A dental restoration apparatus that eliminates time-consuming, labor-intensive steps conventionally needed to fabricate molds, and thereby facilitates dental restorations in a shorter time, while reducing the discomfort and embarrassment sometimes associated with provisional restorations, which includes an additive manufacturing apparatus (e.g., a 3-D printer) having a tool head (e.g., a print head) and a fixture for controlling the position of the tool head relative to the teeth of a patient, allowing fabrication of a planned dental structure directly on an existing dental structure.

Described are methods and systems for identifying processing locations in composite layups. An optical magnetic marker is magnetically supported by a layup tool at a target position, such that a portion of the marker protrudes above the tool processing surface. When a composite layup is placed onto that surface, the protruding portion extends into the layup at a processing location. When the layup is cured, the marker is permanently embedded into the layup. Separating the cured layup from the tool removes the marker from the tool and allows an additional marker to advance into the target position for processing another layup. The embedded marker or, more specifically, marker's reflective surface is used during optical inspection of the layup surface to precisely determine the processing location. In some examples, the marker is consumed while the layup is processed at that location,

The invention provides a method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).

A molding method of a waterproof member is provided. The waterproof member is molded by molds and is for a coated electric wire. The molds include mold division surfaces including molding portions and electric wire mold clamping portions. The electric wire mold clamping portions are to sandwich the coated electric wire at sides of the molding portions. One of the electric wire mold clamping portions includes a convex portion and a side wall erected on an end of the convex portion. The other of the electric wire mold clamping portions includes a concave portion. One of the molding portions includes a side wall entering groove into which the side wall enters. The method includes molding the waterproof member accommodated in the concave portion with the waterproof member being pressed by the convex portion toward a direction in which one of the mold is attached to the other.

A railroad crosstie (tie) may be fabricated from a composite material including a fiber reinforced polymer shell manufactured by pultrusion or other process, and filled by a suitable material, typically selected from expanded elastomeric polymer (such as polyurethane resin or other polymer), concrete, lightweight concrete formed by conventional aggregate, sand, cement, water, and an ultra light filler such as natural materials, sawdust, beads of expanded polymer such as expanded polystyrene, microspheres of glass or plastic, a recycled wooden tie in conjunction with any of the above, or the like. Fasteners may be driven such as spikes, threaded, such as screws, lag screws, spreading screws, rivets, or the like into apertures, pilot holes, or directly into fill absent apertures therein.

A method for manufacturing a thrust reverser blocker door may comprise thermoforming a sandwich panel comprising a facesheet, a backsheet, and a honeycomb core. The method may further comprising overmolding a mounting structure onto the backsheet. The first thermoplastic material may comprise a continuous fiber reinforced thermoplastic composite material. The second thermoplastic material may comprise a discontinuous fiber reinforced thermoplastic composite material.
