Abstract
An additively manufactured medical implant, comprising a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone, and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating.

9. An additively manufactured medical implant, comprising:
-
a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone; and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating; wherein the medical implant is produced from the steps of; imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone; removing a three-dimensional section from the design model; fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the design model; and using an additive manufacturing technique to create a physical implant including the fabricated porous region. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An additively manufactured medical implant, comprising:
-
a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone; and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating; wherein the medical implant is produced from the steps of; creating a digital image of the bone with a microCT scanner; removing any defective artifacts from the digital image; converting the digital image to a three-dimensional design model of the bone; removing a three-dimensional section that structurally replicates the architecture of the bone from the design model; printing the removed design model section on a digital representation of the implant; and creating a physical implant from the printed digital representation by using an additive manufacturing technique. - View Dependent Claims (19, 20, 21, 22)

23. An additively manufactured medical implant to fill a bone void, comprising:
-
a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone; and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating; wherein the medical implant is produced from the steps of; imaging a voided bone region with a high resolution digital scanner to generate a three dimensional design model of the voided bone region; providing a digital representation of a non-voided bone region; removing a three dimensional section of the non-voided bone region, the removed section having a size that substantially matches the size of the voided bone region; and creating a physical implant from the removed three dimensional section of the non-voided bone region by using an additive manufacturing technique, the implant being configured to be installed within the voided bone region.
