It’s amazing to consider the long-term potential of carbon nanotubes as a polymer reinforcement if major issues (cost and health concerns) can be overcome. Research reveals the possibility of cross-linking CNT molecules prior to incorporation in a polymer matrix to form a super composite with a tensile strength of 20 million psi. Single-walled nanotubes exhibit unique electric properties and may be used for miniaturizing electronics beyond the micro electromechanical scale. Big producers are placing major bets on the technology. In Japan, Showa Denko is building a 400 million metric tons per year production plant. In Germany, Bayer is building a 200 million metric tons per year plant. They’re betting they can dramatically reduce the cost of CNTs which had been in the stratosphere as a pilot scale product, say $40,000 per pound. Multiwall nanotubes are down to $50 to $70 per pound now. Prices will drop as new plants come on line. Health issues must also be addressed.
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.
