Foundations of Resin 3D Printing: Stereolithography and Material Jetting

High-precision additive manufacturing requires a solid grasp of how light interacts with liquid resins to create solid objects. This course provides a comprehensive written guide to the two primary photopolymer processes used in the industry today: Stereolithography (SLA) and Material Jetting (MJ). You will move from understanding basic chemical reactions to executing complex workflows for professional-grade prototypes and parts. By the end of this course, you will have the knowledge to navigate the entire resin printing lifecycle, ensuring high-quality surface finishes and dimensional accuracy for your projects. What you'll learn: - Understand the fundamental principles of photopolymerization and resin chemistry. - Prepare 3D models with optimal orientation and advanced support structures. - Differentiate between the mechanical properties and use cases of SLA and Material Jetting. - Apply essential post-processing steps including solvent washing and UV curing. - Practice modern safety protocols and sustainable resin disposal methods. - Identify the best applications for resin-based printing in engineering and design. The course begins with foundational terminology and hardware overviews, followed by detailed written explanations of prep, print, and finishing stages. This structured approach ensures you build a reliable mental model of the manufacturing process. This course is designed for beginners and hobbyists looking to enter the world of resin 3D printing; no prior experience with additive manufacturing is required.
