Abstract
A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.
Claims20
A method of fabricating a medical implant comprising the steps of:
- successively depositing layers of a material and at least partially melting at least a portion of each deposited layer of the material at predetermined locations to form a first porous portion of the implant surrounding perimeters of both a first solid section of the implant and a second solid section of the implant spaced from the first solid section.
A method of fabricating a medical implant comprising the steps of:
- successively depositing layers of a material and at least partially melting at least a portion of each deposited layer of the material at predetermined locations to form a first porous portion of the implant surrounding perimeters of both a first solid section of the implant and a second solid section of the implant spaced from the first solid section,
- wherein the implant is porous between the first solid section and the second solid section, and
- wherein the first porous portion includes irregularly shaped pores.

- wherein the steps of successively depositing layers of a material and at least partially melting at least a portion of each deposited layer of the material at predetermined locations further forms a second porous portion of the implant between the first solid section and the second solid section,
- wherein the first porous portion includes irregularly shaped pores.
