Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away from the printed part, resulting in a part having surface cavities.

An illustrative method of making a fuel cell component includes obtaining at least one blank plate including graphite and a polymer; establishing a temperature of the blank that is sufficient to maintain the polymer in an at least partially molten state; and applying a compression molding force to the blank until the polymer is essentially solidified to form a plate including a plurality of channels on at least one side of the plate. The blank plate has a central area having a first thickness. The blank plate also has two generally parallel edges on opposite sides of the central area. The edges have a second thickness that is greater than the first thickness.

Ways to produce a container (315, 415, 515, 720, 815, 915) having a shaped tail (610, 910) are provided that include blow molding a precursor having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) and shaping the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) to form the shaped tail (610, 910). Various types of blow molding can employ various types of precursors having tails (510). Injection blow molding can be used where a preform (105, 200, 305, 405, 505) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is optionally longitudinally stretched and is expanded with a gas or a liquid. Extrusion blow molding can be used where a parison (705) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is expanded. A tail (105, 110, 205, 310, 410, 510, 715, 810, 910) shaping means can be part of the blow molding process or can be employed after the container (315, 415, 515, 720, 815, 915) is produced from the precursor having the tail (105, 110, 205, 310, 410, 510, 715, 810, 910). The shaped tail (610, 910) can impart functionality to the container (315, 415, 515, 720, 815, 915), including where the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is shaped into a coupling point that can serve as an attachment point, hanging point, or hook, for example.
