SpaceX Launches Supplies to ISS, Including Its First 3D Printer

A "flawless" launch early Sunday from Cape Canaveral has sent a load of supplies on its way to the International Space Station aboard a Falcon 9-lofted SpaceX Dragon capsule. Food, care packages and provisions for NASA's astronauts make up more than a third of the cargo onboard Dragon. But the spacecraft also has experiments and equipment that will eventually help scientists complete 255 research projects in total, according to NASA. In Dragon's trunk, there's an instrument dubbed RapidScat, which will be installed outside the space station to measure the speed and direction of ocean winds on Earth. Among the commercially funded experiments onboard Dragon is a materials-science test from the sports company Cobra Puma Golf designed to build a stronger golf club. Dragon is also hauling the first space-grade 3D printer, built by Made in Space, which will test whether the on-the-spot manufacturing technology is viable without gravity.

      3D printing is one of those things that will be pretty much essential for successful manned missions farther away than the moon.

      Once 3D printing develops from it's current "stone knives and bearskins" stage of development and reaches the 21st century, sure. But even once the far off day arrives where we can print in a wide variety of materials (I.E. those suited to the task of the parts being replaced) and assuming it reaches the stage where the printed parts don't require substantial hand finishing for precision... it's highly unlikely to be able to print electrical and electronic components, particularly the IC's that will represent a very large component of the failed parts.
       

      Being unable to fix broken things will be fatal if the nearest spare parts are nine months away, and a 3D printer or two can, conceivably, replace a great many individual spare parts....

      That's why you carry spare parts with you. And why you "design for maintenance". And why you do extensive development and testing beforehand to figure out what parts are most likely to break. And design parts to be reliable. And reinforce the parts where you can. And... well, there's a vast amount of and dedicated sub fields of engineering dedicated to this kind of thing. No professional goes off the beaten path with the attitude of "oh well, I'm just gonna die if something breaks". There's a reason why "lack of spares" pretty much has never come up in any serious discussion of lunar colonies or missions to Mars.
