Eliminate seams in your 3D prints with scarf joint seams - An exciting development!

@@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.

[@attack125]

@@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.

[@PhantomBlank]

@@attack125 it might look simple but that's very hard to implement reliably.

[@SaigeSauce]

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 ☺

​@@MarkusNemesis You can't print functional parts in vase mode unless they're toys.

[@DrPersonman]

​@@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).

Truly love that 3D printers more and more move towards the 3rd dimension, rather than just printing horizontal layers.

[@nikoraasu6929]

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

[@jokerace8227]

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.

[@bonovoxel7527]

Yessss dude, non planar slicing, even with a mildly steep angle such as just 20°, would be gamechanging!@@nikoraasu6929

[@bonovoxel7527]

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

[@roderik1990]

That and cooling becomes a lot more awkward if you also have to have enough clearance for the non-Planar moves.

[@dougsholly9323]

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.

[@Jynxx_13]

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.

[@amicloud_yt]

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.

[@riversshadow9678]

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.

[@joshdog1648]

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...

[@UncleJessy]

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

[@mariospanayiotou6644]

Exactly! I feel like this is the only thing keeping 3D printing from perfection.

[@MrGerhardGrobler]

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!

[@SuperInstaGib]

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

[@teapotwar]

[@AmaroqStarwind]

Not to mention "fuzzy skin" for creating textured surfaces, which can also help hide seams.

[@bonovoxel7527]

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

[@reyalPRON]

been fiddling with this for a few days now and i must say... impressive cylinder results both external and holes are 100% gone with 33/55 wallspeed @ 0.55 and .6 width on .4 nozzle. this was so good that im following up with this comment due to my gratitude to you for bringing this my attention. found this because i forgot to change the process profile from my "glass petg" which is as you understand veeeery slow. i hit the 166% and it was off to the races. there is so so so much happening in this scene than in the early days where i thought i could keep up :) cheers for yet another well delivered INTERESTING video sir. im now stuck testing this on the second roll

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.

[@802Garage]

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.

[@tarakivu8861]

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.

[@mariospanayiotou6644]

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

[@802Garage]

@@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.

[@РоманПлетнев-г3э]

It would still need to move in & out of outer layer to print infill. So even if outer layer is printed in a similar manner to vase mode, the seam still would have to be somewhere

[@802Garage]
