There are a growing number of laser-cut Rep(St)raps being developed. The (St) is in brackets because, as soon as we put a laser on one of these (which we have every intention of doing), they all immediately convert from being RepStraps to being RepRaps.
[Bits from Bytes] Ian Adkins of the company Bits from Bytes designed a lasercut version of Darwin, which you can either buy from them or make for yourself. This design has formed the basis of most of the laser-cut RepRap Darwin designs. Follow that link to go to the company's site.
