N2 - This study proposes a new path planning methodology to control functionally graded materials in hollowed scaffold printing for tissue engineering. Based on ruled surface construction from our earlier work [1], ruling lines are postprocessed for continuous path planning with uniform material deposition. Besides, arc fitting is used to reduce over-deposition by enabling non-stop deposition at the sharp turns. Layer-by-layer deposition is progressed through consecutive layers of ruling line based zigzag pattern followed by a biarc fitted spiral pattern. Functionally graded material properties are then mapped based on parametric distances from hollow features.
