LatticeWorks

This is a MATLAB toolbox for creating and customizing lattice structures, multi-morphology lattices, and lattices in different coordinates and arrangements.

Getting started

Installation

To install this toolbox, simply run install_me.m found in the main project folder.

Alternatively one can manually install by adding lib and lib_ext folders to the path.

Install dependancies

• Install the GIBBON MATLAB toolbox
• Required MATLAB toolboxes:
  • Image Processing toolbox Optional functionality
• ABAQUS, to run finite element simulations through ABAQUS
• FEBio, to run finite element simulations through FEBio (see also configuration information with the GIBBON toolbox)
• export_fig, to fascilitate the creation of publication quality figures.

Running examples

Examples are contained in the docs folder.

Applications

• Lattice generation for tissue engineering and scaffolds, biomedical devices, energy absorption, etc.
• Generating ready-to-print STL files for 3D printing of lattices.
• Finite element analysis (FEA) using ABAQUS directly in the toolbox, as well as post-processing the results. DEMO_0014_FEA_ABAQUS_Twisted_Cylindrical_Gyroid is an example of FEA on a generated lattice structure, through ABAQUS directly in the toolbox.
• Mapping optimised nonuniform gradient lattices on distributed structural and mechanical properties, e.g. stiffness. DEMO_0013_Mapping_Density_Distribution maps nonuniform gradient gyroid on a density distribution field.
• Creat infill lattice structures within a closed surface, using different lattice types. DEMO_0012_infill_STL_Lattice is an example of this application on a vertebrae model.
