What's the Fastest Resin 3D Printer Slicer?

[@UncleJessy]

I will be doing some deep dives into each slicer to show the pros and cons of each in the future. There is also PC Slice Times/Results towards the end of the video!

[@santiagopostorivo]

Another thing jessy. I would like to know if the ipad slicer gives the same quality of print that the other two slicers. And the total size of the file between the three slicers would be nice

[@UncleJessy]

@@santiagopostorivo I do have a file size recap in the video will try to find the timestamp. Shows the times + file sizes. For sure will give a print compare a test and see. I’m 99% sure the prints should look the same but worth seeing!

[@ThantiK]

How about you not hand-wave away the other slicers for reasons like "this only works on this particular printer". -- you said you were going to test the fastest resin slicer, but then you just handwaved others away. Test Vlare, Prusaslicer, and Photon Workshop like the title of the video says you'll be doing. Because those slicers comparisons, even if they only work with those printers, may be enough of a pain point that people want to dive into those ecosystems. It's dishonest to title your video the way you have, thumbnail it the way you have, and then pull this crap.

[@thedivinityman]

I have an elegoo 2k mars 2 pro resin printer, it has not arrived yet, amazon says wed, I found your vid while looking for a slicer, but found some info that you might find helpful, according to Prusa the Prusa slicer will work with any resin and extruder 3d printer if you set it accordingly, I also found a site that gives you every resin capable slicer, I got it when searching if Cura (which I use for my VoxLab Aquila) will work with a resin printer, and it said no but I would link the site, but youtube does not allow that, thank you. Anyways Prusa said their slicer is fully open source and will work with any resin printer.

[@DozenDeuce]

Does Pikaslice work for the Anycubic Photon D2?

[@vaughn.reynolds]

I gotta say, I love watching the Lychee slicer slice... I watch it almost every time. It's like a little zen moment

[@UncleJessy]

Completely agree! Really fun to sit back and watch!

[@Protocol-X]

I was actually surprised with these slicers. For many years I've been using Uniz Slash printers. And even the largest files take under 30 seconds to support and slice, But now I have a large format printer and tried the same stl in lychee. Not only did it take over 5 minutes to generate supports, it took even longer to slice. It really surprised me it is so slow and they want to change fees.

[@kik-was-here]

For the record, it's possible to use Prusaslicer with Chituboard based printers (like the Elegoo ones), but it's less straightforward : you need to first slice in Prusaslicer, which generates a .sl1 file, then you need to convert it to a .ctb file. I've made such a converter (sl1toctb) to work with my Saturn and my Mars 2, otherwise there is the awesome UVTools software that allows to convert between most known file formats (and has tons of other cool features to manipulate and fix files). Why would anyone do that? Because this allows to use resin printers using only opensource software (on our computer, at least ; printer firmware is an other issue). For people who don't like to allow unknown code to run on their computer, it's worth the additional time of file conversion. :)

[@J3DTech]

In my tests I also noticed that the save times are a HUGE issue for Chitubox. Lychee it auto saves and doe sit in 1/8th the time. Im not sure what's up with Chitubox on this. But I'm saving to a PCI 4.0 980 Pro NVME that is 90% free. It also uses 8GB or RAM out of my 64GB and maxes out all 12 cores on my 5900x while saving. When I add in saving time. Lychee: 2:22.33 Chitubox: 6:53.96 980 Pro NVME 1TB 5900X 12 core 64GB DDR4 @3200 When I OC my RAM to 3700Mhz things changed. Slicing 3270 Layers 500MB SLT Lychee 1:50.90, Including save time Chitubox 4:55.77, Including Save time

[@VampireOnline]

I'm glad you added at the end because I was 100% positive it was your Mac... Not that your Mac is slow just that software isn't optimized for it.

[@UncleJessy]

Yeah! Was very very odd. My Mac - Chitubox = Slow / Lychee = Fast My PC - Chitubox = Fast / Lychee = Slow

[@madp3d]

There's a lot of variables here. CPU, RAM, O/S, Wifi speed, model positioning, supports etc. The biggest (and most important) unknown is how they print. Like to see the follow ups to draw some real-life conclusions. Thanks Jessy.

