ABSTRACT:
A three-dimensional object creation system is provided. The system comprises: (i) a first printhead layer group comprising a plurality of first printheads configured for printing a first layer of the object; (ii) a second printhead layer group comprising a plurality of second printheads configured for printing a second layer on the first layer, the second layer group being downstream of the first layer group; (iii) a conveyor for conveying a partially-formed object past the layer groups; (iv) a fault-detection system for detecting a malfunctioning layer group; and (iv) a control system for dynamically reconfiguring at least one second printhead to print at least part of the first layer in the event that the first layer group is malfunctioning.
