What Is the FreeScan Combo?

Overview

The FreeScan Combo is a hybrid metrology 3D scanner that combines two scanning modes in a single portable unit: laser line scanning for high-resolution geometry capture, and infrared scanning for faster coverage of larger or simpler surfaces. This dual-mode capability is the Combo's defining feature. It switches between scanning modes to match the task at hand, which makes it the most flexible tool in the FreeScan portfolio.

Key Features

• Hybrid scanning modes: Switch between laser line scanning (high detail, complex geometry) and infrared scanning (fast, efficient for larger surfaces) within a single session

• Metrology-grade accuracy: Delivers the precision required for GD&T inspection and reverse engineering across a wide range of industrial part types

• Handheld portability: Compact and lightweight for single-operator deployment in the lab, on the shop floor, or in the field

• Flexible working range: Optimized for small-to-medium parts, with sufficient range to handle larger components when required

• Software compatibility: PolyWorks Inspector, Geomagic Control X, SolidWorks Inspection

Best Use Cases

• Reverse engineering: Converting scanned parts into CAD models for legacy component recreation, design updates, or prototype-to-production conversion

• Mixed inspection workflows: Teams that inspect a range of part types in a single shift, from small precision machined components to larger cast or welded assemblies

• Field deployment: Portability makes it practical for on-site scanning of installed components, large assemblies in fixed positions, or supplier audit visits

• Automotive component engineering: Scanning brackets, housings, interior trim components, and prototype parts across a range of automotive part sizes

What Is the FreeScan UE Pro 2?

Overview

The FreeScan UE Pro 2 is a high-efficiency multi-line laser scanner optimized for large-scale industrial scanning. Where the Combo prioritizes flexibility, the UE Pro 2 prioritizes throughput: scanning large parts faster, covering more surface area per pass, and delivering consistent metrology-grade results on large industrial components that require extended working distance and wide scan coverage.

It's a common choice for automotive Tier 1 suppliers, aerospace component manufacturers, and heavy industrial QA teams that routinely inspect large castings, stampings, body panels, and structural assemblies.

Key Features

• High-speed multi-line laser scanning. Multiple simultaneous laser lines capture significantly more surface area per pass than single-line systems, directly reducing scan time on large objects

• Large object capability. Extended working distance and wide field of view optimized for medium-to-large industrial parts, including body panels, engine blocks, tooling, and large castings

• Stable metrology performance. Consistent accuracy across large surface areas, including parts with complex curvature and deep features

• High-throughput QA workflows. Designed for production environments where inspection cycle time directly impacts manufacturing throughput

• Software compatibility. PolyWorks Inspector, Geomagic Control X, SolidWorks Inspection

Best Use Cases

• Automotive body panel and structural inspection. Body-in-white verification for OEMs and Tier 1 suppliers, full-surface deviation analysis of stamped panels against CAD nominal

• Large powertrain component QA. Engine block and cylinder head inspection where large machined surfaces must be verified against tight tolerances across the complete part

• Tooling and mould validation. Scanning injection moulds and stamping dies to detect wear and dimensional drift before scrap rates increase

• High-volume production QA. Teams running 50 to 200+ inspections per day who need maximum throughput from the scanning hardware

• Aerospace structural components. Large bracket and panel inspection for aerospace supply chains

Feature Comparison: FreeScan Combo vs FreeScan UE Pro 2

Scanning Technology

This is the foundational difference between the two scanners. The FreeScan Combo uses a hybrid approach, combining laser line scanning with an infrared scanning mode that can be selected based on the task. This gives operators the ability to prioritize either fine geometric detail (laser mode) or rapid surface coverage (infrared mode) within the same scan session. Shining3D describes this hybrid capability as the Combo's defining feature for multi-workflow deployments.

The FreeScan UE Pro 2 uses a high-density multi-line laser configuration, with multiple simultaneous laser lines that cover wider surface areas per pass without switching modes. This single-mode, high-efficiency approach is optimized for the consistent large-scale scanning scenarios where the UE Pro 2 is intended to perform best, rather than the adaptive flexibility that the Combo provides.

Accuracy and Resolution

Both scanners are metrology-grade. They deliver the dimensional accuracy required for GD&T inspection, first article verification, and reverse engineering across industrial manufacturing applications. The accuracy specifications of both systems are suitable for automotive, aerospace, and general manufacturing quality control.

For precision machined components with tight tolerances, both scanners are appropriate. The choice between them on accuracy grounds alone is not the primary decision driver; workflow fit is.

Scan Speed

The FreeScan UE Pro 2's multi-line laser configuration gives it a speed advantage on large, relatively simple surfaces, since it covers more area per second than the Combo when operating in laser mode. For large body panels, structural castings, and similarly expansive geometries, the UE Pro 2 consistently completes scan sessions faster.

The Combo's speed advantage is in its flexibility. The infrared mode offers fast surface coverage for simpler features, allowing operators to switch to the faster mode mid-session when appropriate. For smaller parts or complex features, the speed difference between the two scanners is minimal.

Working Distance and Part Size

The FreeScan Combo is optimized for small to medium parts, the range that covers the majority of reverse engineering applications and a large proportion of QA work. It can handle larger parts, but its efficiency advantage is greatest in the small-to-medium range.

The FreeScan UE Pro 2's extended working distance and wider scan footprint make it significantly more efficient on larger industrial components. Teams that regularly scan parts in the 500mm to 2000mm+ range will find the UE Pro 2 completes those scans faster with fewer repositioning steps.

