The Impact of Temperature Changing on Dimensional Accuracy of FFF Process

Abstract: Fused filament fabrication (FFF) is a process that produces 3D printed models by addition of solid material. All printed prototypes should have best accuracy to satisfy all requirements. In the current research was investigated if the parameter of fused filament temperature has an influence on accuracy of 3D printing. A low cost 3D printer called Ultimaker was used to print the items. Polylactic acid (PLA) was used as main polymeric material for printing. All dimensions (six points) of the models were measured with a micrometer (range 0-25mm).
