DENVER — Coloradans will no longer be able to make 3D-printed guns and agricultural workers will have to work 56 hours in a week before they qualify for overtime under a pair of bills signed into law by Gov. Jared Polis on Monday.

House Bill 1144, the ban on 3D-printed guns, goes into effect July 1. The law expands on Colorado’s prior ban on firearms without serial numbers, known as “ghost guns,” by prohibiting the use of 3D printers or computerized milling machines to manufacture firearms or components like large-capacity magazines and rapid-fire trigger activators.

Polis had threatened to veto an earlier version of the bill that included a prohibition on selling or distributing “digital instructions” needed to print the firearms or their components. Sponsors stripped that measure out before it reached his desk.

Senate Bill 121 increases the overtime threshold for some agriculture workers from 48 hours to 56 hours outside of the peak harvest times. The measure passed narrowly— and with more Republican than Democratic votes — in each chamber of the legislature. Democrats hold a nearly two-to-one majority in each chamber.

Those new overtime provisions go into effect in Jan. 1, 2027. Proponents of the measure argued it’s necessary for a struggling and vital industry and that it would help workers because they could be scheduled for more hours. Opponents argued that bill — voted on weeks after lawmakers renamed a holiday for farmworkers— would mean more exploitation of an already economically vulnerable population.

Polis also signed House Bill 1058 on Monday. That measure seeks to protect children used in online content creation by requiring the content creators to set aside a portion of proceeds until the child reaches adulthood and allow adults or emancipated minors who were used in content as children to have that content deleted upon request, among other protections.
