The Council for Scientific and Industrial Research (CSIR) and South African additive manufacturing (3D printing) filament producer Filament Factory have collaborated to develop a new nano-reinforced polymer composite material that the CSIR describes as “groundbreaking” and setting a “new benchmark”. The news was released on Wednesday.

“This collaboration marks a significant step forward in South Africa’s materials science capabilities,” affirmed Department of Science, Technology and Innovation-CSIR Nanotechnology Innovation Centre manager and chief researcher Professor Suprakas Sinha Ray. “The nano-reinforced composite not only outperforms traditional materials but also opens doors for local innovation in critical industries such as aerospace, electronics, and healthcare.”

The new material provides greater shielding against electromagnetic interference as well as greater radio frequency absorption (in the C-band and X-band regions of the electromagnetic spectrum). It is also light in weight, and has outstanding electrical conductivity, thanks to having nanotechnology integrated into it.

“Nano-reinforced polymer composites shield electromagnetic interference and enhance electrical conductivity, making them ideal for stealth technologies, radar-absorbent materials, conductive medical implants, sensors, and electronic devices,” he highlighted. Thus, the new material has potential applications in all five of these areas.

The new material provides an excellent combination of strength and functionality. Its structure and composition are unique. It is available in both filament and granule form, providing flexibility for a range of manufacturing processes. These include 3D printing, extrusion, and injection moulding. Its strength and lightness make it appropriate for applications that absolutely require a combination of durability and reduced weight.  

“[The] CSIR is committed to pushing the boundaries of materials science and providing innovative solutions to meet the evolving needs of industries worldwide,” assured the agency. “The nano-reinforced polymer composite represents a significant step forward in the development of advanced materials with transformative potential. Globally, the 3D printing market is concentrated in North America, Europe and Asia-Pacific. Significant advancement [sic] in unmanned aerial applications, electronic vehicles, [and the] health care sector underpin the potential for 3D printing technology to expand. We intend [to] expand the portfolio of applications beyond the imagination and it is possible through national and international collaborations.”
