Patent attributes
A method for the production of an object by additive manufacturing includes inputting a boundary shape and desired mechanical properties for said object, subdividing said boundary shape into a plurality of adjacent work cells, providing a plurality of lattices in a database, each lattice of the database including a geometry and a mechanical property, filling a first one of said work cells with a lattice from the database, the lattice selected based on the correspondence of the mechanical properties of said lattice to said desired mechanical properties of said object, filling the remaining ones of said work cells with lattices from said database to produce a filled boundary shape, each said lattice selected based on: the correspondence of the mechanical properties of said lattice to the desired mechanical properties of the object, and the compatibility of adjacent lattices in adjacent work cells with one another.
