Researchers at the Oak Ridge National Laboratory are using bamboo fibre in 3-D printing experiments to determine whether bio-based feedstock materials are feasible in additive manufacturing.
Chopped bamboo fibres were added to a bio-polymer resin to create bamboo-based pellets, resulting in a more sustainable material that can be used for manufacturing moulds, prototypes, appliances and furniture. The research team 3-D printed a table that contains 10 percent bamboo fibre composite.
Researchers behind the experiments developed 10% and 20% bamboo PLA composites which are 100% bio-based and fully sustainable. Structural and environmental benefits behind bamboo make it and interesting option for additive manufacturers, who could use the newly developed pellets as a substitute for more traditional printing materials.
Researchers are investigating the use of different types of cellulose fibres to develop feedstock materials with better mechanical performance that can increase the number of available composites and opportunities for sustainable practices.
