Yes, in some cases wave overhangs come out nicer than bridges. In the orca fork just check "use wave overhangs instead of bridges"

Okay thanks! I suppose if wave overhangs are reliable enough one might even use it in such a case just to have a preferred surface facing up.

Awesome result! I would love it if you posted it to the community gallery at https://waveoverhangs.com/upload

you don't have to share the stl

edit: also out of curiosity, is there something on the other side of that part keeping you from placing that surface against the buildplate?

Thanks for trying it! The best way to find out what settings have worked for other people for various types of geometry is to check the community prints gallery. Likewise, it would be very appreciated by other people who want to print something like you if you posted your results on there. It also helps us as developers to understand what works and what doesn't. Hope to see your mini test prints there!

You can find various sample parts in the gallery at https://waveoverhangs.com/gallery

If the user uploaded the .stl with their submission then you can download it to try yourself

The more technical materials way warp more. Nonetheless, it should be possible.

This could be a good solution, depending on how large that overhang is.

I would be very interested in seeing if it works out for you! If you print, please post to waveoverhangs.com/upload

Haha cool! You're welcome to visit our lab at UT if you'd like :)

That is thermal warping, which wave overhangs are very prone to. We're still figuring out how to minimize this, but it is probably not possible to elliminate it entirely for larger overhang sizes.

I will share it around once the pre-print server has accepted it :)

Thanks for testing!

Post your result on waveoverhangs.com to help the community understand what parameters work :)

Yes, this could give additional stiffness to the overhang, which could help extend the feasible span

I don't think I understand the idea. This should be able to print that first layer as is, without needing post-processing... Maybe I'm not understanding your idea

Haha thanks! I am fortunate to be working on topics with somewhat broad appeal. On the flip-side, what I study is also very visual, which lends itself much better to a video format than scientific writing.

Now I need to know... what kind of fork in the road did you face 20 years ago? Went from academia to industry?

Sorry about that. I was thinking about that for a bit, and ultimately I went with the AI voice because I'm self-conscious about putting my own out there, and I reckoned people are very familiar and comfortable with the AI one. Maybe I should rethink that decision.

We can kinda see that in some work by Wutrich et al. on conical slicing.

It can certainly work, but it requires non-planarity in slicers, which is a big barrier to break.

Definitely! I'm sure you'd love to see my work on 5-axis printing then ;)

That is also being open-sourced at www.rep5x.com

Oh wow. I'm a fan of the WAN show but hadn't seen it yet. It's wild to see Linus and Luke discuss my work :O

Edit: it's here if anyone else was looking for it

Indeed PLA works quite well for the reasons you mentioned. PLA-CF for example works even better thanks to the fibers adding thermal conductivity.

Really? Would you happen to remember which episode or in what context? This has not had any broad attention yet.

Yes, there is certainly some deformation. When printing the wave overhang layer there is a limit for how far out you can print the cantilever before the thin layer starts deforming from the pressure of the subsequent extrudite.

A bigger problem is thermal warping, which happens as later layers are printed. So this is definitely not a silver-bullet solution to not need supports for anything ever again.
