Skilling Program on IDEA Lab

Day 5 of the Skilling Program for Host Institute Students focused on 3D Printing Technologies and Filament Evaluation. The session was conducted by Dr. S. Benjamin Franklin, Department of Mechanical Engineering, SRIT. The session provided detailed insights into various 3D printing filaments, their properties, evaluation methods, printing temperatures, extrusion settings, nozzle size considerations, and real-time industrial applications. Students gained in-depth knowledge about ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid/Polylactide), Carbon Fiber Filament, and Nylon Filament, along with their strengths, limitations, and suitable application areas. An overview of materials used in 3D printing was also discussed, including plastics, powders, resins, metals, carbon fiber, and biodegradable materials. The session further covered major 3D printing technologies such as Stereolithography (SLA), Selective Laser Sintering (SLS), PolyJet, Fused Deposition Modeling (FDM/FFF), Digital Light Processing (DLP), and Multi Jet Fusion (MJF), highlighting their working principles and industrial relevance. Additionally, the discussion emphasized the global impact and economic growth of the 3D printing filament industry, reflecting its expanding role in manufacturing, healthcare, automotive, aerospace, and product prototyping sectors. Students were also introduced to popular 3D design and slicing software tools such as Bambu Studio, Autodesk Fusion, Autodesk Tinkercad, Blender, and BrickLink Studio. The session was highly informative and strengthened students’ understanding of additive manufacturing materials, processes, and design tools shaping the future of modern engineering.
