Embodiment 1

[0082] Pure titanium particles were stacked in layers, and a base material layer was formed by irradiating laser light at a scanning speed of 0.5 m / s and a light source power of 200 W. Laser irradiation spots having a diameter of 70 μm were formed on the substrate layer by gravure printing the first porous layer while adjusting the column distance and the spot distance by 350 μm each while irradiating laser light. The second porous layer was formed by layering pure titanium particles again on the first porous layer and adjusting the column distance and spot distance by 350 μm each while irradiating laser light to form laser irradiation spots with a diameter of 70 μm.

Embodiment 2

[0084] Pure titanium particles were stacked in layers, and a base material layer was formed by irradiating laser light at a scanning speed of 0.5 m / s and a light source power of 200 W. The first porous layer was embossed by layering pure titanium particles on the substrate layer and adjusting the column distance and spot distance by 350 μm each while irradiating laser light to form laser irradiation spots with a diameter of 70 μm on the substrate layer. The second porous layer was formed by layering pure titanium particles again on the first porous layer and adjusting the column distance and spot distance by 350 μm each while irradiating laser light to form laser irradiation spots with a diameter of 70 μm.

[0085] Table 1 below shows laser irradiation conditions at the time of forming the first porous layer and the second porous layer in Examples 1 and 2.

Abstract

An exemplary embodiment provides a method of manufacturing a porous component having a base material layer and a porous layer through one-step laminated-molding, whereby it is possible to provide a manufacturing time when manufacturing a product and to provide a porous component in which the shape and size of a porous layer 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.

Description

technical field [0001] The present invention relates to a one-step manufacturing method of a laminated porous part, more particularly, to a method of manufacturing a porous part having a substrate layer and a porous layer in one step using the lamination technique, and relates to a method for enlarging an implant. Manufacturing process of porous components with bone contact ratio. Background technique [0002] An implant is a material that reconstructs shape or replaces function by implanting artificial or natural materials into lost parts to compensate for the loss of biological tissue. In general, in dentistry or orthopedics, implants refer to biomaterials that replace human hard tissues, and research related to dental implants has been actively conducted since the mid-1960s. [0003] Metal materials with high strength, high hardness and low biotoxicity are selected as implant materials. Especially titanium and titanium alloys, as materials with excellent biocompatibilit...
