1. A method of producing a three-dimensional porous tissue ingrowth structure comprising:

  • depositing a first layer of a metal powder onto a substrate;

    scanning a beam having a negative beam overlap at least once over at least a portion of the first layer of metal powder to remelt at least a portion of the metal powder in order to create at least two solid portions separated from one another so as to control porosity;

    depositing a second layer of the metal powder onto the first layer; and

    repeating the scanning steps for each successive layer until a desired height is reached.