Portability

The FreeScan Combo is the more portable of the two systems: lighter, more compact, and better suited to single-operator deployment in variable environments such as the shop floor, field service, supplier audits, or scanning installed assemblies in situ. For teams that scan in multiple locations or need to carry equipment to the part rather than the part to the equipment, the Combo's portability is a practical advantage.

The FreeScan UE Pro 2 is portable in the sense that it's handheld, but its optimized performance is in a more controlled setup, such as a production QA station, a dedicated inspection area, or a fixed scanning cell. It's not the natural choice for frequent travel or single-operator deployments in constrained environments.

Ease of Use

Both scanners are designed for industrial operators rather than specialist scanning technicians. Neither requires weeks of training to reach productive daily use. The Combo adds the decision of which mode to use for each surface, a minor cognitive step that new operators resolve quickly with experience.

Use Case Comparison: Which Scanner Fits Which Workflow?

Reverse Engineering

For reverse engineering workflows, converting scan data into manufacturable CAD models, the FreeScan Combo is the more flexible choice for most RE engineers. Its hybrid modes handle the range of part types that typically appear in an RE workload: precision machined components, cast housings, plastic injection-moulded parts, and fabricated assemblies.

The FreeScan UE Pro 2 is a strong RE tool for large parts. If your RE work is primarily focused on large castings, body assemblies, or structural components, the UE Pro 2's extended range and faster coverage of large surfaces makes it the more efficient choice for that specific application.

Quality Control and Inspection

For production QA workflows, including scan-to-CAD deviation analysis, first article inspection, and GD&T reporting using PolyWorks Inspector or Geomagic Control X, the choice depends on part size.

For small-to-medium precision parts, both scanners perform the inspection workflow well. For large parts, such as automotive body panels, large castings, or structural components, the FreeScan UE Pro 2's throughput advantage on large surfaces makes it the more productive QA tool.

Large-Scale Industrial Scanning

For automotive Tier 1 suppliers inspecting stampings and body assemblies, for heavy manufacturing teams validating large castings, or for any production environment where scan objects regularly exceed 500mm in their largest dimension, the FreeScan UE Pro 2 is generally the better-optimized choice, since its multi-line laser configuration is designed for this scale. This is the type of workflow where the UE Pro 2's throughput advantage tends to create a measurable impact on inspection cycle time, particularly for high-volume automotive OEM and Tier 1 supplier production quality operations.

Mixed Workflows

Many industrial engineering teams don't work on a single part type. A day's work might include scanning a small precision gear, a medium cast housing, and a large structural weldment. For this kind of mixed-workflow environment, the FreeScan Combo is generally the better choice, since its hybrid modes and performance across a wider size range make it the more productive tool across the variability of a real workday.

Use Case Fit Summary

ROI Comparison: An Engineering Manager's Perspective

Both scanners deliver comparable ROI outcomes for industrial metrology scanning, typically a 2 to 5x reduction in inspection time compared to manual methods, a 40 to 70% reduction in scrap and rework, and a 6 to 12 month payback period. The ROI difference between the two products isn't in the magnitude of these outcomes but in which workflow generates them most efficiently.

Time Savings

For teams where large-part inspection is the primary workload, the FreeScan UE Pro 2's scan speed on large surfaces directly reduces inspection cycle time, and reduces it more than the Combo would in the same application. If your inspection bottleneck is the time to capture a complete body panel or large casting, the UE Pro 2 addresses that bottleneck more directly.

For teams with mixed workloads, the Combo's hybrid flexibility produces consistent time savings across all part types. No single scan type gets disproportionate efficiency gains, but overall throughput improves across the board.

Cost Reduction

Both scanners reduce scrap and rework costs by catching dimensional non-conformances earlier in the production cycle. The earlier in the process a deviation is caught, at first operation rather than final inspection, or before an assembly step rather than after, the lower the cost of correction. Both systems support this shift from end-of-line to in-process inspection for teams willing to invest in the workflow change. For automotive suppliers managing OEM-level production quality requirements, the scrap reduction from comprehensive in-process inspection, enabled by either scanner, is typically the primary ROI driver.

Productivity Gains

The FreeScan UE Pro 2 generates larger per-session productivity gains on large parts: fewer scan positions, faster coverage, shorter cycle time per part. For production QA environments running 100+ large-part inspections per week, this per-inspection time saving compounds into meaningful weekly and monthly capacity.

The FreeScan Combo generates productivity gains across a broader range of task types, including RE sessions, varied inspection runs, and field scanning, which can add up to a comparable overall productivity impact for teams with diverse workloads.

Common Mistakes When Choosing Between These Scanners

Choosing Based Only on Specifications

Both scanners are metrology-grade. Their headline accuracy numbers are comparable, and neither has a decisive specification advantage over the other in the metrics most buyers focus on first. Teams that compare only specification sheets frequently end up choosing based on minor differences in quoted accuracy or scan speed that have no practical impact on their workflow. The meaningful decision criteria are workflow fit, part size, and deployment environment, not the specification comparison.

Ignoring Workflow Needs

The most useful question isn't "which scanner is more accurate?" but "which scanner matches how my team actually works?" A team that scans three different part types per day needs a different tool than a team that runs the same large casting inspection 200 times per week. Map your actual daily workflow, including part sizes, task types, and deployment locations, before evaluating scanner specifications.

Underestimating Object Size as a Selection Factor

Part size is an underrated decision factor in scanner selection. Teams that primarily scan parts over 500mm and choose the Combo will find it capable but not optimally efficient. Teams that primarily scan small-to-medium parts and choose the UE Pro 2 will find it more powerful than necessary for their needs. Being honest about your production environment's actual part size distribution is one of the most reliable predictors of which scanner will deliver the best workflow efficiency.
