Provided herein is a resin product useful for the production of three-dimensional objects by additive manufacturing, and methods using the same. The resin may include a reactive blocked prepolymer comprising a prepolymer blocked with reactive blocking groups; a polyol; a photoinitiator; and at least one organometallic catalyst. A packaged product useful for the production of three-dimensional objects by additive manufacturing, the product comprising a single container having a single chamber and a resin in the chamber with all components mixed together, is also provided.

The present invention relates to a composition for a polymer electrolyte which includes a polymerizable oligomer capable of forming an excellent crosslink during a polymerization reaction. Also, the present invention relates to a polymer electrolyte, which may ensure high oxidation stability and ionic conductivity by using the composition for a polymer electrolyte, and a lithium secondary battery including the same.

The present invention pertains to a photocurable composition for a 3D printer for producing a transparent orthodontic device. A photocurable composition for a 3D printer can be provided, which has excellent physical properties such as thermal properties, strength, elastic modulus, and tensile elongation, and when used in a patient-customized transparent orthodontic device, the orthodontic device can reduce the pain felt by patients and can enhance orthodontic correction effectiveness due to being closely fitted to the dental structure. Moreover, a 3D-printed transparent orthodontic device can be produced which can be restored to the original shape thereof even when deformed from use.
