Abstract
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.

A water dispersible sulfo-polymer configured for use as a consumable feedstock in an additive manufacture of a part comprising a non water dispersible polyamide based polymer having a glass transition temperature ranging from 185° C. and 225° C., wherein the water dispersible sulfo-polymer is a reaction product of a sulfo monomer and the reaction product is a sulfo-polyamide with approximately 18 to 35% sulfoisophthalic monomer wherein the water dispersible sulfo-polymer has a glass transition temperature within ±20° C. of the glass transition temperature of the non water dispersible polyamide based polymer, the water dispersible sulfo-polymer being dispersible in water resulting in separation of the water dispersible polymer from the three-dimensional part comprising the non water dispersible polymer, wherein the consumable feedstock comprises a filament form or a powder having a charge control agent.
A water dispersible sulfo polymer configured for use as a consumable material in an additive manufacture of a non water dispersible polyamide based polymer part comprising:
- a non water dispersible polyamide based polymer, wherein the water dispersible polymer is a reaction product of a metal sulfo monomer, the reaction product is a sulfo-polyamide with approximately 18 to 35% sulfoisophthalic monomer, the water dispersible sulfopolymer being dispersible in water resulting in separation of the water dispersible polymer from the part comprising the non water dispersible polyamide based polymer, wherein the non water dispersible polyamide based polymer has a glass transition temperature ranging from 185° C. and 225° C. and the water dispersible sulfo polymer has a glass transition temperature of ±20° C. of the glass transition temperature of the non water dispersible polyamide based polymer, wherein the consumable feedstock comprises a filament form or a powder having a charge control agent.
A consumable feedstock material for use in an additive manufacturing system, the consumable feedstock material comprising:
- a water dispersible sulfo polymer comprising a reaction product of a sulfur monomer and the reaction product is a sulfo-polyamide with approximately 18 to 35% sulfoisophthalic monomer, wherein the consumable feedstock comprises a filament form or a powder having a charge control agent wherein the water dispersible sulfo polymer has a glass transition temperature within ±20° C. of the glass transition temperature of a non water soluble polyamide based part material having a glass transition temperature ranging from 185° C. and 225° C.
