Is there any difference between 3D printing and additive manufacturing?
Or are they the same terms?
Well, this is the most common question people have nowadays and due to slightly the same functionality, they are misunderstood. So, to help you understand what they exactly do and the difference between these, read on the blog.
We'll discuss the major difference between these and then the decision guide for when to choose 3D Printer and when Additive Manufacturing.
Overview of 3D Printing and Additive Manufacturing
What is 3D Printing?
3D printing, a form of additive manufacturing, builds objects layer by layer, much like a traditional printer but in three dimensions. This technology is especially valuable for creating lightweight parts, offering design flexibility and material efficiency.

While 3D printing is commonly employed in smaller-scale operations, it is not typically associated with larger-scale manufacturing workflows that utilize 3D printing.
Example:
Think of a regular printer making a drawing of a house on paper. Now, imagine a 3D printer creating a small model of that same house by adding tiny bits of material layer by layer until the entire model is complete.
What is Additive Manufacturing?
Additive Manufacturing is a fancy term for creating objects by adding material layer by layer, instead of cutting and shaping it from a larger piece. It's like building with virtual Lego blocks, adding one piece at a time until you have the final product.
Example:
Imagine baking a cake. Instead of carving a cake shape from a big block of batter, you add small layers one on top of the other to create the whole cake. That's a bit like how additive manufacturing works.
Understanding the Difference Between These Two:
Aspect | 3D Printing | Additive Manufacturing |
| Definition | The process of creating a 3D object by adding layers of material based on a digital model, often a CAD drawing. | A broader concept that encompasses various processes beyond just layer-by-layer addition of material. |
| Scope | Primarily associated with consumer and recreational applications. | More commonly linked to industrial and commercial applications. |
| Material Addition | Involves adding layers of material to construct the object. | Involves adding material, which may not necessarily be in layers. |
| Example | Fused Deposition Modeling (FDM) is a common 3D printing technology. | Selective Laser Melting (SLM) is an example of an additive manufacturing process that doesn't build up layers. |
| Applications | Often used for smaller-scale operations. | Widely employed in industrial sectors such as automotive, aerospace, health, textile, architecture, and electronics. |
| Perceived Purpose | Mainly used for creating tangible objects through layer-by-layer addition. | Associated with optimizing production costs, localized production, reducing part obsolescence, and simplifying the supply chain. |
| Advantages | Precision in layer-by-layer construction. | Growth of localized production. |
| Commonly used for prototyping and hobbyist projects. | Savings on transportation and inventory costs. | |
| Limited design freedom compared to additive manufacturing. | Simplification of the supply chain. | |
| Greater design freedom and unlimited geometries. | ||
| Future Trends | Continuing to be a popular choice for consumer and hobbyist applications. | Expected to play a significant role in various sectors, including industrial, automotive, aerospace, health, textile, architecture, and electronics. |
In summary, 3D printing is a specific type of additive manufacturing primarily associated with consumer applications, while additive manufacturing is a broader term with diverse industrial applications beyond layer-by-layer material addition.
Choosing Between 3D Printing and Additive Manufacturing:
When deciding between 3D printing and additive manufacturing, it's crucial to consider the specific needs of your project and the scale of production. Each technology has its strengths and applications. Here's a guide to help you determine when to choose 3D printing and when to opt for additive manufacturing:
When to Choose 3D Printing:
Prototyping and Rapid Iteration: 3D printing is an excellent choice for rapid prototyping, allowing for quick and cost-effective iteration of designs.
Consumer and Small-Scale Applications: Opt for 3D printing when your focus is on consumer-oriented or smaller-scale applications, such as custom products, hobbyist projects, or personalized items.
Layered Construction Precision: If your project requires precise layer-by-layer construction, 3D printing technologies like FDM, SLA, or PolyJet provide the needed precision.
Cost-Effective for Low Volumes: When dealing with low production volumes, 3D printing can be a more cost-effective solution, especially considering the absence of tooling and molds.
Ease of Use and Accessibility: 3D printers are generally more accessible and user-friendly, making them suitable for individuals, small businesses, and educational purposes.
When to Choose Additive Manufacturing:
Industrial Production: Consider additive manufacturing for larger-scale industrial production where efficiency, speed, and material versatility are paramount.
Complex Geometries and Design Freedom: Opt for additive manufacturing when your project demands intricate and complex geometries, as it offers greater design freedom compared to traditional manufacturing methods.
Economic Optimization: If your primary goal is to optimize production costs, additive manufacturing can be advantageous, thanks to benefits like part obsolescence reduction, simplified supply chains, and reduced stock.
Localized Production: Choose additive manufacturing for the ability to produce components or products closer to the point of use, reducing transportation costs and environmental impact.
Materials Diversity: When your project requires a wide range of materials, including specialized alloys or high-performance polymers, additive manufacturing provides the flexibility to work with diverse materials.
In conclusion, the choice between 3D printing and additive manufacturing depends on the specific requirements of your project, the scale of production, and the desired outcomes. Assessing factors like precision, scale, material needs, and economic considerations will guide you towards the most suitable technology for your application.
