Preučevanje vpliva krmilnega algoritma in pozicije temperaturnih zaznaval na proces krmiljenja temperature v toplotni komori za 3D tisk polimernih materialov s taljenjem in nanašanjem

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.

Abstract

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.
