Abstract
An example system includes an inlet, a guide structure, a heat exchange device and an outlet. In that example the heat exchange device is in thermal contact with the guide structure to change the temperature of print material. The print material may act on the temperature of a print head die while guided through the print head die.
Claims13
A system comprising:
- an inlet to provide a print material having a first temperature from a supply container;
- a guide structure coupled to the inlet to guide the print material to a print head die;
- a heat exchange device in thermal contact with the guide structure to controllably change temperature of the print material to a second temperature within a defined temperature range, while the print material is in the guide structure;
- and
- an outlet coupled to the guide structure to provide the print material to the print head die,
- wherein the print material is to act on a temperature of the print head die based on the second temperature and while guided through the print head die.
