[CATIA] Lattice Designer

 

Enable the industrial usages of lattice structure in high performance parts, providing conceptual and detailed 3D lattice modeling capabilities seamlessly integrated with structural validation, and outputting 3D printers formats

The Lattice Designer role enables the conceptual and detailed design of previously unachievable complex lattice structures for lightweight parts that are produced using additive manufacturing. As part of the world-leading CATIA geometric modeler, it delivers robust and scalable complex lattice design without limitations on model size, visualization or number of cells.

 

An assistant guides the user in the design workflow, from the definition of the regions to infill with lattice, to the creation of the conceptual and detailed lattice geometries. Direct modeling capabilities are available in the role and enable the creation of basic geometries as input of the lattice design process.

 

The lattice data produced by the Lattice Design app are seamlessly integrated with SIMULIA structural validation solutions, providing an unreached confidence in the mechanical performances of the design engineered with lattice structures.

 

The Lattice Designer role enables a direct and high fidelity output to the formats readable by additive manufacturing machines. STL, AMF or 3MF exported data are guaranteed to be watertight, ensuring a quick and reliable processing by 3D printers.

 

Benefits

  • Provide lattice structure design capabilities at all stage of the design process, without limitation of the model size, number of motif, visualization

  • Guide the user in the design workflow thansk to an assistant, from the definition of the regions to infill with lattice, to the creation of the conceptual and detailed lattice geometries.

  • Create basic geometries or modify the input geometries with direct modeling capabilities

  • Seamlessly integrate the lattice design with structural validation (Mod | Sim)

  • Provide 3D printers with the best suited output format for production, watertight guaranteed STL, AMF and 3MF output, ready to print
