Abstract
A carriageless print head assembly, for use in extrusion-based additive construction is disclosed. The carriageless print head features a cold end equipped with one or more timing belt attachment slots and bores for receiving bearings to achieve linear motion. The carriageless print head may be optionally equipped with some combination of an air conduit for cooling the top layer of the constructed product, a fluid channel for aiding in the regulation of the temperature of the print head cold end, and a thermal monitor for monitoring the temperature of the cold end of the print head. A computer-mediated method of monitoring the cold end of the print head to limit jams due to overheating is also disclosed.
Claims9
A method of performing extrusion-based additive construction using a 3D printer equipped with a print head and a controller, the print head comprising a hot end, a cold end, and a thermal monitor, the thermal monitor comprising a temperature sensor, the method comprising the steps of:
- a. beginning, by the 3D printer, an extrusion-based additive construction;
- b. reading, by the temperature sensor, an operating temperature of the cold end;
- c. assessing, by the controller, whether the operating temperature is above a predetermined temperature threshold;
- d. pausing, by the controller, the construction for a predetermined amount of time and allowing the cold end to cool.