[@vidsurfer0725]

This ^

[@UncleJessy]

Thanks! These were all pre-supported and I used the same set of models across all 3 slicers in each of the tests. Mars 3 - Devil model + base (2 files) Saturn S - 3 little demon wing monsters + a Bust & base (5 files) Will def look into doing some print compares - I'd be surprised if the slicers actually produce different print quality results with the same settings

[@madp3d]

@@UncleJessy Hey, not questioning you. I just got my first resin printer so I'm trying to find my way a bit. Lots of questions. Been FDM for 2.5 years now and have been learning a lot from you. Thanks for the reply.

[@ziomalZparafii]

@@UncleJessy "I'd be surprised if the slicers actually produce different print quality results with the same settings" -> they produced different size of the output - is it because of different format of the file they use? Because if the file format is the same, different size (noticeably) would suggest different slices. (Just a thought, new here, only thinking about a printer so far so lack of experience). Cheers

[@GregorifElfeNoir]

So you printed the files ... but from which slicer ? If one of them is faster and has a lighter end file, are we sure all the details are kept ? I would be really interested in that comparison, since I print for my own pleasure and speed is not the issue for me, I want consistency over all Thanks :)

[@elijahwalker323]

My experience differs completely in that I've never had chitubox not work for me, on the other hand with lychee I've had it crash numerous times. Maybe Chitubox works better on a PC?

[@UncleJessy]

Towards the end I show the tests on PC… for sure chitu runs better on my PC. Lychee ran significantly better on my mac

[@Nu_Chowe]

I just started 3d printing and I find lychee way easier to work with then anything else

[@UncleJessy]

Love that they have community profiles as well!

[@Hateweek1984]

Now that it has been some time how are you digging it? I'm literally just starting myself

[@Nu_Chowe]

@Hateweek1984 yeah I sub now. To be fair the chitubox I didn't use it for very long. I found lychee more intuitive almost immediately

[@deepend9376]

I found that there wasn't a huge difference in slice times on my W11Pro ( i7 12700K, nVidia RTX2060 Super) PC between Chitubox or Lychee. However I did find that Chitubox had a slight tendency to add a small amount of AA at all times whereas Lychee didn't. As a result I got slightly smoother results on organic shapes in Chitubox but more accurate functional parts in Lychee. Lychee also allows me to have the older V2 .ctb files for my Mars Pro and V4 .ctb files for my Mars 3 available at the same time so the paid "Pro" version of Lychee has become my default now.

[@serkanbudur]

Chitubox generally has better surface rendering than Lychee from my experience as well. Guess that makes sense since the boards are from Chitu Systems as well.

[@UncleJessy]

Fantastic info!! Thanks for sharing that!

[@MrCinpro]

You should have what all the relevant specs are on your laptop. I have a tower. And have never really timed how long the slice takes. The blandness of Chitubox just really bugs my aging eyes, lol that said I rolled my Lychee back, because it may now be prettier, it has also introduced new bugs for me.

[@wolffin100]

My question is, the files sliced on the iPad vs pc, how is the print quality 🤔 Thanks

[@UncleJessy]

So far I'm not seeing any differences but for sure will do some more compares

[@vidsurfer0725]

Your hardware is always a factor, and what background processes are running on your computer

[@Martial-Mat]

Without knowing which CPUs you were using, these are considerably less meaningful than they might have been, especially from IPad top PC. Do the slicers support GPU processing? What about multicore CPUs?

[@tadhgd350]

From what I can see, lycheeslicer does not use multithreaded but it does use some of the gpu. Overall I find that it does not take advantage of the avaialble power. Also he said he was using apple m1 max on his laptop and his iPad is apple m1 chip

[@psygonzo7974]

How did resin slicer companies jsut think *subscription* when cura and slic3r are free?

[@santiagopostorivo]

Do the same for FDM. There is a new prusa slicer version with arachne (i dont remember how it is written in english)

[@UncleJessy]

That is a fun suggestion!

[@LisaHarsh]

My question, besides slicing times was the size of the files and how that effected the final print. I mean if pikaslicer is so fast and file size smaller is there loss of detail.

[@kfeltenberger]

What has me curious is not the time (you couldn't pay me to use Chitubox), but rather the file size. If they're all being exported to the same format, with the same base settings, it appears that the Pikaslice is either exceptionally efficient optimizing the data as it exports it to a file, or something is missing. How does the output look between the three slicers?

