There must be plenty of ‘broken’ 3d printers sitting around collecting dust. In this video, we examine if an experienced user, with plenty of knowledge and spare parts, could buy these printers, fix them and profit from their sale. My experience shows that while there may be some easy conversions, sometimes you’ll take a loss on a difficult machine, and that puts a question mark over the whole idea.
