Infill bone structure #9201

Open matzejo opened 3 years ago

matzejo commented 3 years ago

Is it possible to implement something like an infill pattern inspired by bone structures?

Hi @matzejo thank you for your feature request. Can you explain why you want an infill pattern inspired by bone structures? And could you add the picture in a comment, I can't open the link.

Shure :) Screenshot_20210129-132233.jpg

You can download the whole pdf on orbit.dtu.dk Screenshot_20210129-132546.jpg

Here's the actual link to the PDF the OP was referring to, without all the Google link-bloating/-tracking stuff: https://orbit.dtu.dk/files/128479821/WuAagSig17.pdf

It's fortunately considerably higher resolution than the image provided.

A bone structure is optimised for rigid parts without using to much material. The gradual filling steps are fine but they work primary for top and bottom layers. There is a lag on the side wall support. Maybe a kind of cellular structure will also work with big bubbles in the middle and small bubbles close to the walls.

Thanks, I will discuss it with the team. Keep you posted!

fvrmr commented 3 years ago

We discussed it with the team. We all think it is very cool. But we also see that it is very complex and would take a lot of time to implement. So that why I will defer this issue.

I saw something similar, it can be implemented it the "bone structure infill" wouldn't be implemented. https://www.youtube.com/watch?v=hq53gsYREHU

@Matszwe02 see also https://github.com/Ultimaker/Cura/issues/6954

Saw this while searching for the gradient infill, but this would be much better for functional 3d printing.

However, it would need to somehow input where there would be force on the model, and in what direction it would be in. I could see a whole other program creating a normal map that, instead of surface normals, represented the direction and magnitude of force on different points of the model's surface.

Hi 👋, We are cleaning our list of issues to improve our focus. This feature request seems to be older than a year, which is at least three major Cura releases ago. It also received the label Deferred indicating that we did not have time to work on it back then and haven't found time to work on it since.

If this is still something that you think can improve how you and others use Cura, can you please leave a comment? We will have a fresh set of eyes to look at it.

If it has been resolved or don't need it to be improved anymore, you don't have to do anything, and this issue will be automatically closed in 14 days.

Hi. As github bot assigned stale in this feature request, maybe creating this request also in PrusaSlicer will be ok? I think it's a great idea to enhance infill, so let more developers know of this enhancement.
