I'm not kidding. This treelease of UItimaker Cura is something I've been watching for a LONG time. I use tree supports more than any other support type, and this improvement is really a support game changer. Watch, and find out why.
NOTE: This is important. I prepared *A LOT* of this footage in advance, using the fork version. So screenshots may be of the alpha version or the fork version. The impact of this is largely the difference in where the settings are located on the list.
Also note, not that anyone reads this far: there seems to be some confusion over the brief mention I made about Prusaslicer's repo. They have a private DEV branch. The project is of course open source. The reason I was mentioning this, which I did explain, was because it stops me knowing what's coming in terms of tree supports, because it's private. It means I know no more than you do if you watch their live streams! That was my point. And it's entirely their choice. And it's also not that uncommon for companies to do that. There's no story here other than they didn't used to, and cura don't.

Its crazy how even large companies use these types of programs and the devs arent rich already. They really do deserve so much for making such an amazing tool for all of us
I looked at the other 3D slicers for FDM and Cura truly is best in class. Tree supports are revolutionary and enabled me to print all sorts of things on my Ender 3 Pros that I wouldn't have thought possible and only printed using my resin printer before.
Also based on random unverified Google searches Ultimaker has 300 employees and revenue of $67 million a year, so their devs are probably being compensated pretty well.
@@AlecMHansen idk other than tree supports i really dislike cura. It's just awfull to use
@Alac Hansen, we (I'm one of the Cura devs) are compensated regular wages for a software developer in the Netherlands. Which isn't exorbitant but fair compensation.
But we are also all open-source fanboys who are makers and DIYers. It is not uncommon that we decide to make contributions to Cura (or other open-source projects) just because we care for that project, and we want to add specific functionality to make our own life better.
BTW, this new tree support wasn't made by an UltiMaker employee. Thomas Rahm is a community contributor who made this in his own time. So please check if he has a "buy me a coffee " link if you can spare something or show him some love in another way.
Doesn't need to be much. It is often the thought that counts, th
Support blockers finally working as you would expect might be my favorite part of this.
Now if the add a support add on would actually, you know, SUPPORT THE FRICKIN MODEL?? that'd be great!
Wait, I've never had any issue with support blockers. Always used them. What was the issue?
@@fns58 whenever i personally used them they always would make supports even though my blocks were there

I have been using a Cura Tree Support 2 for about 2 months now which is more or less what you have there, the time saving over Cura 5.1 is enormous.
Yeah Thomas let me know about it around 9 months ago, but I am the king of procrastination 😒
You mean I can get these in cura 4.whatever?
@@billallen6109 No
@@billallen6109 I've had them in my cura 4 since I started using my 3d printer a year ago

Haha Cura beat PS to the release, very nice. I've never liked the old style tree supports but keen to give this a go!
Definitely give them a go! 😁👍
They always seem to beat them.
I'll wait for Prusaslicer. :) I just like it better overall. Bambulab's version of PS is even better imo!
John (above)mentioned ARC overhangs in combo will be a game changer i feel the same Merry Christmas Angus and to you an yours!
Merry XMAS! 🎄🎄🎄
They've grown so well and look mature now... looking through the comments, others agree.
Big thanks to Thomas for tending that garden for years!
Couldn't have released this video at a more ideal time for me. Thank you! Subscribed. Definitely appreciate the visuals as to what each settings does. I'm a visual learner so just reading the descriptions of each setting doesn't really do it for me. Looking forward to another video where you dive deeper.
Oh nice! I like tree supports in most cases since they save on print time and material, but I'm definitely excited for an improved version.
Looks great. Can't wait for Prusa Slicer 2.6 and their Organic supports.
I love tree supports since their release and I am so hyped for the better version! It was a really nice christmas gift from them!
Guy from one day in the future here! I’m born and raised on planet Prusa so this is the first I’ve heard of tree supports. They look amazing! I’m excited to hear you say they’ll be in prusa slicer eventually as well. Thanks for the video!
This is fantastic. I got into printing a couple of years ago thinking we were still in the 90s and this technology hadn't come down from thousands of dollars. $250 later and I'm printing. Because I came in when I did, I've only ever used tree supports. But this is a whole new level of control!
