    摘要: A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.

    摘要: A novel polymeric binder for an antifouling paint includes greater than 2.5 to less than 25 mole percent of a unit from a tributyltin acrylate or methacrylate monomer group, an acrylic or methacrylic ester monomer unit having selected substituent groups in the ester moiety so that the ester is hydrolyzable at a suitable rate in seawater, and a copolymerizable ethylenically unsaturated monomer unit.The presence of the hydrolyzable ester group in the polymer binder of the present invention enables the paint to erode at a desired rate in seawater even with the low tin content in the polymer, thereby providing a desired low level of tin in solution and exposing a fresh paint surface periodically.

    摘要: A method and apparatus for forming a relatively thin releasable layer of copper on a carrier substrate. First, a separation facilitating layer is provided on the carrier substrate. A layer of vapor-deposited copper is then formed over the separation facilitating layer to protect the separation facilitating layer during subsequent processing. Thereafter, the thickness of the copper layer is increased by the electrodeposition of copper onto the vapor-deposited layer. The copper layer is applied to a dielectric and is released from the carrier substrate at the separation facilitating layer.
