3D Printing Legislation Tracker https://maxsikorski.github.io/3d-printing-regulation/ Updates from the 3D Printing Weekly meetup's community tracker of 3D printer and 3D-printed firearm legislation. en-us Thu, 01 Oct 2026 12:00:00 -0400 AB 2047 is law: signed Sep 26, dormant until ASTM acts https://maxsikorski.github.io/3d-printing-regulation/#ca-ab2047 3dpl-2026-10-01-a Thu, 01 Oct 2026 12:00:00 -0400 Governor Newsom signed AB 2047 on Sep 26 (Chapter 461, Statutes of 2026). It takes effect Jan 1, 2027, but the printer sale ban only starts if ASTM International publishes a blocking-tech standard and the CA DOJ writes rules: mid-2028 at the very earliest, realistically 2030 or later, possibly never. The card now covers owners, used sales, gifts, self-built machines and businesses. Take Action has a new "Get in before the standard exists" panel, and the letter generator now writes to the CA DOJ. AB 2047 presented to Governor Newsom — decision by Sep 30 https://maxsikorski.github.io/3d-printing-regulation/#ca-ab2047 3dpl-2026-09-17-a Thu, 17 Sep 2026 12:00:00 -0400 AB 2047 was formally enrolled and presented to Governor Newsom on Sep 14 at 1:30 p.m. He must act by Sep 30: sign, veto, or the bill becomes law without his signature — California has no pocket veto. The card's timeline, details, and verification date are updated. New: the Prop Problem tab, and what ASTM actually is https://maxsikorski.github.io/3d-printing-regulation/#prop-problem 3dpl-2026-09-03-b Thu, 03 Sep 2026 12:00:00 -0400 The Prop Problem now has its own tab — why shape-detection algorithms and Star Wars prop blasters can't coexist, with examples from our own members' testing. The Blocking Technology tab gains a plain-language explainer of ASTM International, the standards body California's AB 2047 hangs on. Tracker launched — AB 2047 is on Newsom's desk https://maxsikorski.github.io/3d-printing-regulation/ 3dpl-2026-09-03-a Thu, 03 Sep 2026 10:00:00 -0400 The tracker goes live with 12 cards: California AB 2047 (passed the legislature Aug 31, 60-18 concurrence; Governor Newsom signs or vetoes by end of September), New York's signed blocking-tech law, Washington's HB 2320 (in force) and stalled HB 2321, New Jersey's file-possession law, Colorado HB26-1144, the serialization wave, the US federal baseline, and the UK, Australia, Canada, and EU.
