Abstract:
A printer compensates for printing errors occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates data corresponding to edges of each layer of the object after each layer is printed. Differences between the raster data used to eject the material to form a layer and the data received from the optical sensor are used to modify the raster data that operates a printhead to form a next layer in the object.
Abstract:
A process for creating adhesive signage for in-store shelving involves applying a PSA (pressure sensitive adhesive) tape to paper and then printing the signs on the modified substrate. The adhesive strips are 10 mils thick and the paper is 8 mils thick with the tape being positioned on a top portion only of the paper. This creates uneven stack issues in the feeder of the printer that prevents proper feeding of the sheets into the printer. These issues are eliminated by providing taped media imposition that orients the PSA to signage card color bands which are imposed in a mirror image. Mirror imaging of indicia on the card color bands evens out the sheet stack and enhances sheet feeding.
Abstract:
A three-dimensional object printer has a platen that is configured to facilitate the release of objects formed on the platen. The platen includes a first layer and second layer, the first layer having a coefficient of thermal expansion that is different than a coefficient of thermal expansion of the second layer. A controller in the printer is configured to operate at least one ejector in an ejector head to form a three-dimensional object on the surface of the platen with reference to digital image data and, upon completion of the object, to operate a temperature control device operatively connected to the platen to bend the platen by changing the temperature of the platen and releasing a three-dimensional object from the platen.
Abstract:
A variable guide system for shingling in-store adhesive signage cards that works with the offset moment/trajectory resulting from some shingling systems by employing multiple adjustable hold downs guides. Adjustments to the hold downs guides are made on the fly by an operator using easily accessible and controllable thumb screws. The thumb screws facilitate side to side movement and angle adjustment of each guide individually in order to prevent jamming of the cards while being shingled at the guides.

Abstract:
A three-dimensional object printer includes an actuator that contacts a surface of a platen in the printer. A controller selectively operates the actuator to apply force to a bottom layer of a three-dimensional object formed on the platen to break an adhesion between the bottom layer and the platen.
