A tool allows a user to create new designs for apparel and preview these designs in three dimensions before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel. With the tool, the user will be able to create, make changes, and view images of a design, in real time, before burning by a laser. The tool can be accessed or executes via a Web browser.

A laser treatment system and method for imparting beneficial residual stresses into a desired part during production thereof by a Selective Laser Sintering or Melting (SLS/SLM) process, the method including repeatedly subjecting the part to an in-situ Laser Shock Peening (LSP) treatment during the SLS/SLM process. The in-situ LSP treatment includes selectively bringing an LSP module in contact with a surface of the part during the SLS/SLM process, and subjecting the LSP module to the action of a first laser beam to impart beneficial residual stresses into the part. The LSP module is movable between a building chamber where the part is being produced for the purpose of carrying out the in-situ LSP treatment, and a separate storage chamber when the LSP module is not used for the purpose of carrying out the in-situ LSP treatment. The invention is also implementable in a corresponding additive manufacturing system and method.

A method and device for producing a predetermined breaking line in a vehicle interior trim part with a scanning laser beam. An actual position of the vehicle interior trim part held in a working plane relative to a laser scanning device is detected by a camera and the actual position of the predetermined breaking line is derived. A stored desired position for a scan figure corresponding to the predetermined breaking line is corrected to an actual position, whereby the predetermined breaking line is produced at a predetermined position on the vehicle interior trim part during scanning of the scan figure. A positional shift of the scan figure becomes possible because a sensor matrix with an upstream diffuser is used, which can detect transmitted components of the laser beam independently of the position of the laser beam along the scan figure.

An ingot is processed by applying exciting light, and detecting fluorescence occurring from an upper surface of the ingot. A distribution of the number of photons of the fluorescence on the upper surface of the ingot is stored as two-dimensional data in association with XY coordinate positions, and a Z-coordinate position at which the two-dimensional data is obtained is also stored. A laser beam forms a peeling layer by irradiating the ingot while positioning the condensing point of the laser beam at a depth corresponding to the thickness of a wafer from the upper surface of the ingot. A wafer is separated from the ingot with the peeling layer as a starting point, and three-dimensional data is generated representing the distribution of the number of photons of the fluorescence in the whole of the ingot on the basis of two-dimensional data at each Z-coordinate position of the ingot.

A mask includes a mask sheet including an upper surface and a lower surface facing the upper surface, the mask sheet including an opening passing through the upper surface and the lower surface; and a mask frame that supports the mask sheet, the mask sheet includes a protrusion adjacent to the opening and protruding from the lower surface, and a recess adjacent to the protrusion and recessed from the lower surface toward the upper surface of the mask sheet.

Provided is a two-photon spectroscopy including a light source configured to generate first laser light having a pulse, a pulse width correction device configured to receive the first laser light to output a second laser light, an optical system through which the second laser light passes, a first two-photon sensor configured to measure a first pulse width of the first laser light generated from the light source, and a second two-photon sensor configured to measure a second pulse width of the second laser light passing through the optical system, wherein the pulse width correction device corrects a difference between the first pulse width and the second pulse width.

An additive manufacturing system may include an energy source, an optical system to modify and direct an energy beam from the energy source toward a component to form a melt pool, and a material delivery device to deliver material to the melt pool. The optical system may form an annular energy beam, direct the annular energy beam toward the component, receive at least a portion of thermal emissions produced by the annular energy beam and the melt pool, and direct the portion of the thermal emissions toward an imaging device, which may be used to control the energy source.

The present disclosure relates to an apparatus for additively manufacturing a product in a layer-by-layer sequence, wherein the product is formed using powder particles deposited on an interface layer of a substrate. A laser generates first and second beam components. The second beam component has a higher power level and a shorter duration than the first beam component. A mask creates a 2D optical pattern in which only select portions of the second beam components can irradiate the powder particles. The first beam component heats the powder particles close to a melting point, where the particles experience surface tension forces relative to the interface layer. While the particles are heated, the second beam component further heats the particles and also melts the interface layer before the surface tension forces can act on and distort the particles, enabling the particles and the interface layer are able to bond together.
