Soon, the visible seam on 3D printed parts will be greatly diminished, thanks to a new development called scarf seams. In this video, I shine a spotlight on the work of the developers, as well as the work of the community in testing to make sure it works. All the details you need to test yourself are included, plus my own testing results across a range of 3D printers.

gotta love the tenacity of the FDM world, still improving while remaining open source
Sharing common goals!
@@ThisisDD such a relief. nowadays with most companies locking stuff up for better margins, open source is a bit of a beacon of hope. Cheers mate, I hope all of this innovation helps your future endeavors out.
Eh seems like bambu is trying pretty hard to change that, and fairly successfully given how well they are doing.
@@Alfaghettyyup bambu keep claiming they're innovating but they're not. They built on top of open source work and yet people are treating them with cult like adoration like Apple customers do.
@@Fennecbuttexactly why (and only why) I will never purchase one of their machines.
I will gladly fork over twice as much to prusa, so long as they remain open source, in good spirit. (Not if they start trying to be "technically" open source)
Oh my gosh this is going to be a game changer! Hiding or make the seam less visible has been such a time sink and annoyance. Especially with larger layer heights or silk filaments. I'm so excited!! Thank you to all the amazing people in the printing dev community ☺
Where were you the day where Vase mode died?
@@MarkusNemesis You can't print functional parts in vase mode unless they're toys.
@@alejandroperez5368 you sort of can but it's uhhh... different. You slow the speed waaay down but set your line width to 2mm+ and a layer height of .6+ (yes it works with a .4mm nozzle, somehow). If you get the speed and heat right you can make strong and functional containers or rigid tubing and whatnot.
@@DrPersonman right, two or three use cases. Not relevant to make a post about.
@@alejandroperez5368"Laughs in functional molds for wax candles being able to be printed in vase mode"
And again I'm baffled how a "simple" change can make so much difference. Kudos to everyone working on this!
It seems pretty obvious like ketchup bottles sitting on their tops.
you should be baffeled by the fact that it's 2024 before someone finally made this a thing
@@attack125 No one stopped you from implementing this 5 years ago. 😜
@@MirageDU
the fuck you talking about.
it's still not propperly done today. even in orca slicer.
cnc is almost 70 years old.
3d printing is almost 40 years old.
if you think we aren't moving too slow then you have braindamage.
i was not at all praising this advancement. i was pointing out that FINALLY it's not looking like the dark ages anymore. that we are STARTING to move in the right direction.
github. and random software passed around between friends. doesn't count.
so 5 years ago this wasn't "implementable" as you suggested.
i'm not going to do their r&d for them for something that should have been a thing since before i got into 3d printing.
Truly love that 3D printers more and more move towards the 3rd dimension, rather than just printing horizontal layers.
when we finally get a commercially sold 3D printer (or a great open source project like the Vorons - that will push companies to copy the design, which is great) that are specifically designed for non planar 3D printing then I'd say we'll start moving towards non planar 3D printing as it truly is amazing
A lot of what makes it tricky to print more freely in 3D is the shape of the tip of the nozzle itself. Maybe nozzles that look more like the shape of a tip of a ball point pen, minus the ball, would have an easier time with "beyond layering" type printing. But in some ways the tip having some flatness around the hole does seem to actually help with layer printing quality, especially when extruding wider than the nozzle's hole diameter.
Yessss dude, non planar slicing, even with a mildly steep angle such as just 20°, would be gamechanging!@@nikoraasu6929
Yesh, unfortunately. I have the 0.4 mm nozzle but often use a 0.6mm or wider line, to save time. If there will be nozzles specific for non-planar, they would probably admit no more than 150% layer width compared with the hole. And it would probably screw up the appearance a bit if the .4 nozzle has a .6 flat surface it would probably print right until only 0.58 width.
For reference a 0.4 nozzle now begins to screw up quality even at low flow and speed, around 250% width. 0,96 mm line with 0.4 nozzle still prints fine.
This won't be possible with thinner pointed nozzles.@@jokerace8227
That and cooling becomes a lot more awkward if you also have to have enough clearance for the non-Planar moves.
I've had trouble with parts that have to fit together with tight tolerances, and the seam was a big part of this. I hope this takes off and developed more.
