A group of students from Warsaw's University of Technology Student Astronomical Study Group created the Mars rover Ares 2 using Zortrax M200 3D printers. The four-wheeled, all-terrain rover was designed by the student group to be capable of independently roaming and exploring the surface of Mars. Throughout the development of Ares 2, the students used their Zortrax M200 to 3D print multiple components and parts of their rover, including the wheels and a durable housing for its ultrasonic sensor. The students also 3D printed the rover's gripper and successfully reduced the weight from 33 grams to 20 grams. You can read more on 3DPrint.com: https://3dprint.com/134312/zortrax-3d-printers-mars/
