My Elegoo mars 4 ultra arrived yesterday, really quick delivery but will be watching a load of videos and testing settings. So it’s nice to see what different people use to help me tweek it!
The Shiney print (your siraya tech resin) is not properly cleaned, still had uncured resin on it when you cured it. If it's not a matte finish after it dries from washing, wash it more.
I am anxiously awaiting a comparison between the Mars 4, 4 Max, and the 3 Pro! I have an FDM printer that I use a lot for terrain and some minis in my D&D game, but I am waiting to pull the trigger on a resin printer for those crispy details. I won't let Millennium Games continue to take all my money! 😅
Just out of curiosity im torn between the mars 4 and the mars 3 pro as the mars 4 is only about 25 bucks more with pre-order. Does the price incrase for the mars 4 after the pre-order is over?
So Fauxhammer was saying the ACF was causing exposure issues with the photon m5s. Are you seeing similar issues with the Mars 4 Ultra. I am thinking of buying a machine with one of these ACF films as well as upgrading some of my vats to the ACF and I was wondering if you were seeing exposure and bluriness from the ACF since instead of being clear its more translucent.
I saw that same vid and was wondering the same thing. We'll have to wait for Faux to put up his vid where he switches out the ACF for a NFEP on teh M5.
@@matineyang I don't know. I want evidence from multiple sources. And with Uncle Jesse saying it's not an issue. The video needs to be incontrovertible or more content creators need to come out and say ACF is a problem
@@MaheerKibria I’m sure there will be plenty of people that will test the results between acf and nfep. Just have to wonder if those test will come out before you decide to get the mars 4.
@@matineyang I am more interested in the ACF as stand alone film because you can buy it and install it without having to get an entirely new printer and I am happy with the detail i currently get so if this ACF gives me no noticeable loss of detail but faster print times it is worth spending the $40-100 dollars it costs to get it per printer. Kind of how nFEP was worth getting without having to buy a brand new printer for the speed up and fewer failed prints.
I think we're hitting diminishing returns in print quality. Not really a big jump from 4k, which is ok, 4k resin printers of this size still produce excellent looking prints, the big selling point of the Mars 4/4 Ultra is speed and not necessarily increased print quality. I think LCD screen resin printers are at their limit, continuing to increase resolution is not the answer moving forward (unless we're talking big printers). Im sure the Mars DLP still has a slight edge over the Mars 4 in print quality despite only having a ~1440p projector whereas the Mars 4 has a 9k screen. In fact DLP is where it's at, you can get prints that approach injection molded parts if you max out the AA without sacrificing quality. 4k DLP printers will be something to look forward to.
you can technically add more dlp modules and merge together the image to get more effective resolution but while i like DLP technology as well it looks unable to complete because texas instruments doesn't seem to care and they have monopoly in the technology
Bit of a late reply ... but thanks for saying this as I'm presently look at the Mars 3 4k or the Mars 4 9k as my first resin printer. I'm getting so overwhelmed watching too many videos. The price difference is only AU$50 though.
I worry about the carbon filters? they seem kind of gimmicky. Has anyone really done testing? It's a serious question because respirators for paint booths have maximum use time of 8 hours once opened. And even sealed carbon filters should be used within 6 months and not sit on the shelf longer. So how long have they been on the shelf before shipping? I would much prefer venting outside for safety?
You can enable and disable the sounds on all of the Elegoo resin printers. I have it enabled on mine so it beeps when it starts and when it finishes printing.
@@UncleJessy It's kinda in an odd place if I remember correctly. Like where the firmware version is listed, etc. on the older models. I've used it from the Mars 2 up to the Mars 4 Max.
@@UncleJessy That would be awesome! And also insane haha. Definitely keep us posted on that! I kind of wished their lcds were interchangeable and or upgradable. Like instead of a 9k LCD with the mars 4, give me a 8k LCD that I can use to upgrade my mars 3. As the elegoo mars 3 is hands down the best printer for that price and imo the quality!
@@LS3D_Printing From sales perspective, should these upgrade kits exist, every kit sold gives them -1 in sales of the new printers. So, nope. Not gonna happen
I actually prefer the ball joint build plate. Man. I want that faster print time on the Ultra but it loses print height and has imo a worse build plate mechanism...I guess I could get the regular 4 and upgrade the release film.
Do you clearly see a factor of 2 in printed resolution compared to the Mars 3 pro's 35 um pixels? Or is more like 10-20% better? The reduced print width of the Mars 4 is a problem for me (smaller than my Mars 2!!!), so Im considering the Mars 4 Max or Saturn 3 as an upgrade from my Mars 3 pro - they have same print width, but higher res for the Saturn, but not clear to me it is worth the extra bucks.
