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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