I know, I wish I'd got into it a couple years earlier too, somehow it went from £2k for a makerbot to £200 for an ender and I hadn't noticed
This is awesome. Thank you for covering this almost instantly. Merry Christmas🎄
This how I've always expected tree supports to work. I was severely disappointed in the old ones as I mostly wound up with objects permanently cocooned or breaking the model trying to free them.
My best results have come from putting in my own supports in CAD before slicing. My own wind up being similar to the new method. This should save me a lot of time.
We just started with 3D printing a few days ago and this comes like a christmas gift. Thanks for the video, i could have missed it otherwise.
Never had a snipped do that oh god
Yeah, no way that should happen when clipping plastic
I've been using the old tree supports over regular supports for years without any major problems. Compared to regular supports they're always faster to print, but I'm glad they got improved.
Gotta get onto these treees, very big thanks to Thomas ❤️
IceSL has had this style of supports forever and is an underappreciated and amazing slicer. It also has the most accurate slicing algorithm of any slicer I've used.
Thanks for the video however, nice to see Cura getting better supports.
Thank you! I am printing noob and didn't even know Cura did tree supports. You will save me so much filament and clean up.
Prusaslicer is under AGPL, which means once they release the binaries for the software they have to release the source, so if by "private" you mean "under internal development" that's not the same. They also can't re-licence the whole thing, without asking the original devs of Slic3r to accept a new license.
Yes I wasn't implying they are in breach of licence, of course they are welcome to do whatever they want with their in development branch. I merely said it doesn't make sense to me or help me know what's coming up.
I managed to get this video out two days later than the release because I was able to prepare a week or so in advance. Without that, it means a week plus before I can get anything done, takes a lot of work to make vids like this
Wow, this looks amazing. Can't wait to see what kind of projects I can make for my channel eventually. Thanks for this great video!
i love how tree suports can be easyer to remove -also free christmas tree with every print when used lol
Thanks for this video! This is great! I had a model I printed multiple times with tree supports with delicate piece that no matter how careful I was, removing the supports broke the piece! This was because it was way too much support, and it looked very similar to the shrooms you showed. I'm pretty sure I shared it on the Discord server.
That's actually amazing!
I can't count the amount of times i had a pretty neat print, which had supports that were literally impossible to remove without some exotic tools. "It looked doable in the Cura preview though"
A "mushroom" huh ? Suure buddy ....we all get looonelyyy sometiimes xD
I find crushing supports with needle nosed pliers first makes them come off easier
Wow! I mostly design functional prints that don't need supports but this is amazing!
Started a print with tree supports 20min ago. Oh well, I'll try this next time. Thanks for the video and have a Merry Christmas and a Happy New Year!
Haha, stop it, start it again! 😅 Thank you! :)
@@LostInTech3D Ended up doing just that. Printing a deer model with antlers, and it now seems to recommend far less support for the antlers, and a much shorter print time on the same profile I was using. Fingers crossed, if it works as intended, this could be a huge improvement!
Update: It turned out great!
As a big fan of tree supports who hated both the support blocking interplay and the incredibly difficult removal on some parts, this is amazing. I didn't even finish the video before I downloaded the alpha. Thank you.
Thank you for the info! I’m new to resin printing and I have been learning about supports
Honestly this is one of the sole reasons why I have sworn by flashforge's slicer for years. They have had these "new" treelike supports for a long time. Now I can switch to cura and actually have more control over my settings.
A big Merry Xmas to everyone from the Lost In Tech Community! 🎄🎄
This was a great video to see early on Boxing morning. What an upgrade! Cura has been the preferred slicer for my Cr10s but tree supports have been pretty terrible as you described in the video. Love the channel and thanks for sharing.
I've been working with tree supports in FlashPrint for about 10 years and I really missed it in Cura. Very happy that it finally becomes available!
I've always liked the tree supports and have been able to generally get them to a usable state with support blockers, but now, it looks solidly plug-and-play, making it a lot more user friendly!
Gonna try it out right now. Also, Merry Christmas!
Just learned that support blockers can be scaled up and down :D I've been setting these in small cubes and struggling to cover the unwanted areas fully! LOL I'll be using this setting more from now on!
