I could be wrong, but to me it clearly looks like the Orca Slicer version is better because the Seam goes at an angle. The Studio version still goes straight up and down... Thanks for taking the time to do all this testing 🤘🤘
Just printed a test piece in the Bambu Studio Beta with a painted slant seam and it doesn't look as good as Orca. It's still a more obvious start to the seam. ua-cam.com/users/postUgkx45WqwanIllXCBjGarZbfs_BGrNKCwYaC
Orca is better overall, until they mess up a version, everything gets screwy, and you have to revert. One version raised my z offset and I had Wei readjust after a couple of unattended failed prints
@3DPrintStuff Regarding scarf artifacts; I think it might be related to z-axis acceleration settings as print head might slow down to cope with z-axis. So trying to print slower and/or more steps might improve it. And as suggested a slope crurve instead of a straight line would mitigate some z-axis limitations. Also wondering if bambu can do input shaping on z-axis?!
I just printed off a few buttons that are .42" in diameter put the seems diagonally and had the outside travel speed set to 50mm/s with the scarf and they came out nearly invisible. In Bambu

When seam painting, if you just paint a tiny bit at the top of that corner, it will automatically go vertical from there. You don’t have to try to paint a straight line down that corner
@@3DPrintStuff I don't know if this is purely an Orca Slicer thing or if Bambu Studio has it too, but as of 2024-09-24, Orca Slicer 2.2.0-beta has a "Vertical" checkbox when seam painting, which works sort of like holding shift in MS paint when drawing with the line tool; it forces the line to be flawlessly vertical, even if you fling your mouse around in circles all over the place.
Random is situational. I like it in some cases. 1. For strength, to avoid explicit weaknesses in a loaded part. 2. To distribute deformation introduced by the starts, you could get a bulge in threads for example that you can feel when screwing if its all in one spot. 3. For surfaces with Fuzzy Skin texture, which is perfectly augmented.
I like the randomized one, especially if it's something round that will otherwise have one ugly seam somewhere. With most filaments the little dot doesn't even look so bad.

