A Method for Generation of Random Lattice Structure for Additive Manufacturing

摘要

Additive manufacturing technologies provide us new opportunities to fabricate a product with much more complex geometry and architecture that conventional manufacturing ones such as turning, milling, grinding, casting and molding do not have the ability to implement. Hence, lattice structures are becoming more popular and used extensively in the industrial product design to minimize the usage of materials due to the additive manufacture technologies. Lattice structures are formed by the cellular unit of structure repeated regularly or irregularly in a design area. However, the creation and generation of these structures for additive manufacturing in the current CAD environment have many difficulties. Therefore, the paper will propose a new approach to design the lattice structure, especially the random one. This approach allows helping product designers to design and generate lattice structure randomly based on the Voronoi diagrams..
