According to the Made in Space press release, they tested various 3D printers back in 2011. Perhaps they were done on the ISS or maybe even on NASA's 'Vomit Comet' plane. Still it's interesting to see where this will lead!
Good point, elizabeth. But it think it depends on what branch of government. If building on the moon was a matter of national security, there would be a budget for it. The original space program was an elaborate national security effort to keep up with and eventually surpass, the Soviet Union. That's why it was well funded. When the space program was no longer viewed as a national security efflort, the funding dried up.
You're right, Rob, the technology is there...I just don't think the budget is! I used to write about the government space and to my recollection, they had a lot of budget cuts and financial worries there. So perhaps that's why this is all stalled even though the technology is there. With 3D printing and other technologies making things easier and cheaper, perhaps it will get a kick start.
Like you, Elizabeth, I don't have high hopes for the bill, but I like it that the idea is getting discussed. I also like the idea that the tools for creating a habitat on the moon are getting developed.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