[@MaheerKibria]

I am not surprised. The beauty of iPadOS is the lack of overhead. Not to mention the GPU is consistent so by using a single unified API it's a lot easier to optimize for than the different configs that have to be supported otherwise. I really want to see if there are any pixel-to-pixel differences between these files and differences in print quality. All things being equal faster is better. However, print quality is king, followed by reliability so the speed is a distant last for me in terms of importance. Also when you do pc you need to include GPU specs. I have no clue what CPU is running and that makes a huge difference since it is GPU accelerated since it uses OpenGL

[@UncleJessy]

Yeah it was wild how quick it was able to process those after slicing with the others.

[@cameronmalchow7597]

@@UncleJessy The question is also, since you are more used to Macs, whether you know how to configure Windows OS to use the GPU with the programs. I know my Windows laptop has both an intel, bare bones, graphics card as well as my nVidia, so the system and programs need to be set to use the nVidia, over the Intel GPU.

[@ilikenothingtoo]

When slicing with chitu I always arrange the parts then save that as a project, close chitu and restart it and open the saved project then slice. I found if I moved anything even the slightest it would go slow as hell or not slice at all.

[@UncleJessy]

Haha yep! I will arrange/hollow/add holes - save the project. Add supports, save the project. Typically all before slicing because 50% of the time it crashes or doesnt slice

[@ThimblewolfArt]

hi, would you mind explaining (maybe in the next video) what exactly a slicer/slicing actually is for those of us who are just getting started learning about 3d printing?

[@UncleJessy]

You know, that would have been a fantastic thing for me to include in the beginning of the video. Basically, its telling the printer how to print the object you want to print. And generates a file you can print.

[@Voidmonster]

Okay, *now* I'm really paying attention to Pikaslice. I just tried slicing a full Jupiter build plate in Chitu Pro -- took a bit over 1 minute with volume calculation on and *2 seconds* with it off. This seems to be almost purely a GPU thing. With volume calculations on, the CPU was doing most of the work, with it off it was purely the GPU (I've got a 3080 in my desktop machine). I'd bet Pikaslice is also relying very heavily on the GPU, and doing the sorts of operations that the IPad is more optimized for on top of that.

[@UncleJessy]

Wow thats some impressive slicing time! Chitu for sure seems to be optimized better for PC than mac.

[@Voidmonster]

@@UncleJessy It's *got* to be due to GPU jiggery pokery. I only upgraded my graphics card last week, and I'm certain it didn't slice anywhere nearly that fast before.

[@JustNice980]

I'm really curious how Voxeldance Tango would fair in this race. Elegoo has a partnership with them and they are giving out lifetime licences with the Saturn 3 Ultra. Might be worth testing.

[@shinaikouka]

Out of curiosity, which slice did you use to print at the end? The drastically lower file size of the PikaSlicer made me wonder if there might be something amiss!

[@UncleJessy]

I used all of the same models across all 3 Slicers Mars 3 - Devil model + base (2 files) Saturn S - 3 little demon wing monsters + a Bust & base (5 files)

[@shinaikouka]

@@UncleJessy Apologies for not being clear. I mean which slicer’s resulting file did you print with. I’m not as familiar with why one slicer’s result would be so drastically different in regard to the file size, so I was wondering if that might’ve resulted in a better or worse print.

[@resynnminis7406]

Love this video. Would also like to see a comparison of the sliced files actual print time vs each other, and what they actually estimate. Keep up the great work Clayton!

[@socialmediatouch]

Another learning experience day from the 3D professor thank you uncle Jessy

[@chriselliswest]

I can't wait till Prusa adds supports for other SLA printers! They did that for FDM a couple years ago and the speed and quality drastically improved on my Ender!

[@chriselliswest]

By comparison, I sliced a file in PrusaSlicer and it took 10 seconds. Same file in Lychee (not including the 20 second ad time) tool 1:08

[@bitzbox]

I have an Anycubic Photon Ultra so have to use Photon Workshop to slice for that and it's lightning fast. Literally takes no more than 3-5 seconds. That said the Ultra is a DLP printer so may slice very differently to those using a screen.

