Unmanned Aerial Vehicles Fly Via Additive Manufacturing

The materials have been costly, but the earlier machines were, too. Added to that, because items are produced one at a time the per unit cost tends to be higher than unit costs of a high-volume manufacturing process. And that's exactly why this technique is still limited mostly to specialty and race cars, not volume automotive manufacturing.
Direct Laser Sintering technologies as a means to help Unmanned Aerial Vehicles has definitely been on Design News' radar screen for a while and is a great application for this technology. We wrote about one of the first UAVs built with this method taking flight this summer--SULSA,the Southampton University Laser Sintered Aircraft, which was printed using the EOS EOSINT P730 nylon laser sintering machine.
Curious how expensive this process is. You mention aerospace, medical and dental, where high costs can presumably be absorbed. Given the durability and ease of assembly (by aggregating more subassemblies into one piece), DLS seems like it should have huge uptake in automotive, but I'm guessing at this point that it's just too expensive.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
