FLatt Pack - AM lattice design



The Functional Lattice Package (FLatt Pack) is software I developed at the University of Nottingham for the design of lattice structures for additive manufacturing research.


My paper on the operation and capabilities of FLatt Pack was published in the journal Additive Manufacturing. You can download the accepted manuscript here.


I am happy to share FLatt Pack with academics and researchers for new collaborative projects. A trial version can be downloaded from the FLatt Pack Git repository.



FLatt Pack features


  • 23 lattice cell types, including surface-based cells, strut-based cells, and honeycombs.
  • Cell size and volume fraction control, including functional grading and user-defined volume fraction distributions.
  • Choice of standard lattice shapes or import a geometry to be latticed.
  • Export lattice design as an STL for printing or an FE mesh for analysis.
  • Inbuilt triangle reduction to minimize STL file size.
