I am especially interested in the optimized support structure (slide 3) which shows a dramatically reduced amount of support structure material being used. This is can be very significant for certain applications. Not only will this save money (less material used), but will also allow for a much faster cleanup of parts (saves time). In addition to this, certain designs have very delicate features. By creating a minum amount of material to remove on these delicate features, part breakage and damage can also be reduced.
Although I listed it last, the ASTM standards effort to determine the mechanical properties of materials made with AM processes just might end up being the most important of these. There's continuing debate in the industry about the strength and durability of materials made by layering, and a metric for discussing and assessing them is a good start.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
