Laser-produced porous surface |
摘要 |
The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant. |

1. A method of producing a three-dimensional porous structure comprising:
depositing a first layer of a metal powder onto a substrate; scanning a beam at least once over the first layer of metal powder to remelt the metal powder in order to create at least two solid portions separated from one another so as to give a required pore size; depositing a second layer of metal powder onto the first layer; and repeating the scanning steps for each successive layer until a desired height is reached. |
