The number of engineering materials is increasing, and the product development cycle becomes shorter. At the same time, the requirements for product design become wider because the consumers are interested in the environmental aspect and aesthetic aspect as well as functional aspect. Under this circumstance, engineering designers should consider the multi-dimensional aspects for product design at the same time. However, there are few tools for multi-dimensional design method. Most design methods can support optimization of one dimension or provide information of each dimension. In this research, multi-dimensional design method was studied for engineering material selection. Material information contains material property, environmental impact, and cost. All numerical values of multi-dimensional information were demonstrated with graphical approach and the order of preferable materials was suggested.
