Abstract: According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution using a hot wire anemometer. Fountain solution thickness is measured using the flow rate of vaporized fountain solution and comparing to baseline air only flow rate. The vaporized measurement is correlated with the baseline utilizing specific heat, density and enthalpy values and keeping velocity of fluid constant. Changes in the measurement will then be related to the specific heat, density and enthalpy. Density can be back calculated to yield volume and knowing the area of the image being printed give a real time thickness value.

Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined from diagnostic images that are printed and analyzed using the existing Image Based Controls (IBC). An analysis of the density of solids, halftones, and background as a function of the fountain solution control parameter is performed to decide on the appropriate level of fountain solution. A latitude window of control parameters is then derived for which the digital offset lithography printing system in operation minimizes the undesirable effects of too much or too little fountain solution.

Abstract: A 3D printing system applies colored powders (e.g., primary colors, white, black, cyan, magenta, yellow, fluorescent colors, metallic) in printed polymer layers for forming a colored 3D object. The system may stabilize a powder layer or color sub-layers thereof, for example with one or more of heat, pressure, and/or high-intensity light. On each layer, powders of various colors may be sequentially deposited in a halftone pattern and stabilized, so as to create a part with a specified arrangement of colors throughout its structure. Benefits include more stable color than strategies involving jetting colored fluids. The arrangement of color on the interior of the part could provide functional or traceability benefits for specific applications. The examples allow for depositing a greater quantity of powder on each fiber base or substrate, decreasing the ratio of fiber to powder and increasing production speed.

Abstract: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may lead to excessive porosity following consolidation. Excessive porosity may be detrimental for performance applications requiring high mechanical strength. A carboxylic acid-based sintering aid, particularly a metal carboxylate, may decrease porosity of consolidated parts following sintering without substantially increasing blocking in a powder bed. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a carboxylic acid-based sintering aid admixed with a thermoplastic polymer, and a plurality of nanoparticles disposed upon an outer surface of the thermoplastic particulates.
