01
Surface preparation
Clean the part: foreign particles may enter the point cloud and distort its geometry. Position it so the required surfaces can be accessed. The MVP materials show the casing used in the subsequent scan and comparison.
01
Product and MVP
We are developing software for three-dimensional product quality inspection. It compares manufactured part geometry with design requirements and records deviations.
The intended setting is production and warehouse operations. The target solution combines contact measurements and 3D scanning, data processing and comparison against drawings, models and sketches.
The MVP workflow has been tried on a real part: preparation, scanning, processing, model work and comparison. Measurement accuracy, integrations and automated reports still require separate validation.

The inspection sequence
02
Markers and equipment
Place markers irregularly on the part or work area to track the scanner. The pattern depends on the equipment and mode. This MVP used a Creality CR-Scan Raptor; marker-free operation depends on the scanner and measurement task.
03
Geometry capture
Scan in Creality Scan while checking coverage and working distance. The green indicator zone guided the operator in this process. The scanner–computer–part workflow was tried on a real example.
04
Point cloud processing
Remove the table, support and other unwanted fragments. Select the resolution, clean the data and build a polygon mesh for further analysis.
05
Transfer to CAD
Transfer polygon geometry to CAD or measurement software in supported formats such as STL or OBJ. STEP may require CAD geometry reconstruction and depends on the tools used. Continue modelling, analysis or reverse engineering.
06
Comparison with the reference
Align the captured geometry with the reference and analyse deviations. Project materials include a CAD model and comparison using KOMPAS-3D. A conformity decision requires defined tolerances, an agreed method and validated measurement uncertainty.
03
What has been tried and what comes next
Practical workflow
Equipment, capture, processing and comparison with a reference model on a real part.
MVP evidence
Work photos, digital geometry and comparison screens document practical work.
Next step
Validate repeatability and acceptable uncertainty; develop integrations, operator interface and result documentation.
The target is to record measurements and issue conformity or nonconformity reports. Automated report creation and export are product development objectives.
04
Product requirements
Reliability
Stable measurements, preserved data and repeatable reference comparison.
Usability
A clear interface and short operator preparation for shop-floor and warehouse use.
Speed
Acquire and process data with fewer manual actions.
Accuracy
Compare against design documentation within validated allowable uncertainty.
Online and offline
Direct transfer or autonomous work followed by synchronisation are target modes.
Documentation
Conformity reports, result history and export of measurement protocols.
These are requirements for the evolving software, not a substitute for metrological validation or a specification of a finished industrial system.
