In this episode of Deep Tech 101, we journey from digital models to real-world parts as we unpack the science and engineering behind 3D technologies. You’ll learn how computational geometry drives CAD and mesh processing, why additive manufacturing spans plastics to metals, and how advanced sensors reconstruct objects in 3D. We’ll also explore immersive visualization—from VR and holographic displays to AI-driven design automation—and survey applications in aerospace, medicine, and cultural heritage. Tune in for your graduate-level primer on the tools reshaping how we create, inspect, and interact with the physical world.
