Gridify: Anti-warpping for large flat object

[Noisyfox]

This is a native implementation of the anti-warpping method proposed by 野生机设小佬 in his awesome video https://www.bilibili.com/video/BV1eJRiYME6E Huge thanks to him!

The idea behind this is to split layers into grids so the internal stress shrinks each block individually and the overall deformation will be minimised.

Use modifier if you only want to apply this to part of your object.

OK that is awesome! Will be testing this with a bunch of ABS parts that I need to print soon!

I tried Gridify and it works well, it just seems that the pattern angle isn’t quite right ( it looks like the angle might be in radians instead of degrees). Another detail is that it would be nice to be able to set the top and bottom layers to be solid.
Another possible improvement would be for the internal loops to have only one perimeter, to avoid increasing the amount of material too much.

Ah you're right, forgot to do the conversion.

You can use a modifier for that.

This is not possible due to how it's implemented at the moment. Also this feature is mainly designed for solid parts which wraps a lot.

I noticed some artifacts
You can see those strips in the screenshot

I have a suggestion about the name too. Shall we call it Anti-warping instead of Gridify? I think the name is a bit counterintuitive.

Or just call it "Gridify Anti-warping" for the option group and gridify_enabled's label

If I'm not wrong, I think this is only useful for those who want to print 100% infill. Otherwise, we will have enough gaps for stress relief anyway.

Would be better to mention it in tooltip that this is only useful for those who want to print at 100% infill?

I haven’t tested it but I think it can also offer benefits when you have a large flat surface with say 1-1.5mm solid infill then sparse then another 1-1.5mm solid. Basically thick shells

I have some doubts.
But I agree only tests can tell

[hotellonely]

would it be also making the part weaker, probably defeating the purpose of having solid layers?

Absolutely it will be weaker, but it should still be stronger than sparse infill that having dense low enough to not wrap I believe, at least that's what I heard from the original proposer.

Also, anyone can test this themselves. This feature is still much of an experiment and should be used conditionally.

Please check the issue #7610
It describes another way to relieve internal stress in printed parts. It's just that the walls need to be printed like snake across the thickness of the walls. The tension inside the infill can be lowered by choosing a gyroid filling.

open holes can simply be closed with stoppers for the thickness of the nozzle diameter. A little plastic won't create much stress.

I have some issues with the localizable strings...
