Slideshow: 3D Printing Will Go to Mars

In one program for making replacement parts on the spot for the International Space Station, NASA is testing electron beam freeform fabrication This process, developed at NASA's Langley Research Center, makes metallic structures quickly using an electron beam gun and a dual-wire feed. It has been used to make titanium spars for the F-35 Joint Strike Fighter's vertical tails. NASA is tailoring hardware and processes to make it easier for astronauts such as Dan Burbank, Expedition 30 commander, to use. Burbank (shown here in the ISS Tranquility node) works on the atmosphere revitalization system's major constituent analyzer mass spectrometer assembly. (Source: NASA)

Concerns about extreme Cold

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

Beth, I was surprised to discover the Stratasys/NASA project, and then 3D Systems' testing with Made in Space, which was the spark that began this slideshow. Tough stuff indeed!

I really like the electron beam freeform fabrication that seems very neat. It sounds almost like welding, but forming parts.

I was wondering about the 0-gravity, but they have already done it. Amazing!

That Contour Crafting seems unreal. I bet that's a few years off, but then again you never know.

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!

This is fascinating, stuff, Ann. I'd like to learn more about Contour Crafing. Do you have any idea about what other cool projects they are working on?

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.

To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
