Engineers should use a step in the design of any physical object selecting the material which makes them design cost-effective part features with regard to the tool size required to produce them.
Any physical object's design process includes selecting a material. Minimizing costs while attaining performance goals for the product is the main purpose of material selection in the context of product design. A rigorous process of selecting the best material for a certain application begins with evaluating the characteristics and prices of prospective materials.
When choosing materials, it can often be helpful to use a material index or performance index related to the desired material qualities. As an illustration, a thermal blanket's thermal conductivity must be low to minimize heat transfer for a particular temperature difference. As a result, choosing the material for any physical thing should be a stage in the design process for engineers.
