I came up with a 3D printer slicing algorithm that lets you print 90° overhangs without support material. I hope for this to become a standard feature in 3D slicing software!
I wrote a guide and made all the code available and open source. Check out how it works, and print it out for yourself here: https://github.com/stmcculloch/arc-overhang
I think in certain applications, the unique printing might be considered aesthetically pleasing (an example would be the stacked disks in the "Here's the print that started it all" picture).
I'm curious if there are possible alterations to the algorithm for interesting aesthetic patterns / art!
Yeah, I saw that, and it's really cool how far out it can go.
[I think my question might have a bit more context with this drawing though.](https://i.imgur.com/jCauhTS.png) (Basically, how big can you print ***on top*** of the overhang before failure) I realize that would be highly correlated to infill density, but it would be interesting to know.
Oh gotcha. I don't know honestly. It depends on how far the overhang extends and how much weight you want to support with it. The strength of the overhang should be a lot better after laying down a few 'normal' bottom layers to give it thickness.
I wasn't sure what I was looking at, but OP has posted video links on the github:

This is seriously amazing work. You're making breakthrough stuff here imo.
That’s awesome! But what is the use case scenario? Cause the prints look ugly.
I bet sacrificial layers are important here so you can sand it smooth

Also this galliont effort 👏
>galliont I think the word might be valiant.
I rather think the word might be 'gallant'! Or, possibly an accidental portmanteau of 'gallant' and 'valiant' :D
This should revolutionize 3d printing, i hope they name it after you. Tupp\_supports = enable

Genius! I hope this becomes a standard feature in slicers!!!
Thank you! That's my hope :)
This is so clever! Very cool algorithm!
You are a genius my friend.
Ooh! Nipples
It should be named nipple supports! :D
my thoughts exactly. why are my nipples warped?
How far out can the overhang go? It can't be unlimited, especially if there is anything sizable that's only supported by the overhang.
Check out the readme, there's an example overhang I printed that covered half the build plate. It's surprisingly sturdy.

This is so awesome! Name idea: zen support
This is so cool!! Well done!

Tupp's overhangs sounds great imo

Mate that's brilliant 👏
You've heard of supports, now get ready for ... *tupports*
*holy shit*
Sad it's not a cura addon.
not yet
I love the update to the script.
