1. An apparatus for forming a specified object, the apparatus comprising:
a bed to receive a succession of layers of a build material;
a liquid functional material (LFM) dispenser to selectively dispense LFM on each layer of the build material in accordance with a cross-section of the object to be formed;
a supply of LFM for the LFM dispenser, wherein the LFM is not a binder that binds the build material, the LFM facilitating binding of the build material under an application of energy; and
a carrier to receive the succession of unbound build material layers comprising selectively placed LFM.
