Fig. 10From: Review of heterogeneous material objects modeling in additive manufacturinga Utilizing TPMS-based unit cell libraries to generate porous scaffolds from the subdivided hexahedral elements [89]. b The generated TPMS scaffolds could be intersected with TPMS libraries again by the distance field to generate hierarchical TPMS scaffolds [90]. c For any complex models, diverse unit cells can be selected or even combined to design the ideal lattice structures [91]Back to article page
