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.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
