20.500.12556/RUL-130441 Krmiljenje temperature fotopolimera za stereolitografsko tiskanje Photopolymer temperature control for stereolithographic printing 3D tisk omogoča relativno hitro izdelavo prototipov kompleksnih oblik. Kot prva aditivna tehnologija se je uveljavila stereolitografska tehnologija 3D tiska. Pri tem načinu izpostavimo fotopolimer UV svetlobi in ga tako na izpostavljenih mestih strdimo. Plasti se nalagajo ena na drugo in tako na izdelovalni mizici nastane izdelek. V zaključni nalogi smo se posvetili problemu vpliva temperature na reakcijo fotopolimerizacije. V prvem delu smo pregledali literaturo in predstavili aditivne tehnologije ter kakšen vpliv ima na končni izdelek temperatura, pri kateri tiskamo. Na podlagi ugotovljenih dejstev smo izbrali ustrezen način krmiljenja temperature ter komponente, ki bodo uporabljene v krmilnem sistemu. Sistem smo preizkusili v kadi tiskalnika polni vode. Med preizkusi smo merili temperaturo vode in PWM signal mikrokrmilnika. Na podlagi meritev smo optimizirali koeficiente PID krmiljenja. 3D printing enables relatively fast prototyping of complex shapes. Stereolithographic 3D printing technology was the first additive technology. This technology uses UV light to harden photopolymer in desired spots. The layers are stacked on top of each other, creating a part on the production table. In the final thesis, we focused on the problem of the influence of temperature on the photopolymerization reaction. In the first part, we reviewed the literature and presented additive technologies and what effect has the temperature at which we print on the final product. Based on the established facts, we selected the appropriate method of temperature control and the components that will be used in the control system. We tested the system in a printer vat full of water. During the tests, we measured the water temperature and the PWM signal of the microcontroller. Based on the measurements, we optimized the PID control coefficients. stereolitografija 3D tiskanje fotopolimer PID krmiljenje Arduino temperatura stereolithography 3D printing photopolymer PID control Arduino temperature true false false [A.
