Abstract: A three-dimensional (3D) printer material cartridge for a 3D printer includes an indicator disposed on an exterior surface of the 3D printer material cartridge. The indicator colorant is responsive to energy from an energy source of the 3D printer. The indicator is a message that becomes visible in response to exposure of the colorant to the energy.

Abstract: A three-dimensional (3D) printer includes a cartridge receiver to receive a material cartridge containing new material for generation of a 3D object. The 3D printer also includes an energy source disposed to expose an indicator on the material cartridge to energy in response to depletion of the new material in the material cartridge to change the appearance of the indicator. The changed appearance of the indicator indicates that the material cartridge no longer contains new material.
