These springs are made to help integrate components such as flanges, squares, hexes, rounds, bearing sets, gears, splines, bellcrank arms, threads and other machinable shapes into one piece. The springs also allow incorporation of consistent spring rates, precise payloads and multiple integral coils (multi-starts) that ordinary springs don't provide. They can be used as compression, extension, torsion, lateral translation and lateral bending springs, can be made out of machinable metals such as aluminum, stainless steel and titanium. They have no internal stresses to overcome before deflection occurs, since they can be configured to provide very precise, linear deflection rates with almost no residual stresses.

Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
