NASA engineers digi rds Budinoff Jason (Jason Budinoff) develops the first full-featured digi rds 50-millimeter mini-camera space, a kind of mini-telescope collected from almost 3D-parts. The size of the camera allows digi rds you to use it for Cubesat digi rds - small (midget) artificial satellites for space exploration, which have a volume of 1000 cubic centimeters and a weight of not more than 1.33 pounds.
The device will be made from the body and mountings for the optical sight that will be printed as a single structural element in a special 3D-printer, and also have mirrors and glass lenses made in the traditional way.
Manufacturing technology of 3D-parts, which are used NASA, different from conventional printing techniques on 3D-printer. In contrast to the conventional three-dimensional printer that pushes the flow of molten plastic, NASA printer with a laser, computer-controlled, melts in the right place aluminum powder, titanium, or other metal.
Budinoff wanted to show that the use of 3D-printer may be very advantageous, because small telescope digi rds construction require fewer components, which in this case will have a small value, digi rds compared with the number of components digi rds manufactured in the usual manner.
"Telescopes for scientific devices usually includes hundreds of items. Because these components are difficult to manufacture, digi rds they are expensive. But with the help of 3D-printing, we can reduce the total number of items and make them almost arbitrary shape "- said Jason Budinoff.
Completion of the project is expected at the end of September, after which the camera will take a thermal vacuum testing and vibration testing, according to the website digi rds NASA. The project is financed program of internal R & D Goddard (IRAD).
