1. A method of forming an intervertebral implant using additive layer manufacturing comprising:
alternately depositing and heating successive layers of a first source material to form a first portion of a body of the intervertebral implant;
alternately depositing and heating successive layers of a second source material subsequent to the formation of the first portion to form a fastener blocker; and
alternately depositing and heating successive layers of the first source material subsequent to the formation of the first portion to form a second portion of the body,
wherein the depositing and heating steps result in the fastener blocker being captured between the first and second portions such that a head of the fastener blocker is contained within the body, and
wherein the fastener blocker is configured to be moveable between a first position where the fastener blocker blocks at least part of an opening in the body and a second position where the fastener blocker does not block any part of the opening.
