Elegoo Saturn 4 Vs Anycubic M7 Pro - Isn't it ALREADY OBVIOUS?

[@chrismatney639]

If you are considering an S4U for your first resin printer, don't think just buy it. I was afraid of the learning curve of resin printers, but the S4U is so simple, it was hard to mess up. Right out of the box it printed like a dream. Other than a few software crashes caused by Chitumanager I hadn't had a single failed print until the FEP started to go last week, and it has been running almost non stop for a few months. I can say without a doubt it has been one of my best hobby purchases ever.

[@testermonkey2304]

yeah ive had the same experience with mine. So worth it. also the chitubox heater is miles better than the elegoo heater

[@chrismatney639]

@@testermonkey2304 I got the elegoo heater, which just arrived last month. But I haven't seen a need to install it. I keep my printer indoors and live where it is warm year round. If the temp monitor on the printer can be believed, it never goes below 20C.

[@OldSkullSoldier]

Double-deck plate pushed me away from S4. But I bought Saturn 3 and it is a great printer! To be fair: how often do you need to level your bed? Once at start and then only if you incorrectly remove the prints (hint: don't remove prints without removing plate from the printer). Biggest concern with speed are always layer height and type of resin. Any warping resin needs to print slower, same if you want good quality: 50um layer makes no sense if you need to use sub 25um piksel printer, as your cubic piksels become 50um in height, which become 59um in diamater. Use 25um layer, to get 40um diamater, but then curing time affects your quality a lot... But still: I can finish within one day prints using elastic/tough resins and this is absolutely enough.

[@scottg6919]

I recently purchased the M7 Pro. I chose the M7 primarily because of the heater/circulator. Also, cleaning the Saturn build plate was something I didn’t want to deal with and concern about resin getting into the tilt mechanism. My first print with the M7 was the was the RERF calibration with Anycubic ABS-like PRO 2 with default settings with temperature around 24 C. For any who don’t know, this prints 8 separate models numbered 1 through 8, starting from a base exposure time increasing in .25 second increments. 3 of the 8 models failed to adhere to the build plate. These corresponded to numbers 4, 6 and 8. The others (1, 2, 3, 5, 7) were acceptable. These corresponded to the right side of the plate closest to the machine which appeared to be a bed leveling problem so I went about leveling the bed. The guide that comes in the box did not have leveling instructions for some reason. I did find instructions on the usb drive, the anycubic wiki, and a video on Anycubic KZbin. Problem was the instructions were slightly different on each source. For example, in the video, after the steps where the plate is homed and lowered one millimeter, text appears in the video with a ‘tip’ advising to ‘lock the screws’. This does not appear in the M7 PDF manual or the M7 Anycubic wiki leveling guides. The video, which otherwise demonstrates every other step in the leveling process, does absolutely nothing I can associate with the ‘lock the screws’ tip. Later, toward the end of the video, there is s the instruction to ‘tighten the screws’ which doesn’t make sense if you had ‘locked’ them previously. After several attempts following various permutations of the instructions, I finally got a ‘complete’ level test, which I assumed to mean the leveling had been successful. I should have run the RERF again (live and learn) but instead set up a longer overnight print using over 400ml of resin which also failed to adhere to the right side of the build plate closest to the machine. The print did complete but because the right side of it was hanging off the build plate, it was warped and unusable. Following this, I thoroughly scrubbed the build plate in case I had missed any residue from manufacturing, more obsessively went through the leveling process again and increased the bottom layer exposure from 25 seconds to 40 seconds. Since then, things have been working working great, however since several things were done at the same time to resolve the issue, I’m not sure what the original problem was. I’d be interested in knowing anyone else’s experience.

[@ramblingbadger]

Have to agree that the thought of resin getting under the vat on my S4U is scary but hasn't happened yet and I am really clumsy. The plastic bib is really naff but does seem to work... pretty sure it will crack at some point though. Also, many thanks for continuing to wear clothes during your time lapse shots.

