    A Dynamic Panel Discussion with the Digital Foam Architects Network

    Host Fabian Alefeld moderates a panel with Nick Florek of General Lattice, Dr. Dave Krzeminski of EOS, Pierre Gonnetan of Arkema, and Mike Schorr of DyeMansion to discuss the Digital Foam Architects Network. The group explains how inverse design and collaborative 'digital tooling' simplify the development of polymer lattice structures by coordinating materials, printing, and post-processing. They highlight specific challenges in achieving uniform color adhesion and smoothing, noting that post-processing decisions must influence early design choices to ensure repeatability. The panel identifies medical devices, aerospace, and consumer goods as key industries benefiting from these performance-based lattice applications.
