Introduction: From sand-mold inspection for oilfield equipment to cutting propeller repair cycles by 20%, FreeScan Combo has demonstrated the practicality of metrology-grade handheld scanning in factories and outdoors through its compact dual-light-source, multi-mode design.
On October 19, 2026, Nanjixiong learned that SHINING 3D had officially launched the FreeScan Combo Wireless series, moving this established product line from wired to wireless and reducing body weight from 620 g to 550 g. This is more than a simple specification update; it is a systematic redesign centered on freedom of measurement in the field.
Wireless transmission and a 550 g ultralight body: measurements can truly be taken anywhere
The most obvious change in the FreeScan Combo Wireless series is the complete removal of cables and the base station.
The device has an embedded wireless transmission module and built-in battery. Scanning requires no separate detachable base, enabling truly untethered operation. For engineers working around large parts, in confined spaces or outdoors, the scanner is no longer "tied" to a computer by a data cable, representing a substantial improvement in operating freedom.
Weight and size improvements are just as important. The scanner weighs only 550 g—about as much as a bottle of mineral water—and measures 189 × 81 × 53 mm. It is approximately 11% lighter than the previous generation's 620 g. More importantly, fatigue from holding it for extended periods is significantly reduced, and working inside narrow spaces and complex structures becomes easier. Three batteries are included for rotation, and an external power bank is supported for long, uninterrupted scanning sessions.
Metrology-grade accuracy of 0.015 mm: going wireless does not mean cutting specifications
A common concern with wireless operation is whether accuracy is sacrificed. The FreeScan Combo Wireless series says no.
As products under SHINING 3D's SHINING 3D Metrology brand, they retain stringent metrology standards. FreeScan Combo+ Wireless offers accuracy up to 0.015 mm, while FreeScan Combo Wireless offers 0.02 mm. The series can be paired with the company's proprietary industrial 3D inspection software, which has dual accuracy certification from Germany's National Metrology Institute (PTB), supporting compliance requirements for industrial 3D measurement and inspection.
The series also integrates VPG large-volume video photogrammetry. It quickly captures a large number of images through video streaming to ensure overall volumetric accuracy on medium and large parts, without requiring coded targets, further simplifying field operation.
Dual light sources and five modes: one device for a range of applications
The FreeScan Combo Wireless series combines blue laser and infrared VCSEL light sources in a compact body and offers five switchable measurement modes. The FreeScan Combo+ Wireless provides:
High-speed scanning: 93 crossed blue laser lines for quickly capturing large areas such as automotive body panels and large molds.
Fine scanning: 25 parallel laser lines for reproducing details in complex structures.
Deep-hole scanning: a single laser line reaches into holes and grooves to capture three-dimensional data in deep cavities.
Scanning without targets: infrared VCSEL enables rapid scanning of surfaces with rich geometric features without attaching targets.
Photogrammetry: built-in binocular photogrammetry, combined with VPG video streaming, helps ensure accuracy on large parts.
The series scans at up to 9,106,000 points per second and generates meshes in real time, eliminating the post-processing time needed to package point clouds. This is a leading speed among metrology-grade handheld devices, further reducing the time window needed to capture complete data on site.
Intelligent applications: a seamless workflow from scanning to inspection
The FreeScan Combo Wireless series includes two notable interaction improvements.
Smart buttons: Adjust brightness or switch modes during scanning without returning to the computer interface; a single button press is enough. This reduces interruptions for field engineers whose hands are both occupied operating the scanner.
Smart color mapping: Real-time color maps indicate data completeness, helping operators identify missed areas and ensure complete scanning coverage.
The software uses a guided interface that beginners can learn quickly. After scanning, users can switch to inspection software with one click for 3D comparison, GD&T geometric dimensioning and tolerancing analysis, and other professional applications, then generate a visual inspection report. The process from "capturing data" to "getting a conclusion" is compressed into one workflow.
The wireless FreeScan Combo solves the "last meter" problem
The accuracy competition among metrology-grade 3D scanners has long been measured in micrometers. But actual industrial-site pain points are often absent from a specification sheet: can the equipment be taken to the location where it is needed?
A cable, a base station and a battery that must be changed frequently may seem like minor constraints. Beside a large part, inside a narrow engine compartment or at an outdoor worksite, however, each can cause real efficiency losses. By reducing weight to 550 g, eliminating the cable and base station, and enabling users to rotate among three batteries, the FreeScan Combo Wireless series addresses the freedom needed for that "last meter" from the equipment case to the measurement point.
In earlier coverage of SHINING 3D's upgrades to three FreeScan metrology scanners, Nanjixiong noted that demand in industrial metrology was shifting from "laboratory accuracy" toward "field accuracy." The FreeScan Combo Wireless launch is another example of this trend: when a 550 g wireless device can deliver 0.015 mm metrology-grade accuracy, the boundary between high-precision 3D measurement and on-site work is becoming more blurred than ever.
