  • Patent number: 10906249
    Abstract: An additive manufacturing system, and corresponding method, prints a sacrificial component using a 3D printing system that includes a spreading mechanism for spreading unbound powder to form layers of a powder bed and a printing mechanism for jetting binder fluid into the unbound powder to form the sacrificial component. The system forms the sacrificial component with a feature that provides a resistive force to a shear force imposed by the spreading mechanism during the spreading. The system prints a part with the 3D printing system in a coupled arrangement with the sacrificial component. The coupled arrangement in combination with the resistive force is sufficient to immobilize each printed layer of the part to resist the shear force imposed by the spreading mechanism during spreading of the unbound powder above each printed layer of the part. After printing, and before or after post-processing, the part and sacrificial component are separated.

  • Patent number: 8815044
    Abstract: A beam of fiber-reinforced curable thermosetting composite material is preliminarily assembled in an uncured condition. The beam is placed between two forming tools, namely a lower and an upper tool, shaped in such a way as to give the lower and upper flanges a predetermined shape, at least one of the flanges having a non-rectilinear profile viewed in a longitudinal vertical plane. Two longitudinally elongate rigid inserts are placed between the flanges at the sides of the web and are covered in respective airtight tubular bags. The spaces between the upper tool and the lower tool on the two opposite longitudinal sides are sealed. The open opposite ends of the tubular bags are also sealed in such a manner that the pressure applied in an autoclave during the step of curing causes the tubular bags to swell and presses them against the two opposite faces of the web and against the flanges of the beam. On completion of curing, the upper forming tool is removed and the inserts are extracted sideways.

  • Patent number: 8815145
    Abstract: A method and apparatus for fabricating a composite part with a shape memory polymer (SMP) apparatus usable as both a rigid tool and as a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. The composite material may be applied onto the SMP apparatus and then placed into a rigid external mold and heated to composite cure temperatures at which the SMP apparatus is malleable. In some embodiments, an impermeable sheet of material may also be placed over portions of the composite material to compress it against the SMP apparatus. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external mold. When the composite material is cured, the pressure differential may be equalized and/or reversed and the malleable SMP apparatus may be removed from within the composite part.

  • Patent number: 8771583
    Abstract: Polyester compositions described herein have properties which are particularly suitable for extrusion blow molding (EBM). These properties relate primarily to the rate of crystallization and melt strength or melt viscosity. Articles prepared from the polyester compositions exhibit good clarity, aesthetics, and other physical properties. The polyester compositions also exhibit broad molecular weight distribution (MWD), resulting in improved processability and melt strength. The crystallization rate allows for good drying characteristics while also enabling the use of regrind. In addition, the compositions exhibit improved recyclability, such as in existing PET recycling streams. In one aspect, articles are prepared in an extrusion blow molding method by combining a dry first polyester copolymer component, a dry second polyester component, and a chain extender to form a feed material suitable for extrusion blow molding.
