Discussion:  3D printing recently produced its first patient-specific human jaw.  The jaw was made out of titanium powder which was heated and fused together by a laser one layer at a time.  The implant involves articulated joints, cavities to promote muscle attachment and grooves to direct the regrowth of nerves and veins.
