Extrusion width refers to the width of the material line deposited by a 3D printer’s nozzle during the printing process. In cybersecurity contexts, extrusion width may be discussed in relation to hardware security for 3D printers, as incorrect settings can lead to defects or vulnerabilities in printed components. Understanding and controlling extrusion width is important for ensuring the structural integrity and security of 3D-printed objects, especially when producing parts for secure systems or devices.
