The present invention lies in the field of 3D printing methods. In particular, the invention relates to 3D printing methods for the production of a 3D part in a layer-by-layer manner, wherein the printable composition is a pasty epoxy composition comprising at least one epoxy resin, at least one monomer and/or prepolymer that is polymerizable by exposure to radiation and at least one photoinitiator, wherein the pasty epoxy composition has a viscosity factor (1.5/15) of at least 2 at application temperature.

Dual cure epoxy formulations for 3D printing applications

The present invention lies in the field of 3D printing methods. In particular, the invention relates to 3D printing methods for the production of a 3D part in a layer-by-layer manner, wherein the printable composition is a pasty polyurethane composition comprising at least one polyisocyanate resin, at least one monomer and/or prepolymer that is polymerizable by exposure to radiation and at least one photoinitiator, wherein the pasty polyurethane composition has a viscosity factor (1.5/15) of at least 2 at application temperature.

Dual cure polyurethane formulations for 3D printing applications

The present application relates to a thermally expandable composition containing at least one peroxide cross-linking polymer, at least one peroxide and at least one endothermic, chemical blowing agent, the blowing agent comprising at least one solid, optionally functionalized, polycarboxylic acid or the salt thereof and at least one urea derivative according to the formula (I) as defined herein; as well as shaped bodies containing the composition and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components using shaped bodies of this type.

Thermally expandable compositions comprising urea derivatives

A thermally expandable composition that comprises at least one organic compound having at least one cyclic carbonate group as a blowing agent, at least one catalyst for the blowing agent, at least one reactive binder and at least one hardener and/or accelerator. Also provided are molded bodies containing the composition, and a method for sealing and filling hollow spaces in components, in order to strengthen or stiffen components, in particular hollow components, and for adhering movable components through use of molded bodies of this type, as well as to the use of corresponding cyclic organic carbonates as a blowing agent in thermally expandable compositions.
