Part Identification for Additive Manufacturing: A Data-Driven Approach

As additive manufacturing (AM) continues to mature into a viable production technology, manufacturing organizations face a critical challenge: how to systematically and effectively identify which parts are suitable candidates for AM production.

While AM offers unprecedented design freedom and potential cost savings, the identification of suitable parts remains one of the major barriers to widespread industrial adoption (Zhang et al., 2021).

The impact of getting this decision right cannot be overstated. Recent implementations demonstrate the transformative potential of proper part selection:

A major automotive manufacturer achieved $2.3M in annual production cost savings and reduced failed AM attempts by 25% through systematic part identification
An aerospace manufacturer cut their part qualification time in half while achieving 60% improvement in first-time-right production
Organizations implementing data-driven selection methods have seen up to 45% reduction in part evaluation time and 30% fewer failed AM attempts

However, recent research indicates that poor part selection is still responsible for a significant portion of failed AM implementations, with traditional experience-based selection methods falling short in objectivity and transferability (Knofius et al., 2020). This challenge has led to the emergence of data-driven approaches that promise more systematic and reliable part identification processes.

The Challenge of Part Selection

Manufacturing engineers must consider multiple factors when evaluating parts for AM:

Geometric complexity and design optimization potential
Production volume requirements
Material specifications and properties
Economic viability and cost considerations
Quality and performance requirements

As noted by (Son et al., 2023), the complexity of these interrelated factors makes manual evaluation processes increasingly inadequate for modern manufacturing environments. The need for a more systematic, data-driven approach has never been more critical for organizations seeking to capitalize on the advantages of additive manufacturing while minimizing risk and maximizing return on investment.

Historical Context

The Evolution of Smart Part Selection

The story of how manufacturers choose parts for additive manufacturing reflects the industry's rapid transformation from art to science. Let's explore how this evolution has revolutionized manufacturing decision-making:

The Expert Era: Pre-2010

In the early days, choosing parts for AM was more art than science. Companies relied heavily on:

Individual expertise and gut feelings
Trial and error approaches
Knowledge siloed within expert teams
Manual, time-consuming processes

This approach created significant business challenges:

Inconsistent results across teams and facilities
High costs from failed attempts
Difficulty scaling operations
Loss of expertise when key personnel left

The Systems Revolution: 2010-2015

Forward-thinking manufacturers began implementing structured approaches that delivered:

Faster decision-making through basic digital tools
More consistent results with standardized frameworks
Better cost control through analytical models
Reduced risk with systematic screening

The Digital Transformation: 2015-Present

Today's smart manufacturing environment leverages powerful technologies that drive bottom-line results:

AI-Powered Decision Support

Instant part analysis through machine learning
Consistent, bias-free evaluation criteria
Streamlined digital workflows that save time and money
Real-time feedback for design optimization

Advanced Analysis Tools

Automatic detection of manufacturing challenges
Built-in cost optimization
Predictive quality assessment
Integration with existing production systems

This evolution has transformed part selection from a bottleneck into a competitive advantage. Modern manufacturers can now make faster, smarter decisions about which parts to produce through AM, leading to significant cost savings and improved production efficiency.

b) Manufacturability Analysis

Assessing Part Manufacturability

When evaluating parts for additive manufacturing, several critical aspects must be analyzed systematically. Based on research by Knofius et al. (2020), a comprehensive manufacturability assessment should include four key components:
