Claim:
1. Rapid Production Apparatus for producing an object by sequentially forming thin layers of a photopolymer material one on top of the other responsive to data defining the object, the apparatus comprising: a shuttle comprising: a printing head block mounted ton the shuttle, the printing head block comprising: at least one printing head having a surface formed with at least one output orifice and controllable to dispense a photopolymer material in liquid form through the orifice; and a lamp mounted on the shuttle and laterally displaced from the at least one output orifice, said lamp controllable to provide radiation that polymerizes the photopolymer material, wherein the lamp comprises: a controller adapted to control the printing head to dispense the photopolymer material and sequentially form the layers and to control the lamp to irradiate and polymerize the dispensed photopolymer material; wherein a substantial portion of radiation provided by the lamp is directed so that it is incident at a substantially non-normal angle on the layers.
