Bioplastic Modified with Woodflour for Additive Manufacturing

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 1216)


Additive manufacturing (AM) is considered the new industrial revolution due to its impact in the way parts are manufactured. Research vast majority is focused on technology development based on different processes. However, recent trends show a big pushed for materials development and testing. Most of the thermoplastic used in AM are petroleum based, a limited and nonrenewable resource, however, bioplastics such as polylactic acid (PLA) have gained traction as a competitor. In this research, PLA was mixed with woodflour into different matrices to evaluate the particle size effect, species (maple and pine) and concentration (woodflour amount) in the biopolymer and 3D printed parts performance. Thermal, mechanical, structural properties were studied for the different matrices created. Results showed the potential of using woodflour as an additive to enhance bioplastics, maintaining sustainability aspects and changing the biopolymer to be suitable for AM.
