The next-generation materials approaches used in the Chevy Volt concept car last year are still “very much in play”, says Mark Verbrugge, director of the GM Materials and Processes Lab. Costs of materials used in the Volt, which is due for delivery in two years, will be higher than those normally used to ensure light weight, he said in an exclusive interview with Design News. Reducing mass will be an important strategy to meet the mandate that the Volt must go at least 40 miles without a charge. “If you use more material, you will need a bigger battery,” comments Verbrugge. The vehicle must also sell for less than $30,000, per a mandate from Vice Chairman Robert Lutz. The concept car used a polycarbonate roof, an idea Verburgge confirmed is manageable. The Volt also used a molded thermoplastic hood developed by Sabic Innovative Plastics .The 2010 timeline is doable, says Verbrugge. “You can do it, but at what kind of volumes and what kind of value proposition?’
My thinking is that a version of the Volt will debut by the end of 2010. But it will still be very much of a work in progress. The price probably will rise close to $40,000 and the first Volt will be more of a boutique model than a mass market version. But it’s great to see GM press so hard on the concept.
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.
