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.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
