Abstract: A scanning laser having a wavelength compatible with a coating binder so as to cure it as the laser scans and irradiates the coating on a moving web. A system and method for curing flakes by providing a scanning laser which scans across a moving coated substrate in a magnetic field allows images to be formed as magnetically aligned flakes are cured into a fixed position.

Alternatively an array of lasers can be used wherein individual lasers can be switched on and off to fix irradiated coating as a moving web is moved at a high speed.

Abstract: In the additive manufacturing process, a monitored or controlled mixture of materials is deposited to form an additive manufactured product by delivering the mixture of materials through a material flow path while using an excitation source to introduce electromagnetic energy into the material flow path using a circuit element having inductive or capacitive reactance disposed adjacent the material ejecting orifice. The excitation source produces an electromagnetic field condition within the material flow path that is responsive to at least one of the permeability and permittivity properties of a space within the material flow path. A sensing means coupled electrically or magnetically to the excitation means is responsive to the electromagnetic field condition and provides at least one control parameter based on the electromagnetic field condition that may be used to control the composition of the mixture of materials by adjusting proportions of constituent materials.

Abstract: A composition for forming film having wrinkle structure and a method of forming the film are disclosed. The composition includes photo-curable agent and photoinitiator dissolved in the photo-curable agent. The cut off wavelength of light transmittance of the photo-curable agent is greater than the cut off wavelength of light absorbance of the photoinitiator. Photo-cured thin film is formed at the upper portion of composition layer at an initial time period of irradiation. By subsequent contraction, the photo-cured thin film forms wrinkles. The wrinkle structure is controlled by the relation of the cut off wavelength of light transmittance of the photo-curable agent and the cut off wavelength of light absorbance of the photoinitiator, the photo-curing rate of the composition and the thickness of the composition layer, and the photoinitiator concentration, etc., before photo-curing. The film may increase the emission efficiency of LED and OLED and the sensing effect of sensor.
