Abstract

A system and method for applying patterns to surfaces. A pattern may be applied to a surface of an object using a three-dimensional (3D) printer system. The 3D printer system may include a printer head including an applicator holding material used to form the pattern on the surface, a structure configured to hold a substrate to which the material will be applied, and a controller for adjusting a location of the printer head relative to a surface and initiating applying material from the applicator onto the surface. The applicator may be a syringe with a needle. 3D coordinates at which material is to be applied to a surface to form the pattern may be determined and identified based on a relative location of the substrate and the pattern. The pattern may be a speckle dot pattern used in Digital Image Correlation (DIC) material testing and characterization techniques.

Dependent claims

A method of applying a digital image correlation (DIC) pattern to a surface of a substrate, the method comprising:

determining a three-dimensional coordinate for each of one or more locations at which ink is to be applied to a surface of a substrate to achieve a predetermined DIC pattern, the three-dimensional coordinates are determined based on a location of the surface of the substrate and the predetermined DIC pattern;
adjusting a position of a printer head to a three-dimensional coordinate of a location of the one or more locations;
and
applying ink to the surface of the substrate at the three-dimensional coordinate using the printer head, the ink on the surface of the substrate having a dimension based on the predetermined DIC pattern.

A computer readable medium having stored thereon in a non-transitory state a program code for use by a computing device, the program code causing the computing device to execute a method of operating a three-dimensional printer system comprising:

identifying a three-dimensional coordinate for a dot of one or more dots of a digital image correlation (DIC) pattern to be applied to a surface of a substrate;
adjusting a position of a printer head to the three-dimensional coordinate of the dot of the one or more dots of the DIC pattern;
and
applying ink to the surface of the substrate at the three-dimensional coordinate using the printer head, the ink on the surface of the substrate has a dimension based on the DIC pattern.
