Journal of Materials Engineering and Performance · 2022

Key Findings

01Powder Bed Fusion, Directed Energy Deposition, and solid-state processes are common metal AM methods, each with unique energy sources and feedstock requirements.
02Component requirements significantly influence the choice of AM process, necessitating consideration of geometric variations, material properties, and performance evaluations.
03A multi-attribute analysis framework, encompassing geometry, metallurgy, cost, post-processing, and supply chain maturity, is crucial for robust process selection.

Application

Design takeaway

Implement a structured, multi-attribute evaluation framework when selecting additive manufacturing processes for critical components like those in aerospace.

How to apply

When designing a new aerospace component using additive manufacturing, create a checklist or scoring system that evaluates potential AM processes based on geometric complexity, required material properties, cost targets, necessary post-processing steps, and the maturity of the supply chain for that process.

Project actions

01When selecting a manufacturing process for your design, clearly define the criteria you will use for comparison.
02Gather data from multiple sources to support your process selection rationale.

Method & Evidence

AimWhat are the key attributes and trade-offs to consider when selecting a metal additive manufacturing process for aerospace components?

MethodLiterature review and data compilation

ProcedureA review of existing literature, internal studies, and industry partner data was conducted to compile information on various metal additive manufacturing processes. This data focused on attributes such as geometric capabilities, metallurgical properties, cost, post-processing requirements, and supply chain maturity.

ContextAerospace component manufacturing

Variables

IVAdditive Manufacturing Process Type (e.g., PBF, DED)

DVSuitability for Aerospace Component (measured by performance, cost, feasibility)

CVComponent Requirements (e.g., specific geometry, material properties, operating environment)

Strengths & Limitations

Strengths

+Provides a structured framework for a complex decision.
+Integrates multiple critical factors beyond just technical capability.

Limitations

The availability of detailed cost and supply chain maturity data for all processes might be limited.

Reliability & validity

The reliability of the findings depends on the quality and comprehensiveness of the compiled data. Validity is enhanced by drawing from multiple sources (literature, internal studies, industry data).

Think critically

How might the relative importance of these attributes (geometry, metallurgy, cost, etc.) shift depending on the specific type of aerospace component being designed (e.g., a structural part versus a thermal management component)?

Design Principles

"In complex manufacturing scenarios, a systematic, data-driven, multi-attribute decision-making process leads to optimized outcomes."

This structured approach to process selection mitigates risks associated with choosing an unsuitable manufacturing method, leading to more reliable, cost-effective, and performant aerospace components. It enables designers and engineers to make informed decisions early in the design cycle.

What This Means for Your Design

Choosing the right 3D printing method for metal airplane parts is tricky. This research shows you need to look at how complex the part is, what materials it needs, how much it costs, what happens after printing, and if the suppliers are ready.

How to use in your project

1.Use the multi-attribute analysis approach as a framework for justifying your chosen manufacturing method in your design project.
