Abstract
A method of forming a chemical delivery device with an active chemical includes generating halftoned image data using a stochastic halftone screen a concentration parameter for the active chemical. The method also includes ejecting a chemical carrier including the active chemical into a portion of a plurality of cavities formed in the chemical delivery device using the halftoned image data to produce the chemical delivery device with a concentration of the active chemical corresponding to the concentration parameter.
Claims9
A method of producing a chemical delivery device with a three-dimensional object printer comprising:
- receiving with a controller a first concentration parameter for a first active chemical in a first region of a substrate in the chemical delivery device;
- generating with the controller halftoned image data using a stochastic halftone screen and with reference to the first concentration parameter, the halftoned image data including a plurality of activated pixels that correspond only to locations of a first portion of a plurality of cavities formed in a substrate that receive the first active chemical;
- and
- ejecting with at least a first ejector a predetermined amount of a first chemical carrier including the first active chemical into each cavity in the first portion of the cavities in the substrate with reference to the halftoned image data to produce the chemical delivery device with a concentration of the first active chemical corresponding to the first concentration parameter.
