Abstract Scope |
In Material Extrusion (MEX), Wood Fibre Reinforced PLA embodies a sustainable promising alternative to standard PLA and Short Carbon Fibre Reinforced PLA (SCF-PLA) because of its enhanced mechanical characteristics and full biodegradability. By aligning the wood fibres to the direction of the load, Multi-Axis Material Extrusion (MAMEX) could further enhance the capabilities of WF-PLA. This paper compares the mechanical behaviour of WF-PLA, PLA and SCF-PLA samples made using 4 and 5 axes MEX. In 4-axes MEX, the results show that WF-PLA samples display 27% poorer ability to resist the applied loading than PLA, and 37% poorer than SCF PLA. Whereas in 5-axis MEX, WF-PLA samples were able to withstand the same amount of force as the PLA samples, but over a longer period. This research highlights that Wood Fibre-reinforced materials could be beneficial to the AM community and further development is required to fully exploit their opportunities. |
