| description | The invention relates to a binder jetting 3D printing method. The binder jetting 3D printing method comprises the steps that printing materials are selected, wherein the printing materials comprise casting sand or ceramic powder, a liquid curing agent and a solid curing agent; in the sand mixing process, printing materials are sequentially added into a sand mixing tank to be evenly mixed; in the printing process, powder laying and ink jetting work are circularly carried out to complete printing work, and a selected binder is an inorganic binder; normal-temperature curing: after printing is completed, normal-temperature curing is performed for preset time, and sand is removed to obtain a printed green body; and secondary hardening is conducted, specifically, the printed green body obtained after sand removal is dried for a preset time so that secondary hardening can be achieved. According to the scheme, the problems that an existing inorganic binder is slow in normal-temperature hardening and low in strength, |
