Chula Converts Ocean Plastic into 3D Printing Filament

Chulalongkorn University has developed a method to recycle discarded fishing nets into usable 3D printing filament, turning marine waste into a valuable resource.
BANGKOK, April 6, 2026 /PRNewswire/ — Chulalongkorn University researchers have unveiled a new recycling process that transforms discarded fishing nets into high-grade filament for 3D printers. The innovation addresses the growing problem of marine plastic waste, particularly "ghost gear," by converting it into a valuable manufacturing resource. The technology, developed by the university's engineering team, processes nylon and other polymers from old nets into consistent, durable filament suitable for industrial and consumer 3D printing applications. This approach supports a circular economy model by keeping plastic out of oceans and estuaries while creating a new revenue stream for coastal communities involved in collection and sorting. "This initiative turns an environmental hazard into an economic opportunity," stated a lead researcher. The project aims to scale production and partner with recycling cooperatives to source nets directly from fishermen, thereby supporting local livelihoods while tackling a critical source of ocean pollution.
