Application

Design takeaway

Incorporate advanced simulation tools early in the design process to evaluate and optimize manufacturing routes, prioritizing those that offer superior sustainability and economic performance, such as additive manufacturing for complex aerospace components.

How to apply

When designing components, especially for demanding industries like aerospace, use simulation software to compare different manufacturing methods (e.g., CNC vs. additive manufacturing) based on predicted waste, energy consumption, and cost. Select build strategies within additive manufacturing that minimize support structures and maximize part density.

Project actions

  • 01When comparing manufacturing methods, consider not just the initial production but also the long-term impact, like fuel savings.
  • 02Use simulation software to test different ways of arranging parts on a 3D printer bed to see which uses the least material and time.

Method & Evidence

AimTo compare the technical and sustainability performance of CNC machining versus Laser Powder Bed Fusion (LPBF) for aerospace brackets, using simulation-driven build strategies.
MethodComparative analysis and simulation-based assessment
ProcedureThe study involved developing and simulating two LPBF build strategies (single-part distortion-minimized and multi-part volume-optimized) using software like Siemens NX and Atlas3D. These simulations were used to assess metrics such as build time, support mass, energy consumption, distortion, and buy-to-fly ratio. These simulated results were then compared against data from a conventional CNC machining route for the same aerospace bracket. Material properties of Al 7175-T7351 and Scalmalloy® were also evaluated. Environmental and economic assessments, including cradle-to-gate CO2 emissions and energy consumption, were performed for both manufacturing routes. A use-phase analysis was conducted to estimate lifetime fuel savings and CO2 emission avoidance in an aviation context.
