1. Tough economic conditions will force greater efforts to reduce cost and improve product effectiveness through accelerated design engineering. Value engineering processes took a back seat when business was booming. Now efforts will be redoubled to find more efficient assembly systems and more cost-effective materials.
2. Injection molding will gain more attention as a design tool, for plastics, metals and ceramics. Advances in materials, simulation and processing technology make injection molding more feasible for difficult (e.g. high temperature) applications. There will be growing emphasis on molders who offer design support and advanced technology, as other molders fall by the wayside.
3. Weight reduction efforts in cars will get far more serious as OEMs such as General Motors finish materials engineering for electric cars, such as the Chevy Volt. The short-term winners will be known materials solutions (e.g., forged aluminum wheels) rather than exotic and very expensive solutions (e.g., large scale use of carbon fiber composites).
4. Medical engineering will rise in importance as OEMs continue to move away from low-margin manufacturing. The troubles in the car industry received huge press in 2008, but this is a trend established more than 20 years ago.
5. The Japanese companies will lead in new engineering applications for plastics using natural feedstocks in place of hydrocarbons. Sixty per cent of the interior components of Toyota’s new hybrid will be made from plant-based plastics. Parts include scuff plates, headliners, and seat cushions.
The Strati EV car printed at the IMTS show is made of SABIC's LNP STAT KON AE003. SABIC tells Design News why this carbon fiber-reinforced compound was chosen by Local Motors and Oak Ridge National Laboratories.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
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.