[@charlesfowler3464]

The slicing times are also going to highly vary upon the processing power and memory of the computer doing it. My gaming computer sliced a fairly large bread in about 20 seconds

[@mdrnhl]

Thanks!! p.s. Archvillain's sculpts are GORGEOUS. Highly, highly recommend

[@UncleJessy]

[@spendymcspendy]

I absolutely love Lychee Pro but definetly have to look into Pikaslice. Thanks for the great content!

[@UncleJessy]

For sure! And I believe the maker of the slicer is looking at more trial options as well

[@ronisin710]

I've used Chitubox for 3 years and it never delays when slicing. I run it on an AMD Ryzen 9 7900 with 12 cores and 64GB of RAM tho.

[@TheMidnightSmith]

Man is that on a Mac with chitu? I got 45 seconds with models filling the build plate and half the volume tall.

[@UncleJessy]

Chitu + Mac = not great, Chitu + PC = Fast Lychee + Mac = Fast, Lychee + PC = Slow Well at least what I saw/was showing in this video

[@bananaking4955]

The time it took to slice your files is shocking ! Is it a Mac thing? I'm on PC and it slices in seconds with both Chitubox or Lychee, and never failed. Looks like there is an issue with your machine, not the slicers.

[@UncleJessy]

Later on in the video I show how it ran on my new PC. For sure more stable BUT Lychee was significantly slower on PC while Chitubox ran really fast.

[@TDax]

I use the free version of chitubox ....seems lightning fast on my dell laptop. I must of sliced many hundreds, of files on it, for various printers and it has never hung/ crashed/ misbehaved like in the video.

[@PolyWorkshop]

@@UncleJessy if its CTB, then it's chitu SDK speed....

[@unB10]

@@UncleJessy For sure it's faster on PC. I ran one test where I started slicing on Lychee (AFTER the 20 second ad), then opened Chitu Pro, loaded the same file, sliced the file, saved the file to a thumb drive, and closed Chitu Pro before Lychee could finish slicing. Lychee is just unusably slow. I'll never understand the love it gets. In running a large print shop, it is subpar in every aspect I've tried to use it on.

[@RoseKindred]

I am so confused about how you got these results. Not doubting it since I never used those slicers, but how are they this slow? Is it the extra features like viewable supports? I have Ultimaker-Cura (I clicked upgrade on Cura that came with the machine) with some edited files to put the Neptune 2S back on, the rest is just "standard" settings and files. My computer is running Windows 10, with 16 Ram but the rest is potato quality. That being said the longest I have sliced was about 30 seconds on a very large file, roughly 600mb. But that did not need support so I don't know if that would have changed the times.

[@UncleJessy]

Yeah, unfortunately the FDM vs Resin Slicers process completely differently and FDM slicers typically can generate your print file fairly quickly. While Resin Slicers typically need to generate an Image of each layer that needs to be printed

[@RoseKindred]

@@UncleJessy Thank you for the explanation. It is a little surprising considering both printing styles handle the same file types. I've always assumed that resin would be faster in all aspects based on the way it prints, full layers versus fused continuous lines to make 1 layer.

[@tadhgd350]

@@RoseKindred both types do not handle the same file type, resin printers use a series of high resolution images which take longer to generate than gcode that fdm printers need takes. That being said, these softwares NEED optimization to properly run on the apple chip he was using, you can see that based on how pikaslicer runs on his iPad, and with a better chip it would be even faster

[@RoseKindred]

@@tadhgd350 Thank you for the information. Resin doesn't print STL/OBJ files anymore? I've seen comparisons of the same model printed on both machines before. I know the g-code that is inserted into the machine would be different, just like how I cannot use the same code for a CNC and FDM.

just did some tests of my own and one thing i noticed slicing the same file it was a bigger file size on lychee over chitu for some reason

[@thecyberhobbit]

i'd be great if you printed the same model at the same size on all 3 slicers and the printed with the same printer.

[@UncleJessy]

Yep! Seen a few comments asking for that and will look at doing a followup on that to compare!

[@Protocol-X]

Do you still have your photon m3 max? I have 2 weird issues with mine. With lychee, it was working fine, but after upgrading to pro, all sliced files stop printing after the first layer. I've even done a clean Uninstall and reinstall. The other issue is on every print the first 25mm the print is fuzzy, almost like it was printed using out of focus layers. That issue happens on all slicers. There are no failures, shifts or anything that would indicate a z axis issue, just appearance. It's far past the transition layers, the Feb isn't getting stuck, and it happens with all types of resin. It's not bubbles as sometimes I've kept the resin overnight before printing.

