Harris County Joins National Effort
Harris County District Attorney Sean Teare has joined prosecutors and law enforcement leaders from across the country in calling on leading consumer 3D printer manufacturers to implement safeguards that would prevent their machines from being used to produce illegal firearms and firearm components.
The request comes as law enforcement agencies report a sharp rise in the recovery of so-called “ghost guns,” privately manufactured firearms that do not carry serial numbers and are significantly more difficult to trace during criminal investigations.
In a joint letter organized by Prosecutors Against Gun Violence, prosecutors asked three of the world’s largest consumer 3D printer manufacturers, Creality, Bambu Lab, and Flashforge, to develop technology capable of recognizing and blocking the printing of firearms and key firearm components.
“Technology shouldn’t give dangerous individuals a shortcut to dodge background checks, build untraceable guns, or undermine public safety,” Teare said. “As 3D printing becomes more widespread, manufacturers must adopt commonsense safeguards to curb this type of weapon production, and lawmakers need to step up and act.”
Why Prosecutors Are Concerned
The coalition argues that advancements in consumer-grade 3D printing have made it easier for prohibited individuals, including convicted felons and people barred from possessing firearms because of domestic violence convictions or protective orders, to manufacture firearms outside of the traditional regulatory system. Prosecutors also expressed concern that some 3D-printed firearm components could present additional security challenges in locations such as courthouses and airports.
Houston has already seen cases involving 3D-printed firearms. Authorities noted that in 2022, a suspect charged with shooting three Houston police officers allegedly used firearm components produced with a 3D printer. More recently, an 18-year-old in El Paso was arrested after authorities say he fired a 3D-printed handgun within city limits. Similar investigations involving ghost guns, machine gun conversion devices, and illegal firearm manufacturing have also been reported in states including California, Kentucky, Louisiana, and New York.
According to Everytown for Gun Safety, recoveries of 3D-printed firearms have increased by nearly 1,000 percent across 20 major U.S. cities over the past five years.
The prosecutors’ letter also points to recent legislative action in New York, where a new law requires consumer 3D printers sold in the state to include safeguards designed to prevent the printing of firearms and firearm components. Similar legislation is currently being considered in California and Washington.
Rather than waiting for additional state-by-state legislation, the coalition is encouraging manufacturers to voluntarily adopt similar safety standards nationwide. Prosecutors have also requested meetings with company representatives to discuss potential technological solutions that balance innovation with public safety.
As 3D printing technology becomes more affordable and accessible, officials say the conversation is shifting beyond innovation alone to include how manufacturers, lawmakers, and law enforcement can work together to address emerging public safety concerns surrounding untraceable firearms.
