Experimental Characterization of Polyamide 12/Phosphogypsum Composites Using Phosphogypsum from OCP Morocco via Selective Laser Sintering

Selective laser sintering (SLS), an additive manufacturing technique, enables the development of products with distinct properties for various applications. This study develops and characterizes a phosphogypsum-based polyamide 12 composite powder using phosphogypsum from OCP Morocco as a mineral filler for selective laser sintering. The work examines thermal, chemical, and microstructural properties through TGA, DSC, LFA, and SEM analysis, demonstrating the potential of phosphogypsum-based PA12 powders for more sustainable additive manufacturing applications.
