Apparatus, system and method of providing a FFF printing nozzle
View Patent ↗An apparatus, system and method for providing a nozzle having refined print control and enhanced printing speed by providing, on the inside or outside or on an interstitial substrate layer, of any metallic or non-metallic nozzle of a non-conductive surface suitable to support sensors relevant to the FFF process. Heat, force, flow, strain, stress, extrusion force, and like sensors may be provided on the inside or the outside of any nozzle, or on an interstitial substrate layer on the inside or outside of any nozzle. The sensors may be provided about the center access through the nozzle, longitudinally along the center access of the nozzle, or at any of various points along the nozzle, wherein the placement or shape of such sensors may vary in accordance with the type of sensing to be performed by the subject sensor.
1. A 3D print nozzle, comprising:
an inner chamber comprising an inner facing side and an outer facing side, wherein the inner facing side encloses and is in direct contact with printing material, the printing material having a dynamic viscosity while within the inner chamber, and the inner chamber terminating in an orifice capable of outputting the printing material;
an outer shank around the inner chamber, wherein the outer shank includes the orifice, wherein the outer shank comprises an inner facing side and an outer facing side, and at least one nonconductive area that is on the outer facing side of the outer shank, wherein the at least one nonconductive area interconnects traces and sensors such that a sheath and the sensors are communicatively coupled;
the sheath is on the outer facing side of the outer shank, the sheath comprising traces that are communicatively connected to the sheath;
a collet suitable to be mechanically coupled to a distal portion of the outer shank, wherein the collet is communicatively connected to the traces; and
a plurality of applied coatings, wherein the applied coatings are applied to the inner facing side of the inner chamber.
2. The 3D nozzle of claim 1 , wherein the inner chamber comprises glass, wherein the applied coatings comprise a deposited dielectric layer, wherein the deposited dielectric layer is on a substrate of the glass of the inner chamber to create an integrated resistance temperature detector (RTD) of the sheath.
3. The 3D nozzle of claim 2 further comprising traces, wherein the traces are connected to the integrated RTD of the sheath.
4. The 3D nozzle of claim 3 , wherein the traces are integrated into the sheath.
5. The 3D nozzle of claim 1 , wherein the inner chamber comprises of glass, ceramic, or metal materials.
6. The 3D nozzle of claim 1 further comprising:
a means for sensing temperature of the nozzle.
7. The 3D nozzle of claim 1 further comprising:
a means for sensing strain of the nozzle.
8. The 3D nozzle of claim 1 further comprising:
a means for sensing strain of the nozzle; and
a means for sensing temperature of the nozzle.
9. The 3D nozzle of claim 8 further comprising:
a means for sensing pressure of the nozzle.
10. The 3D nozzle of claim 1 , wherein the inner chamber comprises ceramic.
11. The 3D nozzle of claim 1 , wherein the sensors are capable of sensing an aspect of flow rate of the printing material.
12. The 3D nozzle of claim 11 , wherein the collet is associated with a board suitable to pick up trace pads associated with the traces to communicatively connect the traces.
13. The 3D nozzle of claim 12 , wherein the collet being suitable to be mechanically coupled to the distal portion of the outer shank is further suited to be connected to a printhead as an interconnection.
14. The 3D nozzle of claim 13 , wherein the collet as the interconnection provides electrical connectivity to the printhead.
15. The 3D nozzle of claim 14 , wherein the collet is capable of being removed from the printhead.
