Indian-origin researchers report cybersecurity risks in 3D printing

A team comprising of Indian-origin researchers has found cybersecurity risks in 3D printing by examining two aspects — printing orientation and insertion of fine defects.

They found that since Computer-Aided Drafting (CAD) files — used in the creation, modification, analysis, or optimisation of a design — do not give instructions for printer head orientation, malefactors could alter the process without detection.

Also, sub-millimetre defects that can appear between printed layers with exposure to fatigue and the elements were found to be undetectable by common industrial monitoring techniques, the researchers said.
