DLP Printing: Historical Perspective and Advanced Technologies

This lecture covers the historical perspective of DLP printing, starting with the first use of single photon polymerization in 3D printing by Hideo Kodama. It then delves into the advancements in additive manufacturing technologies, such as continuous liquid interface production and DLP light engines. The presentation also discusses the Digital MicroMirror Array technology, its pixel sizes, and the complex projection lens involved. Furthermore, it explores the design considerations for DLP printer projectors, aiming for high-resolution structures. Safety measures and practical instructions for operating a DLP printer are also highlighted, along with a hands-on session for the students to experience the process firsthand.
