Izvleček
3D tiskanje je tehnološki postopek izdelave objekta v prostoru. Pri eksperimentalnem delu smo uporabili tiskalnik Sharebot, ki deluje po FDM metodi ciljnega nalaganja snovi. V sklopu diplomske naloge nas je zanimala problematika dimenzijske stabilnosti in toleranc izbranega vzorca pri različnih hitrostih tiskanja. Tiskali smo pri hitrostih pomika šobe 1500 mm/min, 2500 mm/min in 3500 mm/min. Na podlagi meritev je bilo ugotovljeno, da je izdelek manj odstopal od idealne oblike pri tiskanju z nižjo hitrostjo. Relativna napaka je bila pri daljših dimenzijah manjša in je znašala do 0,8%. Pri krajših dimenzijah je relativna napaka izmerkov dosegla tudi 3,6%. Največja absolutna napaka pri hitrosti 1500 mm/min je znašala 0,17 mm, pri tiskanju s hitrostjo 3500 mm/min pa 0,28 mm. Tudi merilna negotovost se je z višanjem hitrosti tiskanja povečevala.

Naslov:The effect of printing speed on the geometrical stability of 3D printed samples
Izvleček:
3D printing is a technological procedure of manufacturing solid objects. During the experiment, we were using 3D printer Sharebot which is based on fused deposition modeling. The material, shaped like a wire or filament, is fed from a coil into a heated printer extruder head. Filament is then extruded through a nozzle and deposited on the platform. The procedure is repeating itself until the solid model is made. We were especially interested in geometrical stability of the samples that were obtained by using various printing speeds. We printed 3 series of samples, each printed with different printing speed. Manufacturing parameter varied between 1500 mm/min and 3500mm/min. After the printing process, we measured the samples and performed optical evaluation. Based on given results we realized that the samples, printed with the slowest printing speed had the best geometrical stability. Estimation of measurement uncertainty, absolute and relative error of measured samples increased with increased printing speed. Relative error of measured samples increased from 0,8% to 3,6% due to smaller dimensions. Absolute error of measured samples increased from 0,17 mm to 0,28 mm with higher printing speed.