I've been using UltiMaker-Cura-5.3.0-alpha+xmas for a few days now it is improved greatly. I experienced a minor "will not slice" error on a Santa model with Fuzzy Skin enabled and reported that bug. They (UltiMaker) responded immediately for a work-around (increase the model size by 5%) and are trying to identify the "root" cause (get it?). Much, much, much better than paying another $59 USD for the next (finally) release of Simplify3D (not worth the money - too little too late).
Haha I approve of the joke. The workaround is also to move the model slightly on the build plate, this bug is not new on this release believe it or not
Thanks god that there is a new way of tree support, i used it the last days and it became so strong i could not remove it at all anymore. Hopefully this new version is the one we all really hoped for
Just when prusa slicer was starting to grab my attention, cura goes and tries to one up them 🤣
It's good to see the same features in both slicers I think, they are both way ahead of any of the competition so I guess it works out!
@@LostInTech3D and then we have the new S3D release with new features that were standard in 2019 and none of the newer stuff
The same developer made the tree supports for both programs, they are the same!
@@Karavusk Simplify3D updated? I used that one for YEARS and really like the interface compared to Cura but they never added features! I finally made the break when I heavily modified my printer and it made sense. Still learning Cura but Simplify has fallen so far behind it’s not funny. A real shame too since it’s a commercial product and not terribly cheap either geez
@@BLKMGK4 Then I have "great" news for you. It is still 3 years behind and you would have to rebuy it since it is a paid update.
By the way Prusaslicer might be slightly more familiar for you but both are great options.
Adjusting flow on the old style of supports is how I got away from that problem you were describing early on.
Amazing. I do a lot of very organic shape printing that needs lots of support and this will be a BIG game changer
As a resin printer, glad fdm printers have been able to get these as well.
Omg thanks for showing that I can resize support blockers. Should've been obvious but I din't realize that and was putting down a ton of them all squished together.
it's really not that obvious tbh!
Cool, you convinced me at least to take an extra step before each slice to see which support type would be better per each print.
Love this. Nothing better than a program behaving how you intuitively think it should.
Great video thanks, and merry Christmas to all.
thank you, you too
Good find, thank you for sharing. I'd played with the tree settings and support blockery stuff in Cura before and got the trees to some resemblance of sanity playing with the settings but this alpha seems to have some useful extras, I might just grab a copy. Thanks again!
PS: My biggest lesson that I learned-ed-ed a few months ago has been: 0.6mm nozzle, 1mm extrusion width, 2 walls, and 0.28mm layer heights. Way stronger. I tend to design working mechanical / workshop things with measurement multiples of 2mm anyway, and that means some stuff just prints up to twice as fast (and the rest around 30% faster) than defualt 0.6 draft mode. And stronger, did I mention stronger? A lot stronger?
I've honestly been surprised, it felt like having the cake, AND the cake not being a lie, AND then getting to eat it as well... Now looking for another old Ender3 Pro to set up as a "fiddly bits" (and comparison testing) printer using smaller nozzles, but Brucely ain't going back. (Unless I really need some finer detail before I turn up another machine.)
I ended up rotating that frog until it didn't need any supports in its mouth when I printed it last year, tree supports like that look like a much more convenient way of printing it. I'm looking forward to the orange slicer version of this
Urgh just printed a 3 day print that would have gone soooo much better with these new tree supports!!
Thanks so much for highlighting
As a fairly new printer I’ve stayed away from tree supports just because I make a big mess and haven’t dialed my settings in. But this gives me hope to give them another shot so thanks for sharing!
Honestly, the one thing id love to see is the Lychee style "support islands/floating starts only" option (and project compatibility cross slicers).
Good information, as I am going to get a 3-d printer soon and doing research at the moment
Hey nice Christmas pressie!
Thanks for sharing this feature!
Phenomenal! This is going to save me so much print time and material, the new tree supports that is.
This adds some much needed fine tuning!
The proprietary slicer for the Flash Forge printers has the best tree supports I’ve ever used. Seems like Cura is finally catching up!
Cura is FREE and works on most printers right out of the box. I'm a novice and "old" and thus appreciate Cura more than most without having to fine tuning too many settings.
@@hendrikjbboss9973 their slicer is also free. Sometimes it’s easier to use their slicer to cut and section parts than Cura. Branch out from Cura, lots of cool stuff and lots of learning.
