This paper investigates the effectiveness and the accuracy of open source 3D printer of Mendel Max and Kossel Mini which the additive manufacturing technique of Fused Filament Fabrication (FFF) was implemented.A benchmark of the 3D printer test model was designed based on critical features of AM process i.e. hemispheres, cube,cylindersand slots.The benchmark was produced by both machines using variation FFF parameters of layer height and infill density.In addition,the material of FFF was varied between PLA and ABS for each test.The dimensional accuracy of the part features were measured by the nominal dimension of the part using Profile Projector DS600.In addition,TR200 roughness tester was used to measure the surface roughness.The result shows that for dimensional accuracy results,Mendel Max machine has a lower deviation result compared to Kossel machine. Furthermore,PLA filament gives better result compare to ABS filament in term of surface quality finishing for both machines.The result shows that for both 3D printer machines,the quality and accuracy of the part features are better when the layer thickness is 0.178 and 20% of infill density.
