DESCRIPTION
Cape Canaveral (askanews) – Successful launch on December 7 from the space station NASA in Cape Canaveral for the shuttle Cygnus freighter carrying 3 tons of supplies to the men on board the International Space Station. a mission that speaks Italian very well; not only does the pressurized module of the shuttle was built in Italy, in the plants of Thales Alenia Space in Turin, but Italian is also the most important load of the Swan: the Portable Printer on Board 3D, the 3D printer designed to work in microgravity , made by Altran and Thales AS with coordination of the Italian Space Agency (ASI) .So spoke, to askanews, Costantino Volpe, project manager of the experiment. “Print 3D objects in general – he said – is a ‘ utility linked to the flexibility of the process and form. Print ISS is the possibility of not carry tools and spare parts but to manufacture them only on need “. The objective, therefore, is to create spare parts and tools directly in space, so as to reduce the cost of future space missions. “These – continued Volpe – are some of the examples of the molds that we performed as preliminary tests. The forms are the most diverse, with a rather limited volume of about 10 cm square. As we calibrated the printing parameters to arrive at a higher accuracy. This for example could be the elbow of a pipe that could replace parts unaparte realistically “. Basically, if something were to break or if there was a need to have a special tool, the control center on Earth could just send email a file that the system is built directly into orbit. “The organic plastic – said Fox – it is heated to 180 degrees and extruded shapes composing 2D, so succession plans in 2D. The 3D object is the composition of many prints 2D “. The printing of 3D objects could have technological implications in the biomedical field. This is also why, after being in orbit, the printer will return to Earth for analysis post-flight experiment.
