| CO₂ Laser | ±0.1 mm | 10–30 mm/sec | Up to 15 mm (mild steel) |
1.2 CNC Press Brakes
Multi-axis CNC press brakes integrate with smart sensors and AR/VR for ultra-precise bending. They can adapt in real time based on material springback and tool wear.
II. Digital Transformation in Sheet Metal Prototyping
2.1 Automation & Robotics
Collaborative robots (cobots), automated guided vehicles (AGVs), and robotic welding arms are reducing human intervention and increasing consistency in sheet metal processes.
2.2 IoT Integration
Sensors embedded in production lines enable real-time monitoring, predictive maintenance, and digital twins. This streamlines the design–test–iteration loop for prototypes.

III. 3D Metal Printing in Sheet Metal
While additive manufacturing was once reserved for plastics, metal 3D printing is becoming more mainstream. Techniques like selective laser melting (SLM) and binder jetting are being used to create hybrid components with complex internal structures.
| Process | Typical Materials | Layer Thickness | Surface Finish (as-built) |
|---|---|---|---|
| Binder Jetting | Stainless Steel, Inconel | 30–100 µm | Rough (Ra ~15 µm) |
| Selective Laser Melting | Aluminum, Titanium | 20–50 µm | Better (Ra ~10 µm) |
IV. Material Trends and Sustainability
Modern sheet metal fabrication is no longer just about aluminum or stainless steel. Advanced alloys, composites, and coated metals are improving performance while reducing weight.
Common Materials for Prototyping at Boona Prototypes:
| Material | Key Features | Applications |
