Separating element production in additive manufacturing

An additive manufacturing system comprising:

• a build material supply mechanism to deposit layers of build material on a build platform;
• a solidifying system to selectively solidify regions of build material to:
• produce a plurality of objects;
• and
• produce a separating structure forming an array of compartments, each said compartment containing a respective object of the plurality of objects,
• wherein the separating structure provides a barrier between the plurality of objects during subsequent application of gas to cool the plurality of objects.

A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to control an additive manufacturing system to, during an additive manufacturing operation:

• produce, by additive manufacturing comprising depositing layers of build material:
• a gas flow regulator;
• and
• a plurality of objects and a separating structure, wherein the separating structure forms an array of compartments such that each object of the plurality of objects is within a respective compartment of the array, and
• apply gas to unsolidified build material and to the plurality of objects, within said compartments to fluidize the unsolidified build material and thereby cool the plurality of objects, wherein the separating structure acts as a barrier between fluidized build material in respective compartments.
