Abstract: Composite formulations useful in the production of objects by the solid freeform fabrication method comprise (A) an epoxidized drying oil (primary resin); (B) a curing agent; (C) a fibrous filler; (D) a thixotropic agent and optionally (E) a secondary resin. These composites are characterized by unique physical properties including enhanced biodegradability.

Abstract: The present invention relates to biomedical implants for bone substitution and replacement applications. The implant includes a strong, porous polymeric or thermoplastic compositions and growth-enhancing compositions.

Abstract: In a rapid prototyping system, a part is formed by depositing a bead of slurry that has a sufficient high concentration of particles to be pseudoplastic and almost no organic binders. After deposition the bead is heated to drive off sufficient liquid to cause the bead to become dilatant.

Abstract: This invention encompasses porous, nanocrystalline, biomimetic calcium phosphate coatings of the order of 2-30 microns that can be grown on metal implants. The chemical surface treatments and methods for making the calcium phosphate coatings are disclosed. Post treatment with dilute hydrogels such as phema reinforce the inorganic structure and enhance the mechanical strength of the coatings. Methods are also disclosed for adsorbing or covalently attaching growth factor proteins to derivatives of the hydrogel coated calcium phosphate coatings. Such hydrogel reinforced calcium phosphate coatings show equivalent bone tissue growth as the currently used implants and are easily resorbed. This property in combination with the immobilized growth factors is expected to enhance the process of osseointegration of the disclosed coatings.
