Expanded use of additive manufacturing because of newly supported materials The strength of the technology is that it can be used to produce complex individual pieces or parts that are needed in small quantities, says Krger. A classic example from our own product development is a new duct system, known as a transition duct, for gas flows in gas turbines, says Martin Schfer, who has been working with this technology at Siemens CT since the late 1990s. This curved, thin-walled part has very small channels, and its extremely difficult to make it with conventional technologies such as casting and milling. But with additive manufacturing, these metal parts can be produced right from a computer in just a few days, instead of weeks, says Schfer. All rights reserved.

For certain types of turbines, defective burner parts are simply reprinted, reducing repair times by as much as 90 percent. Olaf Rehme of Siemens Corporate Technology also uses one of the super-hard special steels that can withstand extreme conditions. http://www.siemens.com/press/en/presspicture/pictures-photonews/2013/pn201317.phpSiemens AG 2013 All rights reserved.

Hot isostatic pressing (HIP) (HIP) is a manufacturing process used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The HIP process subjects a component to both elevated temperature and isostatic gas pressure in a high pressure containment vessel. Pressure is applied to the material from all directions (hence the term "isostatic"). When castings are treated with HIP, the simultaneous application of heat and pressure eliminates internal voids and microporosity through a combination of plastic deformation, creep, and diffusion bonding; this process improves fatigue resistance of the component. http://en.wikipedia.org/wiki/Hot_isostatic_pressingSiemens AG 2013 All rights reserved.

Proto-Pasta on KickStarter (FDM/FFF process) As the nylon is melted by the laser it encapsulates the carbon fibers, leaving very tiny ends of the fiber protruding from the nylon. Next, the machine applies another layer of nylon over the just-melted layer: As the laser melts the subsequent layers of nylon the carbon fibers become interwoven from layer to layer creating a very strong composite. http://nwrapidmfg.com/blog/2012/06/25/carbon-fiber-fillednylon-a-material-alternative/ (SLS process)Getting fibers running in all directions would be very valuable.

Graphene Graphene can be described as a one-atom thick layer of graphite (carbon). High-quality graphene is strong, light, nearly transparent and an excellent conductor of heat and electricity. adding graphene to polymers which are conventionally used in 3D printing improves the properties of the polymer in many different ways; it improves the polymers mechanical strength as well as its electrical and thermal conductivity Graphenea found that the addition of as little as 0.22 percent of graphene to alumina made it 50 percent more resistant to the propagation of cracks under strainSource: http://www.graphenea.com/blogs/graph ene-news/8689765-graphene-reinforcedalumina-tougher-and-more-conductive-thanplain-aSiemens AG 2013 All rights reserved.

Conclusion Ability to print in a growing number of materials will expanding additive manufacturing reach, especially for direct to part 3D printing. Composite materials are becoming important to addressing many of the limitations of existing materials used in additive manufacturing. Mixed materials have the potential to allow designers to create entirely new products, especially where tuning of material properties is key.Finally! As this is February 13, Be sure to take home sample materials, preferably in a heart shaped box. Siemens AG 2013 All rights reserved. Page 3420XX-XX-XXSiemens PLM Software
