Hybrid Novel Additive Manufacturing for Sustainable Usage of Waste

Abstract

Additive manufacturing (AM) encompasses many forms of technologies and materials as 3D printing is being used in almost all industries. The variety of materials used includes but is not limited to plastics, ceramics, resins, metals, sand, textiles, biomaterials, glass, and food. Currently, in 3D printing technology, the printing mode of direct writing forming is widely applied. The raw material used is ceramic powder, and the direct writing forming of the ceramic could be applied to various fields of materials, chemistry, chemical engineering, and the like. This work is aimed at printing the nanopowder of nonsegregated waste into conventional components. The work is related to a system for converting nonsegregated waste material into the synthesized dough, comprising of a chamber, an ultraviolet (UV) disinfectant unit, a shedder, and a storage unit. The nonsegregated waste material is stored inside the chamber which dispenses the nonsegregated waste material into the UV disinfectant unit; said UV disinfectant unit removes the harmful germs and water content in the nonsegregated waste material to form solid waste. The disinfected solid waste enters the shedder which powders the solid waste. The powdered solid waste is stored in the storage unit. The powdered solid waste is mixed with components in a mixer to form a synthesized dough. The synthesized dough as the printable source is sent to a 3D printer which prints desired final component. The hardness value obtained for the printed component is 70 Brinell hardness units.
