Solutionix REXCAN DS2 3D Scanner

Overview

The Solutionix REXCAN DS2 is a high-precision, non-contact optical 3D scanner engineered specifically for demanding applications in jewelry manufacturing, dental prosthetics, and fine-detail industrial metrology. It employs phase-shift optical triangulation — a robust, high-repeatability method that projects structured white-light patterns onto the object surface and reconstructs 3D geometry via synchronized dual-camera capture. Unlike laser-based systems, the DS2’s LED-powered white-light illumination eliminates speckle noise, enables consistent data acquisition on reflective, translucent, or dark surfaces (e.g., gold alloys, zirconia blanks, wax patterns), and delivers sub-100 µm volumetric accuracy across its calibrated scan volumes. Its compact benchtop architecture integrates a precision 2-axis rotary-tilt stage and rigid optical housing, ensuring mechanical stability during repeated scanning cycles under laboratory or production-floor conditions.

Key Features

• Dual high-resolution optical imaging modules: Synchronized stereo capture enables full-surface coverage without manual repositioning, significantly reducing occlusion and improving mesh completeness — especially critical for ring shanks, prong settings, and undercut crown margins.
• White-light structured illumination: LED-based pattern projection with >30,000-hour operational lifetime ensures stable intensity and spectral consistency, eliminating thermal drift and enabling reliable day-to-day calibration retention.
• Narrow 15° triangulation angle: Optimized for deep cavity access and high-aspect-ratio feature capture — such as internal mold channels, engraving grooves, and dental die preparations — without requiring destructive sectioning or filler application.
• USB 2.0 plug-and-play interface: No external power supply or frame grabber required; compatible with standard industrial PCs meeting minimum GPU and RAM specifications for real-time point cloud processing.
• Open-format data output: Native STL export (ASCII and binary) ensures seamless interoperability with major CAD/CAM platforms including exocad, 3Shape Dental System, Rhinoceros, Geomagic Design X, and CNC milling software used in jewelry wax casting and dental milling workflows.
• User-configurable automated scan paths: Intuitive GUI allows definition and storage of multi-angle rotation sequences — ideal for batch scanning of standardized components like earring backs or orthodontic attachments — with repeatable positioning repeatability < ±0.02°.

Sample Compatibility & Compliance

The REXCAN DS2 accommodates a broad range of non-ferrous, non-fluorescent, and moderately reflective materials common in jewelry and dental labs: cast gold/platinum alloys, stainless steel findings, resin-printed prototypes, gypsum dies, silicone impressions, and sintered zirconia blanks. Matte surface preparation (e.g., light talc or anti-reflective spray) is recommended for highly polished metals but not mandatory due to adaptive exposure control. The system complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge and RF fields), and supports GLP-aligned documentation protocols when integrated with validated third-party software for traceable measurement records.

Software & Data Management

The included REXSCAN software provides real-time point cloud visualization, automatic mesh generation, hole-filling, smoothing, and deviation analysis against reference CAD models. All processing steps are logged with timestamped audit trails, supporting FDA 21 CFR Part 11-compliant environments when deployed with electronic signature-capable enterprise systems. STL exports include metadata headers indicating scanner model, firmware version, calibration date, and operator ID — facilitating ISO 13485 traceability in medical device prototyping workflows. Batch export scripting and command-line interface options enable integration into automated digital workflow pipelines.

Applications

• Jewelry CAD reverse engineering: Digitizing legacy hand-carved wax models or antique pieces for archival, replication, or modification.
• Dental crown & bridge design: Capturing prepared tooth anatomy and adjacent dentition with sub-50 µm surface fidelity for margin line detection and occlusal fit validation.
• Investment casting pattern verification: Comparing scanned wax or resin patterns against nominal CAD to identify shrinkage, distortion, or gate-related deformations pre-casting.
• Quality assurance of micro-milled components: Measuring dimensional conformity of small-batch metal parts with complex freeform surfaces where CMM probe access is impractical.
• Educational metrology training: Teaching optical triangulation principles, point cloud registration, and mesh topology fundamentals in university-level materials science and industrial design labs.

FAQ

Is the REXCAN DS2 suitable for scanning transparent or black objects?
Yes — its adaptive white-light exposure algorithm and dual-view geometry allow effective capture of semi-transparent resins and matte-black ceramics without surface coating. Highly reflective metals may require minimal anti-glare treatment for optimal signal-to-noise ratio.
Does the system support automated calibration verification?
Yes — built-in reference target recognition enables daily geometric calibration checks using NIST-traceable ceramic spheres (optional accessory); results are saved in CSV format for trend analysis.
Can multiple DS2 units be synchronized for larger object scanning?
No — the DS2 is a single-unit, fixed-benchtop system. For oversized objects (>100 mm), photogrammetry-assisted multi-station alignment is recommended using third-party software.
What is the typical post-processing time per scan?
A full DS2-L volume scan (≈1.2 million points) requires ≈8–12 seconds for acquisition and ≈15–25 seconds for mesh generation on a Windows 7 system with Intel i7-4790K and 16 GB RAM.
Is technical support available outside Korea?
Yes — Solutionix authorizes certified service partners in North America, EMEA, and APAC regions for hardware maintenance, firmware updates, and application-specific training aligned with local regulatory expectations.
