Discover how the Freescan Combo+ handles challenging surfaces like BLK 3.0 black paint and reflective metallics with advanced blue laser and infrared modes.
Introduction to Freescan Combo+
Scanning precision surfaces just got more exciting with the Freescan Combo+. This versatile 3D scanner is designed for complex jobs, such as calibrating CNC devices. In this test, we use a standard 1x2x3 block—a familiar tool for machinists—to push the scanner to its limits. The experiment explores how the Combo+ performs when scanning black and reflective surfaces, both known for being notoriously difficult in the 3D scanning world.
Challenges of Black and Reflective Surfaces
One of the major challenges in 3D scanning is capturing data from surfaces that absorb or reflect light in extreme ways. Black surfaces, such as those painted with BLK 3.0—an ultra-dark paint comparable to Vantablack—absorb most light, making it hard to gather accurate data. Similarly, highly reflective surfaces scatter light, causing difficulties in triangulating data points.
Testing with BLK 3.0 and Reflective Surfaces
For this test, we used two extreme examples: BLK 3.0 for ultra-dark, non-reflective surfaces, and Mirror paint—a highly reflective, metallic finish. These provide the perfect conditions to test the Freescan Combo+’s laser modes, particularly the blue laser and infrared (IR) technologies.
Laser Mode Performance
The Combo+ features multiple laser configurations, including a 50-line mode for fast scans and a 7-line mode for high-detail work. On scanning the BLK 3.0 coated object, the blue lasers captured the geometry with impressive clarity. Even with the reflective surface, the scanner handled the challenges surprisingly well.
Infrared Mode Insights
When switching to infrared mode, results were mixed. While infrared excels in scanning darker materials, it struggled with the reflective side. The BLK 3.0 surface was well-detected, but the highly reflective surface scattered the infrared light, producing little usable data. This mode is ideal for less reflective materials, but the blue lasers remain superior for reflective and glossy objects.
Optimizing Scans for Detailed Accuracy
The Freescan Combo+ allowed us to fine-tune scans by adjusting resolution and laser intensity, providing up to 3 million data points at higher settings. The results were striking, especially when using the high-detail laser modes on smaller, complex parts. When scanning reflective surfaces, the difference in detail was noticeable. However, the scanner’s precision and ability to adapt to varying surfaces made it a strong performer overall.
Key Takeaways
- Blue laser technology in the Combo+ outshines traditional scanners when dealing with reflective and glossy surfaces.
- Infrared mode is great for darker materials but struggles with highly reflective surfaces.
- Higher resolution scans offer better point density but require more time and closer scanning distances.
Conclusion: Freescan Combo+ as a Game-Changer
The Freescan Combo+ is a powerful, professional-grade scanner that excels in capturing complex surfaces with high accuracy. Its performance on difficult surfaces like BLK 3.0 black paint and reflective metals showcases the benefits of its blue laser technology. Whether you’re in the market for a new scanner or looking to upgrade, the Combo+ is worth serious consideration.
