Users of 4D Additive can now create diverse lattice structures and validate them with simulation tools

Software provider CoreTechnologie has announced another upgrade for its 3D printing software 4D Additive. With the integration of the Nastran interface, users can create diverse lattice structures and validate them with simulation tools in a few seconds.

Apart from the tailored version of this software for 3D printer manufacturer Photocentric, it should be noted that other improvements of the software included for instance, the integration of AI for Nesting as well as the ability to generate repaired and optimized STEP models.

The integration of this advanced lattice module facilitates the files transfer to finite element analysis tools.

The company explains in a press release that the 4D_Additive software provides tools for an easy creation of 20 different 3D lattice structure types. CAD solids can be filled with internal structures and can also be replaced by external structures. In particular, gyroid patterns and trabecular structures to emulate natural lattices, such as found in bones, are used to generate new designs to optimize the weight, stability, stress distribution and shock absorption of components.

The use of different lattice types and the variation of the density as well as a variable cell size over the course of the component allows the adaptation of the geometry to the required properties with simultaneously optimized component properties. In contrast to topology optimization with this approach classical part designs are quickly optimized iteratively and can be validated with simulation tools on the fly.
