Additive Manufacturing Design Strategies: Manufacturing vs. Function Driven Approaches
Category: Innovation & Design · Effect: Strong effect · Year: 2015
Leveraging additive manufacturing (AM) in product development requires a strategic choice between a manufacturing-driven approach, enabling process substitution, and a function-driven approach, enhancing product performance.
Design Takeaway
When designing for additive manufacturing, consciously select either a manufacturing-driven or function-driven strategy to guide your design decisions and maximize the technology's potential.
Why It Matters
Understanding these distinct design strategies is crucial for designers and engineers to effectively harness the unique capabilities of AM. This allows for the creation of products with significant added value for both manufacturers and end-users, optimizing the product's entire lifecycle.
Key Finding
The research identifies two primary strategies for using additive manufacturing: one that focuses on optimizing the manufacturing process itself, and another that prioritizes enhancing the product's functional performance.
Key Findings
- A manufacturing-driven design strategy allows for the substitution of manufacturing processes later in the product lifecycle.
- A function-driven design strategy focuses on increasing the performance of a product by utilizing AM's unique capabilities.
- The choice of design strategy significantly impacts the development process and component design.
Research Evidence

Method: Case Study Analysis
Procedure: The paper presents and illustrates two distinct design strategies for additive manufacturing: a manufacturing-driven strategy and a function-driven strategy, supported by two illustrative case studies.
Context: Product development and manufacturing engineering
Design Principle
Strategic intent in design for additive manufacturing dictates the approach to process integration and performance enhancement.
How to Apply
Before commencing a design project involving additive manufacturing, clearly define whether the primary goal is to optimize production processes or to achieve superior product functionality, and tailor the design approach accordingly.
Limitations
The presented strategies and cases may not cover all possible applications or nuances of additive manufacturing across diverse industries.
Student Guide (IB Design Technology)
Simple Explanation: When you design things using 3D printing (additive manufacturing), you can either focus on making the manufacturing process easier or on making the product work much better. Both ways are good, but you need to choose one to start with.
Why This Matters: Understanding these strategies helps you make informed design decisions when using advanced manufacturing techniques like 3D printing, leading to more innovative and successful products.
Critical Thinking: How might a hybrid approach, combining elements of both manufacturing-driven and function-driven strategies, yield even greater benefits in specific product development contexts?
IA-Ready Paragraph: The integration of additive manufacturing into product development necessitates a strategic approach, as highlighted by Klahn et al. (2015), who identify two core strategies: a manufacturing-driven approach that facilitates process substitution throughout the product lifecycle, and a function-driven approach aimed at enhancing product performance. The selection between these strategies profoundly influences the design process and the final component design, offering designers a framework to leverage AM's unique capabilities for added value.
Project Tips
- Clearly articulate which design strategy (manufacturing-driven or function-driven) you are employing in your design project.
- Use case studies to demonstrate how your chosen strategy leads to specific design outcomes.
- Consider the implications of your strategy on the product's lifecycle and user experience.
How to Use in IA
- Reference this paper when discussing the strategic considerations for designing with additive manufacturing.
- Use the two strategies as a framework for analyzing your own design choices or those of existing products.
Examiner Tips
- Demonstrate a clear understanding of the strategic choices available when designing for additive manufacturing.
- Justify your design decisions by linking them to either a manufacturing-driven or function-driven approach.
Independent Variable: Design strategy (Manufacturing-driven vs. Function-driven)
Dependent Variable: Impact on product development process, component design, manufacturer value, user value
Controlled Variables: Additive manufacturing process type, product complexity, material properties
Strengths
- Provides a clear dichotomy of strategic approaches for AM.
- Uses case studies for practical illustration.
Critical Questions
- What are the quantitative metrics to assess the 'added value' for manufacturers and users?
- How do these strategies adapt to different types of additive manufacturing technologies (e.g., FDM, SLA, SLS)?
Extended Essay Application
- Investigate the application of these strategies in a specific industry (e.g., aerospace, medical devices) and analyze their effectiveness.
- Develop a new product concept that explicitly utilizes one of these strategies and justify the design choices based on the chosen strategy.
