Official summary
Abstract published by the legislature (via Open States). Text as published by the legislature; reproduced verbatim.
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.)
