Utilizing recycled materials in additive manufacturingAdditive manufacturing offers a solution for repurposing glass wasteGlass waste, addressing significant environmental concerns. This investigation explores using waste glass bottles for manufacturing bricks via Direct Ink Writing (DIW). Bricks with unique geometries were produced from yellow clayClay in Campos dos Goytacazes, Brazil, with 30% glass wasteGlass waste powder. To reduce water content, 3 wt% of citric acid, 1 wt% cornstarch, and 0.2 wt% sodium silicate were evaluated. DensityDensity and length width, and height shrinkage tests were used to assess the material’s properties. Raw materials were characterized using X-ray fluorescence (FRX). Compression strength analysis was conducted to understand mechanical propertiesMechanical properties and sample variability. Additionally, a scanning electron microscopyScanning electron microscopy (SEM) test was used to analyze the microstructureMicrostructure of the raw materials and manufactured samples. The integration of glass residue in the production of ceramic pieces through additive manufacturingAdditive manufacturing not only enhances the properties and performance of the final products but also represents a sustainable approach by minimizing environmental waste.
