I think this is one of my favorite applications for 3d printing. Such excitement on their faces! Looking forward to the day when fanciful, colorful body enhancements don’t even get a second glance.
This is neat. They are experimenting with a variety of cheap, commonly found materials to create 3d printed objects and structures. I know NASA was working on 3D printers that could use moondust as feedstock to print whatever they would need on visits to the moon (vs having to carry everything there) – love to see that same thinking applied to structures here.
