PRINT HEAD ASSEMBLY FOR EXTRUSION-BASED ADDITIVE CONSTRUCTION
A print head assembly, for use in extrusion-based additive construction is disclosed. The print head may be optionally equipped with a fluid channel for aiding in the regulation of the temperature of the print head cold end, and one or more thermal monitors for monitoring the temperature of the cold end of the print head.
1 . A print head, for use in extrusion-based additive construction, comprising:
a cold end having a front end, a rear end, a left side, a right side, a top surface extending from the front end to the rear end and from the left side to the right side and a bottom surface extending from the front end to the rear end and from the left side to the right side
wherein the print head is equipped with a temperature sensor, the temperature sensor being configured to monitor a temperature of the cold end; and
a hot end configured to provide a melt zone, the hot end being attached to the cold end.
2 . The print head of claim 1 , wherein the temperature sensor is located proximately to the print head.
3 . The print head of claim 1 , wherein the temperature sensor is embedded in the print head.
4 . The print head of claim 1 ,
wherein the left side has a first timing belt attachment slot extending substantially from the front end to the rear end, and
wherein the right side has a second timing belt attachment slot extending substantially from the front end to the rear end.
5 . A print head, for use in extrusion-based additive construction, comprising:
a cold end having a front end, a rear end, a left side, a right side, a top surface extending from the front end to the rear end and from the left side to the right side and a bottom surface extending from the front end to the rear end and from the left side to the right side;
a hot end configured to provide a melt zone; and
a heat break attached to the hot end and the cold end,
wherein the print head is equipped with a temperature sensor, the temperature sensor being configured to monitor a temperature of the heat break.
6 . The print head of claim 5 , wherein the temperature sensor is located proximately to the cold end.
7 . The print head of claim 5 , wherein the temperature sensor is embedded in the cold end.
8 . The print head of claim 5 ,
wherein the left side has a first timing belt attachment slot extending substantially from the front end to the rear end, and
wherein the right side has a second timing belt attachment slot extending substantially from the front end to the rear end.