Looks good and new content in Xmas day for us nerds lol. Thank you lol.
ive used the 'old' tree infill before for a small trex skull, it just peals away (tearing the material at the layers) if you *turn off* infill for the support structure
Bambu Studio's tree supports seems to resemble the new style already. Either way, catch up Prusaslicer!
This is awesome. I always used tree supports for 3D prints of game characters with lots of msall and fragile details, normal supports were way too hard to remove. I had to spend like 30 minutes removing the capsule of a tree that formed around the entire character. Had to break it down bits by bits. I bet that with these new supports the entire process will be easier.
9:15 such a perfect application for what i NEED
I wish I saw this 4 hours ago, it would’ve saved me a lot of time lol, guess I’ll have to finish my current print
finally.. i hope they keep working at this.. many of my prints ruined trying to remove supports which fused..
Conical supports setting also allows overreach, which I used in many cases where tree supports didn't work too well. Might not need to do that anymore 🙂
(although standard supports produce superior quality on any supported flat surfaces layed on top of them when used with support roof, so for these cases I might still prefer setting them conical instead of tree).
I'm from 13 hours in the future. Holy shit the world is crazy now!
And yeah, thanks for the breakdown. The feature looks very polished now. I won't try it just yet, but the next time I need to print a support-heavy model, I'll remember this.
Finally. I had so many issues with way too much tree support.
Straight up popped myself in the eye with the broken off pointy part of my Ender 3 filament cutters with the blue handles... while I was using it to cut off supports... luckily no serious or lasting damage. At least not to my eye.
Tree supports combined with arc overhangs would be very useful.
Great content here. Thanks.
Early in my printing life I gave up on tree supports because they I thought they would be a good idea but instead completely ruined and buried a multi day print that I wished for before I even bought a printer. But this, this may be a seed of hope being planted. Nothing concrete but maybe.
Those mushrooms look filthy with those old style supports...
Tree supports are cool. It will be nice to see them in Prusaslicer since I generally prefer that slicer because it starts faster and slices faster - probably a result of not using python for so much stuff.
Hehe the frontend is python, the back end is mostly c++ as far as I'm aware. I think the slow slicing may happen in prusa too when trees exist, as it seems to be the cause of the slowness in cura, but we will see
My first ever 3D print, I printed a few, tiny goblin archers (2cm tall) which held their little bows with their tiny strings sideways and aimed forward (so floating). I assumed that removing the supports from those bows would be nightmare, but somehow, with the new tree supports, I pulled on the supports and they just, detached? like magic. and the thin ass bow was not damaged AT ALL. I was amazed.
thats quite good going, I've been meaning to do a vid on printing models/small stuff for a while but it is _such a pain_ to get supports to work.
if they add custom drawn supports it would solve all those issues. And would be really great to have more control over supports for FDM saving material and print time.
I still have a couple of print with unremovable supports done in some test-prints.
Dude... why is no one talking about this new version?? This is the first time in my life that I have joy removing the supports from my PETG prints, it's so damn easy to remove them right now.
Good question. I don't know! People are strange.
"Mushroom" 😛
😂 I'm not a fungus-ologist if that's what you mean
He's a "fungi" for sure... Ha
@@LostInTech3D I think they were going in another direction…
Mushroom!
Oh yes I'm well aware
I love this!
So this is where Prusa's upcoming "organic" supports come from!
I can see some people trying to use these new tree supports to create model trees. Design a sacrificial object that creates a template for trees and the keep the support.
The 85 degree supports at 4:33 makes me think that arc overhangs might be better suited to tree supports than the actual print.
"Tree leaves.stl" and print it in the air, bingo! You can even simulate Fall.
Prusaslicer is actually the most dbag slicer. They seriously have a closed source codebase while they lift code from Cura’s open source code? That’s crazy. Which wouldn’t be so bad if they didn’t try to sell it as their own. As a developer, I’ve only seen the weakest dev teams pull that garbage.
@@NicodemusT how is PrusaSlicer closed source?
It's not closed source.
@@LostInTech3D you literally said their codebase was private in the video though…
Oh this would have been perfect a month ago, was trying to print a model for a friend and the tree supports kept genorting in the air, and limiting the design choices I could make. (ended up modifying the model to print with just 2 manually placed supports)
Yeah, I found out the hard way about those clippers. Thought they were great up until the point where it became a dangerous projectile.
