In today’s manufacturing landscape, the terms “3D printing” and “additive manufacturing” are often used interchangeably. But are they truly the same? While they share similarities, there are key distinctions between the two. This blog will help you understand the relationship between 3D printing and additive manufacturing and when to use each term.
What is 3D Printing?
3D printing refers to the process of creating a three-dimensional object from a digital model, such as a CAD (Computer-Aided Design) drawing.
This technology has revolutionized how objects are designed and produced. The process involves slicing the digital model into thin layers, which the 3D printer then builds up layer by layer using various materials.
A variety of materials are used to create these models, including metal powders, thermoplastics, and resins. Common 3D print technologies include:
- FDM (fused deposition modeling): A print technology that extrudes a thermoplastic filament to create the layer-by-layer model.
- SLA (stereolithography): A print technology where a photosensitive liquid resin is solidified under an ultraviolet laser.
- PolyJet or Material Jetting: A print technology that uses liquid photopolymers and builds parts by depositing the ultra-fine droplets of these liquid photopolymers on a build platform through the print head(s).
3D printing is commonly associated with small-scale, one-off productions and is often used by hobbyists.
What is Additive Manufacturing?
It refers to an entire industrial manufacturing process that includes not only the creation of objects but also several other essential steps.
Additive manufacturing (AM) encompasses 3D printing but goes beyond just the printing process. While 3D printers play a crucial role, additive manufacturing involves a broader, more complex workflow.
The additive manufacturing process can include:
- Modeling: Developing a digital design using CAD software.
- Material Traceability: Ensuring the materials used are tracked and meet quality standards.
- Workflow Management: Coordinating the various stages of production.
- Post-Processing: Finishing techniques such as painting, polishing, or heat treatments to enhance the final product.
- Quality and Inspection Systems: Rigorous checks to ensure that the final product meets all necessary specifications.
So What’s the Difference?
The key difference lies in the scope and application. 3D printing usually refers to smaller-scale operations, often at the consumer or hobbyist level. While additive manufacturing refers to a comprehensive production process used in industrial settings.
Key Takeaways:
- 3D Printing: Ideal for small-scale, prototype, or hobbyist applications.
- Additive Manufacturing: Involves a full production workflow and is used in industrial and large-scale manufacturing contexts.
So while they both refer to similar processes, they are subtly different. When choosing which term to use, consider the context. If you’re referring to a process with multiple steps in an industrial setting, “additive manufacturing” is the appropriate term. For smaller-scale or one-off productions, “3D printing” is more accurate.
By understanding these differences, you can better navigate the evolving landscape of modern manufacturing and use the right terminology for your needs.
