Abstract: An apparatus and method for stamping a thermoplastic matrix composite blank, in view of heating and stamping the blank. The apparatus includes a machined blank and a frame. A plurality of cleats are fixed on the frame, extend towards the interior of the frame. The cleats delimit an internal opening surface of the frame, free from any obstacle. A locator is linked with a cleat and configured to cooperate with a hole machined in the blank. A heat sink is located near the locator and configured to maintain locally the blank temperature under the melting temperature of the polymer constituting the matrix, during the heating and transfer of the blank.
Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. Either a build platform or a solidification substrate has a curved surface, and each point on the curved surface traverses a trochoidal path during an object solidification operation. The curved surface allows the separation forces between the solidification substrate and the most recently solidified layer of material to be concentrated along a line instead of along a planar section which reduces the overall separation force and the likelihood of damaging a part.

Abstract: A three-dimensional printing apparatus and a method for calibrating printing inaccuracy thereof are provided. A printing head of the three-dimensional printing apparatus is adapted for moving along a straight printing path on a datum plane and simultaneously feeding out forming material, so as to generate a layer object on a supporting surface of a platform. If a path distance of the straight printing path is greater than a threshold, a plurality of linear compensation relationships respectively corresponding to a plurality of first zones of the supporting surface are used for calculating a first compensation value of a starting point and a second compensation value of an ending point. If the path distance of the straight printing path is not greater than the threshold, a common compensation values is decided based on at least one of second zones and which is corresponding to the starting point and the ending point.
Abstract: A printer that forms three-dimensional objects has two printheads, one of which is positioned to eject material drops in a direction that is parallel to a plane of a planar member on which an object is formed by the two printheads.

Abstract: A socket for a prosthetic limb is created by making a cast of a residual limb. Marks can be applied to the interior surface of the cast to indicate the locations of anatomical features of the residual limb. The marked interior surface can be scanned and the scan data can be sent to a master fabrication center. The scan data can be modified and a master can be produced from the modified scan data. The socket can then be formed from the plastic material on the master.

The die includes a die bottom part; a die top part; a die control unit; a flexible element extending along a lower edge of the die top part; and at least one adjusting bolt to adjust at least partially, via the die control unit, a spatial distance between the flexible element and the die bottom part during extrusion.
Abstract: A method for producing molded parts (16), a water-soluble casting mold (6) being produced in a first step using a layering method, in particular using a powder bed-based layering method. In a second step, the surface of the casting mold (6) is sealed with the aid of a material (9; 10). A casting of the molded part (16) is then formed by filling the casting mold (6) with a free-flowing, hardenable material (13), in particular a hydraulically setting material. After the casting has solidified, the casting mold (6) is dissolved with the aid of an aqueous solution (18), in particular a heated aqueous solution (18). The present application furthermore relates to a material system for producing a water-soluble casting mold (6), comprising at least one water-soluble material for building a casting mold (6) in a layering method, as well as comprising at least one material (9; 10) for sealing the surface of the casting mold (6).

Abstract: A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.
