Additive manufacturing, also known as 3D printing, is a rapidly growing technology that allows users to create complex objects layer-by-layer using digital designs. This educational program introduces participants to the fundamentals of 3D printing, focusing on fused filament fabrication (FFF) and Bioprinting, to make the technology accessible and engaging. FFF, the most common and beginner-friendly form of 3D printing, uses heated thermoplastic filament (such as PLA or ABS) extruded through a nozzle to build objects layer-by-layer. Participants will learn how to set up an FFF 3D printer, load filament, calibrate the build plate, and troubleshoot common issues like warping and under-extrusion. bioprinting, which uses bioinks made from living cells and biomaterials, introduces learners to the intersection of biology and additive manufacturing. While real cells will not be used for safety reasons, participants will operate bioprinters with simulated bioinks like gelatin or agar to create tissue-like structures and explore the potential of bioprinting in medicine and research. The program emphasizes hands-on learning through project-based activities where participants design objects using CAD software, prepare files with slicing programs, and troubleshoot their prints. Example projects include creating keychains, figurines, prosthetic models, and gel-based tissue scaffolds. By combining technical instruction with creative exploration, the program helps participants develop problem-solving skills, spatial awareness, and a foundational understanding of 3D printing, inspiring them to explore the exciting possibilities of additive manufacturing.
