Mortar for 3D printers using river sand, Portland cement and hydraulic lime

Abstract

The 3D printing is a construction technology that uses mortar to make elements and structures. In this research, four types of mortar were elaborated using Portland cement types I and HE, adding hydraulic lime. Mortars with cement types I and HE without hydraulic lime presented higher resistance to compression than mortars made with lime. The four mortars had an adequate resistance to compression and features that are suitable for use in 3D printers.
