Researchers at Michigan Technological University (Michigan Tech), the United States, have been developing solar-powered 3D printers, and lately seem to be directing their overall attention towards making 3D printing technology more environmentally friendly. The proof that Michigan Tech has been looking to develop more sustainable additive manufacturing processes certainly exists outside of their research on solar-powered 3D printing. In fact, one group of students have recently launched a business to manufacture and sell recycled and biodegradable filaments.

The company, which is called Superior Filament, was started by a group of four Michigan Tech students who have been producing plastic filaments since 2015. Their main objective is to promote environmental sustainability in 3D printing, aiming to reuse discarded plastic pollutants instead of creating more. The method that they’re developing will transform our everyday plastic waste, such as soda bottles, water bottles, milk jugs and many others, into high-quality 3D printing filament.

Though not all of their available filaments are 100% environmentally friendly, the ultimate goal of offering recycled filament for a fraction of the average price seems near in sight. Superior Filament is already offering rPET (available for pre-sale at $24.95), which is made from household items such as soda bottles and water bottles, and rABS ($29.95), a spin on the commonly used material made from the same plastic as car battery cases and Legos.

Both of these filaments can be purchased on the Superior Filament website.
