By using pareto diagram, research found three major problems that took the biggest roles: pieces that are not aligned with the rotary engine, pieces that are not aligned with the coak engine, and missing in the printing process. In the analysis process of the reduction of defective productions within the three major problems, there are six factors causing the defections: men, machines, methods, measurements, materials, and environments with men and machines as the biggest contributors.
