Abstract

Additive manufacturing has created a paradigm shift in materials design and innovation, providing avenues and opportunities for geometric design freedom and customizations. Here, we report a microarchitected gyroid lattice liquid–liquid compact heat exchanger realized via stereolithography additive...
