There’s a revolution in technology to make planes lighter. Use of composites in the Boeing 787 Dreamliner is well known. Not so well known is a new hexagonal honeycomb core material made of polylactic acid for lightweight panels. The biobased material also has the benefit of a smaller carbon dioxide footprint than oil-based plastics. In the last six months, a Belgian company called EconCore has optimized the production technology to produce PLA-based hexagonal honeycomb cores using a continuous production process. Moments after a core is produced, skin layers are added in a second step of the continuous production process.
Skins could be made from unfilled PLA material to make a mono material panel or, in case a higher performance is required, could be replaced with consolidated flax in a PLA matrix. One potential application is aircraft interiors, which currently use a polypropylene honeycomb material. The new technology was launched at the recent JEC Composites show in Paris.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
