A framework for assessing technical feasibility of additive manufacturing of an engineering design. This framework needs to be based on preliminary identification of key parameters that influence the decision making process. The parameters may also be customized for a particular application. Each of these parameters can be assigned weightage either relative or arrived at by paired comparison using a pre-determined minimum point method. Each of the attributes are then assigned scores which are then multiplied by the weightages assigned. The summation of all such scores on a weighted average basis indicates the potential for 3D printing of that part or assembly. It offers to select the right part to leverage the benefit of additive manufacturing. It narrows down on the ideal manufacturing process for the qualified parts and proposes to reduce subjectivity by using paired comparison of attributes. It also provides a faster assessment of technical aspects of the design.

Framework to assess technical feasibility of designs for additive manufacturing

A system and method for obtaining topologically optimized structure in additive manufacturing. A finite element mesh of a standard shape geometry encompassing desired structure to be optimized with a design objective and orthotropic properties of material arising out of a selected material and selected additive manufacturing process to be used for manufacturing. An iterative topology optimization is carried out wherein the process includes simulation of loading requirements, design constraints and the boundary condition. The performance evaluation process uses a finite element analysis framework to obtain the factor of safety between two consecutive iterations based on the anisotropic properties of the material. The process will achieve a minimal factor of safety and a best suitable build orientation of the design.
