Titolo originale Additive manufacturing of SiOC glass with the UV Assisted-Direct Ink Writing technique
Titolo inglese Additive manufacturing of SiOC glass with the UV Assisted-Direct Ink Writing technique
Abstract in italiano The UV Assisted-Direct Ink Writing is an AM hybrid technique wich was used to realize SiOC ceramic structures starting from preceramic polymers. Suspended and self supporting structures able to mantain their designed shape were printed and after the thermal treatment of pyrolysis at 1000°C the samples showed a linear shrinkage without cracks on the surfaces. The designed inks were characterized from the rheological point of view and with regard to printability and the green samples were analyzed with FTIR and thermal analysis. The density, the shrinkage, the crystallinity, mechanical properties and surface aspect of pyrolyzed samples were also studied.
