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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
