As it turns out, 3D printing techniques are perfect for use in space. Printers have become small, compact, fast, and powerful. And, as we've discussed before, a wider array of engineering materials are now available.
Packing for a working trip to the International Space Station, the moon, or Mars must be a lot harder than packing for a business trip to Europe. If all an astronaut needed to take along was a 3D printer with the right software library of tools and spare parts (plus some raw materials), that would make things a lot simpler, and it would probably cut fuel costs by a lot.
But additive manufacturing isn't just for astronauts. The makers of components for fighter jets, commercial planes, and unmanned aerial vehicles are also researching the use of 3D printers to produce end-use and production plastic and metal parts.
Many techniques are being put into play, including various forms of selective laser sintering (SLS), conformal lattice structures combined with SLS, fused deposition modeling, and NASA's electron beam freeform fabrication. One process, done with the Contour Crafting robot, can manufacture structures as large as apartment buildings and hotels using locally available materials such as clay and plaster.

NASA-funded research by University of Southern California professors Behrokh Khoshnevis, Madhu Thangavelu, Neil Leach, and Anders Carlson is exploring how structures on the moon can made using the Contour Crafting robot. Under NASA's Innovative Advanced Concepts program, the researchers aim to develop methods for creating infrastructure, such as roads and landing pads, to support human settlement on the moon. The technology can create structures in situ from local materials, which is especially important for long-term, continuously expanding operations on the moon. For example, the team is exploring a nozzle system that heats lunar soil into a cement-like paste.

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!
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.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Engineers at the University of California, San Diego are designing a robotic arm that takes inspiration from the loose, flexible, yet very strong structure of the armored plates on a seahorse's tail.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
