This presentation will describe how Lockheed Martin uses additive manufacturing (AM) to rapidly develop tooling for autoclave and oven cure applications, such as composite and metal bond tools. AM allows Lockheed Martin to evaluate new ideas faster than traditional manufacturing methods with part turnaround times measured in hours instead of weeks or months. This presentation will include several cases where AM grown components saved time and cost in delivering solutions for elevated temperature applications. Various high-temperature materials retain service temperatures that support composite cure cycles. Lockheed Martin is evaluating high-temperature, large-format AM materials and coatings to determine best practices, design criteria, material performance, and cost savings. The fast turnaround time of AM allows Lockheed Martin to evaluate multiple designs and incorporate use-case feedback rapidly.
- Evaluate benefits of BAAM tooling in elevated temperature applications
- Identify processes and materials for various elevated temperature applications
- Understand direct print autoclave-ready composite tooling
Why Is It Important?
Tooling costs for aerospace manufacturing are often very high with lengthy lead times. Legacy platforms no longer have original tooling, which can make repairs/maintenance challenging, time consuming and costly. Big Area Additive Manufacturing allows for the production of rapid, low cost tooling for elevated temperature applications, supporting oven and autoclave cycles.
