There is currently a bill in the NY State Assembly to require background checks for the purchase of 3D printers - eviltoast
NY State Assembly Bill 2025-A2228
www.nysenate.gov
Requires a criminal history background check for the purchase of a three-dimensional printer capable of creating firearms; prohibits sale to a person who would be disqualified on the basis of criminal history from being granted a license to possess a firearm.

Technically it’s for any printer capable of printing a firearm or the components of a firearm, which is…. every printer. What a bafflingly stupid proposal. If you’re in NY, please call your reps and tell them to oppose this bill.
