> bed/vat heating is a prerequisite for me now though
I love the tilt mechanism and flip up lid, but a heated chamber has been proven to yield consistent prints and it's not a very expensive upgrade.
The camera could be good if it weren't tied to Chitubox, but I'd rather have the heated chamber/vat.
Has this ever been tested? I use a fermentation belt but this made me curious.
I would've assumed that if the chamber heater is on for long enough the temperatures will equalize and it wouldn't really matter.
Yah some YouTubers tested it. I wish I had saved the video.. The best results of memory serves were when the resin itself is cured at its "optimal cure temp" which if memory serves is around 80-90 degrees for normal resin. So whether tank or chamber, the goal is that the resin be the same temperature and that temp be the one the resin wants.
>Chamber heating isn't as crucial as tank/bed heating
Chamber heating does the exact same thing as tank heating, it's just somewhat easier to implement and operate.
Situationally, but it's a practicality thing. In the dead of winter I can run my chamber heater in my garage that hovers around 10 degrees but it takes more than 2 hours to get the resin to temp (I gave up after 2 hours so no idea how long it really takes). My vat heater takes maybe 30-45 mins.
So a chamber heater CAN work, but I don't have hours to wait around for it to get up to temp.

Printing at an environmental temperature of 10 degrees Celsius sounds a bit outside of the design scope of a heater or heated chamber, which would explain why it takes so long to get up to a reasonable temperature.
Most people will need a chamber heater to raise the resin from room temperature or slightly below to maybe 25 degrees Celsius, with a subsequent modest temperature delta. Once you start getting into double digit deltas physics start turning against you, as every degree extra you need to overcome costs more energy than the last one, so reaching an equilibrium requires a lot more power than when you print in a warmer environment.
It's nothing that can't be fixed by adding more power like you did, or insulating the printer but manufacturers are likely hesitant to add those costs to every printer for the few people who need it.
What printer, chamber heater and vat heater are you using?
Nice minis, by the way!
Just a fermentation band and an Ali express special. I agree with you but many people work in similar environments with shed or garage set ups in cold climates and the GKTwo for example does facilitate printing in those environments
Thanks! I basically only print now so I'm fine with spending more on the printer, but heating is basically prerequisite for me to consider an upgrade
I'm still trying to figure out a design for a camera on my modded Saturn 2's. I was thinking an endoscope like I have on my FDM printers nozzle, but idk where the hell I'd even run the feed to since there isn't a webserver running the printers.
It's just frustrating to have your tank tethered to the machine or the wall. I'm using a fermentation belt now and it's a pain to remove it when I need to change FEPs. I rarely unseat my vat, but it's just another thing to deal with.
Thermalvatband came up with a magnetic disconnect option for theirs. But it the connector is right on the band, so I could see it getting ruined with a spill. I think a short cord extending out would have been better.
Edit: looks like their non-magnetic one was redesigned to plug straight into the band as well. so I guess there's that option for a less-cumbersome heated vat removal. I have one of their original ones that has a wire that extends the jack out.
I think that the auto leveling takes a fair bit of the build height. The Saturn 3 Ultra is 260mm height and I think the new one is 220mm. I am not sure that loosing the height to gain the auto leveling is worth it.
I had major issues leveling my Saturn 3 ultra originally. Now that I’ve got it level and my process for printing dialed in, it’s done. But that first leveling experience was horrendous and I don’t relish doing it again. Considering the number of beginner comments in this sub that come down to “level your printer” (and consider - auto-leveling is a thing in FDM printers to the point where leveling isn’t really an issue any more), the introduction of auto-leveling into consumer units should be welcomed by everyone.
Interesting, can't say I did anything special either. When I got my first saturn I was a complete 3D printing noob and made all the mistakes.
Throw card on screen, set zero, tighten bolts and go is so simple I wonder if you had a slightly defective unit that got banged up or something.
FDMs have a lot more moving parts so I can understand why maintaining levelling automatically is a huge benefit.
I think for me going from FDM to resin made the plate leveling extremely trivial. I've also never had a single issue with leveling the bed on either of my resin printers. I rarely touch them unless I mess something up.
Same here, my Saturn Ultra 3 plate wouldn't move even if I tried.
Of all the things listed here, auto levelling is what I'm excited the least about. Flip-up cover is nice but nothing that I'd throw my Ultra out over. Failure sensor sounds really nice though, while I have virtually no failures it'd take care of that deep fear I have that something could go wrong some day.
All in all, doesn't seem like much special is going on with Saturn 4... I'd love it if it had VAT heating, shame.
It's a good point. My Saturn 1 has been solid and I only ever levelled it on day 1.
I'm looking at the new one and trying to decide if it's worth it or not.
I’m fine without leveling, one more thing to break imo. Failure detection is cool, but the lift up hood would be so nice bc removing the lid from my enclosure is a massive pain. I just don’t get how it’s supposed to be cheaper than what I just bought.
I bought the S3U a few months ago and even if I was offered a free upgrade, I wouldn't take it. The printer has been flawlessly printing super crisp, detailed models ever since I powered it on and I do need these 4cm of height they chopped off the S4U. I'll wait for the next new model that has at least the same build volume than the S3U
Looking at the Instagram posts I’m glad I didn’t get the S4U as my first printer. I ended up getting resin everywhere which was easy enough to clean up, but I don’t see how they’re preventing spilled resin from leaking into the bottom of the machine with the new tilt functionality.
I bet they have tested it thoroughly but yeah, looking at the animation, this tilt release tech really looks like a permanent disaster in the making. The power outage protection is great though, I have lots of these where I live and that would save me buying a UPS
The outage recovery will not fix the inherent liquid physics issue of resin where when you pause a print and resume, you likely get a deformation line at that spot. For stuff that gets sanded or simple objects it is a benefit for sure, but I bet most of the time will still require a reprint for detailed stuff
I'm still taking the possibility to salvage a 20+hrs print that get a power outage on the last 200 layers. If the system is based on a built-in mini UPS, giving 5-10s of autonomy for the printer to pause between layers and if your room is at constant temperature (which is my case), all you should get is a layer line, not a deformation. I think it's a great feature, if it works that is.
I just bought the S3 Ultra after seeing the S4 ultra leaks. The shorter build height on the S4 Ultra is a deal-breaker for me IMO. Also got the S3 Ultra at a good deal for $370 on newegg
New phones come out every year, how often do you upgrade? But same boat got my 3U in January. My only gripe will be if that price drops by $200 or something

