On 5 May 2013, Defense Distributed-a self-described "?private defense contractor in service of the general public"-released the data for an almost entirely 3D-printed firearm , christened the 'Liberator'. From that point onwards, 3D printing of firearms and firearm components began to proliferate. Today's designs, however, have advanced a long way from their progenitor of less than a decade earlier. The barriers to entry have been dramatically lowered, and emergent technologies such as electrochemical machining (ECM) and desktop/micro-CNC have paved the way for the average person to craft-produce, with a little perseverance, capable self-loading hybrid firearms such as the FGC-9. Individuals can increasingly obtain firearms without having to access criminal networks or legally controlled firearms distribution channels, maintaining anonymity and independence.It is highly likely that the FGC-9 is simply the first of a new wave of cheap, nearly-entirely-homemade 3D-printable firearm designs which solve material limitations by incorporating readily available metal components and unregulated firearms parts. This new breed of design offers adopters a cheap and effective firearm that is very difficult to trace, and may have the potential to rival or outstrip previous trends in the acquisition of illegal firearms modified from replica and deactivated firearms-themselves subject to increasing legislation. There are very limited control options for restricting access to the materials or design files used in craft-producing such weapons, and progressively more affordable machines and tools-as well as ongoing refinement of techniques-are likely to make their continued development and acquisition increasingly commonplace. As technical hurdles are raidly overcome, rifle-calibre firearms requiring strong locking actions-previously the preserve of factories-may soon be produced in the same low-tech manner as the FGC-9.