Exactly why I am so excited for this development as well! I have two files next to my printer solely for filing down seams on tight fitting parts.
My solution to this issue for my prints was using the random seam option. It adds a bit of friction, and works reasonably well for a nice friction fit between parts. These scarf seams might help resolve the same issue but hopefully with more reliability and better aesthetics.
The reason I scrolled down the comments. I usually add geometry to my CAD parts so that I don't have to file seams (e.g small radius or v-notch on cylindrical parts combined with seam on sharpest corner). This is also quite time consuming though...
Oh wow. This could be huge. Seam lines are one thing I’ve had to explain over and over again to people who have bought 3D prints but unfamiliar with 3d printing limitations
Exactly! I feel like this is the only thing keeping 3D printing from perfection.
Preaching to the choir. No, the model is broken.
Where?
Inspects model. All is fine.
Look here, see it is broken.
Huh? Oh!
That is a seam line.
No it is broken.
It is a seam line. Like when you sow 2 pieces of cloth together.
But it is supposed to look like it was injection moulded.
This is a print. Not an injection moulded model.
Yada yada yada yada yada yada yada yada yada yada yada yada yada yada yada yada yada!
My favorite part about this is the organic collaboration that occurs with open source. This isn't just in 3D printing, but really any open source code project. I love it when the reward for participating in a solution is not motivated by reward, but rather by recognition of your contribution.
I love that this channel takes the time to highlight the community contributors making these things possible. To be frank I just don’t have the time and energy to keep up with another community, and this channel makes it a lot easier.
Hats off to the developers here, this is an elegant improvement to a consistent FDM issue that no one else seems to pay attention to. I look forward to seeing how this develops going forward
Since I began 3D printing I've wondered why there wasn't an option to basically treat outer seams like they're part of a vase mode print. Don't stop moving, just ramp up to the next layer. Obviously for prints that are sent to print the outer wall last, it would need to step inward quite quickly after that and then move on to the next command, but it should still hid the seam well. This basically accomplishes that in a clever more order based way. Really excited to try this out soon! Great job to all involved.
There is also still no detection for printing in mid-air when e.g. printing outside to inside for better dimensional accuracy. Really cought me fof-guard.
Or hole-shrinkage-compensation. SuperSlicer has it and its great, PrusaSlicer again very conservative with settings and doesnt have it.
I’ve been wondering the same thing. Also it seems (pun intended) like a lot of times the seam could be on the inside(say you are printing a helmet, the seam would be inside where nobody cares how it looks like) or even inside the infil. I guess now you can draw the seam so maybe you can do that i just didnt try it that way. I do the “layer inspection” thingy like in the video where it shows you how the layer is “drawn” and i think to myself damn the start and end point could easily be in the infill here. If i print something like a cube the layer is made without stops and z hops like in vase mode kinda, so why couldn’t the start and end point be on the inside wall or the infill? Why the outer wall? Am i missing something here
@@mariospanayiotou6644 Yeah, there are definitely a lot of tactics to hide seams I'm surprised haven't been explored. Like basically treating horizontal layer walls like vase mode instead of starting and stopping every wall line.
I can't wait to try this with random seam position for printing figures!
This might work really well with random seems!
@@tcount-si8wh That's a bummer to hear. Still going to try out of curiosity though 😆
@@brettzolstick989 can’t wait to see how companies can refine this with their bigger teams.
Not to mention "fuzzy skin" for creating textured surfaces, which can also help hide seams.
I thought the same. This is made to hide continuous seam, using it on random seams point... I figure it turning out as a broken fuzzy skin effect. Many figures in the video show something similar even it's probably not the way those have created.
But yeah, when you have a figure which is 360° saying it's meant to be seen from all angles... And the seam won't hide good in the plies of it surface bc it hasn't or they're on plain sight, this thing can improve the final result and make it at least less of a compromise on the side or on the plies where you decide to put the seams.
@@tcount-si8wh
Thank you for all the effort you put into keeping up with all these developments. It is truly amazing how the 3D printing world keeps improving and improving. Thank you again.
Love your integration with and call out of the community.
I'd love to see this come to Cura, for sure.
Coasting in the experimental tab I've been using it for a while now an it seems to work pretty well
@@t0neturb080oh, it's in Cura already?? I will have to check that out then.
