Provided herein are curable compositions useful for, among other things, making three-dimensional parts by additive manufacturing. The compositions when cured exhibit a surprising balance of improved tensile strength and percent elongation.

Curable compositions

Methods for manufacturing three-dimensional articles having reduced surface haze, by applying a coating to the surface of a three-dimensional article made by additive manufacturing are described.

Three-dimensional articles made by additive manufacturing having reduced surface haze

Provided herein are methods for making three-dimensional parts by additive manufacturing using a debondable curable coating composition on the build surface.

Three-dimensional parts made by additive manufacturing using a coating composition on the build surface

Photocurable (meth)acrylate compositions with low viscosity when uncured, and high flexibility and shear/tensile strength when cured, further possessing rapid tack-free fixture times, comprising mixtures of urethane acrylate resin, isobornyl acrylate, N,N-dimethylacrylamide, a photoinitiator component, and a low percentage of tetrahydrofurfuryl acrylate, for example from about 9% to about 15% by weight based on the weight of the composition. Applications can include adhesive bonding of medical tubing, UV/Visible transparent plastics material medical devices or equipment, or other flexible UV/Visible transparent material substrates.
