20.500.12556/RUL-155416 Kompenzacija posedanja betona med 3D-tiskanjem Compensation of concrete slumping during 3D printing Tehnologija 3D-tiskanja betona je poznana že več kot dve desetletji. V industriji se tehnologija iz leta v leto bolj širi in pridobiva na pomenu. Zaradi mase tiskanega materiala in njegovih materialnih lastnosti se izkaže, da med tiskanjem prihaja do posedanja tiskovine. V delu smo oblikovali in razvili ustrezen merilni sistem, ki je sposoben prepoznati velikost poseda in se nanjo ustrezno odzvati. Določili smo ustrezen korak vzorčenja površine za zagotavljanje zadostne natančnosti rezultatov, pri čemer smo ugotovili, da je minimalni potrebni korak vzorčenja med 5 mm in 20 mm ali celo več. Metodo smo razvili v smeri zmanjševanja pogostosti korekcij položaja, pri čemer smo obdržali enako število meritev. Concrete 3D-printing technology has been known for more than two decades. In the industry, technology is expanding and gaining importance year by year. Due to the mass of the printed material and its material properties, it turns out that the printing material slumps during printing. In this work, we designed and developed an appropriate measuring system that is capable of recognizing the size of the slumping and reacting accordingly. We defined what the appropriate surface sampling step is to ensure sufficient accuracy of the results, finding that the minimum necessary sampling step is between 5 mm and 20 mm or even more. We developed the method in the direction of reducing the frequency of position corrections, while keeping the same number of measurements. 3D-tiskanje betona avtomatska kontrola roboti linijski senzor povratna zanka posedanje materiala kompenzacija pozicije šobe 3D-printing of concrete automatic control robots line sensor feedback loop settling of material nozzle position compensation true false false [A.
