20.500.12556/RUL-160504 Tuning the rheological properties of paraffin-wax ceramic feedstocks for deposition with thermoplastic 3D printing Droplet deposition with material-jetting methods such as thermoplastic 3D printing (T3DP) depends greatly on the rheological properties of the feedstocks. This study investigated the effect of particle interactions and the degree of weak flocculation on the shear thinning behaviour, the yield stress and the storage/loss moduli of paraffin-wax-based feedstocks containing 40 vol% of zirconia (3Y-TZP) micron-sized powder. Steric stabilization of the feedstocks was provided by varying the ratios of the surfactants with different chain lengths, i.e., stearic acid (2.4 nm) and Solsperse 3000® (10 nm), which in turn affected the dynamics of the droplet formation and the quality of the layers when jetting non-Newtonian, thermoplastic ceramic feedstocks. The results of the study extend the guidelines for the processing of printable feedstocks used in T3DP additive manufacturing. additive manufacturing material jetting colloidal processing zirconia rheology true false true Angleški jezik Ni določen Članek v reviji 2024-08-29 10:33:28 2024-08-29 10:33:32 2024-08-31 03:50:35 0000-00-00 00:00:00 2024 0 0 Str. 7791-7800 iss. 13 Vol. 44 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1/.2 1873-619X 10.1016/j.jeurceramsoc.2024.05.057 205598211 1-s2.0-S095522192400476X-main.pdf 1-s2.0-S095522192400476X-main.pdf 1 348F2AA62CAF6199D77C3E7B3E71BB2E 78ae8de876f5f39fee40d430a24f61ebda2f6b9038c617e36b5e8521c317ad4a a5270ef4-65e1-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189209 https://www.sciencedirect.com/science/article/pii/S095522192400476X 1 24fd6181-65e1-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189208 Fakulteta za strojništvo 0 0 0
