Once a revolutionary manufacturing innovation, 3D printing has become a double-edged sword. While the technology is driving progress across sectors like medicine and aerospace, it’s also being exploited to produce untraceable, homemade firearms.

In this episode, host Lucas Webber is joined by Yannick Veilleux-Lepage, Assistant Professor at the Royal Military College of Canada and a leading expert on the intersection of terrorism and emerging technologies. Together, they explore how 3D-printed weapons are being used by extremist actors, how online communities are spreading firearm blueprints, and why policymakers are struggling to respond to this growing security challenge.
