Israeli concept artist Eyal Gever designed a digital representation of human laughter and this structure will be 3D printed on the International Space Station (ISS).
Made in Space developed an FFF 3D printer that allows for 3D printing in zero gravity. Gravity isn’t the only thing that lacks in space. In space there is no air, so in space there are no sound waves to transport sounds.
The artist thought about what kind of shouting sounds or language he can visualise to be printed, when a friend told him that the one universal understandable sound is laughter.
