With its EBM S400, Stratasys Inc. has ushered in a new way of making titanium parts. Producing fully dense parts in Ti6AL4V and Ti6AL4V ELI, the Electron Beam Melting technology eliminates the common barriers to working with titanium. Stratasys is the North American distributor for this unique rapid prototyping device that is manufactured by Arcam AB.
"The high speed electron beam system is the next generation of additive fabrication technology for rapid manufacturing of titanium parts," says CEO Scott Crump. "The machine creates parts comparable to wrought titanium and better than cast titanium, with a 95 percent powder recovery yield, which is unheard of in our industry." The company states that the EBM technology is three to five times faster than comparable laser-based machines. Titanium parts created on the system are accurate, near-net shapes and are HIP treatable. The company also offers cobalt-chrome and has ongoing material development for alloys that include stainless steel. For more information, go to http:// rbi.ims.ca/4933-544.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
