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.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
