DURIP DATA-DRIVEN MULTIMATERIAL ADDITIVE MANUFACTURING OF ACTIVE ARCHITECTED MATERIALS
Abstract
Multimaterial 3D printing has enabled the efficient construction of systems with unprecedented compositional and geometric complexity. This has enabled not only improvements in traditional mechanical properties such as specific stiffness, but also fundamentally new behaviors in materials systems, such as the ability to autonomously change shape or mechanical properties in response to the environment, or to even perform combinatorial logic on these environmental inputs. However, these complex behaviors are entirely dependent on precise control of the internal geometry, the quality of the interfaces between distinct materials, and subtle variations in the boundary conditions of the geometric features. This challenge is exacerbated by the fact that the printing process is imperfect, introducing both systematic and stochastic defects to the desired geometry and to the material interfaces. Understanding and characterizing the 3D internal structure is essential for generating better process-structure-property relationships for multimaterial architectures (and, hence, better device performance). Yet such thorough characterization is impossible to achieve after fabrication is complete.
