20.500.12556/RUL-172139 Preučevanje vpliva krmilnega algoritma in pozicije temperaturnih zaznaval na proces krmiljenja temperature v toplotni komori za 3D tisk polimernih materialov s taljenjem in nanašanjem Studying the influence of the control algorithm and the position of temperature sensors on the temperature control process in a heat chamber for 3D printing of polymer materials by melt deposition Temperatura obdajajočega medija ima pomemben vpliv na proces 3D tiska polimernih materialov. Večina strojev za 3D tisk ne omogoča nastavitev in zagotovitev temperature obdajajočega medija, ki se razlikuje od temperature prostora, v katerem tiskalnik obratuje. V določenih primerih vzdrževanje različne temperature medija, ki obdaja proces 3D tiska, lahko izboljša kakovost tiska. V zaključni nalogi smo načrtovali in izdelali toplotno komoro, namenjeno krmiljenju temperature okoliškega zraka med 3D tiskanjem polimernih materialov. Komora je namenjena testiranju vpliva krmilnih algoritmov na temperaturni odziv znotraj komore. Testirali smo pet različnih krmilnih algoritmov in jih med seboj primerjali. Ugotovili smo, da so preprostejši algoritmi (kot recimo On-Off krmiljenje) hitreje dosegli referenčno temperaturo, bolj sofisticirani algoritmi (recimo PID krmiljenje) so se pa bolje odnesli v fazi vzdrževanja temperature blizu referenčne vrednosti. The temperature of the surrounding medium has a significant impact on the process of 3D printing polymer materials. Most 3D printers do not allow for the adjustment and control of the surrounding medium’s temperature, which usually matches the ambient room temperature in which the printer operates. In certain cases, maintaining a different surrounding medium temperature during the 3D printing process can improve print quality. In this thesis, we designed and built a thermal chamber intended for control of the ambient air temperature during the 3D printing of polymer materials. The chamber is used to test the impact of different control algorithms on the temperature response within the chamber. We tested five different control algorithms and made a comparison. We found that simpler algorithms (such as On-Off control) reached the reference temperature in a shorter time. However, more sophisticated algorithms (such as PID control) better maintained the temperature when the error between the actual and target temperature was small. toplotne komore Arduino krmiljenje temperature krmilni algoritmi 3D tiskalniki heat chambers Arduino temperature control control algorithms 3D printers true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-06 08:31:03 2025-09-06 08:31:05 2025-10-07 03:37:54 0000-00-00 00:00:00 2025 0 0 X, 35 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.2:681.536.5:004.925.8(043.2) 275630 248197891 43464.pdf 43464.pdf 1 88235672E495E5C6697F677B3F0AA461 4b51bd7e28eda6f738bea3113cfdf921f5d3462550f6275a56390b319b4cd2be eb81d9ef-8aea-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215940 Fakulteta za strojništvo 0 0 0
