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.
Claims15
A three-dimensional printing kit, comprising:
- a particulate build material including from about 80 wt % to 100 wt % 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 about 1 wt % to about 40 wt % based on a total weight of the binder fluid, the polymer particles having from about 1% to about 10% of a phosphate functional group.
A binder fluid for three-dimensional printing, comprising:
- 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 having from about 1 to about 10% of a phosphate functional group.
A method of three-dimensional printing, comprising:
- iteratively applying individual build material layers of a particulate build material which includes from about 80 wt % to 100 wt % metal particles based on a total weight of the particulate build material;
- based on a 3D object model, selectively applying water and polymer particles having from about 1% to about 10% of a phosphate functional group to individual build material layers to define individually patterned layers;
- and
- heating the individually patterned layers to form a 3D intermediate object.
