Contribution to the Formulation of a Material Based on Marble Waste for Its Use in 3D Printing in Civil Engineering

The objective of this research is to experimentally study the way of recovery and recycling of marble processing waste mixed with other materials for 3D printing in Civil Engineering. In this paper, we present the framework of this study and the approach to be followed in the feasibility study of the use of Tunisian marble powder in the formulation of a printable material in Civil Engineering. Local materials from Tunisia (marble rock processing waste), now considered as waste, will be recycled in the field of additive manufacturing. We propose an experimental protocol and the first results of the characterization of the raw materials used. In particular, the marble powder used is calcium-dominant and contains a low percentage of Quartz and Dolimite, It has a density of 1.22.
