Abstract: A method, of manufacturing a series of objects is disclosed. In the method, a layer of a manufacturing medium is provided. Portions of the layer of the medium, are bond together at at least edge regions of the layer to form a support portion. The support portion is lowered while gripping the support portion by the edge regions of the layer. A further layer of the medium is provided supported by the support portion. Portions of the further layer of the medium are selectively bound to form at least an object portion. An apparatus for performing the method is also disclosed.

Abstract: An additive manufacturing process comprising adding a support to an object model to create a modified object model f an object with a support to be built. The support extends from an object end coupled to the object to a distal end to be engaged with a carrier to support the object. A build model is created by arranging the modified object model within a virtual build volume with the distal end of the support at a defined location within the virtual build volume. Instructions are then provided to build a build cake corresponding to the build model, the build cake comprising the object with support and non-solidified build material.

Abstract: An in-process build assembly includes an in-process build structure, a support structure, and semi-sintered particles. The support structure supports the in-process build structure. The support structure surrounds a cross-section of the in-process build structure without surrounding an entirety of the in-process build structure. The semi-sintered particles are located between the in-process build structure and the support structure such that there is no direct attachment of the in-process build structure to the support structure. The in-process build assembly is fabricated by an additive manufacturing process. Either one of or both the in-process build structure and the support structure are moved after the additive manufacturing process such that the cross-section of the in-process build structure is outside the support structure.
