1. An additive manufacturing apparatus for forming an object by steering an energy beam onto powder layers to selectively consolidate areas of each layer, the apparatus comprising:
a build chamber;
an elevator movable in the build chamber, the elevator being arranged such that a build substrate can be releasably secured thereto; and
a powder dispenser configured to deposit successive layers of the powder onto an upper surface of the build substrate as the build substrate is lowered by the elevator, wherein
the build substrate is releasably securable to the elevator via a fastener, the fastener being accessible for releasing the substrate from the elevator from a side surface of the build substrate that is between the upper surface and a lower surface of the build substrate.
