摘要： An apparatus for forming an integral three-dimensional object from a plurality of individual laminations includes a cutting surface on which each of the laminations is individually deposited. A concentrated energy source cuts each of the plurality of laminations into a shape required for assembly of the laminations into the integral three-dimensional object. A transfer mechanism removes each of the cut laminations from the cutting surface and stacks each of the cut laminations on an assembly surface. The transfer mechanism includes a gripper face having a peripheral portion and a central portion. A mask is positioned on the gripper face. The mask has an apertured central portion corresponding to the cut lamination. A source of suction communicates with the gripper face and a valve mechanism selectively draws a suction on the gripper face peripheral portion, the gripper face central portion, both or neither. An electronic control device is provided for controlling the operation of the cutting surface, the concentrated energy cutter and the transfer mechanism.

摘要： A method for manufacturing an integral three dimensional object from laminations includes the steps of fabricating a plurality of first sheets of a first material composition, cutting each of the first sheets to form a contoured layer representing a cross-section of the three dimensional object and to form a waste material and discarding the waste material. The contoured layers are stacked in a desired sequence to form a stack of contoured layers which are then laminated. Subsequently, the contoured layers of the stack are secured to each other to form the integral three dimensional object. This method works particularly well with ceramic material sheets. If desired, a second type of sheet made of a fugitive material can also be cut to form a contoured layer representing a void in a cross-section of the three dimensional object. The contoured layers of the second sheets are then stacked along with the contoured layers of the first sheets to form the object. The laminated stack of contoured layers is then sintered. During processing, fugitive material can be removed, leaving voids in the three dimensional object.
摘要翻译： 一种用于从叠片制造整体三维物体的方法包括以下步骤：制造多个第一材料组合物的第一片材，切割每个第一片材以形成表示三维物体的横截面的轮廓层， 形成废料并丢弃废料。 轮廓层以期望的顺序堆叠以形成叠层的轮廓层，然后层压。 随后，堆叠的轮廓层彼此固定以形成整体的三维物体。 该方法与陶瓷材料片特别适用。 如果需要，还可以切割由缓冲材料制成的第二类型的片材，以形成表示三维物体的横截面中的空隙的轮廓层。 然后将第二片的轮廓层与第一片的轮廓层一起堆叠以形成该物体。 然后将成型层的层叠叠层烧结。 在处理过程中，可以去除短暂的物质，在三维物体中留下空隙。

摘要： The sealing of the gas path in a gas turbine engine at the blade tips is improved by maintaining a minimum clearance between the rotor blade tips and the gas path seal. This is accomplished by taking advantage of an increase in volume during controlled oxidation of certain intermetallic compounds which have high melting points.The increase in volume closes the clearance subsequent to a rub between the blades and the seal. Thus, these compounds re-form the tip seal surface to assure continued engine efficiency.

摘要： In a process for producing powder metallurgy objects containing two or more individually formed pieces, the individual formed pieces or powder compacts which are comprised of powder and a binder are joined together. A polymer compatible with the binder is sandwiched between two such powder compacts. A lamination joint is formed. The polymer is then softened, and a resultant aggregate body is thermally processed to remove the binder and polymer. The resulting object has no residual interface between the original individually formed pieces. There is no discernable boundary at the lamination joint. The final part is homogeneous and uniform with no foreign material or structural imperfections at the joint.
