Résumé :	This work focuses on the development and manufacturing of abrasive discs composed of resin filled with glass and alumina, using advanced 3D printing technology. By optimizing the formulation and distribution of the glass and alumina particles within the resin matrix, the process achieves superior mechanical strength, wear resistance, and precision in the final product. The use of 3D printing allows for the customization of disc geometry and abrasive properties, making these discs highly suitable for demanding industrial grinding and polishing applications.
