Additive Manufacturing with Environmentally Sustainable Materials for Shell Envelop System

Abstract:

This paper presents research on the rheology of earth-based composites for Additive Manufacturing (AM) The study experiment setup is based on using different types of natural fibers with earth hydraulic binders through a pneumatic extrusion system of a 3axis printing machine. The ingredients of the composites are eco-friendly, locally available, inexpensive, and driven from recycled sources. The line tests have been done to improve important parameters related to extrudability, plasticity, and fluidity of the material composite through the printing process.
