A Russian 3D printer has created quite a stir as scientists from Tomsk Polytechnic University in Siberia have created the world's first satellite developed with the help of a 3D printer.
The Tomsk-TPU-120 satellite
Earlier this year, the Tomsk-TPU-120 satellite was delivered to the International Space Station (ISS); there, it is due to be placed into orbit in 2017. In an exclusive interview with Sputnik Brazil, Alexey Yakovlev, head of the Tomsk Polytechnic University's Institute of High Technologies, touted the Tomsk-TPU-120 as the world's first satellite developed with the help of a 3D printer.
He explained that dynamic modeling, along with 3D printing, allow developers to reduce the satellite's weight, give it strong characteristics and resist vibration.
"The current project is just the first stage of a long-term project to develop and create small, multi-purpose satellites. In particular, this work pertains to the creation of an on-orbit group of satellites dealing with many urgent problems related to agriculture, forest fires, climate change and natural resources," he said. Yakovled said that the Tomsk-TPU-120 satellite will be put into orbit in July, a process that he said would be implemented during the ISS crew's spacewalk. According to him, it will be Russian cosmonauts who will launch the satellite from the outer surface of the ISS, something that Yakovlev described as "a tricky and expensive procedure, preceded by repair or the modernization of the space outpost."
"Experiments with the satellite were conducted not only on board the ISS, but also on the ground. Many radio amateurs from all across the world were able to catch a satellite signal on their radio stations, and posted videos of it on the Internet," he said. Yakovlev added that after being put into orbit, the Tomsk-TPU-120 will be in free flight mode for about six months.
During this time, he said, its orbit will ebb gradually and it is slated to eventually enter the dense layers of the atmosphere, where it will be destroyed. He also said that in November 2016, the Russian Federal Space Agency Roscomos approved experiments on creating CubeSat satellites on board the ISS with the help of a 3D printer and then placing them into orbit. A CubeSat is a type of miniaturized satellite for space research that has a mass of no more than 1.33 kilograms per unit.