[@mattperson7293]

I really don't mind about the time when we're talking just minutes. I wouldn't mind if it took 30 minutes if it meant the best resulting prints and reliability of course. I imagine one of the biggest factors in time to slice is going to be anti-aliasing?

[@UncleJessy]

Yeah, I had it enabled on all of these as I knew it would impact the times. One thing I didnt consider is AA on vs Off time compare... oof so many factors here haha

[@mattperson7293]

@@UncleJessy I know folks that export their supported files out of Lychee to generate the .ctb in Chitubox for the better AA. I've actually considered it myself, I've seen results that do seem to bear that out. But of course that's definitely a much slower process... but it's worth it when you're trying to get that perfect print. Also, in 3D rendering the AA is usually one of the bigger influences on render time, so perhaps Chitu is slower because of the better AA?

Something bothers me. I bought an ultimaker and you use it with cura free. Why with resin printers do you have to pay for the slicer? Shouldn’t it come free of charge since you’re already buying the printer? It’s like buying an inkjet printer and having to pay monthly for the drivers to work.

Haven’t finished the vid, but I’m going to guess the iPad Slicer wins. Those iPads are monstrously powerful and optimized for what they are (and if the app devs take advantage of it, it can give insane performance - just look at what some of the video editing apps can manage lol…) I doubt those “desktop” slicers are optimized for great multithreaded performance.

I don't know why my results with Lychee are so much slower. I use a super fast computer, and with Lychee slicing the same plate (11 files at 20micron, 4352 total lines) I get a total 4 minutes, 1.5 seconds on Lychee. The exact same files and settings with Chitubox Pro take 65 seconds if calculating resin and only 2.4 SECONDS if not calculating resin (I don't use Lychee often so I couldn't find out how to turn off resin calculation for that software). Part of the reason I don't use Lychee is that it's SOOOO slow. Adding stl files, arranging, adding supports, slicing, it all seems to take 10 times longer than Chitubox or Chitu Pro. Maybe it uses cloud computing instead of utilizing hardware? Either way, it's completely unusable to me. I run a print shop and regularly print files for machines as large as the Jupiter at 0.02mm and if it takes longer than 30 seconds to slice, I'm losing money.

Would love to know the differences in time for MacOS vs Windows. (AND that is what I get for commenting before the video is done. ;) )

[@UncleJessy]

Haha 🤘🤘

[@Voyajer.]

Ugh why can't resin printers have some decent open source slicers? It really turns me off of resin.

[@andreasostensson5747]

Saving a minute on a 5 hour print. I would go for reliable everyday.

[@SaschaUncia]

This is a bit like ranking different fruits from best to worst based on how sweet they are. It's just one datapoint, useful to know, but misleading when taken alone out of context.

[@UncleJessy]

Yeah, but it's a starting point for the video series on comparing the slicers. And 7mins vs 2 mins vs 30 seconds is pretty big in terms of slicing times

[@SaschaUncia]

Hmm.. Alright, that makes more sense then. I still think it could mislead newbies if viewed alone out of context, but it's still a useful metric. I've been using Lychee since beta. I found chitu slow, but it also crashed an inordinate amount and generated a lot of stray pixels in the final slice. Lychees 2D hollowing and non-destructive holes are also really useful.

[@tabathasteele7547]

Can you slice on an android tablet?

[@UncleJessy]

Not yet, I believe they are going to be looking into that in the future

[@ausfoodgarden]

What? Prusa slicer doesn't work on anything other than a Prusa printer? Are you kidding? I've been using it for over a year and I do not own a Prusa printer. I don't know if it works with your sponsor Elegoo, but it works on many other resin printers.

[@graebeard6882]

Never heard of any of these slicers. From the start I've been using Cura, with no problems. While most of my stls are fairly simple, I have not had anything longer than about 10 seconds. Works for me .

[@cameronmalchow7597]

Cura only works for FDM printers, not resin printers.

