Key Features of CNC Rapid Prototyping

• Precision & Accuracy: CNC machines provide exceptionally high levels of precision, making them ideal for intricate designs.
• Material Variety: Suitable for a broader selection of materials—including metals and high-performance plastics—CNC can produce durable parts.
• Scalability: CNC is often more viable for producing multiple units without a significant loss in quality or performance.

The Rise of 3D Printing

3D printing, also known as additive manufacturing, is a process where layers of material are gradually added to create a 3-dimensional object. This technology has made a name for itself due to its flexibility and ease of use in creating complex geometries.

Key Features of 3D Printing

• Design Freedom: Allows for complex designs and customizations that are often impossible with traditional manufacturing methods.
• Speed of Prototyping: Can produce prototypes much faster, especially for low-volume applications.
• Cost-Effective for Low Volumes: Ideal for producing unique designs or small batches without the high setup costs.
