nasa urged to accelerate 3d printing on space station

A new report urges NASA to move quickly to study 3D printing on the international space station, which may have only 6 to 10 years of operational life left.
Praise NASA\'s efforts and focus on-
Space Manufacturing-
For example, a 3D printeris plans to launch a space station next month. the U. S.
National Research Council (NRC)
The report stressed that the agency should organize its centres to identify priority items for use at stations.
\"The international space station will not exist forever. this is where we can really do it [in-space]
Robert Latif, a retired American. S.
Major General of Air Force with doctoral degreeD.
In metallurgical engineering and materials science, tell space. com.
Latiff chaired the committee preparing the NRC report, which was released on July 18. [

Latiff says it makes sense to have humans supervise the process in the current state of development of 3D printing to ensure it meets the standards.
He added that this could pose a challenge for well-planned astronauts.
\"They measured the time to one minute,\" Latif said . \".
But the report notes that the space station offers a great opportunity to learn more about how 3D printing works in a weightless environment.
If the process is carried out outside the space station, it will teach researchers how to withstand thermal stress
For example, a rapid change from heat to cold
Material may be affected.
The United States recently proposed to extend the ISS operations until 2024 from 2020, but the request has not yet been approved by all other partners of the project.
Nowadays, there is not a lot of hype around 3D printers, and many news reports say these machines can produce lighter, stronger and more advanced parts than those made using traditional manufacturing techniques.
For example, Latiff said that it is possible for a single component to have different properties along its length, or to assemble components that do not have traditional connectors together.
However, the application of 3D printing in space requires a strong understanding of material science to make it work.
Latif said NASA has been experimenting in this area since the space lab space station in the 1970 s.
He urged scientists and manufacturers to strengthen integration as they seek other uses of 3D technology.
According to the report, 3D printing is still in its infancy, especially in manufacturing \"thinking\" materials such as semiconductors.
Today\'s printing focuses more on the manufacture of \"original\" electronic products such as prefabricated components and conductors.
\"You can build a part, but it\'s not entirely clear that 3D-
The parts made will definitely be as good [as a part]
It was built in other ways, \"said Latif.
\"Some of the things we talk about in the report, like certification, we haven\'t even started to understand.
\"Printing on the space station for a year is not the only thing to be considered.
The European Space Agency says 3D printing of lunar base components, such as human habitats, will be carried out one day.
NASA has also funded a company called infinite tether, which wants to launch very small materials (
Such as line axis)
Will become kilometers-
Long Sky lines or solar arrays in space.
In the United States, the Air Force plans to use 3D printing technology on the ground to make lighter components for rockets and satellites to reduce the amount of fuel needed to send objects into space.
But Mr. Latif said most of the Air Force\'s experience so far has focused on the aerospace sector, not on space components.
The report urged the Air Force and NASA to strengthen communication and share expertise.
Members of the committee spent more than a year studying the state of the industry, and then published their report called \"3D Printing in Space \".
\"Four or five meetings were held, most of which were open to the public, experts from NASA, Air Force, the Bureau of advanced research projects for national defense (DARPA)
And other participating organizations
Members of the committee include experts from the United States. S.
Laboratories, universities and military institutions.
One of the members, Sandy Magnus, was a former space shuttle and space station astronaut.
Latif said that the report was reviewed by a second committee of experts, in which the committee noted comments that had to be dealt with prior to publication.