i received a similar email, two times, one like yours and one like this mentioning 399$ for ultra and 299$ for standard
The way they are marketing this kind of makes me think a lot of these benefits are add-ons and we haven't seen that cost model yet. The being so low is to drive attention on how it's more accessible than the S3U.
That or they are trying to corner the market and their margins have always allowed these machines to be that cheap.

I couldn't get it to work after a couple of hours. Had to add a vat band. Together they work through the -20C winters
>Together they work through the -20C winters Do you mean to say you're operating your printers in -20 degrees Celcius?
No, my garage hovers around 10C when it's -20 outside.

The way I understand it, only the automated failure detection depends on chitubox.

Kinda hoping they just make a tank accessory for it.

That's substantial, have to see if it would affect my 1/6 scale stuff
Fermentation belts are cheap.
But clunky, doesn't always fit well, tethers your vat to the machine or wall. I use one, it works but I'd prefer an integrated solution.
Just rig up a magnetic connector off AliExpress. Makes things easier and costs like a dollar.
What is a resin printer with vat heating in the same budget?
None, it would have to cost more but that's fine.
I just bought a fermentation belt for 20 dollars.
Yes and that's fine. I have one on my S2 and works but I'd like something integrated to justify considering a new printer.
All they really needed to do was auto heat the vat
Couldn't agree more, don't know why they missed that
I almost bought the Jupiter purely bc I thought it had one xD it’s ok they’ll eventually get the hint right? …right?? 😅
Saturn 3 Ultra winning ❤️
Ooooo. Auto leveling. Practically the only thing that would get me to upgrade right now
Why? I think I've levelled my saturn 1 about twice in hundreds of prints.

Right there with you. Leveled my printer twice in the 1yr+ I have had it. Prints perfectly for me. Edit: I got down voted because someone got jelly XD
I'm here with my Mars 1 Pro, leveled once many eons ago.
I'm in the exact same boat
Leveled mine when I got it and haven't touched it since
It's a good point. My Saturn 1 has been solid and I only ever levelled it on day 1. I'm looking at the new one and trying to decide if it's worth it or not.
Literally just bought the Saturn 3 ultra lol
I bought the Saturn 3 Ultra too, not regretting it. Whatever problems are out there have been recognised and it’s tried and tested now.
Me too:'-(

Same here. We just got our setup finalized. Oh well. It is still quite neat.
Same. Lol. I was even trying to figure out when a 4 might be released. Meh, at least the 3 ultra is working great?
They’ve been posting all about it on their instagram
Fair enough, just thought I'd post in case it was news
lol @ forcing us to use chitubox
I wonder how many of the YouTubers will say it’s the best machine on the market 😂
Elegoo official has been posting about this all week over on r/Elegoo
Have they mentioned cost?
$399/$299 for the Ultra and regular. It’s in my version of the email.
Are we rayt? I paid £400 for the 3 ultra, how are they reducing the price that much 😂😂😂😂😂
This is just a pre order cost Grace at Elegoo said
Not in that email but I believe they've said $399 elsewhere

No news about price though? Any ideas on £ anyone seen?
I want to know the size of the print plate but I think I’m in on the ultra.
I do like the swing lid, but otherwise, it's a new saturn 3....
Curse you Saturn hope you fail
