A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid including a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

Bonding dissimilar materials of medical device components can be carried out by applying an adhesive on at least one surface of two components which are composed of dissimilar materials and contacting the surfaces and exposing the contacted surfaces to heat and/or irradiate the adhesive to cure the adhesive and bond the surfaces. One medical component, e.g., medical tubing, can be composed of a non-polar, polyvinyl chloride free thermoplastic polymeric material and the other medical component, e.g., a medical connector, can be composed of polyacrylate, polyacrylonitrile, acrylonitrile-butadiene-styrene (ABS), methyl methacrylate-acrylonitrile-butadiene-styrene (mABS), polyester, and/or a polycarbonate material. The adhesive formulation can include: (a) a polyolefin oligomer having reactive acrylate groups and alkenyl groups, (b) an initiator, and optionally (c) a solvent.

An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.
