AB 2047 Downgrades 3D Printer Mandate from Skilled-User Evasion Block to Likelihood Reduction Standard

The Assembly approved AB 2047 with amendments that removed criminal penalties for private resale and added narrow open-source and commercial carveouts. Language shifted from blocking technically skilled evasion to merely reducing foreseeable attempts, while third-party standards and manufacturer self-certification replaced prior testing mandates. These changes confirm the bill no longer claims technical efficacy against determined users.

The bill exempts Hollywood studios and compliant open-source tools yet burdens non-commercial developers with ambiguous blocking requirements. This pattern mirrors earlier expansions of digital controls into physical domains, such as state-level CNC router restrictions and DMCA anti-circumvention rules applied to manufacturing hardware. Data from 3D-printed firearm cases show existing serial-number and licensing statutes already cover unlicensed production without device-level mandates.

Commercial carveouts create tiered product lines that raise prices for non-exempt users while leaving indie fabricators and researchers exposed. No amendment resolves the infinite circumvention surface of G-code modification or firmware alteration. The bill now heads to the Senate with implementation delegated to non-governmental parties.

Senate committees will review the revised text before a floor vote. Primary enforcement falls on resellers required to verify software presence at point of sale.
