3D Scanner Shining3D FreeScan Trak Pro 2

FreeScan Trak Pro2 is a portable optical coordinate measuring system built for markerless 3D scanning of medium-to-large industrial parts, delivering metrology-grade accuracy of 0.023 mm and a scan speed of up to 3 070 000 points/s. Powered by dual-camera dynamic referencing and 50 blue laser lines, it eliminates the need to place physical markers on the workpiece — saving preparation time across aerospace, automotive, and heavy-manufacturing quality-control workflows.

Markerless Dynamic Tracking: Faster Setup, Cleaner Workflow

Traditional optical scanning demands dozens — sometimes hundreds — of adhesive reflective markers stuck to the part surface. The FreeScan Trak Pro2 replaces that entire step with the FreeTrak optical tracking bar. Mounted on a tripod, FreeTrak uses infrared LEDs and a dual-camera system to track the position of the handheld TE25 laser scanner in real time, so the coordinate system stays locked to the part geometry rather than to physical markers.

The result is twofold: you spend less time preparing the part, and you avoid marker-related alignment issues on curved, dark, or reflective surfaces. When the scan scenario requires it — for instance, multi-view stitching on very large assemblies — the system also supports a conventional marker-based mode, giving you full flexibility.

Three Laser Modes for Every Surface Condition

Not every geometry responds well to a single scan pattern. The TE25 scanner ships with three selectable light-source modes, each optimised for a different use case:

• 50 crossed laser lines — maximum coverage for rapid data acquisition on large, open surfaces.
• 7 parallel laser lines — partial HD mode that captures extremely fine surface detail on small or complex zones.
• 1 single laser line — deep-hole scanning with a hole-diameter-to-depth ratio of 1 : 4, reaching cavities that crossed-line patterns cannot enter.

Paired with two 5.0 MP industrial cameras, the 50-line mode drives data capture at up to 3 070 000 points/s, converting hours of manual measurement into minutes of continuous scanning.

Metrology-Grade Accuracy at 0.023 mm

Accuracy is not a marketing claim here — it is certified. The FreeScan Trak Pro2 is evaluated according to VDI/VDE 2634 Part 3 and ISO 10360 standards, with sphere-spacing error assessed using traceable length artefacts inside an ISO 17025 accredited laboratory (temperature 20 ± 0.5 °C, humidity 40–60 % RH).

Volumetric accuracy holds strong across large working volumes: 0.062 mm within 9.6 m³ and 0.072 mm within 17.6 m³. When combined with photogrammetry, the system reaches 0.044 mm + 0.012 mm/m, making it suitable for first-article inspection and GD&T verification on aerospace and automotive components.

Expandable Tracking Volume for Large Assemblies

The maximum field of view per scan frame is 650 × 580 mm, but the effective working volume extends far beyond that. The FreeTrak bar supports three tracking-volume tiers:

• H 1 635 mm × W 2 045 mm
• H 2 540 mm × W 3 000 mm
• H 3 090 mm × W 3 702 mm

This eliminates the need for leapfrogging — the traditional technique of repositioning the measuring device and re-referencing artefacts — across the majority of medium-to-large parts, including car body panels, aircraft skin sections, and industrial tooling.

FreeProbe: Optional Contact Probing Integration

When specific dimensional features need point-based measurement — hole centres, slot widths, datum planes — the optional FreeProbe adds contact-probe capability to the same coordinate system. With an accuracy of 0.025 mm and a measurement rate of 100 points/s, the probe integrates directly with PolyWorks and Geomagic Control X for quick inspection workflows.

The ergonomic handle, multifunctional button, and ruby measuring tip allow the operator to switch between optical scanning and contact probing without recalibrating the coordinate frame.

Real-Time Meshing and Data Quality Visualisation

The bundled software generates mesh data in real time as you scan, removing the post-scan point-cloud-to-mesh processing step. A colour-coded data-quality indicator overlays directly onto the 3D model: blue regions indicate complete data, while yellow sections flag areas where additional scanning passes are needed.

Scanning-distance feedback is equally intuitive — the colour of the projected laser lines changes from blue (too far) through green (optimal) to red (too close), so the operator maintains the correct working distance by visual reference alone.

Tech Tip: Always warm up the scanner for approximately 15 minutes before calibration. The manual recommends reaching a stable device temperature of about 35 °C to ensure accuracy and precision. If the device has not been calibrated for more than 7 days, the software will prompt you to recalibrate — do not skip this step if accuracy-critical measurements are planned.
