Researchers report cybersecurity risks in 3-D printing — ScienceDaily

Researchers examined two aspects of additive manufacturing (AM), or 3-D printing, that could have cybersecurity implications and harmful economic impact: printing orientation and insertion of fine defects. They found that because CAD files do not give instructions for printer head orientation, malefactors could deliberately alter the process without detection. Also, sub-millimeter defects that can appear between printed layers with exposure to fatigue and the elements were found to be undetectable by industrial monitoring techniques.
