What are the differences between 3D printing and CNC machining?

What are the differences between 3D printing and CNC machining?

3D printing is an additive manufacturing process that builds objects layer by layer, while CNC machining is a subtractive process that removes material from a solid block to create parts.

Which method is more cost-effective for small production runs?

For small production runs, 3D printing is often more cost-effective due to lower setup costs and faster turnaround times.

What materials can be used in both processes?

Both processes can use a variety of materials, including plastics, metals, and composites, but the specific materials available may vary.

Are there any limitations to 3D printing compared to CNC machining?

Yes, 3D printing can have limitations in terms of strength, surface finish, and precision compared to CNC machining, which typically offers higher accuracy.

Which method is better for prototyping?

3D printing is generally better for prototyping due to its speed and flexibility in design changes.
