The European Space Agency’s (ESA) Rosalind Franklin ExoMars rover now has a miniature counterpart that you can 3D print at home, called ExoMy. All of the blueprints and software for this rover can be downloaded for free so that anyone with access to a 3D printer can assemble and program their own ExoMy. When built, it stands 42cm high and reproduces many key features of its 2m tall ExoMars, including a drill, solar panels across its back wings and a camera mast. Read more for a video, additional pictures and information.

It also features Rosalind Franklin’s ‘triple-bogie’ suspension design that enables it to cross high obstacles as high as its own wheel, while also keeping them stable on the ground. Each one of its wheels has its own motor, and their tread boasts protrusions to assist traction over rough ground. To steer the rover, you use a gamepad or web browser on a mobile device.

  • Self-developed Silent Motherboard: The Ender-3 V2 built-in self-developed silent motherboard, which has stronger anti-interference, faster and more stable motion performance, silent printing and low decibel operation.
  • UL Certified MeanWell Power Supply: Equipped with MeanWell power supply, produced by the listed company with mature technology, meeting all the needs of fast heating and long-time printing. Moreover, the power supply is concealed in the machine, making it much safer.
  • Effortless Filament Feed-in: Ender-3 V2 adds a rotary knob on the extruder, making loading and feeding filament process much easier; Brand new operation UI system and 4.3" smart color screen greatly improve user experience.
  • Resume Printing Function: Can resume printing from the last recorded extruder position after suffering unexpected power outages, saving your time and reducing waste.
  • Carborundum Glass Platform: Enable the hotbed heat up quicker and prints adhere better without the warping. Ultra smoothness even on the first layer.

We focused on making the design as affordable and accessible as possible. It uses a Raspberry Pi computer and off-the-shelf electronic parts available online and at any hobby shop. Our hope is that school or university students will make their own ExoMy, to become familiar with robotics, and learn about the full-sized ExoMars rover, which is scheduled for launch in 2022,” said Swiss trainee Miro Voellmy.