What is your process for getting these fast resin profiles going? I've tried making some faster profiles, but it seems like the tolerances on cure time are razor thin when you get small layers and fast movement, and hit a point where its just not possible. In the end I stick with basic .05 or .025 depending on the model and dealing with the up-to-8hr print times.
1. It's finally warm again so that takes out one big factor with cold temps and resin settings impact 2. I will usually run a bunch of smaller exposure tests/small print tests to see whats working and go from 180 lift speeds to 240 to 300 and see how the prints continue to look with the exposure setting I'm trying to work with. 3. Siraya Tech Fast is super low viscosity which helps a lot when trying to print faster
This may be a stupid question but assuming the settings for lift distance and speed, layer height, exposure time etc all come from the slicer software, how is it possible they can print at different speeds? May be a silly question but I hear about printers being fast but assumed it’s down to the resin and what you can get away with. I could believe that a ‘fast’ printer can get the same level of curing from a shortened exposure time across the same resin maybe but when all settings are the same,what’s making the difference?
Motor strength and lift speed plays a role. The 'Mars 4 Ultra' uses a vat with ACF film, that releases the print from the film ~30% easier, so the motor has a easier time pulling the print off at each layer. If you look back you can see its "foggy" and not clear like glass at 1:57 This will in turn make your prints less sharp as the light from the printer is going through a diffused film, hence why Jesse is having issues dialing it. You can just buy a normal replacement vat film to get even better prints, but they will be printed slower.
You showed a protector on the screen (as it is also written on the Elegoo website), why is there no protection like yours in mine and that of other reviews?
How long does it take to get the printer. I ordered the elegoo 3 ultra and I got the resin and the film but no printer. And know one has responded to my emails
5:47ish... Newer to this and wondering how would the base take so much longer than the figure? It's just a base... it could be completely hollow and should take less than an hour imo based on the dozens and dozens of videos I've watched about these printers. Right?
Personally never had any issues with a ball joint mount so the quad bolt just adds a cleaning issue for me. Auto levelling.. not convinced as if it's not working properly it may be difficult to correct .. at least manually I'll get it correct and tweak it if needed. Again I've never had a levelling issue wrt resin printers especially compared to FDM resin levelling is utterly trivial IME. Things I would like incorporated are larger screen interfaces, Magnetic build plates as standard, vent port for extraction & Vat heaters.
I was buy the elegoo mars 4 ultra. Is coming together with usb. I try to transfer some file with ring in usb. But dosent work? Can you help me what i can do it please?
@@UncleJessy I've got a Saturn 1, and my print fails are higher than when I had a smaller epax printer... Hoping the smaller size keeps me from the mad dash to fill the build plate and fail to support the extra models well.
It's about time Elegoo moved away from that silly ball joint plate mounting system. Good to see the Mars 4 Ultra has a better option. Hopefully, they'll do the same on the Saturn 4 if/when it comes out. I'm in the market for a 10inch resin printer.
i don't know which one is better, there are people in the comments here complaining about the new mounting system; in theory ball joint would be the most ideal, but in practice i guess it's not?
i love my mars 3 pro but recently ive been getting a lot of failed prints. im getting a lot of print not breaking away from the fep i can even hear it creaking. ive gone through 3 new feps trying to install them tighter hoping it will release easier. is there any tips you can help with
Hey, I think Ultra plate with these 4 bolts that goes into the resin is huge step back in terms of design, I really like the simple design of a single point of contact between the plate and the handle like the non ultra models and all the old models
What do you mean with exact same settings? Please be more specific because if you compare fillament printers running at the same speed they will just print at the same speed. What settings are you talking about, is it movement speed? exposure time? Do they all have the same lift height? These are important things since you can easily increase printing speed with resin printers by increasing movement speed and decreasing lift height but that could cause random faults to occure. I can print at super slow speeds on my P1P and at optimized settings on my Ender 3 and make a comparison stating that at the Ender 3 beat the P1P but that would be very misleading.
I listed it all on screen... everything was the exact same. Resin, layer height, exposure, Bottom, waittimes, lift heights, lift speeds, exposure settings, the exact same profile was used for all 3 machines
@@UncleJessy How can one printer be faster than the other then? Serious question, like if they are programmed to do the same movements at the same speeds and intervals, how can one finish faster than another?
