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.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
