Abstract
A method of additive manufacturing of un-vulcanized rubber includes providing a printing apparatus and providing un-vulcanized rubber to the printing apparatus. The method also includes warming the un-vulcanized rubber and pressurizing the un-vulcanized rubber provided to the printing apparatus to a pressure of at least 800 psi. The method further includes positioning a dispenser at a beginning of a series of motion control commands, dispensing the un-vulcanized rubber from the printing apparatus onto an area, and cutting the dispensed un-vulcanized rubber.
