Abstract: The invention relates to the use of a printing sol as construction material in an additive manufacturing process for producing a 3-dim article, the printing sol comprising solvent(s), nano-sized crystalline zirconia particles in an amount from 2 to 25 vol.-% with respect to the volume of the sol, the average primary particle size of the nano-sized crystalline zirconia particles being in a range up to 50 nm, a first monomer being a polymerizable surface modification agent represented by formula A-B, with A being capable of attaching to the surface of the nano-sized crystalline zirconia particles and B being a radiation curable group, optionally a second monomer, the second monomer comprising at least one radiation curable moiety but no acidic or silane group(s), photo initiator(s). The invention also relates to a ceramic article obtainable according to such a process.

Abstract: The present invention relates to a process for producing a ceramic article, the process comprising the steps of providing a printing sol, the printing sol comprising solvent, nano-sized particles, radiation curable monomer(s) and photoinitiator, the printing sol having a viscosity of less than 500 mPa*s at 23° C., processing the printing sol as construction material in an additive manufacturing process to obtain a 3-dim article being in a gel state, the 3-dim article having a Volume A, transferring the 3-dim article being in a gel state to a 3-dim article being in an aerogel state, heat treating the 3-dim article to obtain a sintered 3-dim ceramic article, the ceramic article having a Volume F, Volume A of the 3-dim article in a gel state being more than 500% of Volume F of the ceramic article in its sintered state. The invention also relates to a ceramic article obtainable according to such a process. The ceramic article can have the shape of a dental or orthodontic article.

Abstract: Web-wound rolls with a web edge treatment by printable adhesive compositions and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more quantities of adhesive are disposed and subsequent curing adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the adhesive.
