LET'S TALK ABOUT 3D SCANNING

EinScan 3D Scanner File Types 101

3/15/2022

0 Comments

 
3D scanner is a data-acquiring device that captures the surface model of a physical object in a digital polygonal model. The types of output data format that 3D scanners can generate maybe confusing. What is an ASC file? Which export formats does my CAD software import for rapid prototyping? What is the best practice for saving scans? Which file format is the best choice for 3D printing?  In this post, we will discuss all file types that involve Einscan software.

The type of file you require depends on what you are going to do after the scanning process. There are a total of 6 types of output data formats (ASC, p3, STL, PLY, OBJ, 3MF) that you can export from EinScan software during data capture and generating mesh which are polygon models. We will explain the differences among these 6 file types in this blog.

Point Cloud Data Format

When you have finished your scan and are ready to convert your raw scan data to point cloud data, you can click on the save button to save the point cloud data as an ASC file and the marker position as p3 format when markers are detected.

ASC file contains the position information of each point in the point cloud. This file type can be opened in most scan data processing software and metrology software like Meshmixer, GOM Inspect, and Geomagic Essentials.

The P3 file is for marker reuse purposes in EinScan software. For a large object scan, the user can scan all markers only first and save the marker frame as a p3 file. Later the object can be scanned part by part in a separate project using the same p3 file as a reference which improves the accuracy and will require no alignment between each project.

With Fix scan mode number of scans will be saved as separate files, while for handheld scans the full point cloud will be saved as one file.

Meshed Data File Format

After the data is meshed, more saving options will be available. ASC file is still available while the mesh can be saved as STL, PLY, OBJ, or 3MF files.

STL file format is the most common mesh file format. It only contains the position and normal directions of all triangles in the mesh. This polygon file format can be opened by mesh editing software and many CAD software like Solid Edge or Solidworks for reverse engineering.

PLY and OBJ file formats contain mesh texture information, including color information, in addition to the STL file. Users can export these data types for digital documentation and online model display.

3MF file is the 3D printing format published by the 3MF Consortium. This format includes information about materials, colors, and other information that cannot be represented in the STL format. Windows system and other CAD software packages can open this mesh format.

Post Processing Data
​

EinScan software provides basic functions for mesh editing in Post Processing and Measurement sections. Usually, users use these functions right after meshing data. However, external mesh data can also be imported into the EinScan software for editing. The EinScan software supports STL, OBJ, and PLY formats for post-processing and measurement.

Saving Data in Project Group

The 3D scan data in the EinScan software are saved for later use in a two-layer structure. When the user starts a new scan,  a new project group is created. All the associated files in the project group will be saved as a project under a folder named by the project group.

The project group folder contains different kinds of files. The project group directory links all projects in the group. The project directory links all data files belonging to this project and the rest are project data files. When moving the project group, the user needs to move all the folders in the project group. 

When opening the project, the user needs to locate the folder where the project group was saved and open the corresponding directory files.The project group folder contains different file formats. The project group directory links all projects in the group. The project directory links all data files belonging to this project and the rest are project data files. When moving the project group, the user needs to move all the folders in the project group. 

When opening the project, the user must locate the folder where the project group was saved and open the corresponding directory files.

So that's it!  You have 6 output formats to choose from and all the required scans for your saved project will be in a project group folder.  Remember, the file size for each project is large, so make sure you secure a space on your PC where you can save the files.
