Abstract: According to examples, an apparatus may include a build platform and a chamber. The chamber may support a layer forming station including a spreading component to spread a layer of build material particles onto the build platform and an agent delivery component to apply fusing agent onto selected locations on the spread layer of build material particles and a heating station including a heating component to apply energy onto the spread layer of build material particles and the applied fusing agent, in which the heating station is separated from the layer forming station. The apparatus may also include an actuator to move the chamber with respect to the build platform or vice versa while maintaining the separation between the layer forming station and the heating station.
