Researchers Find Vulnerability In 3D Printing

A latest study by Indian-origin researchers have found vulnerabilities in 3D printers by examining two aspects — printing orientation and insertion of fine defects. The researchers found that since Computer-Aided Drafting (CAD) files used in the creation, modification, analysis, or optimization 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. The finding, along with...
