Abstract (en)

[origin: WO2019092217A1] A 3D-printed, woven composite material is formed from a continuous filament. The woven material may comprise two sets of parallel segments formed from the same continuous filament, wherein the parallel segments of the first set cross the parallel segments of the second set in an under-over pattern. A unit cell of the pattern may comprise N segments of the first set and M segments of the second set, and if segment n 1 of the first set crosses segment m of the second set and segment n 2 of the first set crosses more segments of the second set than segment n 1 , segment n 2 may also cross segment m for all n 1 ,n 2 ∈ N and all ∈ M. A method and apparatus for producing such a woven composite material are also disclosed.
