1. A method, comprising:
dispensing a powdered material to form a first layer of a powder bed on a support surface of a build platform for printing an object;
selectively fusing, based on a volume of the object being printed, a first portion of the powdered material in the first layer of the powder bed to form a first enclosure that contains within at least one part of the remaining unfused powdered material in the first layer of the powder bed on the build platform, the first enclosure staying in direct contact with the remaining unfused powdered material; and
printing the object on the build platform using the powdered material contained by the first enclosure.
