Abstract: Methods of making fluorescent metallic toners are provided which comprise forming one or more fluorescent latexes which comprise a fluorescent agent, a first type of amorphous resin, and a second type of amorphous resin, wherein the first and second types of amorphous resins are present at a ratio in a range of from 2:3 to 3:2; forming a mixture comprising the one or more fluorescent latexes; a dispersion comprising aluminum flakes and a surfactant; one or more emulsions which comprise a crystalline resin, the first type of amorphous resin, the second type of amorphous resin; and optionally, a wax dispersion; aggregating the mixture to form particles of a predetermined size; forming a shell over the particles of the predetermined size to form core-shell particles; and coalescing the core-shell particles to form a fluorescent metallic toner. Fluorescent metallic toners and methods of using such toners are also provided.

Abstract: Compositions include polymer filaments compatible with fused filament fabrication, comprising: a thermoplastic polymer; and a bio-based additive admixed with the thermoplastic polymer in an effective amount to decrease total volatile organic compound (TVOC) emissions under additive manufacturing conditions, as determined by gas chromatography and measured relative to the thermoplastic polymer alone, by at least about 10% on a weight basis. Methods for forming a polymer filament compatible with fused filament fabrication may comprise: forming a melt blend comprising a thermoplastic polymer and a bio-based additive; and extruding the melt blend and cooling to form a polymer filament comprising the bio-based additive admixed with the thermoplastic polymer. The bio-based additive is present in an effective amount to decrease total volatile organic compound (TVOC) emissions under additive manufacturing conditions, as determined by gas chromatography and measured relative to the thermoplastic polymer alone, by at least about 10% on a weight basis.
