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.
Claims30
A water dispersible sulfo-polymer configured for use as a consumable feedstock in the additive manufacture of a part comprising a non water dispersible polymer, wherein the water dispersible sulfo-polymer is a reaction product of a sulfo monomer and the reaction product is at least on selected from the group consisting of a sulfo-polyamide, a sulfo-polyesteramide, and a sulfo-polyurethane with approximately 18 to 35% sulfoisophthalic monomer, 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.
2-3. (canceled)
5-6. (canceled)
The water dispersible polymer of claim 3 wherein the water dispersible polymer is characterized by a glass transition temperature of at least approximately 45 C.
14-20. (canceled)
A water dispersible sulfo polymer configured for use as a consumable material in the additive manufacture of a part comprising:
- a non water dispersible polymer, wherein the water dispersible polymer is a reaction product of a metal sulfo monomer selected from the group consisting of a sulfo-polyamide, a sulfo-polyesteramide, and a sulfo-polyurethane 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 polymer.
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 at least one selected from the group consisting of a sulfo-polyamide, a sulfo-polyesteramide, and a sulfo-polyurethane with approximately 18 to 35% sulfoisophthalic monomer.
