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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
