Abstract
Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform
Claims19
An additive manufacturing 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;
- directing a two-dimensional patterned energy beam toward the powder bed;
- and
- selectively fusing a portion of the powdered material in the first layer of the powder bed to form (i) one or more first walls out of the fused portion of the first layer of the powder bed such that the one or more first walls serve as variable print chamber walls to contain the printed object and a unfused portion of the first layer of the powder bed on the build platform, and (ii) a fluid passageway in the one or more first walls that is connected to a source of a fluid.
