V raziskavi v okviru diplomskega dela smo pripravili različne mešanice lesnega prahu in PLA polimera, iz katerih smo izdelali filamente za 3D tiskanje z različnimi deleži lesa: z 10 %, 20 %, 30 %, 40 %, 50 %. Poleg tega smo uporabili dva komercialna filamenta z lesom: Laywoo-D3 in Primawood in dva filamenta brez lesnega prahu: PLA in ABS. Na 3D tiskalniku Zortrax M200 smo iz filamentov natisnili preskušance dimenzij 40 x 12 x 4 mm, ki smo jim z reometrom ARES G2 določili reološke lastnosti. Iz meritev smo določili modul elastičnosti, mejo linearno viskoelastičnega področja (LVR) in temperaturo steklastega prehoda materiala. Ugotovili smo, da se modul elastičnosti zmanjšuje z večanjem deleža lesa v filamentu in doseže minimum pri filamentu s 50 % deležem lesa. Med deformacijo na meji LVR med našimi filamenti ni bilo velikih razlik. Najnižjo deformacijo na meji LVR je dosegel filament s 50 %, najvišjo pa filament z 20 % deležem lesa. Temperatura steklastega prehoda je bila pri naših materialih podobna, to je 66 °C, zato ker so imeli filamenti isti osnovni polimer PLA.

Sekundarni naslov: Relevant properties of wood polymer mixtures for 3D printing technology
Sekundarni povzetek: In our research we prepared different mixtures of wood powder and PLA polymer. From these mixtures we prepared filaments for 3D printing with different content of wood in each filament. We made filaments with 10 %, 20 %, 30 %, 40 % and 50 % of wood powder in mixtures. We also include commercial filaments Laywoo-D3 and Primawood and filaments without wood, PLA and ABS. We used 3D printer Zortrax M200 to print our test models dimensions 40 x 12 x 4 mm. We were testing them on Rheometer ARES G2. We got results and we focused on Amplitude sweep and Temperature sweep. From these measurements we focused on storage modulus, LVR limit and glass transition temperature. The storage modulus was decreasing when percentage of wood was increasing in filament. So in our case minimum storage modulus have materials with 50 % wood powder. There was not a big difference between materials in deformation at LVR limit; the lowest deformation at LVR limit had filament with 50 % of wood powder and the highest had filament with 20 % wood powder. Glass transition temperature was in our case the same for all filaments (66 °C). They had the same glass transition temperature because they were made from the same base material-PLA.
