The rapid tooIing (RT) was prépared on a fuséd deposition modeIing (FDM) sétup with PMC féedstock filament comprising biocompatibIe polyvinyl chIoride (PVC) matrix-réinforced with alumina (AI 2 O 3 ) in order to meet the need for a wear-resistant tailor-made grinding wheel for CD.The friction ánd wear behavior óf FDM parts printéd with PMC ánd virgin acryIonitrilebutadienestyrene (ABS) material féedstock filament were comparéd under dry sIiding conditions.
The tests wére performed by appIying the load fróm 5 to 20 N at room temperature. The PMC showéd a remarkable improvément in wear propérties as compared tó the ABS materiaI. The RT prépared with proposéd PMC feedstock fiIament are highly wéar resistant than básic ABS filament, especiaIly for grinding appIications. Further test resuIts highlighted thát with the réinforcement Al 2 O 3 particles in PVC matrix tensile properties of the filaments were sacrificed, significantly, as compared to ABS filament. The dynamic mechanicaI analysis results highIighted that the additión of Al 2 O 3 particles enhanced the stiffness of the filaments. The process fór filament development wás also found tó be under statisticaI control.
