摘要： In a method for producing a three-dimensional object wherein the object is produced layer by layer by applying a layer of a material which can be solidified by irradiation with electromagnetic radiation and subsequently solidifying the layer at the points corresponding to the object by irradiation the problem is encountered that the production process is considerably delayed by long heating and cooldown times within the apparatus used for the production. According to the invention this problem is solved by irradiating and thereby solidifying in each layer a region of the material surrounding the object so as to produce a container wall (26) for the material (21).

摘要： A method and apparatus that decrease the time normally used in a high-pressure, high-temperature furnace for heating a material to be treated to a desired temperature prior to treatment and cooling that material to low temperatures after the treatment. The material is heated prior to insertion into the furnace and held within a thermally insulated container having a means of communicating with the hot zone of the furnace until insertion is desired and the normal treatment carried out. Subsequent to the treatment the material is again placed within the container and allowed to cool or possibly subjected to further thermal treatments within the container. The use of this holding apparatus allows greater utilization of the high-pressure, hightemperature furnace by freeing it from the function of routine heating and cooling of the treated materials.
摘要翻译：一种减少通常在高压高温炉中使用的时间的方法和装置，用于将待处理材料加热至所需温度，然后处理并将该材料冷却至处理后的低温。材料在插入炉内之前加热并保持在具有与炉的热区连通的装置的绝热容器中，直到需要插入并进行正常处理。在处理之后，将材料再次放置在容器内并允许冷却或者可能在容器内进行进一步的热处理。通过使用该保持装置，可以通过使高压高温炉从处理材料的常规加热和冷却的功能中获得更大的利用。

摘要： A recoating unit (40) serves for equipping or retrofitting a device (1) for additive manufacturing of a three-dimensional object (2) by selectively solidifying a building material (15), preferably a powder, layer by layer. The device (1) comprises a recoater (16) movable across a build area (8) for applying a layer (31b, 32b) of the building material (15) within the build area (8) and a solidification device (20) for selectively solidifying the applied layer (31b, 32b) at positions corresponding to a cross-section of the object (2) to be manufactured. The device (1) is formed and/or controlled to repeat the steps of applying and selectively solidifying until the object (2) is completed. The recoating unit (40) comprises at least two recoating rollers (41, 42) spaced apart from each other in a first direction (B1) and extending into a second direction transversely, preferably perpendicularly, to the first direction, and a compacting and/or smoothing element (45) arranged between the two recoating rollers (41, 42) in the first direction (B1) and extending into the second direction. The recoating unit (40) is adapted to draw-out building material to a regular layer (31a, 32a), depending on the movement of the recoating unit into the first direction (B1) or into its reverse direction (B2), using the recoating roller (41, 42) arranged ahead in the respective moving direction (B1, B2), and to compact or smoothen the layer (31a, 32a) drawn-out by the recoating roller (41, 42) arranged ahead using the compacting and/or smoothing element (45).

摘要： Lubricant composition and related methods and apparatus for manufacturing a green compact in a die cavity during a powder metallurgy operation wherein the lubricant composition includes a first component and a second component. The first component has a starting phase, an active phase, and a transition temperature at which at least part of the first component changes state from the starting phase to the active phase. Upon contact with wall surfaces of the die cavity, the first component transitions from the starting phase to the active phase, and the second component adheres to the active phase of the first component to form a lubrication layer coating the die wall surfaces. The component may be a first solid particulate component, such as polymeric particulate material or a sugar, or a first gaseous component, such as water vapor or palm oil vapor, respectively able to melt or condense upon contact with die cavity.

摘要： To improve the performance of a rare-earth magnet, it is effective to use a low-oxidized powder having a small grain size. One objective of the present invention is to provide a method for manufacturing a sintered rare-earth magnet having a magnetic anisotropy, in which a very active powder having a small grain size can be safely used in a low-oxidized state. Another objective is to provide a method capable of efficiently manufacturing products having various shapes. In a weighing and loading section 41 and a high-density loading section 42, a fine powder as a material of the sintered rare-earth magnet having a magnetic anisotropy is loaded into a mold until its density reaches a predetermined level. Then, in a magnetic orientation section 43, the fine powder is oriented by a pulsed magnetic field. Subsequently, the fine powder is not compressed but immediately sintered in a sintering furnace 44. The present method enables the mass-producing machine to be simple in its operation and its housing to be accordingly smaller, so that it will be possible to eliminate the danger of oxidization or burning of the powder, which has been a serious problem for a conventional method that uses a large-scale die-pressing machine. Furthermore, the manufacturing efficiency can be improved by using a multi-cavity mold for manufacturing a sintered rare-earth magnet having an industrially important shape, such as a plate magnet or an arched plate magnet.
