FLAC project seeks 40-80% weight reduction in automotive components through 3D printing
January 22, 2017
Engineers at The University of Nottingham are developing lightweight automotive components using new additive manufacturing processes to boost vehicle fuel efficiency, while cutting noise and CO2 emissions as part of the Functional Lattices for Automotive Components (FLAC) project. FLAC aims to achieve significant weight reductions in mass (40-80%) and optimized thermo-mechanical performance in new vehicle components.
The Nottingham team will construct components using selective laser melting (SLM). SLM uses a 3-Dimensional Computer Aided Design (CAD) model to digitally reproduce the object in a number of layers. Each layer is sequentially recreated by melting sections of a bed of aluminium alloy powder using a laser beam. Layer by layer, the melted particles fuse and solidify to form novel structures that can be made up from complex lattices to provide a light-weight component. SLM helps increase functionality and lower the number of separate components in production. This significant mass saving cuts component costs and increases overall vehicle efficiency.

Kiel nanoscale-sculpturing makes metal surfaces strong, resistant, and multifunctional; multi-material joining
September 08, 2016
Researchers at the University of Kiel (Germany) have developed a new process—which they call “nanoscale-sculpturing”—for the surface preparation of metals.
Nanoscale-sculpturing, which is based on knowledge from semiconductor etching, turns surfaces of everyday metals into their most stable configuration, but leaves the bulk properties unaffected. Thus, nanoscale-sculpturing ensures stronger, reliable joints to nearly all materials, reduces corrosion vastly, and generates a multitude of multifunctional surface properties. An open-access paper on their work is published in the RSC journal Nanoscale Horizons.