[@Pisaebbasta]

It s something like a year that i m in the world of 3d resin printing. i started 2 years ago studying over and over all the reviews video so many times that when i finally bought my first printer (elegoo saturn 8k) i was more skilled then people i met while i was looking for a second hand one. For all the beginners falling in the same loop: you have to try and see to learn. I made a lot of mistakes, i spent a lot of money in resins, wash and cure etc... You doesn't need the better printer on the market in quality because when you'll learn it wont be anymore. So go cheaper and improove. All you need is patience, a lot of patience, a lot of space and a lot of time. I can finally say that, after a year using the saturn 8k, my new saturn 4 ultra is another world. it s really really simple to use; 'Cheap'; Fast; and it has a small risk of fail. I think it s all you need to start other than FauxHammer videos ;)

[@Gregatron13]

The Saturn 4 Ultra had me at the tilting vat with fewer settings. I'm looking forward to the simpler slicing process.

[@FauxHammer]

Hopefully one day

[@Bobby11]

Yea i have been printing a fair bit on my S4U (about 7 litres) so far, and almost all prints filling the plate, and so far the film looks in great condition. The only negative with the tilting vat and noticeably faster printing is that you go thru alot of resin fast 😀 ive also noticed that the dimensional accuracy is really good. Maybe because of the gentler peeling forces. So far im impressed.

[@walterramirez3287]

@@FauxHammer I Just ordered the S4U using your link. Is my first printer. I don't like the pump or heater on the M7 pro, looks complicated. I also live in a hot weather area so the heater is not a must. I can clean the build plate on a plastic bin with alcohol. Thanks once again for all your help.

[@AntiVaganza]

@@FauxHammer Replying here as you may actually then see my comment: You said you don't know anyone printing at higher than 50um... Well, you don't know me, but I print almost everything at 75um. Why? Because I am not printing miniatures but functional parts which are getting a light sand anyways. So, I end up printing way faster and I don't burn out my screen so fast (I am on my third soon - yes, I print a lot of parts). No shade on minis but I think a ton of people not into minis also watch your channel;) The main reason I wouldn't print even higher layers is that the light can't "punch through" and cure well enough if I go too high and some of the features still need smallish steps. So, for me, for my parts, for my particular opaque resin I print at 75um. If I printed clear resin and my parts were ok with a bit of stepping, I think 100um would still cure and fuse well. Now, I had to chime in because you have quite the reach and I wouldn't want people to think that 50um is the highest you should ever go. It's a horses for courses thing. And while I respect your thoughts a lot and you cutting through the BS, I am also wary of wrong "knowledge" doing the rounds. Like back in the day (oh, still nowadays...) where influencers and manufacturers still preached you have to print initial layers at 25-30secs. I print mine at about 10-12 secs (on a resin with a 2.3sec normal exposure length) and could probably go lower. I sense you do the same:). Yes, I am blessed living in a place where temps aren't an issue. No need to build up heat by blasting the LCD any longer than you absolutely have to as it is likely to shorten its lifespan. Speaking of which, here's an idea for an in-depth test someone could consider picking up: I'd love to see someone put a temp sensor inside the printer during a print and add that info - especially in comparison tests. E.g. between these two while I do think I will have a tilting bed in my next printer, if another one ran much cooler, that might tempt me. Actually, the marketing material for the Saturn 3 specifically talked about better cooling of the internals - whereas that seems to gone (or a given) on the 4 now. Might just have been PR Speak or might be that they do know it can be an issue but they penny pinched and dropped whatever was possibly better/more expensive on the 3. Not sure as I haven't seen the insides of any of them.

[@AntiVaganza]

An add on thought. Fillers are a thing in engineering resins (and I guess in a lot of others). These can settle on the bottom during a long print and it can actually mess with your print as they make the resin more dense and you end up under exposing the end of the print - and you have less filler, less strength at the end, too. These can be real issues on a long, structural print. So, even though I though the heater on the M7 was silly, maybe that pump would help keep the fillers suspended. I am hoping a tilting bed would do the same. Yes, I know, I am an outlier. For most of what people print, this will never be an issue;)

[@sxty8goats]

I use a self built chamber heater on an M5. It works very well. I use it for Sculp Pro ceramic resin at 30C. Raise the bed the top. Put the bottle of resin on the printer, start the heater and close the lid. Let it run for 20 min or so to heat the bottle. Shake the bottle a lot (ceramic). install the vat, fill and print.

