As the use of 3D printing becomes more widespread across industries, the need to evaluate and standardize AM adoption grows. Traditional maturity models, however, often fall short in capturing the nuances of AM adoption, leaving companies without a clear understanding of their progress.

The Gaps in Traditional Maturity Models
Traditional maturity models, such as the Capability Maturity Model (CMM) and the Technology Readiness Level (TRL) scale, have been widely used to assess the maturity of various technologies. However, these models have limitations when applied to AM. For instance, they often focus solely on technological aspects, neglecting organizational and cultural factors that play a crucial role in successful AM adoption.
The Need for a Fuzzy Logic Model
To address the gaps in traditional maturity models, researchers at NOVA University of Lisbon have developed a fuzzy logic model specifically designed to evaluate AM maturity. This model captures the nuances of AM adoption, taking into account the complex interactions between organizational, cultural, and technological factors.
Understanding the Fuzzy Logic Model
The fuzzy logic model evaluates AM maturity across three key areas: organizational, cultural, and technological. Each area is further divided into several sub-criteria, as shown in the following table:
| Area | Sub-criteria |
|---|---|
| Organizational | Strategy, Leadership, Communication, Resources |
| Cultural | Workforce Readiness, Training, Innovation |
| Technological | Technology Implementation, Material Properties, Quality Assurance |
Organizational Maturity
The organizational area assesses the company’s overall strategy, leadership commitment, and resource allocation for AM adoption. This includes evaluating the presence of a clear AM strategy, leadership support, and dedicated resources for AM initiatives.
Cultural Maturity
The cultural area evaluates the workforce readiness and training, innovation capabilities, and overall cultural mindset towards AM adoption. This includes assessing the presence of trained personnel, innovation processes, and a culture that encourages experimentation and learning.
Technological Maturity
The technological area assesses the implementation of AM technology, material properties, and quality assurance processes. This includes evaluating the presence of AM equipment, material selection, and quality control processes.

Case Study: An Automotive Supplier’s AM Maturity
A case study at an automotive supplier provides insights into the effectiveness of the fuzzy logic model. The company had a strong performance in organizational and technological maturity, with a clear AM strategy and dedicated resources. However, the study revealed a gap in workforce training and leadership skills, highlighting the need for improvement in cultural maturity.

The Importance of AM Maturity Models
AM maturity models, such as the fuzzy logic model, play a crucial role in standardizing processes, refining material properties, and contributing to the future of 3D printing. By assessing AM maturity, companies can identify areas for improvement, optimize their AM adoption, and stay competitive in the industry.
Alternative Approaches to Assessing AM Maturity
While the fuzzy logic model offers a comprehensive approach to assessing AM maturity, other companies are taking alternative approaches. Some focus on quality assurance, using dimensional, surface, and material property assessment solutions to evaluate AM parts.
| Company | Alternative Approach |
|---|---|
| Company A | Quality Assurance: Dimensional and Surface Assessment |
| Company B | Material Property Assessment Solutions |
| Company C | Hybrid Approach: Combining Different Assessment Methods |
Future Research and Applications
Future research aims to expand the application of the fuzzy logic model across multiple industries, refining its framework to support organizations as they navigate their AM journey. The model’s flexibility and adaptability make it an attractive solution for companies from various sectors, including aerospace, healthcare, and consumer goods.
As you continue on your AM journey, consider using a fuzzy logic model or alternative approaches to assess your AM maturity. By understanding your strengths and weaknesses, you can optimize your AM adoption and stay ahead of the competition in the rapidly evolving world of 3D printing.
