Volumetric 3D Printing: Principles and Applications

This lecture introduces the concept of volumetric 3D printing, focusing on the advancements in single photon printing technology. The instructor explains the limitations of traditional 3D printers, the Beer-Lambert law, and the Radon transform in CT imaging. The lecture covers the backprojection and filtered backprojection techniques, as well as the challenges in sampling the Fourier space. It also discusses the practical aspects of volumetric printing, including pattern filtering, feedback-assisted printing, and applications in bioprinting and ceramics. The presentation concludes with a comparison of printing speeds and the heat resistance of fabricated objects.