[@walltar]

My Saturn 4 Ultra arrived just Yesterday... Thank you for all your videos about it.

[@theHadmir]

I am loving my Saturn 4 Ultra. the tilting vat is something every company should consider, reducing those peeling forces is huge, I have had only one print failure and it was my fault when doing the supports. (didn't use enough and the print pulled off the supports). One thing I would say about it, though it is more to do with their sold separately heater, is that it needs a different way to attach it. attaching to the vent hole with a plate doesn't work if you want to run an exhaust hose to it. I have the heater 2-side taped to the back above the camera which blocks one of the intake vents on the heater (also upside down). not exactly a perfect solution. it's summer here right now so it's not a huge issue, but living in Canada, that chamber heater is going to be put to the test come winter.

[@mehrdadhaghighi5140]

I love the Saturn 4 Ultra. Quick tip, if you are printing moulds with square corners, turn the model by 45 degrees to decrease the pulling force even more and use the high speed without any print speed or quality.

Hi FauxHammer, I love your videos and the Saturn 4 Ultra is a really appealing machine with the highlight being the reduced settings complexity. I live in Victoria, Australia and would be putting this machine in an uninsulated garage. It is consistently well below 20c here for 6 months of the year though. I would love to see some discussion about heating solutions and how effective they are, particularly things like that greenhouse-like enclosure you mentioned and just how useful that is vs shelling out for a more expensive device with proper heating. (the GK series seems to have a massive austalia tax on it compared to the elgoo/anycubic devices).

[@Immolate62]

For those of us in milder climes, the heated vat system is a bunch of points of failure and a major PITA for little benefit. For those of you in the chill zone, the benefit might be better, but I think you'd get by with a small space heater inside the lid. You don't need hot resin. You need not-cold resin, and that's not that great a challenge. For that matter, someone should put together a build using a small heated bed made for FDM printers to mount on the lid along with a small power supply outside. Super cheap from Ali Express.

[@FauxHammer]

All fair points, well made

[@JerryBWagoner]

I know the little space heater thing is not the "optimal" way to heat, but I was having issues with my basement being too cold, and a $30 generic under-lid space heater solved the problem.

[@Vizeroy9]

Well, I need 2 things. 1) warm resin 2) simultaneously working fumes extraction. Current heaters for inside the printers usually block the vent port. Extracting the warm air directly makes heating rather pointless.

[@fluxcapacitor]

@@Vizeroy9 I concur about the Elegoo air heater being pointless while extracting fumes at the same time, as it would immediately extract hot air before it could warm the resin. The only printers that I think can do both heating + air extraction together are those that heat the resin from below the screen (like the UniFormation GKtwo and GK3 Ultra) or those circulating the resin through a dedicated liquid heater (like the Anycubic M7 Pro). But Air Heaters? Nah.

[@MaheerKibria]

For me now that you have A RERF like feature that is arguably better than what anycubic had makes the Saturn the clear winner. The resin pump in the vat with heating is an interesting idea not for heating but for possilby keeping stuff like mica powder from settling. but no one has tested it so who knows. Chamber heaters work great. been using a DIY one for a few years and ever since i started using it the results have been very consistant. And my printer is out in the garage and I'll print in winter. The volume you have to heat us so small that even without any insulation the a small ptc heater will easily keep the chamber above 25 C. The issue ends up actually being thermal runaway rather than lack of adequate heating in my experience.

[@Gravity_Fish]

The S4U is so dam out of the box easy. I've got the elegoo mini heater as well. It arrived later than the printer. I'm in Aus and it's winter, I did have issue after issue till the heater showed up. Now every print is nailed. All without tweaking ANY default setting. (Overnight, temps in that room are about 11C) Just leave it running for a bit before you start printing and it'll warm up everything under the lid well enough.

[@extreme-3d-customs]

I have 4 any cubic m7 pro printers and I have been running them nonstop so far for my business and they work great. had a little issue with firmware but so far it heats resin great every time and my layers are down to 1.2 sec with Syria tech resin, and it works great.

Everyone says its super bad but nobody seems to you use a suction hose. 3) The Saturn 4 is over 100€ cheaper here, doesn't the M7 with its more settings have more options to 'perfect' the prints? If not it looks like a no brainer to take the Saturn over the M7 since its only upside is the heater.

