Abstract
Systems and methods for printing a luminescent 3-dimensional object. The method includes mixing a dry cementitious composition with water, the dry cementitious composition comprising a cementitious binder, conveying the mixture to a print head, applying the mixture and one or more luminescent compounds from the print head to form a luminescent 3-dimensional object, and curing the luminescent 3-dimensional object.

A method of printing a luminescent 3-dimensional object, the method comprising:
- mixing a dry cementitious composition with water, the dry cementitious composition comprising a cementitious binder;
- conveying the mixture to a print head;
- applying the mixture and one or more luminescent compounds from the print head to form a luminescent 3-dimensional object;
- and
- curing the luminescent 3-dimensional object.
A dry cementitious composition comprising, relative to a total dry weight of the composition:
- to 40 wt % of cement;
- 3 to 7 wt % of at least one of calcium aluminate cement and calcium sulfoaluminate cement;
- 0 to 35 wt % of at least one of slag and calcined clay;
- 4 to 12 wt % of one or more luminescent compounds;
- to 60 wt % of at least one of aggregates and fillers;
- and
- 1 to 2 wt % of further additives.
A system for printing a luminescent 3-dimensional object, the system comprising:
- a mixing device configured to mix a dry cementitious composition with water, the dry cementitious composition comprising a cementitious binder;
- and
- a conveyor configured to convey the mixture to a print head, the print head being configured to apply the mixture and one or more luminescent compounds from the print head to form a luminescent 3-dimensional object.
