Look for intense collaborative research efforts over the next 10 years to improve additive manufacturing technologies for use in high-tech aerospace applications. The cost of aerospace components is boosted dramatically due to the amount of material beyond the finished geometry that must be removed during manufacturing-often 90 percent or more, according to Chris English, an engineer with GE Aviation. As a result there is increased interest in the potential to use additive manufacturing technologies that were originally developed for rapid prototyping applications.
One example is a project at the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. Researchers there are looking at the potential to produce net shape low-density cellular metal structures from layer-based additive manufacturing of metal-oxide ceramic slurry followed by post-processing in a reducing atmosphere. A ceramic suspension would be direct printed in a research investigation. Many issues remain, however, with existing additive manufacturing systems including materials available, poor surface finish, difficulties in removing support systems, and inability to make large parts.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
