    We present work in 3D printing electric motors from basic materials as the key to building a self-replicating machine to colonise the Moon. First we explore the nature of the biological realm to ascertain its essence particularly in relation to the origin of life when the inanimate became animate. We take an expansive view of this to ascertain parallels between the biological and the
