Mechanical properties of parts from fused filament fabrication has been made known to be directionally dependent or in other word anisotropy. Several common process parameters were varied to study their impact on the mechanical properties, in particular compression and bending strength of the end product in the material of wood PLA. The Taguchi method was used to design and simplify the experiment without compromising the experiment’s efficiency. S/N ratio from Taguchi analysis was interpreted for determining the optimum combination of process parameter for the highest compressive and bending strength. The build orientation angle is the major factor contributing to higher compression and bending strength recorded followed by infill density and lastly layer thickness. The maximum value for compressive stress is 98.9 MPa with 0° built orientation, 0.15mm layer thickness and 60% infill, while for bending stress it is 73.6 MPa with 0° built orientation, 0.20mm layer thickness and 100% infill.
