Abstract: A radiation curable composition including at least one radiation hardenable component, a photo-initiator, and a filler material having a population of particulates in an amount greater than or equal to 50% by weight of the printable composition. The population of particulates exhibits a median diameter (D50) of greater than or equal to 0.3 micrometer on a volume-average basis as determined using the Particle Size Test Method, and the radiation curable composition exhibits a viscosity of less than or equal to 150 Pa s when measured using the Viscosity Test Method. A method, apparatus, and systems for producing composite articles by selectively exposing a portion of the radiation curable composition to a source of actinic radiation to at least partially cure the exposed portion of the radiation curable composition, thereby forming a hardened layer, preferably by an additive manufacturing process such as stereophotolithography, are also described. The composite articles may include composite dental restorations.

Abstract: A radiation curable polyurethane resin includes an ionic group, a polyalkylene oxide in a side chain thereof, and a (meth)acrylate or (meth)acrylamide having a hydroxyl functional group. The polyurethane resin is obtainable by reacting a polyester polyol, a polyether diol, a polyol containing an ionic group, a (meth)acrylate or (meth)acrylamide having a hydroxyl functional group, and a polyisocyanate. The polyester polyol is obtained by reacting a polycarboxylic acid and a polyol. The radiation curable polyurethane resin can be used as binder in an aqueous ink jet ink.

Abstract: Disclosed methods include formulating azobenzene-based polymer networks to induce a modulus change in a highly crosslinked polymer, in vivo, with no external heat requirement and using a benign light as the source of stimuli. A modulus change can be achieved via a coating on the substrate and within the bulk of the substrate via photoexposure. The azobenzene-based polymer network can be formed as a coating or in the bulk of a material from either a glassy composition comprising methyl methacrylate (MMA), poly (methyl methacrylate) (PMMA), and triethylene glycol dimethacrylate (TEGDMA) or a soft material comprising of long-chain difunctional acrylates. The disclosed technology also includes methods of biofilm disruption and removal from the surface of a substrate, and includes methods of inhibiting biofilm growth and cell attachment to a substrate.
