FreeScan Trio Metrology-Grade Handheld Laser 3D Scanner
The FreeScan Trio is designed for high-precision inspection, quality control, and reverse engineering where accuracy, speed, and repeatability matter. It combines marker-free handheld laser scanning with traditional metrology workflows, giving engineers the flexibility to scan complex parts quickly while maintaining measurement confidence.
With multiple laser scanning modes and built-in photogrammetry, the FreeScan Trio adapts to a wide range of part sizes and surface conditions—from feature-rich components scanned without markers to large industrial assemblies requiring volumetric accuracy. This makes it a practical solution for real-world inspection environments, not just controlled lab setups.
Intelligent Self-Positioning Technology
Marker-Free Scanning Mode
The FreeScan Trio uses intelligent self-positioning technology to enable marker-free laser scanning on feature-rich parts. With 98 laser lines, the system captures geometry efficiently without requiring physical markers, reducing setup time and improving workflow efficiency while maintaining stable tracking.
Three Industrial 5MP Cameras
Equipped with three industrial-grade 5-megapixel cameras, the FreeScan Trio captures dense, high-quality 3D data with fine geometric detail. This camera configuration supports accurate feature recognition and consistent data capture across a wide range of surface conditions.
High-Detail Data Capture
The FreeScan Trio is engineered to capture fine geometric details with high data density, supporting accurate inspection and reverse engineering workflows. Whether scanning with markers for metrology applications or without markers on feature-rich parts, it delivers consistent, high-quality 3D data across a wide range of surfaces.
Deep Hole Scanning Mode
The FreeScan Trio supports scanning of holes, deep pockets, and fin walls using both 26-line and single-line laser modes. Optimized camera angles and dedicated scanning modes enable reliable data capture in narrow and recessed areas that are difficult to access with standard handheld laser configurations.
Video Photogrammetry (VPG)
The FreeScan Trio features SHINING 3D’s patented Video Photogrammetry (VPG) technology, which supports large-object scanning without the need for coded markers. By integrating photogrammetry directly into the scanning workflow, VPG helps maintain consistent volumetric accuracy while simplifying setup and reducing preparation time for large-scale inspection tasks.

FAQs
Yes. The FreeScan Trio has a laser scan mode, which is less sensitive to ambient light and thus delivers a better performance in scanning reflective and dark-colored surfaces.
Yes. The FreeScan Trio has a built-in photogrammetry function, which can achieve an accuracy of up to 0.02 mm + 0.015 mm/m.
Yes. When the object has rich geometric features, FreeScan Trio's 98-line mode can use feature alignment mode without markers.
Yes. The scanner provides inspection reports and calibration certificates traceable to international standards such as VDI/VDE 2634 and ISO 10360 (subject to the actual certificates issued). All calibration and verification procedures are performed in SHINING 3D’s accredited Accuracy Lab, which operates in accordance with ISO/IEC 17025 requirements.
FreeScan Trio software can export data in various formats such as ASC, OBJ, STL, and PLY.
SHINING 3D scanners are calibrated using certified artifacts or calibration panels traceable to metrology standards. Regular calibration ensures measurement traceability, maintains accuracy, and aligns the scanner with quality management requirements.
3D scanning captures the full 3D geometry of a part in one measurement. Compared to manual tools, it enables 100% surface inspection, reduces operator errors, and detects shape deformations often missed in key-point checks. Compared to CMMs, it is faster and provides richer data, especially for complex or freeform surfaces.
3D scanning is used for reverse engineering by capturing the exact geometry of a physical object and converting it into a digital 3D model or CAD file when original design data is unavailable. For 3D inspection, scanned data is compared with the CAD model to quickly identify dimensional deviations, ensuring parts meet design and quality requirements.
