About a year ago, we reported on a team using “two-photon lithography” to 3-D print a teeny, tiny racecar in about four minutes. That was insanely fast--printing a racecar might've been a little sight gag--but now another team, using the same process, has printed a similarly small spaceship in less than a single minute.
A company called Nanoscribe GmbH made the 125µm x 81µm x 26.8µm ship, modeled on the Wing Commander videogame franchise. To create it, a laser zapped layers of photoactve liquid resin in just the right spots, and the material hardened in response. This video shows the process in real time.
