3-D printer

A Palestinian-Canadian doctor has created a low-cost stethoscope using a 3-D printer, the first in a series of inventions he hopes will help alleviate medical supply shortages caused by an eight-year blockade on the Gaza Strip

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with NASA to design, build and test the 3-D printer.
