Abstract: A print system and a method for curing marking material on an object using an active LED array in a three dimensional (3D) object printer are disclosed. For example, the print system includes a plurality of printheads, a curing light source comprising a plurality of light emitting diodes (LED) that are independently addressable, a movable member to hold an object, and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to control movement of the movable member and to operate each one of the plurality of LEDs of the curing light source to apply energy in accordance with a shape of the object to cure the marking material.

Abstract: A print system and a method for detecting inline failure of a curing light source of a 3D object printer are disclosed. For example, the print system includes a plurality of printheads, a curing light source, an inline failure detection (IFD) system, a movable member to hold an object, a heat resistant member coupled to the movable member that holds a thermal paper for testing operation of the curing light source and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to operate the curing light source to apply energy to the thermal paper and to cure the marking material, and to operate the IFD system to read the thermal paper to detect a failure of the curing light source.

Abstract: A print system and a method for curing marking material on an object using a mask screen are disclosed. For example, the print system includes a plurality of printheads, a curing light source, a movable member to hold an object, a mask screen and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to control movement of the movable member to catch the mask screen and to operate the curing light source to cure the marking material, wherein the amount of energy that is applied to the object is controlled by the mask screen.
