Binder-jetting 3D printer capable of voxel-based control over deposited ink volume, adaptive layer thickness, and selective multi-pass printing.

The limited control over the printing process in commercial powder bed 3D printers hinders the exploration of novel materials and applications. In this study, a custom binder-jetting 3D printer was developed. The resulting fine-grained control over the printing process enables features such as voxel-based control over the printed ink volume, adaptive layer thickness, and selective multi-pass printing.
