3D printing old milk jugs A study led by Joshua Pearce of Michigan Technological University (MTU), Houghton, shows that making plastic 3D printer filament from milk jugs uses less energy—often a lot less—than them conventionally. The team did a life cycle analysis on a typical milk jug made from high-density polyethylene (HDPE) plastic. After cleaning it and cutting it in pieces, it was put through an office shredder and a RecycleBot, which turns waste plastic into 3D printer filament. Compared to an ideal urban recycling program, which collects and processes plastic locally, turning milk jugs into filament at home uses about 3% less energy. “Where it really shows substantial savings is in smaller towns, where you have to transport the plastic to be collected, then again to be recycled, and a third time to be made into products,” says Pearce, associate professor of materials science and engineering. In this scenario, energy savings skyrocket to 70-80%. And, recycling your own milk jugs uses 90% less energy than making virgin plastic Old milk jugs can be recycled into filament for , saving both from petroleum.

The world’s tiniest magazine cover National Geographic Kids claimed its ninth Guinness World Records title for the smallest magazine cover, using patented technology from IBM, Armonk, N.Y., at the USA Science & Engineering Festival in Washington. To create the record-setting cover, IBM scientists invented a tiny “chisel” with a heatable silicon tip 100,000 times smaller than a sharpened pencil point. Using this nanosized tip, which creates patterns and structures on a microscopic scale, it took scientists just 10 minutes and 40 seconds to etch the magazine cover onto a polymer. The resulting magazine cover measures 11 × 14 µm. National Geographic Kids let its readers vote online for their favorite design and they chose the March 2014 cover, which earned the honor of a microscopic National Geographic Kids claimed its ninth Guinness World Records title for the smallest version, visible through a ZEISS Axio Imager 2 microscope. magazine cover, using patented technology research.ibm.com, guinnessworldrecords.com, from IBM, Armonk, N.Y. kids.nationalgeographic.com.
