Fig. 2: Challenges of voxelated digital materials and the required scale differentiation.
From: Inverse design of stochastic, voxelated thermo-viscoelastic digital materials
a The two main challenges in representing voxelated, AM material are the extensive number of data points needed to represent macroscale geometries and the stochastic nature of material placement due to manufacturing inaccuracies. This results in smearing between materials and bleeding from one material domain into neighboring domains. b For efficient representation of voxelated digital materials, the geometry is approximated as mesoscale grid points, where each grid point is assigned a material mixture. The microscale voxel layout is a stochastic assignment of base materials according to a defined mixture ratio.
