Title: MULTISCALE DENSITY THRESHOLD MATRICES FOR 3D PRINTING
Abstract:
One example includes a three-dimensional (3D) printed object including a first lattice structure and a second lattice structure. The first lattice structure includes a first matrix having a first length, a first width, and a first height. The second lattice structure includes a second matrix having a second length, a second width, and a second height. The second length times two is a factor of the first length, the second width times two is a factor of the first width, and the second height times two is a factor of the first height.