@@kane101985 it isn't, not the same thing
People still use cura?
@@HE-162 yeah lol
Amazing stuff. Very cool to see the progression day after day. Thank you for continuing to bring great content!
Tried to develop something similar for concrete printing with a kuka arm. Im glad someone figured it out!
This is a fantastic development. My thanks to all who are actively work on this. Thank you for your channel and bringing this news to us. Kudos.
The contributors to the open source slicer effort are impressive. Huge respect to them.
Great development! A huge thank you to everyone who's working on it and testing it 🙌
I'm excited to see this make its way into the stable releases. Thanks for sharing!
Lovely improvement! Really impressed with these people doing the open source work
Definitely looking forward to using this in the future and wishing you all the best in the testing process 👍
I printed one of those print in place collapsible katanas last night, and wanted to have a video on while I unstuck the seams from each of the blades.
OF COURSE this is the video that pops up on my home page! I'm definitely going to take this for a test drive.
I reprinted the test one for the sword more than 50 times with no luck.
It's been pretty cool to see all these neat features get developed and become common everywhere in a very quick timespan. Love how a lot of doesn't require any new hardware either. Thanks for showcasing this!
Thanks Michael! Looking forward to this coming to the production versions of our slicers. Really appreciate the time and effort you have invested in this and the many other projects to which you are contributing.
I remember seeing those posts discussing this and I've been not-so-patiently waiting for the implementation. Very exciting!
Great team work in open source project!!
The true innovation in 3D printing these days to me seems to be all the clever ideas that get implemented in the software. It's always amazing to see these incremental open source improvements that keep improving prints.
Great video explaining this very clearly! And thanks for all of your work exposing and attracting people's interests in this and making that wonderful testing model 😽
Really appreciate all the hard work creating a fix for the unsightly seams.
This will definitely be my next area of testing. Great video!
Love this guys videos, straight to the point and inspiration always comes from them. Details without the bloat
Admiration for the community. I am just a user. So I really appreciate their efforts to make our experience so much better. Reducing post processing of the models.
This is amazing. I love that the 3d printing technology is going forwards
I always value your videos, most importantly I value your integrity - giving credit and being totally truly honest. Keep it up! Really appreciate you. Thank you for always bringing valuable
And practical content
Very excited! Thanks for printing on CR-10 max! Great work everyone!
Exactly what I needed. I was already thinking about my own improvements. This one is better than what I had on my mind, so I can forget about that.
Kudos for being so much fair with credits (y)
Great implementation, I'll try this afternoon!
Thank you for testing this!
Very cool topic. Thanks for covering in!
Amazing work guys!! Keep it up!
This is a really cool development. Thanks for sharing.
Impressive. Thanks for sharing this!
Pretty interesting indeed! Thanks, Michael! 😊
Stay safe there with your family! 🖖😊
I have been thinking of this a while now. Glad to see it being implemented
This is a great idea.
It all clicked in my head as soon as I saw the title.
I had always wondered if there was something that could be done with the seams. So happy to see this development!
This is fantastic! The second I saw the title it made perfect sense. I use scarf seems all the time when blacksmithing but it never dawned on me to apply it to 3D printing.
Very excited about these seam improvements! This has been the biggest headache in FDM 3D printing for me. Thanks everyone working on this issue.
Hello,
Thank you very much for your precise explanations of this feature and your involvement in this project to raise the profile of these behind-the-scenes developers. 😉😊
'Yippie ki-yay' to them and to the community.
👍
well done! everything is precisely described and works great, thx!
Very cool! I look forward to this technique and that new suportless overhang technique becoming standard features.
That good work, it’s how open source should work. Looking forward to have it in the future slicers.
Appreciate your videos that highlight promising new software/techniques like this. Just like non planar printing, supportless printing, and HueForge.
Thanks for sharing
exciting stuff
Really exciting idea! Great job by Michael here not only testing and informing us of this development, but also collaborating in its progress! Now we need also a video from CNC Kitchen to show us if it also improves its strength which I suspect it does
Realy nice, thx for the information and testings.
Very cool! Can't wait for it to reach the common masses 🎉😊
Dude... Your videos are freaking amazing 🤩 you are a wealth of knowledge... Keep up the great work! Aussie Aussie Aussie!
