Additive Manufacturing Produces Impellers Faster and More Efficiently Than Traditional Methods

Improve Impeller Performance with Additive Manufacturing

  • a 3D rendering of an impeller
  • Greater Impeller Efficiency

    Additive manufacturing opens new levels of design complexity that would be very challenging to produce with conventional manufacturing. As such, more sophisticated ducted impellers can be produced to achieve increased efficiency to compress air. Topology optimization and lattice structure capabilities enable weight reductions of the massive impeller section, important for rotating parts.

  • Rapid Design Iterations

    To anyone designing impellers, turbines, and similarly complex objects, the ability to quickly and inexpensively produce parts for form, fit, and function testing not only helps to optimize variables that affect gas and fluid flow performance, but also eliminates the risk that products might not perform as expected. With additive manufacturing, you have the capability to get functional prototypes in days instead of weeks, without tooling constraints.

  • Reduced Costs and Faster Lead-Times

    Traditional manufacturing of impellers from billet can represent up to 80% of material waste. This is a costly process, especially with expensive alloys such as titanium. With the Direct Metal Printing additive manufacturing process, the material is transformed into a part. When it comes to investment casting of impellers in any alloy, additive manufacturing offers a lower cost per unit for these low-volume production/high-value components. Eliminating the need for tooling to create sacrificial patterns, stereolithography QuickCast casting patterns deliver ultimate speed and flexibility.

The Expertise and Solutions for Effective Impeller Manufacturing

  • Achieve Scalable Processes

    3D Systems has the equipment, materials, and technical knowledge needed to develop scalable, cost-efficient manufacturing processes. The result is that industrial gas turbine manufacturers and suppliers can transition from prototype to production quickly, while also supporting legacy equipment with replacement and aftermarket parts in any quantity, in far less time.

  • Seamless Large Metal Parts

    Within our broad range of advanced additive manufacturing technologies, materials and software solutions, we can deliver seamless 3D printed metal parts of 500 x 500 x 450 mm within tight tolerances and with outstanding material properties.

  • Unique Materials Capabilities

    Due to the unique vacuum chamber technology of our metal printers, enabling best-in-class low oxygen atmosphere (<25 ppm), we see improved material properties, increased material efficiency, and reduced argon gas consumption. This results in exceptionally strong parts of high chemical purity, in even challenging materials such as titanium alloys.

  • The Flexibility of Tool-Less Casting Patterns

    Our advanced software, hardware, and materials for 3D printed sacrificial casting patterns enable impeller manufacturers to create large, complex casting patterns in a fraction of the time it takes to create molds using traditional tooling. By using our additive manufacturing process, you can create lightweight, hollow patterns that allow for greater design complexity, reduced component weight, and improved impeller efficiency.
