Fig. 3. Overview of the optimization algorithm used to find optimal 3D printing material formulations.

(A) The information needed for input that are the variables within the design space, design space constraints, performance objectives the algorithm is trying to attain, and an initial set of data that is used by the algorithm to build an initial model. (B) An overview of the iterative steps taken by the algorithm to suggest new formulations that may have higher performance. (C) The output from the algorithm after it has finished optimization.
