Washington State May Mandate 'Firearm Blueprint Detection Algorithms' For 3D Printers

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) writes: Washington State lawmakers are proposing bills (HB 2320 and HB 2321) that would require 3D printers and CNC machines to block certain designs using software-based "firearms blueprint detection algorithms." In practice, this means scanning every print file, comparing it against a government-maintained database, and preventing "skilled users" from bypassing the system. Supporters frame this as a response to untraceable "ghost guns," but even federal prosecutors admit the tools involved are ordinary manufacturing equipment. Critics warn the language is overbroad, technically unworkable, hostile to open source, and likely to push printing toward cloud-locked, subscription-based systems-while doing little to stop criminals.
