VOLUME ELEMENT (VOXEL) PRINTING SYSTEM FOR PRINTING A THREE-DIMENSIONAL OBJECT
First Claim
1. A volume element (voxel) printing system for printing a three-dimensional object, the system comprising:
- a first printhead group having a plurality of first printheads configured to print a first voxel layer on a substrate;
at least one second printhead group having a plurality of second printheads downstream from the first group, the second group configured to print a subsequent voxel layer on at least part of the first layer, said second printheads being reconfigurable as backup printheads for the first printheads in case of failure;
a conveyor to operatively convey the substrate past the printhead groups; and
a control system to control and monitor the printhead groups and the conveyor, and to dynamically reconfigure the second printheads if failure of a first printhead is detected.

Abstract
A volume element (voxel) printing system for printing a three-dimensional object is provided. The system includes a first printhead group, at least one second printhead group, a conveyor and a control system. The first printhead group includes a plurality of first printheads configured to print a first voxel layer on a substrate. The second printhead group includes a plurality of second printheads located downstream from the first group and configured for printing a subsequent voxel layer on at least part of the first layer. The second printheads are reconfigurable as backup printheads for the first printheads in case of failure. The conveyor is configured to operatively convey the substrate past the printhead groups. The control system controls and monitors the printhead groups and the conveyor, and is configured to dynamically reconfigure the second printheads if failure of a first printhead is detected.
