摘要： A binder jet printed article includes a part having a top portion, a bottom portion, and an overhang extending from the top portion and a support structure formed around the part that may block deformation of the part during post-printing thermal processing. The support structure includes a skid positioned adjacent to the bottom portion that may support the part, a first plurality of support features disposed along an outer perimeter of the skid, and a second plurality of support features disposed on the top portion of the printed part. The first and second plurality of support features form a lattice around the printed part such that the printed part is nested within the support structure.

摘要： A manufacturing line includes a tape of green material that is directed through a furnace so that the furnace burns off organic binder material and then partially sinters the tape without the use of a setter board. Sintered articles resulting from the manufacturing line may be thin with relatively large surface areas; and, while substantially unpolished, have few sintering-induced surface defects. Tension may be applied to the partially sintered tape as it passes through a second furnace on the manufacturing line to shape resulting sintered articles. The furnace is preferably vertically oriented and is operated preferably continuously. Preferably ceramic materials are used for forming the tape.

摘要： A method for firing a ceramic honeycomb body including heating a green ceramic honeycomb body from a first temperature to a second temperature at a first heating rate and at a first oxygen level. Then, the green ceramic honeycomb body is heated from the second temperature to a third temperature at a second heating rate and at a second oxygen level. In this firing schedule, the second heating rate is greater than the first heating rate, and the second oxygen level is greater than the first oxygen level. Further, oxygen is introduced into the kiln to increase an oxygen level of the kiln from the first oxygen level to the second oxygen level near a peak of organic volatile release.
