TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE
The present invention relates to a toner for development of electrostatic images which contains a colorant, a resin composition (P) and a resin composition (W), in which the resin composition (P) is a resin composition formed by subjecting an acid group-containing amorphous polyester-based resin (A) and an amine compound to condensation reaction, and the resin composition (W) is a resin composition formed by subjecting an alcohol component (W-al), a carboxylic acid component (W-ac) and a hydrocarbon wax containing at least one functional group selected from the group consisting of a hydroxy group and a carboxy group to condensation reaction; and a process for producing the toner.
Semi-crystalline consumable materials for electrophotography-based additive manufacturing system
A part material for printing three-dimensional parts with an electrophotography-based additive manufacturing system, the part material including a composition having a semi-crystalline thermoplastic material and a charge control agent. The part material is provided in a powder form having a controlled particle size, and is configured for use in the electrophotography-based additive manufacturing system having a layer transfusion assembly for printing the three-dimensional parts in a layer-by-layer manner.
WATER DISPERSIBLE POLYMER FOR USE IN ADDITIVE MANUFACTURING
A water dispersible sulfo-polyamide is configured as a filament for use as an extrudable support material in the additive manufacture of a part comprising a non water dispersible polymer. The water dispersible sulfo-polyamide is a reaction product of a sulfo monomer, the water dispersible sulfo-polymer being dispersible in water resulting in separation of the water dispersible polymer from the part comprising the non water dispersible polymer.
Water dispersible polymer for use in additive manufacturing
A water dispersible sulfopolymer for use as a material in the layer-wise additive manufacture of a 3D part made of a non water dispersible polymer wherein the water dispersible polymer is a reaction product of a metal sulfo monomer, the water dispersible sulfo-polymer being dispersible in water resulting in separation of the water dispersible polymer from the 3D part made of the non water dispersible polymer.

Recycling and reuse of sulfonated polymer material in additive manufacturing
A method of recycling and reusing a tap water-soluble sulfonated polymer material from a structural component made using an additive manufacturing process comprises dissolving the structural component in water to disperse the sulfonated polymer material into the water. The sulfonated polymer material is precipitated from the water and recovered; then dried and reformed into a form suitable for subsequent use as a consumable feedstock in a subsequent additive manufacturing process.
