Abstract

A method for printing a strain sensor on a component using an aerosol ink, the method including depositing the aerosol ink on the component using a print head, the aerosol ink comprising chromium containing particles, and monitoring a printing environment parameter associated with printing environment conditions to confirm the printing environment parameter is within a predetermined environmental range of a printing environment parameter baseline value while depositing the aerosol ink on the component using the print head, the printing environment parameter baseline value a predetermined preferred printing environment parameter value within the predetermined environmental range, the monitoring including monitoring an atmospheric composition of the printing environment.

First claim

What is claimed is:

1. A method for printing a strain sensor on a component using an aerosol ink, the method comprising:
depositing the aerosol ink on the component using a print head, the aerosol ink including chromium containing particles; and
monitoring a printing environment parameter associated with printing environment conditions to confirm the printing environment parameter is within a predetermined environmental range of a printing environment parameter baseline value while depositing the aerosol ink on the component using the print head, the printing environment parameter baseline value a predetermined preferred printing environment parameter value within the predetermined environmental range, the monitoring including monitoring an atmospheric composition of the printing environment.

2. The method of claim 1 , further including monitoring a temperature of the component to confirm the temperature within a predetermined temperature range of a baseline temperature value.

3. The method of claim 2 , wherein monitoring the temperature of the component includes controlling the temperature of the component while depositing the aerosol ink on the component using the print head.

4. The method of claim 1 , wherein depositing the aerosol ink on the component using the print head includes maintaining a print head velocity within a predetermined print head velocity range of a print head velocity baseline value.

5. The method of claim 1 , wherein monitoring the printing environment parameter includes monitoring an ambient temperature or an ambient humidity of the printing environment.

6. The method of claim 1 , wherein depositing the aerosol ink on the component using the print head includes depositing the aerosol ink on the component in a configured path.

7. A method for printing a strain sensor on a component using an aerosol ink, the method comprising:
purifying chromium containing particles to remove a contaminant;
depositing the aerosol ink on the component using a print head, the aerosol ink including the particles; and
monitoring a printing environment parameter associated with printing environment conditions, the monitoring including monitoring an atmospheric composition of the printing environment.

8. The method of claim 7 , wherein monitoring a printing environment parameter includes confirming the printing environment parameter is within a predetermined environmental range of a printing environment parameter baseline value.

9. The method of claim 8 , wherein the printing environment parameter baseline value is a predetermined preferred printing environment parameter value within the predetermined environmental range.

10. The method of claim 7 , wherein purifying chromium containing particles includes removing a reactive material.

11. The method of claim 7 , wherein depositing the aerosol ink on the component using the print head includes maintaining a print head velocity within a predetermined print head velocity range of a print head velocity baseline value.

12. The method of claim 7 , wherein depositing the aerosol ink on the component using the print head includes depositing the aerosol ink on the component in a configured path.

13. The method of claim 7 , wherein depositing the aerosol ink on the component using the print head includes printing a first strain sensor on the component and printing a second strain sensor on the component.

14. The method of claim 13 , wherein the first strain sensor defines a variability with the second strain sensor less than one percent.

15. A system for printing a strain sensor on a component using an aerosol ink, the system comprising:
a printer to deposit the aerosol ink on the component using a print head, the aerosol ink including chromium containing particles; and
a control system operable with the printer, the control system including one or more processors and memory, the memory storing instructions that, when executed by the one or more processors, cause the system to monitor a printing environment parameter associated with printing environment conditions to confirm the printing environment parameter is within a predetermined environmental range of a printing environment parameter baseline value while depositing the aerosol ink on the component using the print head.

16. The system of claim 15 , wherein the printing environment parameter baseline value is a predetermined preferred printing environment parameter value within the predetermined environmental range.

17. The system of claim 15 , further including monitoring an atmospheric composition of the printing environment.

18. The system of claim 15 , further including a printing environment parameter sensor for sensing a printing environment parameter.

19. The system of claim 15 , wherein the printer includes an atomizer and a print heat fluidly connected to the atomizer for receiving the aerosol ink from the atomizer.

20. The system of claim 19 , wherein the control system is configured to cause the system to control a temperature of the component while depositing the aerosol ink on the component using the print head.
