An apparatus, system and method for printing an object with a rapid prototyping machine (RPM) working in a computer network environment including one or more rapid prototyping RPMs, enables users in different locations to add objects to a virtual construction platform that is being prepared for printing via the computer network. Available space on the virtual construction platform for building the object may be communicated and instructions to add the model to the available space may be communicated via the network.

Rapid prototyping apparatus

Apparatus for producing a three-dimensional model by sequentially forming layers of photopolymer material one on top of the other responsive to data defining the three-dimensional model is disclosed. The apparatus includes at least one printing head configured to dispense the photopolymer material, an array of LEDs controllable to provide radiation to polymerize the photopolymer material and a controller. The controller is configured to control the at least one printing head to dispense the photopolymer material to sequentially form the layers of material. The controller is also configured to turn on the array of LEDs to provide the radiation to cure the photopolymer material when situated above the model and to turn off the array of LEDs when not situated above the model.

Apparatus for producing an object by sequentially forming thin layers of a construction material one on top of the other responsive to data defining the object, the apparatus comprising: a plurality of printing heads each having a surface formed with a plurality of output orifices and controllable to dispense the construction material through each orifice independently of the other orifices; a shuttle to which the printing heads are mounted; a support surface; and a controller adapted to control the shuttle to move back and forth over the support surface and as the shuttle moves to control the printing heads to dispense the construction material through each of their respective orifices responsive to the data to form a first layer on the support surface and thereafter, sequentially the other layers; wherein each printing head is dismountable from the shuttle and replaceable independently of the other printing heads.
