Abstract

Additive manufacturing (AM), also known as 3D printing, is a fabrication method used to create geometric 3D objects. Particularly, binder jetting 3D printing (BJ3DP) can be used to produce complex geometries. In this study, we have enhanced the compressive strength of alkali-activated materials (AAM)-based BJ3DP outputs by optimizing the powder mixture, post-processing machine, and post-processing storage solution. These optimization measures present a compressive strength of 22.56 MPa at 7 days (20 mm ×20 mm ×20 mm sized printed output). Consequently, we have confirmed the possibility of the application to construction by enhancing the compressive strength of BJ3DP.
