AI Technical Summary
Conventional liquid metal jet printing systems face issues with inconsistencies in build strength, adhesion, porosity, surface finish, cracking, and z-height errors due to inadequate interfacial temperatures and thermal processes, requiring secondary machining and finishing processes that reduce productivity and increase costs.
The implementation of a targeted heating system that heats the substrate and area proximal to it, using lasers to control interfacial temperatures and temperature gradients, thereby modifying grain size, growth, and structure of the metal droplets to improve mechanical properties and surface finish without the need for post-printing processes.
This approach enhances build strength, adhesion, and surface finish while preventing cracks and fractures, maintaining productivity by integrating heating within the printing process, thus eliminating the need for secondary operations.
