  - "Enabling additive manufacturing to employ a wide range of novel, functional materials
    can be a major boost to this technology. However, making such materials printable
    requires painstaking trial-and-error by an expert operator,\r\nas they typically
    tend to exhibit peculiar rheological or hysteresis properties. Even in the case
    of successfully finding the process parameters, there is no guarantee of print-to-print
    consistency due to material differences between batches. These challenges make
    closed-loop feedback an attractive option where the process parameters are adjusted
    on-the-fly. There are several challenges for designing an efficient controller:
    the deposition parameters are complex and highly coupled, artifacts occur after
    long time horizons, simulating the deposition is computationally costly, and learning
    on hardware is intractable. In this work, we demonstrate the feasibility of learning
    a closed-loop control policy for additive manufacturing using reinforcement learning.
    We show that approximate, but efficient, numerical simulation is\r\nsufficient
    as long as it allows learning the behavioral patterns of deposition that translate
    to real-world experiences. In combination with reinforcement learning, our model
    can be used to discover control policies that outperform\r\nbaseline controllers.
    Furthermore, the recovered policies have a minimal sim-to-real gap. We showcase
    this by applying our control policy in-vivo on a single-layer, direct ink writing
    printer. @eng"
