Crude oil for August delivery fell 11 percent, to $128.88 a barrel last week on the New York Mercantile Exchange, the biggest one-week drop in four years. Futures had reached $147.27 a barrel on July 11, the highest since 1983. And the price of oil is going to keep dropping, says a prominent energy analyst. Edward L. Morse of Lehman predicts a plunge to $93 a barrel. Declining demand will contribute to a build-up in inventories. One of the biggest drops will come in China, which had been feeding the fire. Plus there is some new capacity coming on line. The swing in oil prices upward was more exaggerated than normal because of rising speculation on oil and other commodities by investors who no longer could find good bets in real estate, or in the stock market. Some $90 billion of new cash reportedly moved into commodity funds in the past 18 months. A drop in short-term oil price speculation will help move tags down.

The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
