Solid infill pattern setting

[espr14]

1.42.0 b2 win64

While you can change top and bottom solid infill pattern, there is no way how to change internal solid infill. It's always rectilinear. Can you add a setting for this?

If you use Archimedean chord for circular object it is kind a vase mode for circular layer. This brings higher print speed and stronger layer. Other solid infill layers can be also Archimedean chord. The only change would be initial rotation of 180° per layer. This would lead to placing thread between two threads below which could increase strength.

I believe this is a duplicate of #28 as the proposal in #28 is much better than what has been proposed here.

I am leaving this proposal open with the "very unusual idea" tag attached for others to chime in, but I propose to implement #28 instead of making the internal solid infill configurable.

[espr14]

#28 is about perimeters. This is about solid infills.

[bubnikv]

no, they are both about solid infill.

I'm with espr14 - I have a part with a color indicating it is a Solid infill. It is the rectilinear pattern. I would like to change it to the same as the top and bottom infills that I'm using, Octagram Spiral.

OK - I know think what I'm looking at is actually the Bridge infill - I can understand why it is linear, but I was hoping on a small part that is supported, it could have a different pattern.

I'm using PrusaSlicer-2.1.0+win64-201909160915. I was trying to create a hilbert curve solid infill, and I came across (what I think is) the same issue. While all (Fill Pattern, Top fill pattern, and Bottom fill pattern) my Infill Print Settings were configured for Hilbert Curve, I saw that there were rectilinear layers added.

The attached image is an example of a stepped structure. My real intent is to have 100% infill as hilbert curve, which does slice and not have bridging layers, but it still produces a rectilinear layer right before the top layer.

I came across this again when using PrusaSlicer on a different model. I double checked my horizontal shells, and I had 5 Solid layers set for the bottom. However, even the second layer was rectilinear although I had all patterns set to Hilbert Curve.

Any movement on this issue?

I am also very interested in this feature. I am experimenting with translucent filament and how it conducts light.

I very much need to be able to control the 'solid fill pattern' alongside top and bottom.

I'd love to see this added as well. It would be a lot quicker in my batch production.

Same, very interested to see this implemented. Have to use modifiers, and it's very time consuming

Same with me,
I am trying to do the valve and I really need concentric infill for its properties. Is there around at least some dirtyhack?

In your case, I would use modifier to set infill type and density for a specific part.

4 years later, this would still be helpful. I'm printing circular items, and concentric internal and solid infill would be amazing.

Set perimeters to 100 and it should work. Dirty hack :D

I've been printing PHA which really likes to warp. One way to reduce warping is to avoid infill with straight lines. For many objects, I want the visible top and bottom layers to be straight and to prevent warping I want the rest of the infill to be a pattern other than rectilinear or monotonic. This feature would help.
