Abstract
A manufacturing method includes using an additive manufacturing process to form a first object. The first object includes layers, among which is a first layer that comprises a first material and a second material. The first material surrounds the second material within the first layer. Both materials are solids that transition into liquids at corresponding first and second temperatures, the first temperature being lower than the second temperature. The method includes, after having formed the first object, exposing the first object to a temperature that is between the first temperature and the second temperature such that the first material melts, thereby leaving behind a second object, the second object comprising the second material.
