All three are explained in more detail in the bill, but arrive at broadly the same destination. This law, if approved, would prevent 3D printer brands from selling their wares in Washington State without stringent controls to prevent the printing of 3D firearms, or indeed parts that could be used to modify existing weapons.

According to the bill, violating this proposed law would be a class C felony, which means anyone found in violation of these terms could face up to five years in prison and a $15,000 fine.

Washington is not the first state to propose addressing 3D-printed firearms by way of legislation, and is unlikely to be the last. Earlier this month New York took steps to ban 3D-printed guns, proposing the mandating of 3D printer safeguards and cracking down on the sharing and possession of 3D files containing guns or gun components.
