3D Printing - IN SPACE!

in Actifit2 months ago (edited)

A good portion of this video recently posted on Joe Scott's YouTube channel covers the interesting possibilities for 3D printing in space. As pointed out in the video 3D printing has already been on-going aboard the ISS since 2013 for making tools.

As space becomes more commercialized for industry power generation and biomedicine could be using 3D printing. The regolith on the Moon and Mars could be used as the material 3D printed for manned bases eliminating the need for importing construction material to those locations.

But wouldn't you need gravity for 3d printing to work? I need to watch the video!

My understanding is that because layers are being applied the first layer sticks to the print bed and the nozzle is close enough to each layer as it is being applied so the extruded material fuses onto the prior layer before it has enough time to float away.

This video showing jelly being spread to make a sandwich on the ISS seems to demonstrate an analog of that. A material spread on a surface that is weakly sticky is enough to maintain the material in place.
