A method for producing a roof tile having a water barrier, wherein the water barrier is shaped onto a roof tile blank, which is supplied onto a lower mould, of a shaping unit, with a shaped piece and a shaping stamp that can move in relation to same. The shaped piece is placed on an upper side of a top end of the roof tile blank, and the shaping stamp is pressed against the top end of the roof tile blank, such that material of the roof tile blank is pressed into a shaping mould of the shaped piece. The roof tile blank is also arranged below the shaping unit and the shaping unit is vertically lowered onto the roof tile blank. The invention also relates to a roof tile produced according to this method having a water barrier shaped thereon.

Methods and devices for modifying a building panel are disclosed. A solution is applied to a surface of the building panel. The solution consists of light alcohols. A force is applied to a portion of the building panel substantially normal to a horizontal plane of the panel. The force causes a deformation of the portion of the building panel.

A method for producing a thin-walled metal part with complex geometry includes mixing a metal powder with a polymer binder in order to obtain a composite mixture, producing a flexible composite sheet from the composite mixture, cutting, in the flexible composite sheet, a preform based on a contour of the metal part, applying the preform in a mold having a surface configured with a relief of the metal part, and debinding and sintering the preform in order to obtain the metal part.

A system and a method for constructing a printed ceramic object, the method including the steps of extruding a substance to generate a 3D-printed elastomeric object; deforming the 3D-printed elastomeric object into a complex structure to form a printed elastomeric origami object; and transforming the printed elastomeric origami object into an aforesaid printed ceramic origami object.

A system and method of constructing a 4D-printed ceramic object includes extruding inks including particles and polymeric ceramic precursors through a nozzle to deposit the inks on a heating plate, whereby a 3D-printed elastomeric object is formed on the heating plate, folding the 3D-printed elastomeric object into a complex structure to form a 4D-printed pre-strained elastomeric object, and converting the 4D-printed elastomeric object into the 4D-printed ceramic object.

A fixture for processing a ceramic matrix composite article includes first and second tool segments that each have an exterior side and an interior side. The tool segments define there between a working region for holding a fiber preform that is to be densified with a ceramic material. Each of the interior sides has grooves there along for delivering a precursor gas to the working region.

A ceramic wafer includes an upper surface and a lower surface, and the ceramic wafer includes at least one curved surface. A manufacturing method of the ceramic wafer includes the steps of: performing a high-temperature sintering process on a ceramic green body to produce a ceramic material; and performing a processing process on the ceramic material to form the ceramic wafer, wherein the processing process is used to change the shape of the ceramic material and thereby form the ceramic wafer. The ceramic wafer and the manufacturing method thereof are advantageous in that by forming a warped or bowed ceramic wafer, it is made possible for the surface tension or surface internal stress resulting from forming a thick integrated circuit film on the ceramic wafer to pull the ceramic wafer into a relatively flat configuration suitable for subsequent manufacturing processes that require wafer flatness.
