1. An article comprising:
multiple layers of polyaryletherketone (PAEK), in which each layer is composed of a continuous strand of PAEK, in which the continuous strand of PAEK in at least one of the layers comprises:
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;
in which the cross-sectional area of the continuous strand of PAEK is non-uniform within each layer, and
in which the multiple layers of PAEK define a network of interconnected pores.
