Design scalability is a technique used in routine design and manufacturing to adapt existing design knowledge to varying requirements. Guidelines exist for design scalability for subtractive manufacturing but there is much less support for components produced through additive manufacturing process. Due to particularities of additive manufacturing many process parameters related to additive manufacturing need to be taken into account while designing the parts with an expected functional requirement. The objective of the investigation described in this paper is to evaluate the effect of using design scalability technique for the 3D printed components with a focus on mechanical properties of the design. This is done through identifying and aggregating a list of comprehensive process parameters from research and available 3D printing machines, and then developing a standard based Taguchi s design of experiment to analyse the effect of these parameters, including scalability on the mechanical properties of an ISO compliant test sample for ultimate tensile stress and Elastic Modulus. A list of optimised parameters is also presented for achieving high tensile properties in 3D printed components.
