This episode is dedicated to Lorrie Michele Parson.
Andrew Cannon started 1900 Engineering to commercialize a microcontact printing-based technology to map strain in high performance materials. His technology helps engineers understand when and how parts fatigue, knowledge that is critically important for industries ranging from aerospace to automotive. We talk about how 1900 Engineering's technology works and how the stamps are fabricated, but also discuss a number of the long-standing challenges to precision patterning at the micrometer and nanometer length scale.
