| Abstract Scope |
Liquid metal jetting requires a reliable build plate and part interface that provides sufficient adhesion during printing for part stability and heat transfer, while still allowing low-force removal after the build. This work examines adhesion behavior and build plate durability for LMJ parts printed on nickel-coated brass plates. Adhesion is quantified using a torque-based removal method under just printed, room-temperature, and quenched states, to compare how thermal history affects release behavior. Repeated printing at the same build locations is used to evaluate how adhesion changes with plate reuse and coating degradation. Surface metrology and microscopy are used to assess coating loss, surface damage, and material transfer at the part-plate interface, and these observations are related to removal behavior and interface quality. The results provide a practical framework for balancing attachment, release, and plate life in LMJ, and establish a starting point for future studies of alternative interfacial coatings. |