[@mscrawford87]

1. Yes. After washing. It's very important. You well never get ALL of the resin off in the wash and when you expose to UV, whatever is left on the surface will be cured. It doesn't take long, only about 3 minutes max usually. Just get a cure and wash station, they are very much worth it. 2. Its bad. It will give you a headache, requires proper ventilation, and is bad for you. Wear a respirator. Not an N95 mask, a P95 or up. People will downplay this, and they are flat out wrong. I have a background in chemical engineering and now work in the health field as a Critical Care Registered Nurse in the USA. From both fields, trust me. Your lungs will thank you in 30 years. I see guys doing videos without PPE and it blows my mind. 3. Anycubic usually slightly outperforms elegoo with most of its products, but elegoo is very much catching up. The physical mounts of your build plate etc. is a bit better designed in anycubic models i.e. it's easier to hold, manipulate etc. In my opinion of course. Anycubic feels slightly more premium, and looks anesthetically a bit better, but again that's up to subjective opinion. Happy you are joining the hobby! Jist be safe, and please, correctly dispose of the chemicals you use when printing! (The resin and the IPA).

One thing to note that you missed in the revo review. The vent port is proprietary. It would be roughly equivalent to a 77mm fan, which is a nightmarishly bad choice. If you want to use that same hole and redrill the mounting holes for almost any fan you'll be trying to drill them within a few mm of the existing holes. Which leaves adapters, which there currently are none. They also use #4 screws for the plate, which are substantially smaller than standard mounting bolts for fans. It's just fun the whole way around.

[@costelasleontin]

Now after using an M7 Pro I can tell you that the actuall high speed of this printer comes from the fact that using the advance settings you can set a slower retracting speed for the platform till the film peels of and you can set another much faster speed for the rest of the retraction distance (after the film peels off the platform still needs to be raised so the resin can fill up the area where the layer got cured) and also there is another feature that uses AI to check with the builtin presure senzore at what distance the film peels off and adapts the distance and the speed of the platform dinamically after the film peels off (but yeah there are reports that this feature doesn't works properly in certain situations ex. some high viscuosity resins). I think Uniformation printers can also setup 2 speeds for the platform retraction based on their Chitubox profile. Also the screen luminosity is probablly higher than other same size printer models considering the curing times given on a few resins (for which I have seen the printing specs).

[@FauxHammer]

Pretty much all printers have 2 stages for lift? And I don’t believe for a second that Anycubic have ben smart enough to have dynamic lift speeds based on force. If they did then it would be something to really shout about and would fork with PFA too

[@olahf8490]

I bought the S4U because of the flip up top and the tilting vat. The Halot mage was my first personal resin machine and it was good but the S4U puts the Halot and my office Form 2 and 3s to shame.

[@chaver28]

just wondering how is the fumes of resin printing? get my first printer soon

[@Vizeroy9]

Always use a respirator mask with filters for VOC. Resin is rather toxic. I always have them in a well vented room, which is an "always respirator" zone.

[@chaver28]

@@Vizeroy9 i was going to attempt to link it up to my extractor fan and hope that it will help with the fumes as i only have a small property

[@chrismatney639]

I use an extraction system with my S4U and it works great. When I first got the printer I ran it without the extraction system for the first 24 hours and I could smell the fumes in the room. After hooking up the extraction system I can't smell a thing. Even if I leave the lid on the printer open, as long as I am not standing directly over top of it, there are no fumes. I get far more fumes from the cleaning solution. I'm considering moving that inside an extraction tent.

[@Vizeroy9]

@@chaver28 do this but still wear a respirator when handling and cueing the parts - and always nitrile gloves. Oh, and never dump contaminated fluids down a drain. That stuff stays in nature for a looong time, and is toxic as heck.

[@alienmorf]

Are stay in the same room while printing? Not afraid VOC things?😊

[@Old_Wizard_Minis]

Not my 1st video. More like my 100th. But good job treating this like it could be someone's 1st.

