The 3DprintedClock project is the result of ready-assembled 3D printed computational mechanisms, and is related to research in the fields of rapid prototyping and digital fabrication. The clock was modeled in CAD software after an existing clock, and uses a weight and a pendulum to keep track of time. The CAD model was created according to the specifications of the 3D printer, assuring sufficient gaps and clearances for the different parts. In addition, support material, drainage, and perforations were added to allow for excess support material being removed after printing. The 3DprintedClock is intended to demonstrate the superior capabilities of 3D printing as a fabrication process. It should contribute toward the future use of 3D printers to replace injection molding and expensive tooling processes, and allow for on demand, customized, and �greener� consumer products.
