Lecture
This lecture discusses a novel approach to 3D printing known as volumetric printing, which eliminates the traditional layer-by-layer method. The instructor introduces the concept of layerless printing, highlighting its advantages, including significantly reduced printing times—from hours to mere minutes. The lecture covers the principles behind this technology, drawing parallels with computed tomography (CT) imaging, where measurements are taken from multiple angles to reconstruct a 3D object. The instructor explains how light can be used to polymerize resin in a volumetric manner, allowing for the creation of complex structures without the need for support materials. Various applications of this technology are explored, including bioprinting and the production of intricate designs. The lecture also addresses the challenges associated with volumetric printing, such as the need for precise control of light exposure and the properties of the resin used. Overall, this lecture provides a comprehensive overview of the advancements in additive manufacturing and their implications for future technologies.
