Is your feature request related to a problem? Please describe.
The anisotropic properties of 3D prints are frequently exacerbated by shear weakness planes created along the layers, often due to poor melding of an extrudate with the material below, and/or regular cracks/spaces where the material has not reached.
While this can be partially handled by careful management of printing characteristics such as hot-end temperature and flow rate, a major contributor is likely that levels of material are typically stacked flat, whereby most of the weaknesses at a given layer are aligned into a plane.
Describe the solution you'd like
Interlocking extrudates across layers may significantly reduce this problem, and it would be useful to provide some examples and/or tools for doing so. The concept is similar to that of bricks, although it could be interesting to experiment with multiple levels within each layer, or perhaps some kind of woven pattern if we can figure out how to print one.
I'd be interested to know whether this has a meaningful effect on something like the CONVEX tensile test samples, where it could perhaps be applied to modify the alignment of the internal interfaces.
Describe alternatives you've considered
Non-planar layers should typically suffer less from this, although any shape with locally flat layers may suffer from the effects of aligned weaknesses.
Additional context
This concept is from the CNC Kitchen video on Brick Layers, where it is explained and tested in some detail within the context of a relatively standard slicing software.
