Binder jetting of strong green parts with a crosslinker

Abstract

A method is disclosed for binder jetting of strong green parts using a crosslinker to form covalent bonds among binder molecules. In the disclosed process, a powder and a binder are prepared, and a crosslinker is introduced either by premixing with the binder or powder, or by in-situ deposition through a printhead. During the printing process, the binder and crosslinker are selectively jetted into the powder bed to form green parts layer by layer. The green parts are subsequently cured to induce crosslinking and solvent removal, resulting in chemically bonded binder networks. This method enables the fabrication of mechanically robust green parts without requiring high-temperature sintering, thereby allowing use with heat-sensitive materials. The approach is applicable to a wide range of binders, powders, and crosslinkers, and is particularly suited for manufacturing sorbent structures for carbon capture, water treatment, and catalytic applications.
