Abstract
A multi-step method of making a mammalian subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period includes depositing at least portions of one or more individual layers of the implant by at least one computer controlled 3-D printer. The 3-D printing method may be accomplished via an array of 3-D nozzles that deposit materials (such as plastics, thermoplastics, coating materials, drug-containing matrix materials, non-drug containing matrix materials, bonding materials, biodegradable materials and/or the like) in very small, precise portions. The materials may be deposited in liquid, powder, sheet or other forms. Non-implant forms may also be provided by the techniques disclosed herein.
