Abstract
An example of a three-dimensional printing kit includes a particulate build material including from about 80 wt % to 100 wt % metal particles based on a total weight of the particulate build material. The three-dimensional printing kit further includes a binder fluid including water and polymer particles in an amount ranging from about 1 wt % to about 40 wt % based on a total weight of the binder fluid. The polymer particles have from about 1% to about 10% of a phosphate functional group.
Claims9
A three-dimensional printing kit, comprising:
- a particulate build material including from 80 wt % to 100 wt % of metal particles based on a total weight of the particulate build material;
- and
- a binder fluid including water and polymer particles in an amount ranging from 1 wt % to 40 wt % based on a total weight of the binder fluid, the polymer particles having from 1% to 10% of a phosphate functional group,
- wherein the phosphate functional group is formed from a polymerized phosphate monomer selected from the group consisting of:
- a phosphate ester of a polyethylene glycol monomethacrylate;
- a phosphate ester of a polypropylene glycol monomethacrylate;
- and
- combinations thereof.

A method of three-dimensional printing, comprising:
- iteratively applying individual build material layers of a particulate build material which includes from 80 wt % to 100 wt % of metal particles based on a total weight of the particulate build material;
- based on a 3D object model, selectively applying a binder fluid to the individual build material layers to define individually patterned layers, the binder fluid including water and polymer particles in an amount ranging from 1 wt % to 40 wt % based on a total weight of the binder fluid, the polymer particles having from 1% to 10% of a phosphate functional group;
- and
- heating the individually patterned layers to form a 3D intermediate object,
- wherein the phosphate functional group of the polymer particles of the binder fluid is formed from a polymerized phosphate monomer selected from the group consisting of:
- a phosphate ester of a polyethylene glycol monomethacrylate;
- a phosphate ester of a polypropylene glycol monomethacrylate;
- and
- combinations thereof.
