An article includes multiple layers of polyaryletherketone (PAEK), in which each layer is composed of a continuous length of PAEK, in which the continuous length of PAEK in at least one of the layers includes an interior portion, and an exterior surface including crystalline regions, in which a crystallinity of the exterior surface is higher than a crystallinity of the interior portion. The cross-sectional area of the continuous length of PAEK is non-uniform within each layer. Each layer defines a plane, and a portion of the continuous length of PAEK in each layer extends out of the plane defined by the layer. The multiple layers of PAEK define a network of interconnected pores.

Additively manufactured porous polymer medical implants

A system and method for forming a medical implant using a printing device. The printing device includes a print head having a heated nozzle, a heated build plate for receiving the printed material thereon, and a reflective plate having an active heater. A method for forming a medical device includes extruding a printing material by contiguous deposition to form a porous object having a lattice-like structure. The medical device, such as a spinal implant, may have interconnected pores and different regions, each having a different porosity for encouraging bone growth therein. The printed medical implant may be designed to be patient-specific, customized, and printed on-demand.
