Continuous Liquid Interface Printing

This lecture introduces Continuous Liquid Interface Printing (CLIP) as a revolutionary 3D printing technology that overcomes the limitations of traditional methods by using a mobile liquid interface. The instructor discusses the transition from Stereolithography (SLA) to CLIP, highlighting the rapid, large-volume, and thermally controlled production of 3D objects. The presentation covers the challenges faced in SLA, such as heat dissipation and limited cooling options, and explains how CLIP addresses these issues through a UV-curable resin floating on a flowing oil bed. The lecture also explores the benefits of the oil, including its recirculation for temperature control and filtration to enhance print quality. Additionally, the instructor showcases the mechanical properties and surface roughness of printed samples, emphasizing the isotropic nature and high quality achievable with CLIP technology.
