Making with Sound: Manufacturing Functional Cellular Materials and Lightweight Structures via truly SFF (Solid Free Form) fabricationWednesday (07.10.2020) 18:00 - 18:30 Part of:
Solid Free Form (SFF) fabrication, also known as Rapid prototyping (RP) or Layered Manufacturing (LM), creates arbitrary 3D shapes directly from Computer-Aided Design (CAD) data. It has been around for two decades now. From its early age it demonstrated tremendous advantages for the Computer-Aided Manufacturing (CAM) industry compared to traditional manufacturing methods such as CNC machining or casting. The venues for exploration appeared endless until users started to hit a ceiling; the name ‘rapid’ became almost ironic because the layering process is very slow, the palette of materials to handle is limited and the advertised label ‘net-shape’ is ‘near-shape’ – on a lucky day-. We are now over the hype of SFF, RP and LM but still need to create heterogeneous structures that have intrinsic multifunctionality. The Multifunctional Materials Manufacturing Lab in Loughborough University works on new manufacturing methods, including the use of ultrasound and other external fields, for cellular materials that allow a truly free form fabrication and the engineering of composition and structure for the creation of materials that are smart, responsive to their environment and possess synergistic properties that enhance their behaviour. These types of high performance materials offer great promise in fields such as bioengineering, food technology and transport (i.e. automotive and aerospace).
