3D scanner is a data acquiring device. There are multiple data types involved in 3D scanning and users may be confused by all the filename extensions. What is an ASC file? Which file should I export into other software? In this post, we will discuss all file types which involve Einscan software.

There are a total of 6 types of output data format (ASC, p3, STL, PLY, OBJ, 3MF) that you can export from EinScan software during data capture and generating mesh. 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 generate a point cloud, 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 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.

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 format for post processing and measurement.

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.

So that's it!  You have 6 output formats to choose from and all the associated files of your project will be saved in a project group folder.  Remember, these file sizes are large, so make sure you secure a space on your PC where you can save the files.

With the latest  EinScan HX v1.2.0.2 software update, a new mesh editing function has been added.

Unlike other post-process function which only do a single operation, the new “Mesh Optimization” feature in EinScan HX software allows you to do both smooth and sharpen concurrently which will eliminate surface noise while keeping sharp details. You can choose the optimization intensity from 0 to 100%. You  can do multiple iterations if not satisfied with current outcomes.

This function performs well when the original data has a small point distance. For example, here’s a part of the tires scanned with 0.2mm resolution.

We get asked this question a lot. That's why we are here to help.  It's not easy to choose a 3D scanner that needs to capture different sizes, surfaces, shapes and textures. It also depends on your budget.  The difference in price comes from different components such as the camera lens, projector, light source, and software complexity. 

Let's outline 4 important features you need to understand to decide which model would be most suited for your project.

1. Light Source - Structured Light Or Laser?

Accuracy

The accuracy gives an information about the authenticity of a 3D model to the real object. Knowing the accuracy of your scanner is very important because it determines which model is most suitable for quality inspection, reverse engineering design, medical health, or any other applications with very rigid accuracy requirements. Usually, the higher accuracy the scanner is able to generate, the more applications it could be suitable for, and of course, the higher the cost.

Remember though, not all 3D scanning projects require the highest accuracy, so consider your budget and requirements to make a decision on which model to purchase. The accuracy used in the specifications of the scanner usually refer to the accuracy of a single scan. The volumetric accuracy refers to the relationship between 3D data accuracy and object size; with EinScan Pro Series the accuracy is reduced by 0.3mm per meter. This data is based on measuring the center of sphere with marker alignment. The volumetric accuracy of EinScan HX in laser mode is 0.06 mm per meter.

With EinScan handheld 3D Scanners the Pro Series and the H series, the resolution can be changed depending on the object size to ensure the 3D scan data size is manageable. 

3.  Scan Speed

Scan speed is a specification that definese how long it takes to scan one given object. It especially matters when you are going to scan the human body, as people can not stay still for a long time, and it also helps to improve the work efficiency when you are 3D scanning large objects like cars, buildings, etc. Scan speed can be defined by the number of points collected per second, frames per second, or how many seconds it takes to do a single scan. The more points or frames collected per second, the faster the scan speed.

4. Desktop or Handheld

Desktop 3D scanners are provides higher accuracy and enables automation of the whole 3D scan process. The EinScan Pro series handheld 3D scanners can be turned into a desktop/fixed 3D scanners with the Industrial Kit.  For 3D scanning larger objects (like humans or cars), using the handheld 3D scanner is the only solution.

Here is a comparison at a glance.

Accuracy Comparison

In reality all of the above models have similar accuracies. 
EinScan Pro HD and EinScan Pro 2X 2020 both have the same accuracy of 0.045mm in Handheld HD mode, while it is 0.05mm for EinScan H in body and standard mode, and 0.04mm for EinScan HX in laser mode. So accuracy might not be a critical parameter for you to choose a proper device among EinScan series. If high accuracy is a top priority on your agenda, EinScan HX is the best choice among all EinScan scanners. 

Resolution Comparison

EinScan Pro Series (2X 2020 & HD) achieves a higher resolution compared to EinScan H series.  Resolution captured by EinScan Pro 2X 2020 is marginally higher than the Pro HD due to the single scan range being smaller.

​The EinScan H series have a different projecting pattern to the Pro Series thus the resolution is lower. But remember, the EinScan HX can achieve a higher accuracy vs. the Pro Series.

To compare the speed of scanners, two facts need to be considered: single scan range and the points captured per second.

For points captured per second, in Handheld Rapid mode, all scanners of the EinScan Pro Series come with the same speed of 1,500,000 points/s. However as the EinScan Pro HD has a larger single scan range, it can scan large objects at a faster speed. EinScan H (standard scan&body scan) and EinScan-HX (rapid scan) come with the same scan speed in terms of points captured per second and scan range, which are all faster than Pro series. In the face scan mode of EinScan-H, the maximum scan range could reach 780mmx 900mm enabling a fast scan.

Hope this answers many of the questions you may have had!

eviXscan 3D FinePrecision is an optical measuring device operating with blue LED light source. The scanner equipped with two fast 8.9 Mpix cameras of the latest generation with CMOS matrices is characterized by high accuracy of reproduction of even the smallest elements of precision mechanics. FinePrecision technology enables to achieve an accurate measurement of the dimensions of the scanned object (accuracy better than 6 µm, repeatability less than 3 µm). The detail of the scans obtained results from high density of recorded points (more than 1200 points per square millimeter of the scanned surface). A single scan can collect measurement data from a volume of 120 mm x 60 mm x 45 mm.

The advantage of the eviXscan 3D FinePrecision scanner is the short scanning time. The combination of high-speed cameras and the modern DLP light projection system, whose signal triggers the cameras every time a new pattern is displayed, reduces the scan acquisition time to several hundred milliseconds.

FinePrecision scans with high level of detail which is crucial when measuring elements of precision mechanics (micro rotors, small plastic elements made by injection molding, objects manufactured on CNC machines or by 3D printing). The scanner allows also precise 3D scanning of sharp-edged tools or components. FinePrecision can also be used in the scanning of implants, in prosthetics as well as in jewelry manufacturing and watchmaking industry. Its precision enables its use in the optimization of the 3D printing process.

– Based on experience with our Heavy Duty scanners and discussions with our customers indicating areas where precise measurement and very detailed surface mapping was needed, we defined the requirements for a scanner that is a solution for these unfulfilled needs – said Kamil Góra, Product Manager of 3D Scanners in Evatronix. – According to these requirements our R&D department developed a product ready to meet everyday challenges of metrology labs with measurement of fine mechanics objects. Using cameras and projector optimized specifically for our scanner, allowed us to offer a product adjusted to the needs of its future users, really a scanner “from engineers for engineers”.

eviXscan 3D FinePrecision can also be used in the field of predictive maintenance. The identification of microdamage to key components of production equipment (e.g. turbine blades) helps to prevent potential failures, which in turn reduces costs of downtimes.

Fine Precision scanner is available for demonstration and ordering now with first deliveries planned for the second half of March 2021.
