In his 2013, second term State of the Union address, President Obama mentioned 3Dprinting, that it "has the potential to revolutionize the way we make almosteverything." He mentioned the additive manufacturing hub the US government ishelping to fund in Youngstown Ohio and three more they are about to launch,suggesting Congress should "create a network of 15 of these hubs and guarantee thatthe next revolution in manufacturing is made in America."National Additive ManufacturingInnovation Institute (NAMII)

“A self-replicating machine is a construct that iscapable of autonomously manufacturing a copy of itselfusing raw materials taken from its environment”
RepRap takes the form of a freedesktop 3D printer capable of printingplastic objects. Since many parts ofRepRap are made from plastic andRepRap prints those parts, RepRapself-replicates by making a kit of itself -a kit that anyone can assemble giventime and materials.“RepRap is humanitys ﬁrst general-purpose self-replicating manufacturing machine”
