Reclamation of Waste Sand Generated from 3D Printer.

Three-dimensional (3D) printing is rapidly converging with the foundry industry in the recent years and tends to increase more in upcoming years. 3D printing is largely used for making sand molds and printing process uses sand which is imported. This sand in terms of costing is very high in comparison to Indian sand used in sand metal casting. Thus, waste generated from the printer is not affordable and increases the initial printing cost. To reuse the sand, reclamation is the solution which is effective and will reduce the initial printing cost. As the initial cost decreases printing process can be used for mass production of molds and cores. This paper presents a study of reclamation done on two types of waste sand printed and loose sand. It also suggests a range of temperature for reclamation of both the type of waste sand. Thermal process of reclamation is used as the binder used in the printing process is furan base. As furan binder evaporates at a certain temperature, the sand can be reclaimed and reused. [ABSTRACT FROM AUTHOR]
