The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles of footwear containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.

Methods relating to the printing of materials using hybrid ink formulations are generally described.

Methods for the printing of materials using hybrid ink formulations

A flux composition is provided, comprising, as an initial component: a carboxylic acid; and, a fluxing agent represented by formula I: wherein R, R, Rand Rare independently selected from a hydrogen, a substituted Calkyl group, an unsubstituted Calkyl group, a substituted Carylalkyl group and an unsubstituted Carylalkyl group; and wherein zero to three of R, R, Rand Ris(are) a hydrogen. Also provided is a method of soldering an electrical contact using the flux composition.

Flux composition and method of soldering

A flux composition is provided, comprising, as initial components: a carboxylic acid; and, a polyamine fluxing agent represented by formula I: with the proviso that when the polyamine fluxing agent represented by formula I is according to formula Ia: then zero to three of R, R, Rand Ris(are) a hydrogen. Also provided is a method of soldering an electrical contact using the flux composition.

Polyamine, carboxylic acid flux composition and method of soldering

A flux composition is provided, comprising, as initial components: a carboxylic acid; and, an amine fluxing agent represented by formula I:  Also provided is a method of soldering an electrical contact using the flux composition.

Amine, carboxylic acid flux composition and method of soldering

A curable flux composition is provided, comprising, as initial components: a resin component having at least two oxirane groups per molecule; a carboxylic acid; and, an amine fluxing agent represented by formula I: and, optionally, a curing agent. Also provided is a method of soldering an electrical contact using the curable flux composition.

Curable amine, carboxylic acid flux composition and method of soldering

A curable flux composition is provided, comprising, as initial components: a resin component having at least two oxirane groups per molecule; a carboxylic acid; a fluxing agent represented by formula I: wherein R, R, Rand Rare independently selected from a hydrogen, a substituted Calkyl group, an unsubstituted Calkyl group, a substituted Carylalkyl group and an unsubstituted Carylalkyl group; and wherein zero to three of R, R, Rand Ris(are) a hydrogen; and, optionally, a curing agent. Also provided is a method of soldering an electrical contact using the curable flux composition.