Very cool. I will have to give this orca slicer a try.
Just subscribed & recently discovered your website. My new printer CR-M4 has a very small FB community & needs all your websites testing & calibration help. Thank you so much for what you do.
What an absolutely brilliant community.
Lovely shouting out the devs
This is also good from a tolerance perspective. It's frustrating when you print something to fit into something else and it can't, 'cause seams!
awesone news, very excited and can't wait for it to be available in slicers :)
This community is just the best!
Finally! For a seamless world!
Absolutely amazing. I never thought we'd be able to get rid of seams.
It reminds me of the coasting features available in slicers like Cura. Coasting required a lot of manual tweaking almost per material per part, and the results weren't as good.
That seems to make a world of difference. If/when they make it to the stable releases, I'll definitely be using them.
Very excited for this to get good! It would greatly improve my products!
been using the 2.0 build of orca with this for a few weeks i'm loving it it's wild how things are still coming out so frequently for improvements gonna have to grab the new version tho !~
wow, looks great and its going to get better im so impressed. i'd love to see how this looks with transparent filament and the "print glass" settings
Thanks for sharing. Hopefully it will be added to the main stream.
Not the first time I see woodworking techniques being great for FDM. One of the best and fastest ways to clean the layer lines of models is with luthier wood scrapers
I use it in Orca V2.0.0 Beta. Amazing result especially with larger nozzle.
Thanks a lot for sharing 🎉❤
Really awesome. I remember a time where I cared more experimenting with all sorts of settings and even manual gcode changes to get a somewhat similar result.
Im far too lazy now but I absolutely am anticipating opening up a new version of Bambu Studio and magically having the seams disappear.
Looks like some great progress and an exciting update to fdm printing.
I've been printing my fidgets with this for about a week now, and they're coming out so much better, the seam is nearly invisible with my model and filament. Excited to see this nailed down.
Any way to make our prints better looking is welcome. Thank You
In a way I've been applying something similar for the past 6 years by using a minus value for additional extrude after a retract and at the end of a perimiter loop a wipe followed by a retract. Nice video with some great tips/suggestions, thanks!
Thanks for update
This will be an interesting project to follow. I think I'll wait awhile until it is more mature
Super cool. I can hardly wait for it to become a polished feature.
I am super excited!
This has been an enormous headache for ages, so I’m very excited to see where this goes!
YES!🎉 I had a similar idea. My thought being like using spray paint. You don't spray and then move, you move and then spray. Right now 3d printing is extruder then move. But this is move and print. Absolutely awesome!!! Ive been using Cura for a long time but this might just convince me to change. Was going to go to Prusa but I need this option in my life.
Wdym by 3d printers extruder then move? They do both at the same time
@@polycrystallinecandy it should already be in motion for a certain distance before extrusion starts. Ideally should ramp up extrusion over a few mm and then have some overlap at the end while ramping down was my thought. Very similar to what this scarf joint seems to be
I'm definitely excited for this! I'm gonna wait a bit until people hash out the best way to implement it though.
Like everyone else here I think the 3D printing community is amazing!! Thank you all for looking into making 3d printers better every day!!
I though that was already tried in a way but I guess the biggest difference is in how the layer starts and moves diagonally. I recon this makes the biggest difference since all kinds of flow setting at the end of a layer were tried already with various results. This is pretty exciting.
This is the feature that convinces me to try Orca slicer. I was going to eventually but the time is... probably this weekend.
This looks great!
man i have so many trackers on me for this to be suggested but this time it worked out well hah. was having issues with bambu slicer and recently swapped to orca, now im even more jazzed to be using it
Very very promising. I print a lot of circular objects so if this development continues I’d be very happy
The beauty of this is, that its all solved in the Gcode. So any printer (new or old) would be able to make this work.. :) Very nice
Thats why i like open source. Orca slicer have awesome community!
this "seams" amazing and your video transitions are seamless. All puns aside - nice to see this community still working seemingly seamless.
Life is not what it seams. Wear a scarf at all times.
Bravo! 👍 Many thanks.
this is so exciting!
Brother I appreciate the dedication with the scarf haha. My go to FDM TH-camr
omg
