Materials structure can at times have as profound an impact on properties as chemical composition.
PepsiCo is testing a new type of salt whose crystals are shaped in a manner that reduces the amount of sodium humans ingest. Duke researchers developed metamaterials that derive unique electromagnetic properties from their physical structures.
Now, a California startup company called EoPlex is manipulating tiny bricks of materials to enhance performance. EoPlex CEO Arthur Chait says that voxel deposition in the company’s patented High-Volume Print Forming can produce micron-level metastructures. Chait says a Voxel is like a tiny Lego brick. Little bricks made of a given material can be “woven” through the printing process with little bricks made of another material to create metastructures of multi materials that normally don’t bond. Chait says that metastructures made this way offer the potential to increase bandwidth in small antennas.

A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
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.
