), and to me personally, it's not worth the money. You can get an app-controled thermostat plug and some kind of heating system (heater lamps, ceramic heater etc) for the same money, and you can set and monitor temps from the coach. Also, the vat tipping mechanism has some very solid fundamental principles behind it, so people will figure out to get the most out of it. I'm convinced it's going to be the most important speed innovation of this generation.

Love the info on this, ,makes me wish I waited.. BTW, I just wanted to tell you I gat a file you did (Thingaverse) for a little DnD cotage and printed it in PLA on my old Ender 3. I did 2 of them and they both turned out great. Keep up the great work!

[@vogman]

That's great to hear. Glad you enjoyed them 😁

[@Twigz11]

I'm torn between this and the DLP. Been wanting a resin printer for ages now. Phrozen is another option, choosing is overwhelming lol

[@vogman]

You've just got to decide what features you really need. Maybe this will help a little www.vegoilguy.co.uk/3d-resin-printing-which-printer.php

[@omi8567]

I wanna ask can this machine use phrozen castable resin ?

[@ilikenothingtoo]

5.5s a layer is faster than what I usually get out of my Saturn 3, which is 7.5s. So if the layer time is actually 5.5s that will save a bunch of time. Obviously not 150mm an hour though.

[@cenciende9401]

There's no reason it can't be 5.5s considering exposure is about 2. Should have shown the math in the review which makes 150mm/hr basically impossible unless doing .15 layer heights or something crazy at which point might as well use FDM, silly marketing

[@joaquinordoqui111]

Thanks for the brutally honest review 😂😂 i really enjoyed it 😁 Great content as always. Keep it up!!

[@Reborn_Fire]

Was looking forward to this review, thank you! I ordered myself one as I think it's a better fit than the GK2 for the price, since I'm also in California where a heater really isn't necessary for me. The rest of it seems so similar, I think I like the GK2s plate design more, but I want that tilting vat... And camera if it works lol. Edit: Is this noticeably faster than your gk2 or other 8-14k printers because of the tilt function?

[@vogman]

There's no doubt these companies copy each other, but if the end result is a better product for the consumer, and as long as no patents have been violated, then all's good I guess 😁

[@vladterra7353]

what is that resin you are using in this video?

[@lifeintheusa9612]

Saturn 4 Ultra, What type of screw do you use on the main plate movement feed? Ball bearing screw and nut or plastic slide nut and regular trapezoidal screw?

[@ericanderson4973]

I'm over here still rocking the 13 series 1 Saturns. lol

[@vogman]

If it's working for you, that's all that matters 😁

[@makers_lab]

Is the vat actually innovative, given that the Form 1 and 1+ had a tilting vat years ago, as did the Prusa SL1 and Prusa SL1S. Now maybe Elegoo have done a better job than Formlabs, who I believe didn't have a tilting vat in their subsequent models, but I think we need to see how it pans out with this model. I honestly struggle to see where there's any innovation with this model personally. Like many of us, I'd like a heated vat so we don't need to use brew belts, automatic filling, level sensor, vat temperature monitoring with a contactless low res thermal camera or other sensors, replacing the -shitu- chitu firmware for something decent and thus a better print experience (Bambu show how much better it can be having custom firmware over what others are doing), and a slicer that can leverage said better firmware. Providing something like Fujifilm Prescale might be useful too for validating actual bed levelling (as opposed to Z height), but Prescale is super expensive. Heygears seems sort of like the Bambu of SLA, with a somewhat integrated system that's an improvement in the experience, but I don't think we're seeing anything particularly exciting anywhere. Wondering if Bambu are looking to take a lead in this space too; certainly hope so!

[@awildtomappeared5925]

Vog man, there is a chance you expirience with the 4 cones being off might not be the printer... The cones v1 is only supposed to be used in the middle of the fep, and printed alone, as printing elsewhere can affect how the cones behave due to uneven fep pull forces. The cones V2 and now V3 avaliable on the table flip foundry discord have walls around the cones so this shouldn't be an issue. The cones v3 also has a dimensional accuracy test which I worked on, it's in beta on the discord server as that is being refined.

