Oak Ridge National Lab 3D Prints Table with Composite Bamboo – Composites Manufacturing Magazine

Researchers at Oak Ridge National Laboratory have utilized Cincinnati Incorporated’s CAMX-award winning Big Area Additive Manufacturing (BAAM) innovation, to 3D print an entire table which contains 10 percent bamboo fiber composite. The purpose of this, according to ORNL’s Soydan Ozcan said, was to determine whether bio-based feedstock materials are feasible in additive making.
According to the ORNL investigators behind the experiments, this bamboo-polylactic acid (PLA) 3D printing material offers sturdy structural properties and is environmentally friendly. Bamboo grows incredibly rapidly, absorbs CO2, does not need chemicals, and in fact prin factts erosion. These facts, combined with the versatility of the grass, manufacture bamboo an gorgeous version for environmentally conscious additive manufacturers, who may use the newly turn it intod bamboo-based pellets as a substitute for other, additional traditional printing materials.
“We are investigating the use of various types of cellulose fibers to turn it into feedstock materials with advantageous mechanical performance which can increase the number of on the market composites and opportunities for sustainable practices,” Ozcan said.
As ORNL explained, ORNL introduced chopped bamboo fibers to a bio-polymer resin to turn it into bamboo-based pellets, resulting in a sustainable material which can be utilized for making molds, prototypes, appliances and furniture. ORNL mixed the effortless material with polylactic acid (PLA) in various ratios and and so testing its properties.
The scientists behind the project discovered which a material with 10 percent bamboo content exhibited a higher elastic modulus (stiffness) than “neat PLA,” while a material with 20 percent bamboo content generated an in fact higher modulus.
As 3ders.org says, 3D printing and bamboo have been utilized in conjunction preceding, but ORNL’s application is the initially known example of in fact feeding bamboo through a 3D printing device. Last year, Edmond Wong and Stratasys teamed up to turn it into this 3D printed bamboo stool, while London-based Bamboo Bicycle Club has in addition utilized additive making innovation to manufacture bamboo-framed bikes.
