Recent advances in additive manufacturing have led to renewed interest in Functionally Graded Materials (FGMs) by enabling a wide variety of gradient paths via the layer-by-layer selection of composition. Despite these advances in capability, the occurrence of undesirable (ex. brittle) phases often complicate the manufacturing process. To address these concerns, others have suggested using CALculation of PHAse Diagram (CALPHAD) software to plan FGM gradient paths around these phases, but such works have been limited to linear paths planned manually using isothermal examinations of ternary systems. In this work, an algorithm is presented that can plan the gradient path of a one-dimensional FGM (composition change in only one spatial dimension) that avoids undesirable phases at a range of temperatures as predicted by CALPHAD software. The proposed algorithm employs motion planning techniques from the robotics community and is capable of planning nearly any shape of path for an arbitrary number of elements.
