Lattice structures

A lattice is a thin truss-like shape that you can use in additive manufacturing (3D printing) to create a lightweight part that still maintains its structural strength and integrity. When you create or edit a topology optimization solution, you can select one of several lattice structures that are supported by Materialise 3-matic software. The appropriate structure to choose depends on your design needs.

Cubic (CUBIC)	Body Centered Cubic (BCC)	Face Centered Cubic (FCC)
Octahedral (OCTAHDRL)	FCC+OCTAHDRL (OCTET)	BCC+CUBIC (BCCCUBIC)
FCC+CUBIC (FCCCUBIC)	BCC+FCC (BCCFCC)	BCC+FCC+CUBIC (BFCUBIC)

Note:

If you include a lattice structure in your solution, you cannot use the DMRLAW bulk data entry in user-defined text to define a penalty function. For more information, see DMRLAW.

Where do I find it?
