David from EEVblog designed a FDM/FFF 3D printer from ground up.
Its main purpose is prototyping and like a regular printer it is supposed to be put on a shelf. The project is David´s Capstone, that is something like his thesis. He designed everything completely from the ground up – from the controller and the software that runs on the controller to the chassis and the print bed, which is based on a Sarrus linkage. The bed has hinges on all four sides, so it only needs one motor to control the height and always stays levelled.

Unfortunately there are no plans to commercialise the rPrint at this time.