[@vogman]

In fairness I did other tests than the cones... I just thought the cones were easier to demonstrate 😁

[@shardperson3777]

The tilt release is the most exciting thing ever for me as a Dice Maker because the huge pull forces make the dice elongate in this kinda non-linear way where the closer to the build plate you get, the more elongated it is along the Z axis (so you can't just squish it in the slicer to compensate), this elongation then has to be corrected by sanding the dice while applying force at an angle, very carefully, and even with hundreds of dice made, it's still hard and I can't get them perfect, only prints with a Form 3 come out without this warping, thanks to the tilt release. But seeing the mechanism Elegoo is using, it worries me that the pushing up against the print before pulling down might actually make it worse in a different way. It also worries me that the Tilt Release is marketed exclusively as a fast printing thing, it might just really not help with dimensional accuracy at all. Also It makes me worry that the whole mechanism might wear out and develop some wiggle room, bringing the alignment of the screen with the collimating lenses into play, and causing a loss of detail. This wasn't a worry in the Form printers because of the lack of a screen, obviously.

[@vogman]

I have the same concerns about the tilt mechanism. Usually anything that moves a lots, wears a lot. But it's way too early to say anything about this yet. It's a great feature and I applaud Elegoo for it 😁

[@Kovand97]

The tilt release is a wonderful thing if done correctly, like in the Prusa SL1S SPEED 3D printer, which is open source for years. I tink Elegoo might just found it finally :D

[@MattJonesYT]

Maybe the STL can be scaled nonlinearly by hand in blender on the Z axis to account for the elongation?

[@joeargyle]

I've owned machines with similar mechanisms. They're fine when they work but moving parts introduce another possible point of failure. The machines I have eventually had issues returning the platform back to zero/home consistently. In both cases this mechanism was the first thing to fail. Personally I'm not a fan, but maybe elegoo has a more reliable solution.

[@patprop74]

Only 10 years behind everyone else huh, I built in that feature on first home made DLP printer 12 years ago! the first Formlabs form1, which i still own, had it, and again, that was also a standard affair a decade ago.

[@3lcost3]

Any word on the ACF release on this one? I was watching some old videos from Fauxhammer where he complained about the ACF smoothing details but then it wasn't the case on the Saturn 3 ultra

[@vogman]

Well from my observations ACF liners were producing vertical lines on prints, and I've noticed that manufacturers have stopped fitting them, so I'm not sure.

[@felixxcatus]

for my purpose and situation, the tilting tray really has to make a difference, otherwise the regular Saturn 3 is better (for me)

[@richvip93]

Thanks for your videos! They are very fun and informative! I'm thinking about changing printer (I have an anycubic photon SQ), anything will improve what I have xD and I'm thinking if the saturn 4 ultra or the anycubic m5s pro, both seem good options but the elegoo seems better for the new features it has(I think)... Thanks a lot VogMan!

[@rmfberry261]

i recently got he saturn 3 utlta and was supper bummed I didnt expect a new version a month and a half later. honestly even though it has some really nice quality of life improvements like the newer hopefully better poor spouts and flip up lid I am happy with the 3 ultra now. i feelthey missed the mark not having any sort of heater weather It was chamber or vat and I didnt see a spot to run a power cable to have a addon heater. I'm sad to see they didnt go a deeper vat and a skirt for build plate like the gk two that way you dont get resin ontop of he build plate. im curious about the tilt to release if it will distort the print making ti tsightly taller up front vs back. im sure it will help reduce the suction forces though

[@vogman]

Never worry about missing an new version. There'll be another one out very soon, that's just the way these companies go. Enjoy what you have. I made some fabulous prints on the S3's.

[@racingdad8342]

Hi Vogman just want to ask of you have vibration/weird sound issue when printing on a high speed print mode on s4u?

[@vogman]

No, I can't say I experienced anything like that...

[@RustedOatmeal]

Just ordered!

[@mylifeisajoke1]

Is there a way to print without the tilting? I'm interested in all the features *except* for the tilt release.

[@dan3dprint183]

Buy the Saturn 4 all the futures without the tilt release and cheaper.

[@Twigz11]

You should take a look at the non ultra Saturn 4

[@vogman]

Not that I've seen, though I agree that would be a useful feature to add - just in case.

[@samhughes1747]

I'm like, wow, this is basically a Creality product, with how many things fall in the "oh, I'll need to make one of those for that" category.

[@dbretton]

Outside of a handle, what other things would you need to make?

[@danielsamsami5340]

What do you have to offer to buy in the range below 450 dollars?

[@vogman]

This Saturn 4 Ultra should be in that price range and is an excellent printer.
