Official summary

The act defines 3-dimensional printing to mean additive and subtractive manufacturing. The act prohibits knowingly manufacturing or producing a potentially functioning firearm, unfinished frame or receiver, large-capacity magazine, or rapid-fire device (firearm or firearm component) by 3-dimensional printing. The prohibition does not apply to a federally licensed firearm manufacturer, an instructor or student of an accredited gunsmithing program, or an institution that operates an accredited gunsmithing program. Unlawful 3-dimensional printing of a firearm or firearm component is a class 1 misdemeanor; except that a second or subsequent offense is a class 5 felony. The prohibitions in the act only apply to potentially functional firearms and firearm components. (Note: This summary applies to this bill as enacted.)

What it covers: the record exactly as the official source publishes it — its identifiers (bill number, session, jurisdiction), its official title and long title, its official summary, its status, its sponsors in published order, every recorded action, every recorded vote, and the link to each official text version — assembled in a fixed canonical form described on the How this data works page.
The fingerprint does not cover our retrieval date (the “Data as of” stamp in the source line): re-fetching unchanged official content produces the same fingerprint, while any change to the official content changes it.
If you recompute the fingerprint from the official source and get a different value, one of us is out of date — please report it through the corrections log.
