Isogrid, anisogrid, and rhombic composite infill

Now that we started discussing the infill density, let us see how we adjust it, or in other words, create a multimaterial.

Anisoprint composite fiber coextrusion technology allows to create lattice structures due to changing the fiber/plastic volume ratio during printing. It means making grids with different densities to achieve the desired mass, stiffness, or durability parameters.

Aura can create three types of lattices: isogrid, anisogrid, and rhombic. Rhombic is the most simplistic, for parts that do not need excess strength but do need to be lightweight. Isogrid infill is a more stiff structure that tolerates stress coming from different sides, and as you have already guessed, anisogrid structure is the one that bears the most load, but only in one direction, in other directions it is not that durable. In anisogrid infill, one can vary not only the density but also the direction, anisotropy can be high or low according to the angle. It is anisogrid infill that allows to vary both direction of anisotropy (main vector) and its degree.

For example, one can adjust parameters in such a way that the strength in the two directions would differ by 10% or by 500%, depending on the angle between the grid edges.

Different lattices can be used for different areas of the detail to work in a specific manner: this is called a multimaterial.

Now that you are ready, riddle me this: which foxy stands for which type?