[@UncleJessy]

Yeah these are all Resin 3D Printer slicers. For sure worth looking at on the FDM slicer side as well

[@runklestiltskin_2407]

Fastest slicer is not the most important metric for me.

[@UncleJessy]

30 seconds vs 7+ mins of my time is pretty important to me... and I'm guessing others as well. What would be your most important metric? Would love to dig into that as well.

[@runklestiltskin_2407]

@@UncleJessy Hi, I can trink a coffee while the slicer is working, overall 7minutes of a 5000 layer print is relatively insignificant. To me the most important point is not having to waste a print due to bad supporting. Lychee 4 already disappointed me here, autosupports are still not supporting every island, autosupports still remove manually placed supports. Chitu free island detaction is a great catastrophe. Thanks for answering and have a great evening.

[@ygyg37]

theres a new slicer name Voxeldance Tango

[@UncleJessy]

Oh nice! Just looked it up and going to check it out!

[@screwyluie]

Your ipad slicer is faster because the storage is faster. It's that simple. Put faster storage in your laptop and save some time

[@hugo_bart]

try slicing on a big buildplate printer, then things really start to matter

[@keyplayermark]

Ok, PC vs IPAD. Different processors and OS. So... yea Mac is faster, but not paying for an IPad Gen5 tablet for the speed of a new slicer. Odd, I have never had the chitubox lockup like he described on my free version. These do run like crap on laptops due to the GPUs and slower CPUs. On my Dell Desktop with Nvidia card and 32 gb, it runs fine. On my Dell laptop, I get the same issues he has on my mars and saturns. Slow and locks up. Saturn 2 arrives tomorrow, so we will see how it does.

[@UncleJessy]

Congrats on the Saturn 2!! Have a big overnight print running on mine right now. Yeah later in the video i show it running on my new PC laptop and Chitubox is much more stable/sliced really fast. Lychee on the other hand was super slow on my PC vs being fast on my Macbook

[@sammacin4082]

Anyone here getting slanted prints on their elegoo Saturn s? My prints all come out slanted like the rails are leaning forward

[@UncleJessy]

Say what? Have you psted about it on the Saturn Facebook Group? Would be very interesting to see what that could be

[@kerricaine]

i absolutely hate that lychee doesn't support the files for my printer :/

[@UncleJessy]

Which printer is that? They seem to support the most printers

[@kerricaine]

@@UncleJessy voxlab proxima. at the time i first tried anyways, they didn't offer the proprietary file format proxima uses.

[@ChrisOsberg]

It might be worth considering whether the slicers can be used without an internet connection. It's not going to be a problem often, but there are times where it could be. I imagine that Pikaslice and Chitubox don't require an internet connection, but Lychee probably does--for the ads.

[@UncleJessy]

Very valid point. And will make a note of that when I do the individual slicer deep dives!

[@markmorgan8378]

Tell us how you really feel about Chitubox.

[@UncleJessy]

Haha it's been my primary slicer (free version) for a few years now.

[@markmorgan8378]

I really like Lychee. The supports just come off like butter.

[@Dark0Storm]

With the lychee ads you can just click the link and skip the ad. No need to actually watch it.

[@timothyboles6457]

i can't even get chitubox to download

[@ThantiK]

@8:45 if you don't want to watch a 10 minute video for a 10 second answer. And he doesn't actually cover the ones that he has logos for in the clickbait video thumbnail -- he just handwaves excuses as to why he didn't use them. When it doesn't matter if he has the printers for them or not - because we're just asking about SLICING times. So the excuse about "oh, we can't use prusaslicer because it's only usable on prusa printers"...is a shallow one. Same goes for the Vlare.

[@UncleJessy]

Huh? You literally cant use Vlare / Prusa slicer / photon workshop for anything other than their specific printers. These are literally the 5 Resin 3D printer slicers that I was aware of. And again, trying to focus on the ones that can work for multiple brands.

[@TheBlackweld]

No love for Formware...

[@UncleJessy]

ohhhhhh man. I knew I missed one. Will see if I can download & test that out with these same files!

[@drkstl]

You forgot formware3d

[@TheIcemanModdeler]

So basically stop using a Mac!

[@UncleJessy]

Haha towards the end I show my PC slicing results My Mac - Chitubox = Slow / Lychee = Fast My PC - Chitubox = Fast / Lychee = Slow
