It seems like every month there is a new 3D printer on kickstarter and they all look the same to me. Good on them for having a go but I worry that a lot of people buying these "new" printers are new to the hobby and don't realise they could build themselves a Mendel Prusa for less than the cost of a lot of them on offer. It also irks me that there is little new in terms of 3D printing and the people raising the capital are effectively using open-source technology to line their pockets.
Kickstarter is well suited to small runs of printers by garage/cottage manufacturers and I'm guessing that your average venture-capitalist is going to be looking for something larger than a run of 100 printers so apart from the question of whether it is a genuinely "new" concept or design it is a very useful vehicle for funding small scale projects like ours.
