We can consider a lattice structure a model or a three-dimensional pattern that is repeated to fill a volume.

We can find natural examples of lattice structures in our bones, in the honeycomb of beehives, fungi mushrooms, and bubbles (as Voronoi structure). All these examples are nature's way to provides lightweight structures. 

Using generative design and changing various process parameters, lattice structures can be designed with specific electrical, mechanical, thermal, and acoustic properties. For this reason, such structures have been researched mainly for technical, rather than artistic,
applications.

In addition to the lattice structures that software can create, Generative Design can be used to realize supports for mechanically sound and aesthetically compelling parts. Additive Manufacturing technologies, especially Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS), metal Binder Jetting, and lately Fusion Deposition Modelling (FDM) upgraded toAtomic Diffusion Additive Manufacturing (ADAM), allow the printing
of sculptural or mechanical parts with lattice structures without the necessity of support for the model. I will discuss the design and production processes of 3D-printed lattice structures based on my latest artistic work.

Refreshments served at 3:45 PM