[@FauxHammer]

Thank you. Thank you so much! The amount of shit I get off commenters telling me I repeat myself is painful. Thanks for understanding that I need to assume this could be anyone’s first video

[@esimpson2751]

its my first

[@antoniomromo]

How I wish the Mars 4 ultra's tilting vat and reduced slicer setting would merge with the GK2 build plate design and heating vat.

[@Convincing_Reality]

Wait, the heater for the Saturn Ultra 4 occupies the same space that you'd use for extraction? That seems like a really inconvenient compromise.

[@FauxHammer]

Sure, but why would you use chamber heating and extraction at the same time anyway? You’d just suck all the heat out?

[@Convincing_Reality]

@FauxHammer Aye, I was thinking that right after typing it, and have fruitlessly spent the last 10 minutes trying to think of a seemingly nonexistent solution which integrates both. I guess the issue then is that given we don't want toxic fumes kicking about then an external heat source seems more advisable. Is that what you'd suggest?

[@FauxHammer]

@@Convincing_Realityyou want a vat heater ideally. You may be pissed to know Elegoo are about to announce a new Saturn 4 ultra with a heated vat! But there’s thermalvatband who make a stick on vat heater. But I’ve never tested one. Some people use a thermal bad for heating alcohol jars. Like @battlebrothersam

[@AsparagusX]

Hey Ross, where are the orange stains on the resin prints coming from? You can see them multiple times throughout the video while still on the build plate.

[@FauxHammer]

it was the drops of orange ink i put in the vat to show the resin moving for the heater

[@AsparagusX]

@@FauxHammer Thanks! Great videos, as always!

[@JohnDoe-ot5ir]

I went with the M7 pro and I'm very happy with it. The heated resin , larger print area and mobile app support was the deal breaker for me as well as I didn't like the design of the S4U, that allows for potential or more like a WHEN not IF resin will spill into the printer. I also don't like the design of the s4U build plate. Looks like a nightmare to clean. I'm sure the S4U is ok but not for me.

[@FauxHammer]

An absolutely perfect comment! YES!!!! More people should be making the right choice "FOR THEMSELF" rather than just following people's direct opinion. You and I have different wants out of a printer and you chose what is right for you. good job!

[@Bobby11]

I think in print farms and people not changing resins often the pump is much more useful.

[@timstoth4271]

What are your views on wham bam flex plates with resin printers.? Watched a LOT of your videos and saw a few bust prints on Sons of Anarchy characters and wondering if you designed them as I'd love these on my desk once I start resin printing.....

[@tyrannicpuppy]

Push that big chunk down coz this will be quicker up here. Question, why do you always pour the resin onto the top of the plate? I'm under the impression that resin is toxic and dangerous, so surely adding an additional drop and the potential for splashes is a bad thing. So I'm guessing that there is a fundamental reason for doing so. I see it in all resin printer videos, but no one has ever explained why. 100% agree that quality is less important than ease of use for me. Ease of use is what is still holding me back from buying a resin printer. They're definitely much better than when I first poked my nose into the space. But until it's as simple as the current range of FDM printers (or as near as is possible with a toxic print medium like resin) I'll still be happy having a few visible layer lines on my FDM prints. I've no real NEED to print anything as perfect as the stuff you show off in all of these videos, but I've definitely been bitten by the bug and I keep my eyes open for the day that resin printing becomes as easy as FDM for me.

[@thepeakoflife]

Put bottle of resin under and out. Pour into Saturn with heater. Perfect print

[@FauxHammer]

Pardon? under and out?

[@haukke]

My resin printers are in my basement and i have been using chamber heaters since i bought the Voxelab 2K printer 5 years ago. I personally have had zero issues with either the heaters that i made or bought. Would i have liked my vat to be heated....yes. Is it a non issue....yes. I live in the Northeast of the United States and it does get cold and my basement is not heated. I love my Saturn 4.

[@FauxHammer]

Thankyou. very useful input and it;s greatly appreciated...

[@Dj_Medic]

Hey I was wondering should I get a screen protector for my Saturn 4 Ultra?

[@CptnAwesome]

I does not look like it, but there is already one on the screen. So no need for that. It already saved my life when the build plate fell on it while moving the Printer while forgetting to fix the built plate.

[@Bobby11]

As much as i am loving this printer, so far the only time ive bothered with the camera is just because i can. Its a shame Elegoo dont have an app to monitor the prints. Because so far the camera is more of a trinket than anything actually useful.

