Study on Printability of Mortar for 3D Printing

Abstract

Abstract: Observational methods are widely used to assess the printing performance of 3D printing materials in current research and technical standards, lacking of quantitative evaluation for extrudability and constructability. In this paper, based on the influences of conventional working performance indicators such as fluidity on printability, two quantitative indicators of extrusion uniformity and cumulative deformation rate were proposed to evaluate the printability of 3D printing materials, and the relationship between conventional working performance indicators and printing quality was established under experimental conditions. The results show that the extrusion uniformity of 3D printing mortar increases first and then decreases with the increase of fluidity, and decreases with the increase of dynamic yield stress. The cumulative deformation rate decreases with the increase of height retention rate and decreases with the increase of static yield stress. Under the conditions of this test parameters, when the extrusion uniformity is less than 3.5%, the cumulative deformation rate is not more than 6%, the dynamic yield stress is 200～800 Pa, and the static yield stress is 1 800～3 300 Pa, the number of printing layers of mortar is higher (not less than 30 layers), and the printability is better.

Key words: 3D printing, extrudability, constructability, extrusion uniformity, accumulated deformation rate, evaluation method
