Title (EN) FUSING AGENT INCLUDING A TETRAPHENYLDIAMINE-BASED DYE
(FR) AGENT DE FUSION COMPRENANT UN COLORANT À BASE DE TÉTRAPHÉNYLDIAMINE
Abstract:
(EN) An example of a fusing agent includes a tetraphenyldiamine-based dye, alkyldiphenyloxide disulfonate, 1-methyl-2-pyrrolidone, and a balance of water. The fusing agent excludes a strong reducing species. The fusing agent may be incorporated into a three-dimensional printing method or a three-dimensional printing system. In an example of the three-dimensional printing method, a polymeric or polymeric composite build material is applied. The fusing agent is selectively applied on at least a portion of the polymeric or polymeric composite build material. The polymeric or polymeric composite build material is exposed to electromagnetic radiation to fuse the portion of the polymeric or polymeric composite build material in contact with the fusing agent to form a layer.
(FR) Selon un exemple, l'invention concerne un agent de fusion comprenant un colorant à base de tétraphényldiamine, un disulfonate d'alkyldiphényloxyde, une 1-méthyl-2-pyrrolidone et le reste d'eau. L'agent de fusion exclut une espèce à réduction forte. L'agent de fusion peut être incorporé dans un procédé d'impression en trois dimensions ou dans un système d'impression en trois dimensions. Selon un procédé d’impression tridimensionnelle cité à titre d'exemple, un matériau de construction polymère ou composite polymère est appliqué. L'agent de fusion est appliqué sélectivement sur au moins une partie du matériau de construction polymère ou composite polymère. Le matériau de construction polymère ou composite polymère est exposé à un rayonnement électromagnétique pour faire fondre la partie du matériau de construction polymère ou composite polymère en contact avec l'agent de fusion afin de former une couche.