[@3dpathfinder]

Ive got the Saturn 4 Ultra and I guess ive got need to play with the settings more because prints aren't as good as I hoped . I would like your recommendation for a Large affordable resin printer. Been thinking , Jupiter , or maybe the Gk3. Is the GK3 worth the price difference from the Jupiter? Im not really printing Extreme detail items Id more be printing Prop cosplay stuff, really want to slice a helmet and resin print it

[@FauxHammer]

If printing large models, I doubt you would need the detail of the GK3. But the heater could be a helpful addition.

[@Blind_Smithy]

Is a a Uniformity gk2 or a sat4 ultra better then?

[@BioClone]

Any idea on the cons of having higher temperatures? I plant to set it near my PC and it may be rendering for long periods... would be 25º - 28º room temp be ok?

[@3dpathfinder]

another question..on the saturn 4 ultra, I use lychee pro , alot of the community profiles for resin still have retraction settings, do i need or can i get rid of these? As im watching yours print i notice that the build plate has no retraction and mine does do to these community profiles

[@FauxHammer]

They will just be ignored by this machine

[@zenlord09]

When you say the S4U is fast, how fast are we talking? Do you have a comparison of the same miniature printed on the S4U vs either the m7 pro (using the same resin) or any other printer like it's predecessor the Saturn 3? Looking at getting one for time saving but I can't find a comparison on how much time it would actually save. Obviously I could load files into chitubox on both printers and see the estimated times but these are always wrong.

[@jaym2381]

A plate of minis (28mm Napoleonic infantry) took 4 hours and change on my old Saturn 8k. On the S4U the same group of minis takes about 2 hours and 20 minutes. It's fast. Incidentally, I found the Chitubox estimates to be pretty close with the S4U. They were less accurate with the older Saturn.

[@Thorrk_THT]

Question: I live in Ireland and my 3d printer will be in a heated and insolated room in the house. Is it still advise to get a heated printer like the GK2 for less failure or am I ok just going for Elegoo Saturn 4 for cheaper and faster printing time?

[@chrismatney639]

As long as you keep the temp in the room above 20C you should be fine.

[@TopTimPlayz]

@fauxhammer by watching your videos you have inspired me to play the game Warhammer 40k do you think you could do some videos on how to play it ?

[@MaxMustermann-hz1jg]

Hey Mr. FauxHammer, i learned from you that the resolution (8,10,12,14k....) is quite a hoax. So the only difference that counts is the speed,but brands lie too at the mm per hour you say. So why dont you pick a modell and test all the printers with the same layer hight and resin to get correct values ?? How fast is a printer realy? How much faster is the Saturn 4 Ultra with its new tilting mechanism compared to "normal" ones? You mentioned that you don´t care about speed, but i bet that isthe question everybody else wants to get answerd. best regards MAX

[@ArtoftheCrowe]

I've got the Saturn 4 Ultra but it's been pretty useless because if the Resin Level sensor. It either needs to be removed or update to force print it cause when it does print it prints great. But even with help from other youtube videos, reddit, and even Elegoo themselves I'm ready to either trade it in for the Saturn 3 Ultra or old yeller this thing.

[@TheCreatorperson]

"What would I choose? I would choose to watch my VIDEO!!!!!!!!!!!!!!" I found that kinda funny

[@jeffthomas3707]

Would love to get into resin printing, but every time I consider it I'm put off by all the heat and ventilation and toxicity issues & requirements. I have a small flat with no outdoor or garage area, so seems I'm stuck with my Ender 3 V3 KE for now.

[@rustumlaattoe]

So i'm not in the market for a new resin printer at the moment, but both of these have deal breakers for me, so i honestly wouldn't want to deal with either of them. The saturn's drippy pain in the ass buildplate and the m7's resin heater that i'd have to clean out all the time.

[@thelordsteel]

in 20:19 you said "if you get Your resin below 20degC You start to having overesposed layers" which is not true... You start having underesposed layers. As a resin warms up it becomes less viscous (i.e. thinner), and requires a lower exposure time. Colder, thicker resin will require a longer exposure time to cure it. Am i right?

