Methods of printing a three-dimensional object using co-reactive components are disclosed. Thermosetting compositions for three-dimensional printing are also enclosed.

The present invention relates to core-shell particles comprising a core comprising at least one lipophilic compound and a shell comprising at least one layer close to the core and one layer far from the core. The invention further relates to the preparation of such core-shell particles and their use, particularly in the finishing of fibers and textiles.

The present invention relates to core-shell capsules prepared with linear and/or branched and cyclic aliphatic polyisocyanates. In particular, the present invention discloses a core-shell capsule, wherein the shell comprises or consists of a polymeric material which is produced or producible by reacting two components, the first component comprising or consisting of at least one linear aliphatic polyisocyanate and/or at least one branched aliphatic polyisocyanate having more than one isocyanate group, respectively, and at least one cyclic aliphatic polyisocyanate having more than one isocyanate group, the second component comprising or consisting of one or more crosslinking agent(s). Furthermore, a product comprising the present core-shell capsule, a process for producing the present core-shell capsules and the use of the present core-shell capsules is provided.

Provided herein are methods of recycling additively manufactured objects, which may include making a reactive particulate material by recycling preformed articles or recovered coating material. Methods of use of the reactive particulate material and material sets including the same are also provided.
