Abstract: An exemplary embodiment provides a method of manufacturing a curved porous component having a base material layer and a porous region through one-step laminated-molding, whereby it is possible to reduce a manufacturing time when manufacturing a product and to provide a porous component in which the shape and size of a porous region can be controlled. An implant including the porous component has an increased bone contact ratio, so bone growth between bones can be improved and products fitting to the frames of patients can be easily designed.

Abstract: This application relates to a nickel-based superalloy suitable for additive manufacturing and a method for manufacturing a high-temperature member using the same. The nickel-based superalloy includes 13.7% to 14.3% by weight of Cr, 9.0% to 10.0% by weight of Co, 3.7% to 4.3% by weight of Mo, 2.6% to 3.4% by weight of Ti, 3.7% to 4.3% by weight of W, 2.6% to 3.4% by weight of Al, 0.15% to 0.19% by weight of C, greater than 0% by weight and not less than 0.005% by weight of B, 0.01% to 0.05% by weight of Zr, 2.0% to 2.7% by weight of Ta, 0.6% to 1.1% by weight of Hf, Ni residue, and unavoidable impurities. The nickel-based superalloy has a high fraction of strengthening phase, thereby maintaining excellent high-temperature strength. Additive manufacturing with the nick-based superalloy is much easier than existing nickel-based superalloys, thereby cost-effectively providing maximized cooling efficiency.