[@FauxHammer]

If the resin is cooler you need to expose the layers longer to achieve success. So yes if you just left the time alone. The result would be underexposed. But since you would dial in your resin for your environment temp. You would increase the exposure time and as such. Your layers would be overexposed when successful

[@thelordsteel]

@@FauxHammer am not getting Your answer. Sorry English is not my native. Your env. temp is almost always equal or lower than resin. So if resin temp drops below 20 then Your env temp will be somwhere around that. And will stay that way with small increase during the print. So You will expose to that temperature. This esposition will be longer. Unleass You use heater it will be more or less the same during whole print. Lets say 1 deg is not that big deal and whole print will be at more or less the same environmental constant value. If the temperature jump will be from 20 to 25 deg during print then it may be causing overexposure. but otherwise ""if you get Your resin below 20degC You start to having overesposed layers" is not true.If you will use settings for 25deg and env temp and resin temp is 20 during the print then it will end up with underexposure not overexposure. So that is what i am reffering to.

what about anycube m7 vs m7 pro?

[@awildtomappeared5925]

as for the ACF durability, I have myself got bubbles in my acf and I've seen that from many others, I assume this is the two layers delaminating, this doesn't happen with other fep types so from that alone I consider it less durable. Also there was some stuff j3d shared recently that sugguested that the low peel forces don't last long on acf anyway.

[@krystallitex7596]

could you do a review of the anycubic M7.. not the pro.. this one dows not have the heater and pumps to deal with . this is one i was thinking of getting as when you said about the weight to the vat on the pro, with the heater stuck to it at one end. my thinking is that will be to much for my arthritis hands to hold an tilt. so would love to know more about just the M7. as a disabled artist i have been looking at what to buy and im struggling to find any info on accessibility for the disabled community. like watching you open haygears top looks a struggle for the weaker hands .

[@flagoon]

You are the only reviewer saying that S4U is so much faster than other printers. In first review you said it's three times faster than others (I believe it was some kind tongue slip, or mind shortcut), now you are saying, some print farms are printing faster than preparing the next print. But other reviews are saying about 10-20% faster prints between normal setting and fast setting. Comparing the same print between S4 and S4U, what is the time difference? Do you have information like this? It's not an attack, just an observation and curiosity.

[@FauxHammer]

My comments are based on the time between layers. Consider that this is about 2 seconds to retract and rise back up and prepare for the next later which is about 1.5s exposure time. now look at any normal 10" printer which has a lift and retract of about 8mm. for the first 3 mm this would lift about 1mm/s (ish) and the remaining 5mm at something like 5mm/s So that's 4s up and about the same down. The problem is this varies so much depending on resin toughness and how much you can realistically increase those speeds. Fast resins and ACF films often result in faster speeds, but also result in detail loss. SO the stats I just mentioned are pretty much what I use to ensure success. And there's here's also potential wait times in there too. before lift, before retract, after retract... all of these have value, But anyway. The Saturn 4 takes about 3.5s per layer. Normal 10" printers based on the above settings would take 9.5s per layer hope that helps explain my logic.

[@flagoon]

@@FauxHammer it explains the logic, I was just confused, because other reviewers were showing like 20 minutes faster prints on 3 hours prints. It's nowhere close to even 1/3 faster print. And I understand, that there are different settings, different resins etc, but I assume they take this into consideration while comparing.

[@FauxHammer]

@@flagoon Hmm, I'd love to see someone making tat comparison so I can infer what the differences are?

Mostly love my Saturn 4 Ultra, however I would prefer a build plate like the Mars 4 ultra. I have had a lot of fails on the saturn 4 and cannot adjust the build plate to fix it so I feel somewhat helpless and just re-slice and re-print then it seems to work. I have 2 mars 4 ultra's and have had to change out the acf constantly. It starts to cost. One of my mars 4 ultra's now has just pfa on it and runs perfectly.

[@jaym2381]

I had a bunch of fails on the S4U and Elegoo sent me a new build plate. I tested the flatness of the plate with an engineer's rule, and you could see a bit of daylight between them. Sent the photo to Elegoo and they promptly sent a new plate. No issues since then.

[@lishathorne]

Might look into that, Elegoo has always been fair to me with service.
