it is orbiting a 3D printer the whole Italian
The project is funded by the Italian Space with Altran and Italian Institute of Technology in Turin. The device is able to build solid objects on the Space Station will be used for interplanetary travel and long stays away from the Earth
The Portable On-orbit Printer-3D
“the astronauts traveling to Mars in the future and will retain a long time on the moon will have the need for on-site objects various types. Our 3D printer is now on the Space Station. It works perfectly. ” Piero Messidoro, is Chief Technical Officer of Thales Alenia Space Italy, the same who along with Orbital ATK builds modules Cygnus PCM matched to their propulsion system. Another Cygnus cargo module (the fifth in the series) is ready to take the leap into space: the launch is scheduled for April, always with a carrier rocket Atlas 5 of the United Launch Alliance. The last sent into orbit last December 3, housed aboard several tons of materials, and for the first time it was launched in the long version, with three sections instead of two.
It was aboard a technological apparatus that looks to the future of space missions; a 3D printer, called “Portable On-orbit Printer-3D”, for the first time held in Europe for the practical use of the astronauts, already a few weeks ago they tested on the International Space Station: “It is a project funded by ‘ Italian Space agency – explains Piero Messidoro – that we made together with Altran and the Italian Institute of Technology in Turin. It is an apparatus able to build solid objects on the Space Station, through thermoplastic polymeric material. Media, containers or any other object is useful for certain types of maintenance, will be achievable by means of such apparatus in a short time. ”
But what good is a 3D printer in space travel? “It’s unthinkable in the future, for long interplanetary voyages carrying everything; we are thinking of apparatus able to realize other types of objects useful for the life of the astronauts edge. We think about what happened on Apollo 13 – reminds Messidoro – when the astronauts had to build the Air Filters with makeshift material. In this case, however, in case of need, it will be possible to realize the exact object for maintenance. Just send by e-mail a CAD drawing of the part and the machine it will be able to realize. ”
The other technological innovation is precisely the Cygnus modules, starting at 9:10 units, on which you are working to set up with a new and innovative technique: “The segments of the pressurized module and the propulsion module will be merged with friction welding – adds Messidoro – and thus without the addition of additional material. With a weld of this type it is to amalgamate the plasticity conditions can reached the two parts without other materials. With a significant gain in terms of mass and of process efficiency and a saving of time and costs. ”
The Cygnus that last December led the 3D printer all made in Italy, and tons of other materials, was the fourth operational, and resumed flights after the failure of the carrier Antares in October 2014: ” We are working to number 9 modules and 10, while the 6, 7 and 8 have already been completed for some time, but we look over the new contract for CRS modules 2 – confirms the engineer of Thales Alenia Space Italy – We have increased the capacity to load with the three segments up to 3,500 kilograms, compared to the 2,700 originally planned. ” The propulsion system Orbital / ATK of Cygnus is similar to that achieved for ESA on the ATV cargo modules, the amended version will be the service module for Orion, the new US spaceship to space exploration.
