Hi @Cuq. Yes, the Schwarz P isn't really much good as a general infill but apparently it has potential applications in medicine and other niche areas. Personally, I will keep using gyroid as my day-to-day infill.
Hello,
I'm testing your last Cura master with Schwarz D infill and it's the best I've got tryied. Gyroid was good but this one is better for mechanical and really faster. And your others options are very great and convenient. I hope Ultimaker uses your work.
Thanks a lot !

Hi @Noisettetbou, thanks for the feedback. What kind of objects are you printing using the Schwarz D infill?
Hi,
I print mechanicals objects and I'm working on a project of blocks of construction for houses who needs this kind of infill. Anyway even if I print a character or a little piece, I would prefer use this kind of infill for his speed ans his strong.

I've been studying triply periodic minimal surfaces (TPMS) quite a bit.
There are numerous other surfaces. This site has a very extensive list:
http://facstaff.susqu.edu/brakke/evolver/examples/periodic/periodic.html#gyroid
One important criterion is that they have no overhang, but even gyroid surface violates the overhang angle.
We might want to relax the criterion of being minimal, and alter the gyroid slightly in order to satisfy overhang constraints.
However, that would require some mathematical trickery which I haven't delved into yet.
Another idea is to rotate the patterns if there is one orientation in which there is considerably less overhang.
@Noisettetbou Please share any results you found. I am very interested.
It seems to me the Schwarz D is very anisotropic; does it have those straight diagonal lines only in one direction?

@bagel-orb Hi. My results are that this infill is very fast and strong. The straight lines change of direction (rotation of 90°). I don't doing some pressure tests but I think is rigid like gyroid.
Note that with the Cura master version you can set the infill vertical scaling.
According to my analysis the Schwartz D is exactly as printable as the gyroid, with normals concentrated around 45* overhang. The Schwartz D surface is definitely more stiff, though, seeing as it has straight lines in it.
Can't find an easy stl for the Schwartz P surface for my automated analysis. Perhaps I will have to generate it myself in MATLAB just like I did for the gyroid.

I verified that the Schwartz P also has the same shape of the overhang angle occurrence plot.
Are there more TPMS which are defined by an implicit function?

Hi, Sorry for being naive, but where can I find the code for Schwarz P infill implementation? I was going through the github files and couldn't find it.
I would like to try implementing few custom infills, and was hoping to get direction from the your implementation.
Many thanks!

Take a look at the "mb-testing" branch:

hi, does anyone know how I can add these fillers to my Ultimaker CURA? or does anyone have a way to add these fillers to the CURA directly? THANK YOU VERY MUCH

There's no practical way to do it. They exist only in @burtoogle's fork of Cura.

And do you know how I can introduce or what I can do to add those gitHUB patterns in cura? I don't know how to do it
Why not just use the mb version of Cura? It's okay to have multiple versions installed at the same time.
If you are a software programmer you can learn how to use the tools used to create cura. How to build Cura is not trivial even for programmers. There are articles on this forum about how to do it and experts who can help you but they aren't going to teach you the 300 steps. But if you get stuck on a particular step e.g. a linker error, they can offer suggestions.
Instead, why not just use the mb version? The last time I compared the mb version and the UM version, the mb version was much better at nicer looking prints.

Thanks a lot for your work @burtoogle,
I like your new Schwarz D pattern. The Gyroïde pattern is already nice but the Schwarz D pattern are faster and it generate less wobbling movements. On the other hand I am not convinced by the Schwarz P(rimimitif) pattern.
