LINE LASER IMAGER FOR THERMOPLASTIC SELECTIVE LASER SINTERING
20170361530 · 2017-12-21 ·

A method for printing an object using a high power one-dimensional (1D) line laser imager for selective laser sintering of thermal plastics. The technique is a two-step process. First, a layer of fresh powder is deposited on top of an existing powder bed. Second, the powder is sintered with the line laser print head. The laser is modulated at the source or with a spatial light modulator. Multiple passes or imagers can be used for increased part width and productivity. Using the relative travel between energy receiving surface and the laser print head in the direction perpendicular to the laser imaging line, a 2D pattern is imaged. Multiple print head can be aligned and joined to form a wider laser print head.

Further, such particle comprises at least one wall separating a first void and a second void contained between the first side and the second side, while the wall has a width ranging from 0.01 mm to 5 mm as measured in a cross sectional plane.

Method and apparatus for producing three-dimensional objects

An apparatus and a process for manufacturing a three-dimensional object by successive layer-by-layer consolidation of selected zones of a powder stratum, the consolidated zones corresponding to successive sections of the three-dimensional object, each layer being divided into a central internal portion and an external border, said process comprising the following steps in order: a—depositing a powder layer on a holder; b—fusing the external border of said powder layer by means of a laser beam originating from a first energy source by moving the laser beam of said first energy source relative to the object along a preset path that follows the contour of said external border corresponding to the contour of the cross section of the object so as to selectively fuse said layer; and c—fusing the central internal portion of the powder layer by means of an electron beam originating from a second energy source, by moving the electron beam of said second energy source relative to the object so as to sweep it over said central internal portion along a preset path corresponding to the central internal portion of the cross section of the object so as to selectively fuse said layer; or d—repeating steps a and b N times so as to form a plurality of superposed layers of fused material forming a portion of the external border of said object and then carrying out step c so as to fuse the central internal portion of the object corresponding to the N powder layers; and e—repeating steps a to c or a, b and d until all the layers of the object have been consolidated.