I can't wait for the new PS alpha. My current model which failed due to bad "experimental" MMU settings could massively benefit. I really struggled with traditional supports in some areas. It would certainly benefit. So I'm not going to reprint it until then. In the meantime I need to fix these settings so it doesn't fail next time. The color switching was failing in the extruder rather than the loading boden tube making it think it had filament when in fact it didn't.
I had one of those cutters snap on me and yes the end hit me in the eye! Fortunately it missed my actual eye and just hit my lower eyelid but dayum it hurt and that was close to me losing an eye!
Lucky!!! But yeah thanks for sharing, people never believe me
I really should try this
Now I can print the "impossible" dragon! 😂😂😂
Talking about those snips, please be careful with them. I had a pair break while doing something I wasnt supposed to do. My thumb was near the tips and the broken tip shot through the end of my thumb.
I got your point of usefulness with the rectangular component example early in the video where the supports don't touch the bottom of the part, so this may be pedantic, but of course you would (almost) never print that part in the orientation shown. Flip it 45 degrees and it would require no support at all. As an aside, those must have been the cheapest pair of wire snips on the planet! Just about any pair of snips that didn't come free with a 3D printer will have zero issue with cutting anything you can print from here to eternity. You are certainly right that they're not the optimal tool for working directly with the support/part mating surface, but they're a good tool for other support snipping scenarios.
I hope that didn't come off overly negative, but it tends to be in the details in manufacturing and fabrication that can take our potential from good to great, so just details such as consistent mention of orientation discipline may be helpful for those early in their journey. You're making good content and I look forward to seeing everything grow. Best to you and yours in the coming year.
The tree supports have saved me SOOOOO much filament
I always had to do custom supports because tree and normal would incase my minis and they were too small to survive the excavation.
Big fan of the Christmas tree supports. I have been using 5.3 alpha for awhile. Hoping 5.5 still uses these supports.
yep they have been in main cura for a few months now, you are safe to update!
@@LostInTech3D cool, thanks!
OMG, Why my older version Cura tree supports looks like the "new" one!
I was flaming so hard Cura when I downloaded 5++ version. because the tree supports didn't look like tree anymore....
Turns out that by some reason before I was using the Thomas version. This video helps me a lot to find my good old (new) tree support!!!
I really missed the tree support that looks like tree! I remember now that I had problems reaching Ultimakers website at my old work and I had only access to github so I downloaded the Thomas version. Love you guys :)
I didn't know I have the option of resizing the blockers, thanks. Maybe the next iteration will have a round column blocker available?
Round ones? 😁 Whatever next, people will want spheres and polygons! Hehehe
Freaking darn good video and feature... Just int time to make my complex T-800 figurine I am doing right now. Before the tree supports were kind of Ok, but this new ones are just amazing, cleaner and cleaner
Edit, right now I am submiting a bug report, where I noticed that the Slice process is taking longer to produce the Gcode, but also there are some parameters that even after 1 hour it doesn't produce a Gcode. Specifically using a 0.4 nozzle and reducing the Tree Tip Diameter to 0.4 from the 0.8 default Value
Slice down the middle, print in 2 pieces and glue together.... rarely need supports. It's already a 3D print with lines so what is one more line going to hurt?? LOL. Love your vids....
Freaking cool!!
I have a sitting dog stl file. On top of the branch would be his hanging ear. Unfortunately the tip of the branch is so fine it does not hold the entire ear until it reaches the head. How can I add MORE Branches? If I add diameter to the branch unfortunately it still comes to a point. I would like to drag the tip to a flatter piece almost looking like a paintbrush? Thanks
I have to wonder if the new Bambu Studio "slim tree" option is based on this, and if so to what degree. I think somewhere in the notes for the newest beta of their slicer they mentioned-
"we learned the initial idea and code of tree support came from Cura a few months ago and we are grateful for that"
They said a few months ago, which is before the release of the Cura beta of course, but they could very well be developing off the same source
as far as I saw in their code base, they based it from our (Cura) old tree support
I have a Chromebook and would like to get Cura slicer to work on it could you pleas explain how to install from start to finish how to get working. I can’t seam to get files to export for me but I’m sure a full tutorial video on Chromebook Cure would help a lot more people out.
3:00 looks cool
If you get higher quality flush cutters they won't snap. I have a set of Crescent hand tools and they work very well even on rough projects.
