How to 3D Scan an Object

Aug 21, 2023

For many starters in 3D scanning, the first question they are faced with might be “How to 3D Scan an Object”. To 3D scan an object, you’ll need a 3D scanner and appropriate software.

Scantech provides a general step-by-step guide to help you get started:

Choose a 3D Scanner:

Select a 3D scanner based on your needs. There are various types, including handheld 3D scanners, tracking 3d scanners(3d optical measurement system), and automated 3D system. Consider factors such as the object’s size, complexity, and level of detail you require. Opt for handheld 3D scanners when dealing with small objects requiring high precision. Choose tracking 3d scanners for big objects to ensure comprehensive scans. For tasks involving mass production, automated 3D systems are the ideal choice to streamline the process efficiently.

Choose a 3D Scanner

Prepare the Object:

Scantech’s 3D laser scanners offer versatile scanning capabilities, allowing you to 3D scan objects anytime and anywhere, without being constrained by environmental limitations.

Position the Scanner:

Follow the Scantech’s instructions to set up the scanner. Position it at an appropriate distance and angle from the object. Scantech 3D object scanners employs a green light belt to indicate the correct positioning. Some scanners require specific markers or targets to aid in alignment, while our 3D scanners such as TrackScan-Sharp 3D System, and iReal M3 Color 3D Scanner offer a markerless alignment approach.

Capture the Scans:

Begin capturing scans by following the scanner’s instructions. Most scanners require you to move the scanner around the object to capture multiple viewpoints. Overlapping scans help create a complete 3D model.


Once you’ve captured the scans, import them into the accompanying software. Align and merge the scans to create a unified point cloud or mesh. Use the ScanViewer 3D Software‘s editing tools to clean up any artefacts or imperfections.


Generate the 3D Model:

Convert the aligned scans into a 3D model. Depending on the software, this could involve creating a mesh, surface, or solid representation of the object.

Refine and Export:

Fine-tune the 3D model, adjusting settings for texture, resolution, and accuracy. Once satisfied, export the model in a suitable file format, such as STL or OBJ.

Optional: Post-Processing Software:

For more advanced editing and refinement, you can import the exported model into 3D modelling or CAD software. This allows you to make further modifications, add textures, or prepare the model for 3D printing.

Use and Share:

Your 3D scan is now ready for use in various applications, such as design, analysis, or 3D printing. You can also share the 3D model with colleagues or clients.
