Abstract: A method includes controlling an additive manufacturing system to fabricate a 3D structure using successive layers of material. The additive manufacturing system includes a build platform having a first region, second region, and overlapping third region between the first and second regions; and multiple sources configured to build (e.g., deposit, bond, melt, solidify) the successive layers of material in the regions of the build platform. Controlling the additive manufacturing system includes controlling the additive manufacturing system to build first, second, and third portions of the 3D structure within the regions of the build platform. Each portion of the 3D structure includes (i) one or more test features that are common to the portions of the 3D structure and (ii) a substrate onto or into which the one or more common test features are formed.

Abstract: An additive manufacturing obstacle part can comprise a base structure comprising at least one external obstacle, and at least one internal obstacle that is formed at least partially within the base structure. The at least one internal obstacle can comprise an elongated internal obstacle extending through the base structure between an inlet and an outlet formed in the base structure. The elongated internal obstacle can comprise at least one wall extending along a nonlinear path. The non-linear path can hinder travel of excess material from an additive manufacturing process along a linear path between the inlet and outlet. This can help a designer to assess an additive manufacturers ability to cleanly produce an internal feature to specifications while removing excess material resulting from the additive manufacturing process.
