3D printing is an additive manufacturing process that creates parts layer by layer using digital design files and specialized printing equipment.

The technology is commonly used for prototyping, tooling, low volume production, product development, and custom component manufacturing across industries including aerospace, automotive, medical, and industrial equipment.

3D printing can use materials such as plastics, resins, composites, and metals depending on the application and performance requirements.

Learn how manufacturers adapt production strategies to improve supply chain flexibility and operational efficiency.

3D printing systems build components by depositing or solidifying material layer by layer according to a digital CAD model.

Different printing methods use different technologies, including fused deposition modeling, powder bed fusion, stereolithography, and metal additive manufacturing.

Material selection, layer resolution, print orientation, and post-processing requirements all influence final part quality and performance.

• 3D printing supports faster prototyping and design iteration
• Additive manufacturing can reduce tooling requirements
• Custom geometries are often easier to produce
• Low volume production may become more cost-effective
• Rapid development cycles improve engineering flexibility
• Distributed manufacturing can improve supply chain responsiveness

3D printing builds parts additively layer by layer, while traditional manufacturing often removes material through machining or shapes material through forming and casting processes.

Traditional methods are typically more efficient for high volume production, while 3D printing is often preferred for prototyping and complex low volume parts.

3D printing becomes important when manufacturers need rapid prototyping, custom geometries, shorter development cycles, or lower volume production flexibility.

This matters when engineering teams are testing designs, producing tooling, or reducing lead times for specialized components.

If you’re comparing production methods, additive manufacturing may help accelerate development while reducing tooling investment for certain applications.
