Like it's been said, I think we have reached the limit on human perception, being able to tell the difference between 18 and 20 micron screens just isn't doing it. I think companies are having a real hard time innovating beyond "new fancy screen". The next jump will hopefully be in ease of use and convenience. The features like auto-leveling, fail detection, bed heating, are all going to help people get into the hobby while also being a more convenient experience for veteran printers.

I've got a Mars 3 and just got a Saturn 2 and I'm using the standard Elegoo Gray. The mars on .035 (figures) and .05 (bases/terrain) works perfectly and gives me more detail than I can paint and see from a foot away. The Saturn 2 - well got it dialed in (I'm pretty sure I did) and got it running with the first batch - 4 mounted barbarians. Seems to be working fine and I'm doing .03 for the layers.

I agree on a bigger build plate - I've printed some dragons on the Mars they're in pieces. On the Saturn - they should fit all at once and some 2 at once.

For those worried about the screen protector on the 4 ultra - it is there, its under the tape and takes about 10minutes to replace. I just did it. Elegoo sent me a replacement FOC which took a few weeks over xmas. I'm not sure why they aren't for sale on their website

I was considering Saturn 3 Ultra but went with 2x Mars 4 Ultra. One for flexible parts, the other for hard parts. I only use 2 resins, Clear Impact and Elastomer-X from Liqcreate.

you are so correct on just about everything. Especially the VOC thing. Tiny charcoal filters will never help VOC - you need massive volumes of airflow into massive filtration systems (comparitively speaking to the printer size) to actually do anything about the VOCs. It is far easier, and cheaper, to just vent them outside. A flexiduct and a large, high pressure fan will do the trick.

I actually sat down and looked at each point, and imagined if i would use them 'every print' - 'every other print' or 'rarely on a print' - and ... honestly the Ultra to me is the way to go. I am still holding out on my first resin as I don't have the real ability to yet (fumes need taken care of, low ventilation area and VOC don't mix well) so maybe a slightly better unit will arrive before I actually buy - but it seems to be the one I aim for, and to be honest there's so little for me to actually expect better - it comes down to 'nice to haves'.

Things like - a resin auto-dispenser system where the bottle is upside down and gently flows resin in to keep it topped off. (seen on other systems) - or a vat warmer, to heat up the resin to it's best curing temperatures. (this may or may not be achieved by turning the vat into a heat sink for the other parts as well, possibly eliminating the need for a fan) or slightly larger build volumes, while retaining the roughly 25 micron excellent print detail. (+/- a few microns, doesn't really matter to me) and of course a vat with a tapered edge to make pouring excess out easier, and more controlled, for when it's time to change colors or types.

But these are all literally just 'nice to haves" and not "musts" - the Ultra... seems to be by far the best resin printer out right now, at it's price point. +/- $100 USD.

I upgraded from my mini8k to the mars4 ultra. I can noticeable see a big difference in print quality. I did change the screen to nfep. I really didn't have a problem with the texture the other screen was producing. Will probably switch back to see if i still feel that way. It so much faster to print as well. The absolute thing that I feel in love with was the wireless transfer.. i will never go back..its the shizzz. All priters should include this feature.

Great review as always!

Definitely shows the difference between the Saturn and Mars. Both in specs, performance and quality!

07:16 I have a Mars 3 Ultra. By the time I purchased it, it was also marketed as having a tempered glass protector for the mono LCD. But only when I had a failed print and a small bit of support fall and lay underneath the resin vat. When the build plate shattered the LCD, and then I realized the protector was actually underneath the LCD. Like at the bottom, between the UV light unit and the LCD itself. I knew this when I ordered a replacement LCD and figured it out. Wondered why the hell a protector glass was underneath, where zero chance it could get damaged or prevent the LCD screen from being shattered by any small hidden cured resin bit.

Thanks for the fantastic reviews, coming from a super newbie it really helps!

[ZeNex]

So happy to get 4 ultra.. then realised I need a whole spare room for ventilation, mask and curing station... damn

[jaakkosippola]

Your resin might be better but it is not wildly available. I am still waiting for it to be released in other EU countries.

[Lurker]

Just want to give an update. Its Nov 22 and Elegoo have still not released a FW update for the Mars 4 and Ultra and the AA issues still persist with the .goo format. I sent a support message through elegoos site and the response was that they didn't know what I meant by an AA issue.... Soooo yeah thats where we're And the wireless update function is still not supported. Essentially the printers have had no improvements since launch.

[S.A.S.H.]

I got the vat and clear film for my Ultra. Along with clear replacements for the vat that came with it. So now two vats both with clear film.

[danyo]

Thank you again for this review! This told me exactly what I needed to know. Looking for a PFA vat now for my Ultra. However, I'm seeing FEP options, not PFA.

[jorgeviveros]

Amazing video!
it would be cool to compare these to the Sonic Mighty upgrade, :D I read it is 19 micron and haven't seen many people covered the upgrade!

[andraslibal]

Thanks for the video, this is useful to me I had an Elegoo Mars 2 up until now but IO scratched the LCD and looking at the replacement cost ... I realized it could be a time for an upgrade.
Please do look up how to properly pronounce Fresnel you seem like a highly intelligent individual who should pronounce that correctly.

I have the 4 ultra, TBH the fep thing is totally irrelevant, it's going to be replaced at some time, so I have no idea why it's even a second thought, never mind the big issue you appear to have with it.

The fep is a consumable just like the resin and IPA, you choose what resin and fep to use in order to suit your own needs - irrespective of that which came with the printer.


The only issue I have had is with the WiFi, and I think that is more to do with Tango!

Every so often, Tango can't find the printer, checking the network and attached devices, and the mars 4 ultra (with a fixed ip address) is always there with 192.x.x.24 in my case.

Removing and reinstalling Tango, and magically it reappears!

And yes, the move/rotate within Tango is too clunky, but overall, it does supports and so many other things better than cbox or lychee out of the box - let's face it, there isn't perfect software out there.

Great

(Felt I need to add the great, as if it's obligatory)

Hi ross! I just discover your channel and your videos are beeing so much helpful. I'm planning on buy my very first printer. Although you say you prefer the model saturn 3, the most I can afford would be the saturn 2 8k. Which one would you recommend, ars 4 ultra or saturn 2 8k?
After watching many of your videos these would be my two options.

Thanks a lot!

[JoeyBlogs]

I guess their version of the screen protector is the plastic which it said to remove. Maybe they meet screen protector for when transporting the printer.

[nfinnnn]

Hi Ross! This was a really helpful video as always! In 12:10, I would say the regular Mars 4 has slightly better print quality both with pfa and acf, right? The thinner lines in the bottom left corner of the calibration plate seem to fail with the Mars 4 Ultra. Any thoughts on this??
Thanks a lot!
