A composite forming apparatus includes an end effector, a forming feature, and a non-contact heater. The forming feature is coupled to the end effector. The end effector moves the forming feature relative to a composite ply to form the composite ply over a forming tool or a prior formed composite ply. The non-contact heater heats to a portion of the composite ply before the portion of the composite ply is formed over the forming tool or the prior formed composite ply.

The present invention concerns type II photoinitiators for the free-radical crosslinking of silicone compositions, in particular acrylic silicone compositions.

A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.

The invention relates to a method for producing an intraocular lens, including the steps of providing a container which is transparent to electromagnetic radiation and in which a liquid that is curable by the electromagnetic radiation is arranged; irradiating the liquid with a set of images formed by the electromagnetic radiation, which each depict an intraocular lens, with each of the images of the set being radiated into the liquid at a different angle of incidence with respect to a reference plane that extends through the liquid, as a result of which the liquid is cured and the cured liquid forms the intraocular lens, an actuator, a solar module and/or a sensor being arranged in the liquid and the intraocular lens being formed around the actuator, the solar module and/or the sensor.
