  • We present a novel process to fabricate three-dimensional (3D) metallic patterns from 3D printed polymeric structures utilizing different hygroscopic swelling behavior of two different polymeric materials. 3D patterns are printed with two different polymers as cube shape. The surface of the 3D printed polymeric structures is plated with nickel by an electroless plating method. The nickel patterns on the surface of the 3D printed cube shape structure are formed by removing sacrificial layers using the difference in the rate of hygroscopic swelling between two printing polymer materials. The hygroscopic behavior on the interfaced structure was modeled with COMSOL Multiphysics. The surface and electrical properties of the fabricated three-dimensional patterns were analyzed and characterized.

  • This paper deals with the development of mechatronics fusion curriculum in Handong Global University. The execution of the program, which has been more than ten years long, is presented in the paper. The research indicates that changing the double major program from mechanical and metal engineering to mechanical and electronics control engineering resulted in dramatically increased number of students in the program and increased number of employment opportunities for graduating students. Percentage of satisfaction on the double major program was the highest from students enrolled among ten double major programs in the school. Overall grade average was significantly improved in junior year students compared to sophomore year students indicating the students became more engaged in their studies after having been trained in the program for one year. It is believed that multiple hands-on experiments and class projects conducted throughout the course assisted the development of the new curriculum. The study shows that the mechatronics fusion program is promising since it is relevant to the need of current age of industrial field that demands engineers with multidisciplinary capability.
