 In 2012, the first successful Delta design, Rostock, had a radically different design.The latest iterations used OpenBeams, wires (typically Dyneema or Spectra fishing lines) instead of belts, and so forth, which also represented some of the latest trends in RepRaps.In early January 2016, RepRapPro (short for "RepRap Professional", and one commercial arm of the RepRap project in the UK) announced that it would cease trading on 15 January 2016.
