My initial thought about using the prototype materials was the thermal risks; meaning brittleness and prone to shattering in the extreme cold Martian temperatures. But I recalled a recent environmental test done to an SLS prototype housing. It was placed in a cold chamber at -55°C and an impact test was run, simulating a sharp impact at extreme cold. The housing was designed with a 2mm wall thickness, and the SLS didn't even dent, let alone shatter. And while Martian climate can exceed -55°C, that was the lowest limit of our chamber's capability. But I'm convinced; at least for SLS.
Jenn, Contour Crafting's potential blows my mind. I mean, 3D printing whole buildings? It's still under development and started out as a mold-making technology for constructing large industrial parts. The inventor expanded the concept to a method for building quick emergency shelters after disasters, such as Hurricane Katrina or major earthquakes. The website says it can produce structures such as houses or larger multi-unit buildings, and that "embedded in each house [are] all the conduits for electrical, plumbing and air-conditioning." That's amazing enough, but the process is also designed to use naturally occurring local materials like clay or plaster. That's a big one--no expensive engineering-grade plastic needed. Here's the inventor giving a TED talk: http://www.youtube.com/watch?v=JdbJP8Gxqog
Yes Beth, I agree. It seems like a month or so ago we were talking about similar things and now here they are here. It just begs the imagination to think about 2 years from now or 5 or even 1 year. I knew this would be big, but it's blowing up!
Defintely out of this world examples of 3D printing. Very cool that this technology is playing a role in space exploration. It really confirms how far the materials have come in terms of choice and durability/reliability that they are even an option for such serious engineering.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
