11. A computer comprising:
a processor; and
a non-transitory storage medium storing instructions executable by the processor to:
receive data representing a beam-based lattice structure and a membrane to be placed on the beam-based lattice structure;
identify intersection points of beams of the beam-based lattice structure with the membrane when contacted to the beam-based lattice structure;
define triangles connecting the intersection points;
identify locations for perforations in the membrane to form a perforated membrane, the identified locations being within the triangles;
generate a representation of an object comprising the perforated membrane that includes the perforations at the identified locations; and
ultimately provide, to an additive manufacturing machine, the representation for building of the beam-based lattice structure and the perforated membrane placed on the beam-based lattice structure.
