Print Blocking is Anti-Consumer - Permission to Print Part 1

Proposals in three U.S. states would require commercial 3D-printer makers to limit printers to their own software and screen each print for gun-like shapes, and some bills would add criminal penalties for bypassing these limits. Print blocking is described as anti-consumer and a form of DRM-style lock-in, citing Bambu Labs' firmware update that complicated use of the open source OrcaSlicer until community backlash forced accommodations. The text also notes that ghost guns are often bought as kits rather than printed at home, and warns the blocking system could expand to items such as replacement parts.
