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： A method of forming a ferrous metal case-hardened layer using additive manufacturing. The method includes delivering, by a material delivery device, a filler material to a surface of a substrate. The substrate includes a first ferrous metal. The filler material includes a second ferrous metal and a carbon-based material. The method also includes directing, by an energy delivery device, an energy toward a volume of the filler material to join at least some of the filler material to the substrate to form a component.

摘要： An example laser tool is configured to operate within a wellbore of a hydrocarbon-bearing rock formation. The laser tool includes one or more optical transmission media. The one or more optical transmission media are part of an optical path originating at a laser generator configured to generate a laser beam having an axis. The one or more optical transmission media are for passing the laser beam. The laser tool includes an optical element that is part of the optical path. The optical element is for receiving the laser beam from the one or more optical transmission media and for output to the hydrocarbon-bearing rock formation. The laser tool includes a color applicator head for discharging one or more coloring agents to a surface in the wellbore in a path of the laser beam.

摘要： A device for the making of a three-dimensional object by means of layer by layer consolidation of a powderlike construction material by electromagnetic radiation or particle beam has a control unit that controls an irradiation device such that the powder particles of the construction material are bonded together at the sites where the radiation impinges on the construction material. A selective heating device is designed so that any given partial surface of the construction field can be heated before and/or after to a plateau temperature, which is significantly higher than the temperature of at least a portion of the construction field outside the partial surface. The control unit actuates the selective heating device such that the partial surface has a predefined minimum distance from the edge of the construction field.

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： A direct metal laser melting (DMLM) system includes a rotatable base, and a build plate mounted on and supported by the rotatable base, where the build plate includes a build surface. The DMLM system also includes a first actuator assembly, a first powder dispenser disposed proximate the build plate and configured to deposit a weldable powder on the build surface of the build plate. In addition, the DMLM system includes a first powder spreader disposed proximate the build plate and configured to spread the weldable powder deposited on the build surface of the build plate, and a first laser scanner supported by the first actuator assembly in a position relative to the build plate, such that at least a portion of the build surface is within a field of view of the first laser scanner. The first laser scanner is configured to selectively weld the weldable powder. The first laser scanner is further configured to translate axially relative to the build surface on the first actuator assembly.

摘要： Methods and tools for manufacturing reinforced structural components are described. The methods comprise providing a structural component having a steel substrate and a metal coating layer. The method further comprises selecting a reinforcement zone of the structural component, guiding a first laser beam to ablate at least a part of the coating layer of the reinforcement zone, locally depositing a reinforcement material on the ablated reinforcement zone to create a local reinforcement on a first side of the structural component, wherein locally depositing a material on the reinforcement zone comprises supplying a reinforcement material to the ablated reinforcement zone, and substantially simultaneously applying laser heating using a second laser beam to melt the reinforcement material and part of the steel substrate of the ablated reinforcement zone to mix the melted reinforcement material with the melted part of the steel substrate. The disclosure further relates to reinforced components obtained using such methods.

摘要： An apparatus and method for additive manufacturing a metal part having portions with varying microstructures. The method may include depositing an additive manufacturing powder on a surface and melting or sintering a first portion of the additive manufacturing powder while it is covered with a first type of cover gas. Next, the method may include melting or sintering a second portion of the additive manufacturing powder while it is covered with a second type of cover gas. The first portion may be a first layer of the additive manufacturing powder and the second portion may be a second layer of the additive manufacturing powder deposited after melting or sintering of the first layer. Additionally or alternatively, the first portion and the second portion may both include distinct portions of a single layer of the additive manufacturing powder.
