The satellite was developed by students at the Tomsk Polytechnic University to test new space materials technology and is the world’s first space vehicle with a 3D-printed structure. It was launched from Baikonur in Kazakhstan to the ISS on March 31, 2016 in a Progress-MS-2 cargo vessel.

It will be deployed by hand during a Russian spacewalk, which is why unlike other CubeSats this one has a handle. The call sign of the satellite is RS4S.

According to Alexey Yakovlev, head of the Tomsk Polytechnic University’s Institute of High Technologies, the 3D printed satellite is something of a landmark for additive manufacturing, being the first example of a fully 3D printed satellite: “The Tomsk-TPU-120 is the first such project in the world, in which the entire casing of a satellite is fully 3D printed using dynamic modeling,” Yakovlev recently told Sputnik. “The combination of these technologies can significantly reduce the development time and the number of full-scale tests, find new engineering solutions, and reduce the project’s cost.”

In May 2016 the Tomsk Polytechnic University celebrated its 120th anniversary. As part of the celebrations on May 10/11 the Tomsk-TPU-120 was activated in the ISS and transmitted a greeting to Earth inhabitants, recorded by students of the university in 10 languages: Russian, English, German, French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.

The greeting message was transmitted once a minute on 437.025 MHz FM. A Kenwood transceiver on the ISS provided a cross-band relay, re-transmitting the signal on 145.800 MHz FM.