@danfenzl6180 what I'm trying to get at is that they should have all finished at the exact same time with the same settings but the faster printers should be tunable to be faster. In this case it's simply of software hack that elegoo does to their printers but it doesn't say anything about the actual speeds the printers can actually get to. I would have expected more research and explanation as to why the newer printers are faster and looking at how big that difference actually is (and I am speculating that they will all preform roughly the same). A dumb software hack where a printer interprets a 10mm/s speed as 5 mm/s so it will go slower should not be accepted and reviewers should do their job and do research and call out shady manufacturers for playing these kinds lf software tricks. If there is a genuine reason as to why the newer printers are faster for the same settings that can not be achieved with a software change to the older printers I am all ears but at the moment I don't see any reason to believe that is the case
@@VTeslaV Best guess on why they are faster or slower will be acceleration, if you set a printer to lift at 240 mm/min when it starts from stationary it doesn't jump to 240 mm/min its ramps up the speed, if due to the different release films Elegoo have decided that faster acceleration is possible that may explain the print speed differences. Additionally there maybe waits/processing times which are not directly controlled by the slicer settings but are different between the printers which can add or reduce the time a print takes.
What I don't understand is that the saturn ultra just came out with the 12k resolution on the saturn 3 ultra. Why couldn't they put the same tech into the Mars 4 ultra.
Hello Jessy kannst du mir bitte dein Setting schicken vom Elegoo mars 4 mit Standart Resin Grey bitte verstehe das eingeblendete Setting in diesen video nicht lg Norbert
Its not diminishing, its just gone. 12K sounds nice, but we don't have enough control over the light bleed and how resin cures to be able to manage the micrometer differences between 8k and 12k resolutions.
the problem here is Elegoo sacrificed its 18um pixel size by using a ACF release film which can significantly speed up the printer but also softens the print. it seems that a sub 20um is probably the threshold for resolution that humans can see but considering this is the first "cheap" printer to get to that size and that companies aren't focused on resolution as much as they are speed, we probably have another few generations before we hit the limit...
The reason the Ultra had worse definition wasn't your settings, it is the ACF film that causes the "softer" details. It seems that Elegoo made a 9k resin printer then gave it the effective resolution of a 4k printer with the ACF film so that it could print faster... why would a company do this? mostly to add keywords that uneducated buyers will look at, like how many k's of resolution and how many X faster it can print. I bet if you swapped in a normal FEP you will see a difference.
@@UncleJessy basically you take the contours of a pancake (regular) lens, but chop the angles up and segment them so you don't have to have the full thickness of a traditional lens. If you've ever seen those credit card sized magnifying glasses for sale at a walgreens or rite aid, those are fresnel lenses. I think the actual reason they're called fresnel lenses is because fresnel is the guy who discovered something about light reflection and refraction being all dependent on the angles within prisms and not their thickness or something like that
Picked up a Mars 4 Ultra last week. Cant wait for it to be delivered. It looks great.

Man... I don't know. Those layer lines are a bit disappointing. It's hard to know how well they really print without seeing proper exposures.
I'm surprised he didn't mention the fact that the 4 had a smaller build volume than the 3.
really, it does? That`s terrible!
In regards to skin safety, Siraya Tech Blu is ISO certified for prolonged skin exposure.
The Shiney print (your siraya tech resin) is not properly cleaned, still had uncured resin on it when you cured it. If it's not a matte finish after it dries from washing, wash it more.
Would you help it dry with a hairdryer to make sure you spot those shiny spots? Or just leave it out. Just wondering how it works with UV curing

No one cares about speed at the cost of quality. Can we stop making speed such a bragging point?
Too right, I'll happily take ten hours for a couple of ork boyz if they're going to be ultra crisp models I can then use for years
I do
maybe speed is important for somebody who sells multiple items in short time to sell? 😅 just guessing 🤷♂️
its a shame that its samller than older printers. i think that 9k its waaay too much for a such small sice print

Not down here in Australia. Thanks UJ for repping us Lye-Chee eaters!!!
fresnel is pronounced fre-nel
It's a french dude's name
I still have no idea what it fully is... and too lazy to google it hahahaha
@@UncleJessy basically you take the contours of a pancake (regular) lens, but chop the angles up and segment them so you don't have to have the full thickness of a traditional lens. If you've ever seen those credit card sized magnifying glasses for sale at a walgreens or rite aid, those are fresnel lenses.
I think the actual reason they're called fresnel lenses is because fresnel is the guy who discovered something about light reflection and refraction being all dependent on the angles within prisms and not their thickness or something like that
Sorry, but some of these prints look terrible and I know the machine can do so much better than that…you really should check your settings.
