3D printing (aka additive manufacturing) has the potential to transform the world by simplifying manufacturing, shortening supply and distribution chains, democratizing production, creating and repatriating jobs, and customizing products to our needs. But 3D printing can also be used for both causing crimes and solving them. This course provides details on 3D printed weapons, from the primitive single-shot “Liberator” made in 2013 to 3D printed grenade launchers. The course also covers 3D printed ammunition and accessories, such as suppressors, bump-fire stocks, and high-capacity magazines, and legislation relating to 3D printed weapons.

3D Printing 101 for Law Enforcement, Illegal Uses of 3D Printing, and 3D Printing as an aid to law enforcement are covered in depth in other courses and periodic updates.
