The aim of this study is to investigate the relationship between the fusion temperature and dimensional
accuracy of the 3D printed components. The Computer Aided Design (CAD) model of specimens
were prepared using Autodesk Inventor Software. Then the models were exported as STL file format
for rapid prototyping. Prusa İ3 desktop type 3D printer with 90-300 microns layer height
manufacturing capacity was used to produce the samples. The printer settings were prepared with
Simplified3D software. Infill density and layer height of specimens were determined as 20% and 200
microns, respectively. The heated bed temperature was selected as 60°C to increase the bonding and
surface quality. The specimens were produced as sphere with the diameter of 10 mm. The samples
were manufactured with five different extruder temperatures (185, 195, 205, 215, and 220°C) that
directly affect the fusing temperature and process. Three samples spheres were produced for each
fusion temperature. After the design and manufacturing processes the dimensions of produced samples
were measured with image processing techniques. The obtained results were compared with each other
to find the relationship between the dimensional accuracy and fusion temperatures. The results showed
that the minimum dimensional error was obtained from the fusion temperature of 185°C with the value
of 0.290797 mm and percentage of 3%.
