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

During the whole video I was thinking "oh great another cool printer I want, but cannot afford" (I thought it would cost $1K+) but seeing it is only $400 this will definitely be my next resin printer to go with my Jupiter.

HANDLE - Get the STL files for my MOD: www.printables.com/model/870460-handle-for-the-elegoo-saturn-4 2 versions: with Screws (needs drilling) or Adhesive (Double-Sided Tape)

This machine is looking seriously impressive for the price... If it really fixes the "Hole" problem I am sold! No matter the printer I use I always have to sand down the hole on top of the heads of models. The timelapse on the camera also looks great for the price. Awesome video, glad to see you back!

Son, congratulations! Needless to say I’m your fan number one. ❤. Excellent to see another resin video! 👏🏻👏🏻

Beautiful video. Excellent work, as always! Congratulations, friend!!!

I have an original pre-order saturn and have loved it.... This is the first one I have seen that has made me feel like an upgrade would be worth it. Ive never seen those holes on the top layer.... Never heard of that before.

I love the handle!!!

Awesome! The legend is back!

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

You really explained alot of the features that come with the S4U. I love it. Wish i had one but right now i dont have the money, hopefully i can get one in the future

It's a good day when Geek Detour posts a new video :D

I like the handle you added. On my Saturn and Saturn S"s I added a knob on the top of the covers. Easy on and easy off now :)

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

Great video as usual. Very funny and informative.

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.

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?

OMG! You can actually print 8 Resin Calibration Tests at once, not just 4: ru-vid.com1YDN2oVcC8I?si=8hFlgcacP7vwiY28

Yeah wish I saw this before I preordered this morning then found this when trying to share videos of why I was so excited for my toy coming next month

Nice use of the bib! I really enjoyed this review

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.

Is that washing station the mercury xs? They sell it as a bundle with the ultra 4 and Wondered if that would be an issue. Should i look at a different washing station?

Do you have to take the machine half way apart to replace the screen or is it easy like most new machines. Screws and comes out from top?

Great video loved the handle

thanks you for explaining the different between the ultra and Saturn 4.

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!

Fala Everson, que video maneiro!! I am subscribed!! Duas perguntinhas: Sera que tem lugar dentro da impressora pra colocar um aquecedor de ar, desses pra impressora 3d? talvez acoplado aa tampa da impressora? Outra coisa, eu moro na alemanha e estou tendo dificuldade em imprimir resina transparente pra placa de mordida odontologica, eh uma resina viscosa. Voce ja teve problemas desse tipo no inverno no Brasil? o Modelo sai distorcido com um efeito tipo "GHOSTING". Mesmo aquecendo a resina continuo tendo esse tipo de problema. Me da uma luz!!! (voce prefere que eu escreva em ingles?)

The handle for the lid is a great idea.

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.

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

Looks interesting, does it need a special type of resin ? (the "V2.0" resin they list as add-on)

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?

Is that the Elegoo washing station? Im thinking of getting it with the Saturn but if it doesn't fit the build plate, I might just skip it.

Came here for the resin calibration directions! Thanks! The handle is a great idea! (Edit) Subscribed.

Thank you for your Video , As a beginner its censusing which one is better printer , can you plz tel me Saturn 4 Ultra or Anycubic photon M5S Pro . which one to buy

mmmm i want. does the wifi work remotely or do you have to be connected to the same wifi? i travel a lot for work and i was thinking it would be a nice thing to come home to a finished model waiting to be washed and painted.

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?

hi, for the vent opening you can use a steal plate and on the vent hose attached a magnet with a plate for quick disconnect

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?

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

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.

Curious if the Saturn 4 green lid will work on the 4 ultra?

great video!

What resin did you use here was it the 8k quality or the v2? I assume the 8k would be the best to use on these newer machines? Anyone have any useful input?

Thank you for the video ! Nice presentation and job ! .. so about the accessories I will not going to drill the lid but use a sticker 😅😅 also good idea ! Thank you again

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

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

Do you use water or IPA in the glass inside the cure station and why?

4:14 is he curing the resin in IPA ? I've never done it before that way. Is it smoother or why should i do it this way? :D

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?

thanks for the video

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.

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

Looking great, why didn't you use the same printer to make the handles? Wouldn't they have a nicer finish than the FDM's ones?

Good morning nice handle print 👍 greetings Pieter

@ELEGOO: A handle on the cover should be there from factory, just a small one... 👍

Did you post the file for the handle anywhere I would like to print it

Great video my dude! I'm thinking about pulling the trigger on this one. I've never had a 3d printer before...recently got into Warhammer 40k minis. Any thoughts?! What should I get with the printer? like there's any other expensive tool that i need to have a nice and easy place to print my minis?! Thank you, keep it up good work!

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 😞

good, great video

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.

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

Finalmente um avanço tecnologico que nao é resoluçao de tela. Acredito que finalmente valha o upgrade da Saturn 2 pra esse novo modelo ultra. Espero que comece a vender logo no aliexpress.

Question: what liquid did you cure the print in ?

hello sir could I get saturn 4 Ultra print setting sir

How much does the open lid extend behind the unit?

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.

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

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.

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.

Love the handle, any plans on sharing the files to print it?

its almost perfect... could be a lil bit higher and also could have a heated vat ... im really excited to see the saturn 5 LOL i think the Form 4 printer added some nice features other companies will also use...

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

What's the purpose of curing in a liquid? Is that water or IPA?

I would have mounted a strain relief piece on the rear of that handle.

when was this video made, the resin used expires on 07/23/2022

Why cure in water?? Is it to stop warping?

Where did you get the Drip bib

Where did you get that drip bib??

Hy have ball screw ?

フリップアップカバーを開けるために、本体裏にはどれくらい空間の距離が必要なのでしょうか？

Just waiting for the 16k saturn.

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?

Man... I feel like I just bought my Saturn 8K and now I need to buy a new printer? Fine! Just... uh.. don't tell my wife! :D I don't think the handle looks bad exactly, but I feel like a clear film on the outside of the lid would have worked just as well... maybe some helicopter tape or something similar?

Nice

More reviews like this and less uncles presenting new products please!

I pre ordered it yesterday...man 400 only for this?! My first SLA printer was the M5s which is kindadisappointing. Really hyped for the Ultra 4

That mod made since

ive, never had those holes at the top, and i have the first elegoo mars.

Why do you cure in liquid?

My bet its that in the Saturn Ultra 5 they are going to drop this tilt system. Like formlabs in 2014. PFA exist since Saturn 2. That holes can be reduced and almost eliminated using rest before print.

Very good, I was curious about the upgrades compared to the Saturn 3. I hope the election starts selling soon in Brazil too kkkkkk

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!

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

oh what a bummer that the build plate doesn't fit in the existing mercury x wash station!! great vid tho.

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.

Gran mejora añadir el asa.

Never once seen those holes on any of my prints.

Impressive. AI camera? Almost Space Age.