I'm thinking in the next 6 months, seams should be practically invisible as scarf seams get put through the paces. Very excited. So far, had good and bad with scarf seams, but the potential is game-changing.
It prioritizes “concave non-overhang vertex > convex non-overhang vertex “ and if those don’t exist it will choose the closest to the end of the previous print path. wiki.bambulab.com/en/software/bambu-studio/Seam
When generating the ramp of a scarf seam for a none linear Z surface, the X and Y offset of the next over layer needs to be linearly (or other methods - cubic, etc) interpolated by the transition of the Z height. This way it will hopefully give a smoother result over a surface with Z axis curvature.
*Our trade mark is to have our logo running down the length of the part and we put the seam in the logo. On same of are high-run parts we took the time to make a LOGO-shaped-seem so the seem is what spells out the company name.*
I remember year ago cura used to have a setting where the printer would keep going and flow some filament as it came off of an end seam. I don't remember what seeing it was
Note: You can have both Bambu versions at the same time. Download the official release as .exe (which then will be downloaded into your windows directory) And then install 1.9.0 (or else) as .zip on to your desktop. (Installs all necessary files in one folder) You can then easily switch between them.
I'm surprised that the technology isn't to a point where the Z-axis doesn't change as it gets to the seam area to just make a continuous stream of filament.
This is a super helpful breakdown of the seam issue with varied approaches to solving it. Well done and great to put a face to the voice of your videos.
Glad you found it helpful. Wasn’t sure if I was ever going to show my face and maybe just leave it as a faceless channel forever but I think that’s kinda limiting as far as some of the video ideas I have for the future.
Great video - thanks for the effort. I really liked the example that you printed to showcase how the settings look in real life. Especially the outlook to the 1.9 beta version with Scarf seam looked promising - looking forward to have that in the finale release.
@@RED89P13 Fuzzy skin has a drop down for the options available. wiki.bambulab.com/en/software/bambu-studio/parameter/fuzzy-skin You can also apply modifier objects to exclude your holes from being fuzzy and you can see the result in the preview window. Hope that helps.
In Bambu Studio scarf seams have a starting %, setting try reducing it. I picked random + scarf seams and reduced the scarf start % and I also reduced the scarf length to 3 mm. I cannot see seams on a smoothly curved ABS GF. YMMV. Having a contaminant like GF in the material probably helps as it roughens the surface slightly hiding layers and seams.
Just stumbled upon that as well. About to start testing. Its worded as "start height" which doesn't make sense. Default was 50% and you can see in the flow that it just abruptly reduces flow. Lower percentage seems to be a more gradual flow reduction. I'm curious if delaying that reduction would result in having excess material at end of scarf and would need to lengthen scarf to accommodate.
@@generation-x406 Yes, in Orca Slicer the default is much less than 50%, I forget the number but it's much lower. In Bambu Studio I was using ~20%. I don't think of this as purely flow rate so much as the starting wedge beginning height, although I don't know if the z axis is adjusted with the flow increasing but I assume so. I imagine it as a rising wedge on the start of the loop with corresponding flow adjustment and the reciprocal wedge on the close accomplished by keeping the head level and the flow reduced. However setting it to 0% I assume invites problems of precision and contact with the previous layer. The 10mm wedge length seemed a bit excessive since all it's trying to do is feather the loop beginning and endpoints.
@@generation-x406 Yes, I assume it is the discrete divisions of both flow rate and z height injected into the g-code by the slicer, although there will probably be numerical and mechanical precision limits involved.
Just the info I was looking for to help hide seams on a replacement cupholder for my car! The although functional first print has some horrific looking seams, lol. I'm going to play with scarf seams and random location and possibly fuzzy skin effects. Just an idea for straight seam painting, could you use mouse keys to get a nice straight vertical/horizontal/45 diagonal line in Bambu Studio. I used to use mouse keys loads in Microsoft paint as a kid! Mouse Keys uses you num pad to move the cursor, I've just checked it's still there in accessibility options in Windows 11 :-)
I wonder what it would look like if you had the seam on the inner walls? For example, if you had three walls, you could put the seam in the middle of the two walls
Min 12.08 - you see these artifacts when you look on speed or throughput in the slicer. These comes from speed change at the slicer. Reduce speed to 100 and they will disappear.
i wish i had an option to put it on the inside or at least print outside/in instead of inside/out. i know they have this option in cure but not in bambu. personally i've been printing for so long and moving from cura to bambu, the setting are rudimentary to user custom settings. i'll have to try out this scarf out it looks promising thanks.
Yeah I was surprised to see a difference honestly. I'm printing another test with a painted slanted seam in the bambu studio beta to see if that was the only difference. But if you don't want to have to do this each time then orca is the answer.
Seeing this makes me wonder if development of slicers has gone backwards... I was very active with 3d printing back when they first appeared and experimented a lot build my own printer and stuff. Then didn't use my printer at all for a few years and just recently started with printing again with a Bambu Labs. But back maybe 4 years seams were fixed already! Why do they appear again in current slicers/printers? Thing is that with layer change and retract at the start of a layer it happens that there is either not enough or too much material in the nozzle. Hard to tell usually cause different materials have different flow. So you could fine tune for every spool you have but usually the easiest way is to hide that inside a wall or even inside infill. So layer change should be on an inner wall loop or over infill and then have a little coast to get the correct flow. Then can switch over to outer walls and they become perfect. Has this knowledge been lost? Or did they use some outdated code to build their slicer on?
Why can't a 3d printer go in a helix line while printing round objects like in cnc machining? i dont understand why it needs to start and end at the same point for all layers just print round and whenever you cross the start line go up by the desired layer height why is that so hard to implement...
Would you like to compare your results with the results you would get out of Cura? I‘m personally slicing with cura and i can not remember that i had such big seams on my prints in the last years. You are not the first youtuber that showed such big seams out of Bambulab. I wonder if this is not such a big thing in Cura or have i simply overlooked big seams in my prints 😅
It depends a lot upon the filament you're using. For example, it shows up heavily on silk. Seams are probably the same on all slicers, at least up until this new development.

Definitely but this video is focusing on perfect cylinders and how to slice them. At the beginning of the video I show a couple of examples of hiding seams when there is the geometry for it.
Its hard to tell from just the video, but it almost looks like on the default seams the 100% gap is actually smoother. The 0% seems like its overextruding along the sides next to the seam, where on 100% the gap is still welded but the edges have more space to go and it doesn't balloon out as much. Is this visible to you or anyone else here, or am I just seeing it wrong?
I have deleted all versions of bambu studio and downloaded the version you are giving us on the links. And for some reasone thenscarf option is not there. I am very puzzled on how this super expensive printer has a seam and all my other printers did not have any.
