Abstract

Three-dimensional (3D) printing systems include a 3D printer that includes a print bed that has one or more walls arranged to enclose a basin configured to contain a printing material. A compression plate is configured to fit slidably within, or on top surfaces of, the one or more walls of the print bed. A bottom plate forms a base of the basin and is configured to fit slidably within the one or more walls of the print bed. An elevation controller moves one or both of the compression plate and the bottom plate towards each other to apply a specified compressive force on printing material within the basin. The compression plate and the bottom plate together seal the basin sufficiently to avoid leakage of the print material from the basin.
