What is the accuracy of your 3D scanning system, and how does it compare to CMM?
Our advanced 3D scanning systems deliver exceptional measurement capabilities with specific accuracy profiles that make them ideal for various applications, while coordinate measuring machines (CMM) remain the gold standard for certain critical measurements. The choice between technologies depends on your specific requirements for speed, density, and precision.
Our 3D Scanning System Capabilities
Structured Light Scanning Systems:
Volumetric Accuracy: ±0.025 mm to ±0.085 mm depending on measurement volume
Point Spacing: 0.05 mm to 0.2 mm for high-resolution capture
Point Accuracy: ±0.015 mm to ±0.040 mm per individual measurement
Resolution: Capable of capturing up to 8,000,000 points per measurement
Laser Scanning Systems:
Volumetric Accuracy: ±0.025 mm to ±0.200 mm based on working distance
Measurement Rate: Up to 2,000,000 points per second
Single Point Repeatability: ±0.015 mm under ideal conditions
These systems are particularly valuable for Reverse Engineering and first-article inspection of complex geometries produced through Powder Bed Fusion and Material Extrusion processes.
Coordinate Measuring Machine (CMM) Capabilities
Traditional Bridge CMM Systems:
Volumetric Accuracy: ±0.0015 mm to ±0.005 mm (substantially higher than scanning)
Single Point Repeatability: ±0.0005 mm to ±0.001 mm
Measurement Uncertainty: Typically 1.5-3.0 μm depending on machine class
Sparse Data Collection: Limited to programmed points rather than full surfaces
CMM technology remains essential for validating critical dimensions of precision components made from Titanium Alloy and Stainless Steel for Aerospace and Aviation applications.
Comparative Analysis: Application-Based Selection
When 3D Scanning Excels:
Complex Surface Capture: Organic shapes, freeform surfaces, and intricate details
High-Point Density Requirements: Full-field analysis for Surface Treatment validation
Large Parts: Scanning of automotive panels or aerospace structures
Speed-Critical Applications: Rapid capture of complete geometries in minutes
Soft Materials: Non-contact measurement of flexible components or Plastics
When CMM Delivers Superior Results:
Dimensional Tolerances: Validation of critical holes, planes, and features below 0.01 mm
Reference Measurements: Establishing gold standard for scanner calibration
Hard Probe Access: Internal features easily reached with styli
Stable Environments: Temperature-controlled metrology labs
Simple Geometries: Primarily prismatic features with clear datum structures
Integrated Quality Workflow
Combined Approach for Comprehensive Validation:
CMM for Critical Features: Establish datum structure and measure tight-tolerance features
3D Scanning for Surfaces: Capture complete surface form and complex contours
Data Fusion: Combine both datasets in a common reference frame for a complete assessment
This methodology is particularly effective for Medical and Healthcare components requiring both precise dimensional accuracy and complex anatomical surface conformity.
Industry-Specific Implementation
Automotive Applications: For Automotive components, we typically employ:
Scanning for body panels and styling surfaces
CMM for engine mounting points and critical interfaces
Aerospace Components:
Scanning for turbine blade profiles and airfoil sections
CMM for mounting interfaces and bolt hole patterns
Medical Devices:
Scanning for custom implant surfaces contacting bone
CMM for modular connection features and screw threads
Accuracy Verification and Traceability
Both our scanning and CMM systems undergo:
Regular Calibration: Traceable to national standards
Artifact Verification: Using certified reference standards
Uncertainty Analysis: Comprehensive measurement uncertainty budgets
Interoperability Testing: Ensuring data alignment between technologies
For the highest accuracy requirements, we recommend a hybrid approach that leverages the strengths of both technologies, particularly for components that require both form verification and dimensional validation.
