omw to torture my ender with that thing

once i decide to get out of bed that is

[solid radish]

Cool project \o/

[chilly wadi]

haha, would love to see the results!

even if it failed completely

all data helps

[magic cedar]

sorry im too lazy to config my printer all over again or to look up how to copy the config file

[chilly wadi]

:'(

This is good feedback tho to be honest, looking into how to automate this. Ill let you know

Nice, Have you seen the guy who did something similar with his 4-axis printer?

He deformed the mesh into printable angles, sliced it, then undeformed it

i thought it was a pretty neat way to do it

His looked way eorse than yours though ngl

is this not just a less advanced version of https://github.com/OrcaSlicer/OrcaSlicer/pull/11255

you are effectively just inputting your bridge density manually with your profile settings right?

[chilly wadi]

you mean the RotBot project?

[chilly wadi]

Fair question, but they're solving different geometries.

The PR you linked seem to only tune how bridges are printed. A bridge is a span that's supported at both ends: think of the flat ceiling between two walls. You print across the gap and each line lands on existing material on the far side. Tuning bridge line width and density makes that span cleaner.

Wave overhangs target cantilevers: geometry that's supported on one side only, with nothing on the other side to land on. Like a 90° horizontal overhang coming off a wall. A bridge setting can't help here because there's no second anchor to stretch to; whatever you extrude would just fall into air.

The algorithm anchors each ring of extrusion to the previous ring, not to two pillars. It starts from the supported edge and propagates outward into the unsupported region one ring at a time. That's why narrow-line bridge tricks don't cover this case: there's no span to narrow.

this one https://youtu.be/VEgwnhLHy3g?si=PiDeD1zA--ZnuKaP

ah, the Joshua Bird printer. It indeed does achieve printing overhangs as well, but with a very different method!

I'm currently working on a 5 axis printer project as well (rep5x.com)

but what I like about the waveoverhangs is that everyone can just start using it straight away with their current printers

oh i see, this is changing the geometry of the layers that are drawn to avoid needing anchored sypporting edges, or arc radii? this actually may be exactly what will fix the new bridges anchoring problem but i could be wrong. you should give ianalexsis a dm or make a thread in orcaslicer discord where they can see it

ianaleksis is an orcaslicer dev who added the bridge density stuff as well as the input shaper stuff i trust him for this kinda stuff, but he got stalled because anchor points dont generate perfectly when editing density

[chilly wadi]

Exactly! Thanks for the heads up on ianaleksis. This is currently still a research project mainly by Andersons at the University of Twente. We'll do a bit more finetuning and then hopefully this could be integrated in the main Orca once :)
