Additive manufacturing is a process to fabricate three-dimensional (3D) objects usually by joining a material layer by layer. The layer by layer joining process simplifies the fabrication method by slicing the 3D object into stacks of 2D contours. The layers are combined in a single build direction to form the 3D object. The purpose of this research is generate new knowledge in additive manufacturing process by integrate a six degree of freedom robot arm platform with a fused deposition modeling system entitled MotoMaker for additive manufacturing applications. The development of a higher degree of freedom additive manufacturing platform allows for multi-plane layering to be achieved in the same print. Use of the system offers unique advantages over a conventional additive manufacturing platform which is limited to single-plane layering for the printing of 3D objects. This dissertation examines the capabilities of the multi-plane motion platform for additive manufacturing applications. Exploration of the capabilities of the MotoMaker platform for multi-plane printing technique to print a 3D object was conducted. The capabilities of this robot arm platform for additive manufacturing applications was explored through various multi-plane and 3D lattice structure printing techniques to build 3D objects. Mechanical characteristic of the printed objects was performed to determined the effect of multi-plane printing on printed part mechanical properties. An algorithm to generated a toolpath for the multi-plane printing platform was developed. The advantages of the multi-plane printing technique include the capability to print a 3D object with overhang structure without support material. Additionally, a 3D lattice structure was able to be printed based on the geometric features of the lattice using the multi-plane printing technique. Furthermore, the multi-plane printing technique is capable to enhanced the mechanical properties of the printed part.
