Printing wrinkles

The findings of the experiments were observed by the researchers to confirm their analytical model.Structured composites of varying stiffness and geometries were created by the team using a multimaterial 3-D printer.

All examples held a similar defined setup.Li asserts, “3-D printing is a fast prototyping technology.”It is very easy to use when making parts with multiple materials and complicated geometries.We are able to print materials with microstructures, and we know exactly what their properties are.

After that, the group put each sample into a mechanical compression machine, measured the load that caused the material to wrinkle, as well as the resulting wrinkling patterns.Their measurements ended up being very close to what their model had predicted.
