Looks like by this time next year, astronauts on the International Space Station could be playing around with their own 3D printer. Made in Space, the contractor hired by NASA to design an additive 3D printer suitable for micro-gravity operation, recently announced that its Engineering Test Unit printer successfully completed simulated launch and microgravity testing at NASA's Johnson Space Center. The next stage of certification is Critical Design Review, which commences this week. According to this new NASA video about 3D printing in zero gravity, Made in Space's printer is scheduled to go up to the ISS with the SpaceX-5 supply mission next June. I can't wait to see astronauts' contributions to this Art of 3D Print Failure Flickr group.
