I agree with Jayna...this 3D printing PR is getting really annoying...do you really expect me to design my own chair and print it at home for few thousands dollars??? and even at that price it would be very lousy chair made out of metal or plastic and no movable parts not to mention sophisticated functions like massage or heating...Kris

Pardon me if I remain in the skeptical corner.  Once again, a potentially valuable tool or process is being buried in hype.  What kind of metal properties will these sintered particulates (with some residual binder) have?  How much will the kiln (mentioned so casually in the article, and not at all in the video) cost?  (For anything other than solder it has to reach a whole lot higher temperature than your kitchen oven!)  If you want two different metals in the same piece, what will the interface look like?


The problem with the hype about 3D printing is that it ignores all these and many other fundamental subtlties of materials processing (thermal history, mechanical working, etc. etc.).  There are some applications for which these won't matter: most items of art don't depend on a precise annealing schedule, for example, nor do they need high purity or strength.  But 3D technologies are being sold (hyped) as if these issues didn't exist.  WHy would one make a motor (which uses several different metals and insulators) this way instead of buying one with optimized properties for a small fraction of the cost?

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
