Abstract
V magistrskem delu izvedemo nadgradnjo DLP stereolitografskega tiskalnika, ki deluje na principu zamreženja fotopolimerne smole s pomočjo ultravijolične (UV) svetlobe iz DLP- projektorja. Pri preciznih izdelkih je veliko faktorjev, ki lahko vplivajo na kakovost tiska. Zagotovili smo mešanje smole na dnu bazena po izdelavi vsakega sloja. Zasnovali in izdelali smo novo izdelovalno platformo, na kateri gradimo izdelek, izdelali sistem za filtriranje zraka, nadgradili programsko in strojno opremo za krmiljenje perifernih enot tiskalnika in izdelali nekatere njegove funkcionalne komponente. Izvedli smo enostavni test izdelave, s katerim smo določili ponovljivost tiskanih izdelkov, ki znaša 34 µm v x-smeri, 70 µm v y-smeri in 146 µm v z-smeri (95 % meja zaupanja). Pri tem je bila višina sloja 75 µm.

Title:Upgrade of the DLP stereolithography printer
Abstract:
In this master thesis, we upgraded a DLP stereolithography printer that works on the principle of crosslinking a photopolymer resin using ultraviolet (UV) light from a DLP-projector. For precise products, there are many factors that can affect the quality of the print. We provided mixing the resin at the bottom of the pool after the production of each layer. We designed and made the new build platform on which we were building the product, made an air filtration system, upgraded the software and hardware for controlling the peripheral units of the printer, and made some of its functional components. We carried out a simple test to determine the repeatability of printed products, which is 34 μm in the x-direction, 70 μm in the y-direction and 146 μm in the z-direction (95% confidence limit). The height of the layer was 75 μm.

Keywords:stereolithography, digital light processing, 3D-printing, photopolymer, control
