Produce High-Quality Casings and Ducting Faster While Eliminating Tooling Costs

Industrial gas turbines require large, complex casings and ducting at low production volumes, making additive manufacturing of patterns for investment casting very economical relative to traditional tooling-based wax injection methods.

Overcome the geometry and time constraints common with conventional machined molds, replacing it with a fast, tool-less process that opens the door to greater design freedom while improving product performance.

Solving Three Gas Turbine Casings and Ducting Challenges With Additive Manufacturing

  • A man holding a 3D printed duct

    Using advanced software, stereolithography (SLA) technology and materials, our 3D printed hollow casting patterns are strong enough to support parts during manufacturing. While durable, these patterns can still collapse under their own expansion, and their unique material and design allow for complete drainage.

  • Increase Exhaust Efficiency

    The QuickCast® process is used with tremendous design freedom to create stronger, more reliable investment casting patterns for industrial gas turbine casings and ducting. This creates the possibility for smoother and more efficient gas flow structures than what is possible with traditional investment castings, which in turn improves overall turbine efficiency.
  • Casings and Ducting for Turbomachinery: Faster Product Development

  • Faster Product Development

    Investment casting with the QuickCast process reduces lead-time and costs. It requires no hard tooling, so patterns can be produced on-demand, allowing customers to economically go from CAD file to casting in days.

  • Increase Reliability

    Reducing the number of components needed for gas turbine casings and ducting assemblies means fewer points of failure, resulting in greater uptime and reliability.
