The ExOne Co. (North Huntingdon, Pennsylvania) is showcasing its washout tooling process and Binder Jetting. Its Binder Jetting technology is an additive manufacturing process in which a liquid binding agent is selectively deposited to join powder particles. ExOne washout tooling eliminates the expense and long lead time associated with manufacturing multi-piece metal breakdown tooling. It also eliminates the need for multi-piece molds that are used to make castable washout tooling media. ExOne will have several washout tooling parts on display as well as metal parts. 

Jesse Blacker, ExOne production development manager, is giving a presentation about Binder Jet additive manufacturing for water washout tooling. His presentation examines aspects of Binder Jet washout tooling including results of material characterizations studies. Blacker also is discussing printed tooling materials properties including density, compressive strength, coefficient of thermal expansion (CTE), and water solubility characteristics that demonstrate the utility of these materials for tooling trapped shape composites.

  • Aircraft composites repair moves toward maturity

    New technologies seek to address the challenges MROs will increasingly face in the age of commercial airliners with composite airframes.

  • The first composite fuselage section for the first composite commercial jet

    Spirit AeroSystems was an established aerospace supplier when it earned that distinction, winning the contract for the Boeing 787’s Section 41. Now its sights are set on the next generation of aircraft.

  • Composites 101: Tooling

    Composite parts are formed in molds, also known as tools. Tools can be made from virtually any material. The material type, shape and complexity depend upon the part and length of production run. Here's a short summary of the issues involved in electing and making tools.
