RAPID prototyping, NEW product development, UNIVERSITIES & colleges, and PROTOTYPES
According to the Wohlers Report, last year marked another milestone: China purchased 9.8 percent of all rapid prototyping machines, moving into the third spot and ahead of Germany (7.2 percent). He said 120 people work in research and development for RP at Huazhong University of Science and Technology, which is probably the largest research effort in the world. Wohlers also outlined aggressive development work in the metals sector to do so-called direct manufacturing, which uses RP to build finished products.

RAPID prototyping, ARTIFICIAL joints, and PLASTIC surgery
Rapid-prototyping machines are, in effect, three-dimensional printers. They build up layer upon layer of a plastic, ceramic or metal, either by squirting the material out of a nozzle in a controlled way or by melting successive layers of powders using a laser. Originally developed to help designers and engineers visualize their inventions before going to the trouble of actually building them, the machines have now become so sophisticated that it is possible to print devices with moving parts. Medical and dental specialists were quick to spot an opportunity. Rapid-prototyping machines have, for example, shortened the casting process for facial and cranial plates used in reconstructive surgery, says Robin Richards at the department of medical physics at University College, London. Terry Wohlers, an American rapid-prototyping expert, believes it is only a matter of time before such machines become common fixtures in hospitals, with doctors and surgeons using them almost as routinely as they currently use X-rays. Wilhelm Meiners and his colleagues at the Fraunhofer Institute for Laser Technology in Aachen, Germany, are one group working to extend the technology to print reconstructive facial plates and even load-bearing artificial joints, such as hips, which could be customized for each patient. Meanwhile, researchers at Advanced Ceramics Research in Tucson, Arizona, are developing rapid prototyping to create replacement bones, with funding from America's Office of Naval Research.
The article reports that BKV Group, Dutch heavy lift and wind energy specialist has diverted its new Liebherr LTM 1750-9.1 from a job in nothern Germany to clinet Lagenwey Wind erect a new design of wind turbine. The LTM1750 placed the lower tower sections configured with the main telescpic boom. The Lagerwey L100 2.5MW turbine has a rotor diameter of 100 meter.

PROTOTYPES and BUSINESS enterprises
Focuses on the prototype factory Hoffmann Modellbau in Lichtenfels, Franconia, Germany which specializes in rapid-prototyping and rapid-tooling. Prototyping methods used by the factory; Modifications in production engineering that Hoffman Modellbau has executed; Examples of prototype projects the factory has undertaken.
PROTOTYPES, NEW product development, and CONTAINERS
The article focuses on creation of an innovative drinks container CrazyCan by product designers in Germany with help from rapid prototyping specialist Proto Labs Inc. The container can be opened and closed with just one hand in contrast to the present beverage cans in usage which use both hands. Two services are provided by Proto Labs including supplying of prototypes and supplying of injection-moulded plastic parts.

INDUSTRIAL research laboratories, REFRIGERATOR industry, and NOISE measurement
The article reports on the opening of a new research and development center by German refrigerator and freezer manufacturer Liebherr at its facility in Ochsenhausen, Germany. The center will provide engineers with prototyping facilities and equipment for climate and noise measurement, including climate chambers, acoustic test rooms, and X-ray room. More than 200 business partners from around the world attended the opening ceremony in October 2008.
The article deals with the use of fused deposition modelling (FDM) in vehicle design prototyping at BMW AG plant in Regensburg, Germany. It notes that the plant's department of jigs and fixtures used FDM to build hand-tools for automobile assembly and testing. Financial advantages of using FDM include cost reductions in engineering documentation, warehousing and manufacturing. It also mentions that the plant uses FDM to enhance the ergonomics of its hand-held assembly devices.
AUTOMOBILE industry, AUTOMOBILE industry workers, INDUSTRIAL design, and TOOL design & construction
The article reports on the benefits of using fused deposition modeling (FDM), a technology used by the BMW AG plant in Germany for its vehicle design prototyping. The plant also has employed FDM in direct digital manufacturing and in the fabrication of hand tools for automobile assembly and testing. The adoption of this technology resulted to enhanced ergonomics of hand-held devices and reduced fatigue to workers who are operating these tools.
