Lattice_Karak: Lattice structure generator for tissue engineering, lightweighting and heat exchanger applications
S. Kamal Krishnam Raju, Prasad S. Onkar
Abstract
Lattice structures result from biomimicry to create strong and lightweight materials. Triple Periodic Minimal Surface (TPMS) are complex geometry lattices which are highly challenging to design them using computer-aided drafting tools. Lattice_Karak resolves this problem by providing open-source software for generating TPMS. It has all the features for generating and modifying TPMS like density grading, cell size grading, hybridization and hierarchical unit cell. It also exports the generated TPMS into an STL file for further modeling and additive manufacturing. Lattice_Karak can generate scaffolds, heat sinks and porous structures, making it an excellent application for tissue engineering, lightweighting and heat exchanging.
