1. An apparatus comprising:
a build platform;
a chamber housing the build platform, wherein the chamber includes:
a curved top surface located above the build platform and carrying a layer forming station and a heating station, and
a pivot member located at a bottom of the chamber, below the build platform, wherein when the pivot member is rotated, the curved top surface of the chamber rotates in accordance with the pivot member to sequentially move each of the layer forming station and the heating station to a position directly above the build platform,
wherein the layer forming station includes a spreading component to spread a layer of build material particles onto the build platform and an agent delivery component to deposit fusing agent onto selected locations on the spread layer of build material particles; and the heating station includes a heating component to apply energy onto the spread layer of build material particles on which the fusing agent has been deposited; and
an actuator to rotate the pivot member of the chamber to cause each of the layer forming station and the heating station in the curved top surface to sequentially be positioned directly above the build platform.
