Abstract: The present invention provides a photosensitive adhesive comprising a composition of 0.1 portion to 1 portion by weight of photo initiator; 0.1 portion to 3 portions by weight of organic silicone; 10 portions to 32.5 portions by weight of isocyanate; 10 portions to 32.5 portions by weight of hydroxyethyl terminated polysiloxane; 10 portions to 32.5 portions by weight of polycarbonate diol; 5 portions to 17.5 portions by weight of hydroxyethyl acrylate; 0.01 portion to 0.5 portion by weight of catalyst; and 0.01 portion to 0.5 portion by weight of polymerization inhibitor.

Abstract: An apparatus and method for production of three-dimensional objects are disclosed. The apparatus comprises a reflective chamber (10), a plurality of electromagnetic radiation sources (35) adapted for providing electromagnetic radiation inside the reflective chamber (10), the plurality of electromagnetic radiation sources (35) mounted on inner walls of the reflective chamber (10). The method comprises the steps of placing a UV material on a model template or a transparent plate (51,52), setting of time value and light intensity of ultra violet light emitted from a plurality of electromagnetic radiation sources (35) and allowing the reflection of ultra violet light between a plurality of reflective layers inside the reflective chamber (10), solidifying the material inside the reflective chamber (10) after a period of time set out by control means and forming a three-dimensional object from the UV activated material on a model template or transparent plate (51,52).
