California Gov. Gavin Newsom signed a package of 10 new gun-control measures Saturday as the state continues adding restrictions on firearm ownership, sales and manufacturing.

One of the most notable measures is Assembly Bill 2047, known as the Firearm Printing Prevention Act. The law targets the use of consumer 3D printers to manufacture firearms and certain firearm components.

Under the new law, manufacturers of consumer 3D printers sold in California will be required to incorporate technology capable of identifying and blocking attempts to print firearms or prohibited firearm parts. State officials and gun-control advocates have described the measure as an effort to address the growing availability of 3D-printed firearms, commonly referred to as ghost guns.

Another measure, Senate Bill 948, expands California's Firearm Safety Certificate requirements. Beginning in 2029, prospective gun owners will be required to complete a minimum four-hour training course that includes live-fire exercises and classroom instruction prescribed by the state.

The package also includes Assembly Bill 1743, which expands access to information contained in California's Automated Firearms System and related firearm databases.

Senate Bill 1220 creates a new misdemeanor that triggers a 10-year prohibition on firearm possession under California law. The measure adds another category of offense to the state's list of crimes that can result in a temporary loss of firearm rights.

Newsom's office said the legislation addresses multiple areas of California's firearm regulations, including firearm storage, training, prohibited possession, reporting, and emerging firearm technology. The governor's office described California as the nation's leading state for gun-law strength and effectiveness.

The legislation has received support from gun-control organizations including Everytown for Gun Safety, which called the 3D-printer law a significant step toward preventing the production of untraceable firearms.

The new laws will add to California's already extensive firearms regulations as state lawmakers continue targeting both traditional firearm sales and newer technologies that can be used to manufacture guns outside the conventional firearms industry.
