Application

Design takeaway

Consider incorporating fractal-based void structures during the design phase of additively manufactured components to embed digital information for enhanced security and traceability.

How to apply

When designing components for critical applications where supply chain integrity is paramount, explore the use of internal geometric features, inspired by fractal patterns, to embed unique identifiers.

Project actions

01When designing, think about how to create internal voids that can represent binary data (0s and 1s).
02Consider using fractal patterns as they are complex and can pack a lot of information into a small space.

Method & Evidence

AimTo investigate the feasibility of embedding digital information into additively manufactured metal components using fractal patterns and to assess the impact on material properties and tensile strength.

MethodExperimental and observational study

ProcedureDigital codes were designed using Cantor dust fractal patterns and embedded as ellipsoidal or prolate spheroid voids within ASTM E8/E8M dumbbell specimens using Direct Metal Laser Melting (DMLS). Specimens were then subjected to tensile testing, and X-ray imaging (conventional and interferometry) was used to detect the embedded information.

Strengths & Limitations

Strengths

+Directly addresses a critical issue in supply chain security.
+Combines manufacturing, data embedding, and material testing.

Limitations

It might be difficult to accurately detect very small embedded codes, and the printing process itself could introduce errors.

Reliability & validity

The study's reliability is supported by the use of standardized testing procedures (tensile testing) and controlled manufacturing parameters. Validity is enhanced by employing multiple detection methods (X-ray imaging) and comparing results against established material specifications.

Think critically

How might the complexity of the fractal pattern affect the ease of detection and the potential for data corruption during manufacturing or use?
