Abstract
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.
