Thermoplastic polymer nanocomposites (PNCs) play a pivotal role across industries, embodying versatility and multifunctionality through the synergistic combination of different nanomaterials and polymers . Considering the increasing prevalence of 3D printing in industrial settings, there is a strong need for the development of multifunctional PNCs that are compatible with 3D printing technologies. Achieving this requires not only material design but also thorough optimization of printing settings to assure material printability and achieve the specified attributes and printing quality . However, this process requires balancing multiple aspects and managing their interconnections in terms of process optimization and material design. The 3D printing process involves various factors (for example, build orientation, build sequence, slice height, printing speed, flow rate, nozzle size, layer thickness, extrusion temperature, and bed temperature) that significantly influence the ultimate quality and final properties of the printed part . In addition to the process parameters, material properties such as thermal, mechanical, and rheological properties have a substantial impact on printability and overall performance.
