PM helped shave nearly 20 percent off the cost of a lawn mower blade-stop assembly, which won the grand prize in the competition's lawn-and-garden category. Previously, the assembly's drum and pulleys had been machined, cast and stamped. Burgess-Norton Mfg. Co. used PM to add features that ease assembly to the mower blade. Among them are a molded key on the pulleys and hexagonal pockets on the drum. The pulleys are also sinter bonded together into a single component. Burgess-Norton forms the parts to a density of 6.9 g/cm3 with an ultimate tensile strength of 280 MPa and an apparent hardness of 50-80 HRB.

Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
