In today’s rapidly evolving manufacturing landscape, the terms additive manufacturing and 3D printing are often used interchangeably. But are they really the same thing? And more importantly, how do they impact modern production strategies for OEMs and industrial manufacturers?
At Amfas International, we specialize in advanced fabrication techniques, including additive manufacturing, to support product innovation and time-to-market efficiency. This guide helps clarify the overlap and distinctions between additive manufacturing and 3D printing.
What is Additive Manufacturing?
Additive manufacturing is a process of creating parts by building them layer-by-layer using digital 3D models. It contrasts traditional subtractive methods, which remove material from a solid block. It includes several processes such as:
- Stereolithography (SLA)
- Fused Deposition Modeling (FDM)
- Selective Laser Sintering (SLS)
- Direct Metal Laser Sintering (DMLS)
It is commonly used for prototyping, tooling, and even final production in aerospace, automotive, medical, and industrial sectors.
What is 3D Printing?
3D printing refers to the same set of technologies used in additive manufacturing, but it is generally used in a more consumer-focused or prototyping context. It’s often associated with smaller desktop printers, whereas additive manufacturing refers to industrial-scale, production-grade technologies.
In short: all 3D printing is additive manufacturing, but not all additive manufacturing is just 3D printing.
Key Differences Between Additive Manufacturing and 3D Printing
| Feature | Additive Manufacturing | 3D Printing |
|---|---|---|
| Usage Context | Industrial, large-scale | Consumer, hobbyist, prototyping |
| Materials | Metals, polymers, ceramics | Mostly thermoplastics, resin |
| Scale | Production and end-use parts | Functional prototypes, small runs |
| Technology Variety | Includes 7 ASTM-defined categories | Often limited to FDM, SLA |
| Quality Control | ISO-grade, certified environments | Less rigorous standards |
Are They the Same?
Is 3D printing and additive manufacturing the same?
They refer to the same core process but differ in usage. 3D printing is often informal or entry-level, while additive manufacturing is the professional, industrial-grade application.
Is additive manufacturing another name for 3D printing?
Yes, it’s the technical term. Additive manufacturing includes all 3D printing techniques used in industrial applications.
What is the role of CAD in 3D printing?
CAD (Computer-Aided Design) software is used to create 3D models, which are then converted into instructions (G-code) for 3D printers.
Additive Manufacturing vs 3D Printing: Pros and Cons
| Factor | Additive Manufacturing | 3D Printing |
| Speed | Fast for short runs, but slower than injection molding for mass production | Great for fast prototyping |
| Customization | High | High |
| Material Variety | Broad (including metals) | Limited (mostly plastics) |
| Cost Efficiency | Efficient for low-to-medium volume | Costly for larger runs |
| Post-Processing | Required for final parts | Often minimal |
Industry Applications and Examples
- Aerospace: Lightweight brackets and engine components (DMLS, SLS)
- Automotive: Custom tooling and jigs (FDM, SLA)
- Medical: Patient-specific implants (DMLS, SLA)
- Consumer Goods: Prototyping and design iteration
Amfas supports clients with tailored additive manufacturing solutions designed for industrial durability, accuracy, and repeatability.
Cost Comparison
Additive manufacturing vs 3D printing cost is highly dependent on the scale:
- 3D printing is inexpensive for single prototypes
- Additive manufacturing scales better and becomes more cost-effective for low-to-mid volume production with tight tolerances
We work with clients to evaluate the most cost-effective option for their part geometry and volume.
Types of Additive Manufacturing and 3D Printing
According to ASTM, there are 7 categories:
- Material extrusion (FDM)
- Vat photopolymerization (SLA, DLP)
- Powder bed fusion (SLS, DMLS)
- Material jetting
- Binder jetting
- Sheet lamination
- Directed energy deposition
Amfas leverages multiple technologies depending on part complexity, material needs, and production timeline.
Conclusion
Additive manufacturing and 3D printing share the same foundation, but differ in scope and scale. At Amfas, our expertise in additive manufacturing ensures clients receive parts that are not only functional but also manufacturable at scale.
