Indonesia is known as one of the largest pulp and paper manufacturers in the world. However, it still relies too heavily on technology from foreign countries. In relation to the Government’s policy to support import substitution, the use of domestic goods should be increased including in this sector. Therefore, the inverse of engineering design or reverse engineering technique should be implemented in an effort to manufacture the disc refiner in the local industry. This technique is a long process that started by identifying the existing product then choosing the suitable manufacturing method and finally generate the same product or even the enhanced version. This paper will present how to build the 3D model of the pulp disc refiner using 3D-scanner and CAD software as the essential step in reverse engineering technique. In addition, it will also provide the material composition of the disc refiner for the preparation to manufacture the improved product. The result of this research can be used as guidance for the local machinery manufacturers to strengthen their competitiveness, especially in manufacturing the machines for pulp and paper industries. Keywords: 3D model, disc refiner, reverse engineering, manufacture, import substitution.
