摘要： Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform.

摘要： Disclosed herein is a film cutting system for dividing and forming a film sheet having a predetermined unit width and unit length from a raw film by laser cutting of the raw film. The film cutting system includes: a supply unit configured to intermittently supply the raw film by a predetermined unit supply length in a length direction of the raw film; a first laser unit including first and second laser nozzles each configured to radiate a laser beam onto the raw film, and a first head driver configured to convey the first laser nozzle and the second laser nozzle in a width direction of the raw film perpendicular to the length direction in a reciprocating manner; and a second laser unit including a laser nozzle disposed spaced apart from the first laser unit by the unit length in the length direction and configured to radiate a laser beam onto the raw film, and a second head driver configured to convey the laser nozzle in the width direction in a reciprocating manner, wherein, when the raw film is supplied by the supply unit, the first head driver dispose the first laser nozzle and the second laser nozzle so as to be spaced apart from each other by the unit width, and each of the first laser nozzle and the second laser nozzle radiates, in the length direction, the laser beam onto the raw film supplied by the supply unit to slit the raw film, and wherein, when the slitting of the raw film is completed, the supply unit stops supplying the raw film; the first head driver conveys one of the first laser nozzle and the second laser nozzle in the width direction; the second head driver conveys the laser nozzle in the width direction; and the one of the first laser nozzle and the second laser nozzle and the laser nozzle respectively radiate the laser beam onto the raw film in the width direction to cut the raw film to divide and form the film sheet from the raw film.

摘要： A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

摘要： An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects. A side removal mechanism of the build chambers of the apparatus improves handling and efficiency for printing large and heavy objects. Use of a wide range of sensors in the apparatus and by the method allows various feedback to improve quality, manufacturing throughput, and energy efficiency.

摘要： The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

摘要： A method for producing a diffusion-optimized tipping paper for tobacco products, especially filter cigarettes, by plasma perforation of the web of tipping paper for the purpose of maximum carbon monoxide reduction, wherein the diffusivity and the permeability P of the perforated tipping paper are measured in-line and diffusivity is maximized by controlling the perforation parameters, the definable target permeability Psoll being maintained at all times.

摘要： With a method of cutting a tube glass (G1) according to the present invention, the tube glass (G1) is irradiated with laser light (L) having a focal point (F) adjusted to an inside of the tube glass (G1), to thereby form an inner crack region (C1) including one or more cracks in a portion of the tube glass (G1) in a circumferential direction of the tube glass (G1) through multiphoton absorption that occurs in an irradiation region of the laser light (L). Then, in the tube glass (G1), there is generated a stress that urges the one or more cracks in the inner crack region (C1) to propagate in the circumferential direction of the tube glass (G1) to cause the one or more cracks to propagate throughout an entire circumference of the tube glass (G1), to thereby cut the tube glass (G1).

摘要： A closure device for a chamber housing a laser units for cutting a sheet metal strip includes, in proximity of an exit slit of the strip to be machined, a bar arranged transversely to the axis of advancement of the strip, and having, at the lower edges of the major side surfaces, longitudinal edges of a U-folded plate bound thereto. The plate has a plurality of transverse slots ending before its edges. An actuator provided for a vertical movement of the bar.

摘要： An apparatus and method are described that use a cylindrical drum type vacuum drum and allows accurately registered, high resolution laser patterning of thin films on discrete lengths or flexible substrate material that are unwound from an unwind reel and after processing are rewound onto a rewind reel. Length compensator units are provided either side of the drum to accommodate variations in the length of the substrate due to differential rotation of the drum and the unwind and rewind reels.

摘要： A method for manufacturing metal strip comprises abutting at least two metal strips to form a abutment interface between each other, then welding the metal strips along the abutment interface by a laser light to form a weld pass with a welding penetration depth between the metal strips, and a reflected light is reflected from the weld pass, and finally receiving the reflected light by a spectrometer which can determine the welding penetration depth according to the reflected light spectrum. A welding parameter can be selectively adjusted according to the welding penetration depth to correct the welding penetration depth in real time, and the follow-up weld pass can conform to the specification for decreasing weld defective ratio.
