LET'S TALK ABOUT 3D SCANNING

Sometimes, simply laying out the key specifications side by side makes it much easier to decide which 3D scanner best suits your needs.
To save you time and effort, we've put together a comprehensive comparison of 3D scanner models below!

According to Google Gemini:
When comparing the Go Scan Spark, Artec Eva, and EinScan HX 2, the key differences lie in their scan speed, accuracy, and ideal application areas, with the Artec Eva generally considered faster for capturing textures on larger objects, the EinScan HX 2 excelling in high-resolution detail capture, and the Go Scan Spark offering good accuracy and portability for a wider range of applications. 

According to Chat GPT: 
EinScan HX2 stands out for its hybrid scanning technology, providing high accuracy and versatility across various surface types. The Artec Eva and Creaform Go!SCAN SPARK are both efficient structured light scanners, with the Eva excelling in speed and the Go!SCAN SPARK offering a balance between precision and user-friendliness.

According to Growshapes :) :
You get the best bang for you bucks with the EinScan HX2. EinScan HX2 starts from $9,999 while Artec Eva from $19,800 and Go!Scan SPARK from $35,645. Why not check the EinScan HX2 out?

Also if you want to save a bit and buy the previous HX model on sale! HX is a bit slower in scan speed and less laser lines but provides the same high accuracy output!

EinScan-SE/SP V2 offers enhanced user experience compared to its predecessors and what's more now it's compatible with macOS!  The 3D scanning world has been predominantly Windows compatible, but now you have the option to use with your macOS.

Enhnaced 3D scanner features: 

• Faster Scanning Speed: Compared with EinScan-SE/SP, EinScan-SE/SP V2 has greatly improved the scanning speed. Only 1 second for a single scan, 45 seconds for a 360-degree scan under auto scan mode.
• Wide Scanning Range: The EinScan-SE/SP V2 offers a wide scanning range, accommodating small and large objects. Whether capturing intricate details or scanning large structures, this scanner delivers unparalleled versatility.

macOS compatible EXSCAN S software offers the following features.

• Intuitive Trackpad Gestures: EXScan S_v3.2.0.1 supports macOS trackpad gestures, making the 3D scanning process more intuitive and efficient. Now, you can easily navigate and manipulate your scans at your fingertips.
• Background Cutting Function: Automatically blocks unwanted backgrounds for impeccable scanning results. EXScan S_v3.2.0.1’s background cutting feature simplifies the post-processing stage, saving you time while ensuring exceptional results.
• Quick Alignment: This function will align the object with the coordinate frame based current view: the z-axis is up, the x-axis is toward outside of the screen, and the y-axis is right. The coordinate frame will be in the center of the object bounding box.
• Updated UI Interface: EXScan S_v3.2.0.1 receives a fresh and modern UI interface with new editing tools, providing a more visually appealing and user-friendly experience.
• Various Align Modes: Empowers users with options, EXScan S_v3.2.0.1 still offers various align modes to suit different scanning scenarios, but with a more intuitive way to select align modes. Selecting a suitable align mode for different scanned objects will help you get data efficiently.

In 3D scanning, accuracy is a key metric in choosing which model to use for your project. 

How accurately do you need to replicate the physical model? In other words, how authentic do you want the 3D digital model of the real object to be?

High end 3D scanners like eviXscan Quadro+ can achieve up to 0.007mm (7 microns) accuracy, while lower end 3D scanners like EinScan SP can still achieve an accuracy up to 0.05mm (50 microns). Accuracy of a 3D scanner depends on the quality of the camera, projector lights as well as the software.

Meanwhile there is another important metric, resolution.  Resolution is about defining the point distance the 3D scanner can capture to generate the point cloud which is then converted into a mesh.  If you 3D scan your object in high resolution, the point distance is small thus details will be more visible, while if you 3D scan your object in low resolution,  the point distance is bigger.

Below is a guideline of resolution settings that is optimal depending on the type of objects you are 3D scanning. Basically the recommendation is the smaller the object, use high detail (higher resolution) and the larger the object, use low detail (lower resolution) settting.

The Einscan Pro HD and EinScan 2X 2020 provde super high resolution with HD scan mode and setting the resolution to "High Detail".  This kind of high detail captures is useful for objects with that has a lot of details like the object below.  On the other hand, large engineering parts may not require such detail but higher accuracy.

Basically the tip is to think about what you are going to do about your 3D scan file and choose the right resolution setting depending on the object you are 3D scanning.

Structured light 3D scanners use the projector light to project structured light patterns onto your target object, while the cameras capture the change in the structured light patterns and the 3D scan software generates the 360 degree digital surface model of your target physcial object. Therefore, for any structured light 3D scanner, adjusting the 3D scanner projector brightness level is very important. This enables the 3D scanner to project the sturctured light pattern adequately to capture the surface dimensions of the target object.

See below for guidance.

It is important to adjust your distance between the 3D scanner and the target object as well as the brightness.

Make sure you get the hang of the correct brightness as well as the distance between the object and the 3D scanner, so your 3D scanning process will proceed smoothly!

1. Trim Mesh with Plane/Curve

Several options are available that allow you to trim (remove) polygons from an object. These options can all be accessed via the Trim button.

EinScan H users, download the latest software version V1.0.5.3 Exscan H that enables the capture of fine details when using Infrared Scanning, Face Scan Mode.

With the newly developed algorithm, the software can capture more details around the face with invisible Infrared light. Check out the details below.

EinScan H is also useful in making 3D digital replicas of ancient artifacts which may be sensitive to white light.

​The combination of great hardware and software truly makes a difference in how much detail can be captured with 3D scanning technology. The team behind EinScan 3D scanners continues to innovate pushing frequent software updates and develping new software algorithms, so make sure you have the latest software to get the benefits of all the new features!

EinScan HX
​
The new EinScan HX combines blue laser and blue light in one unit that enables 3D scanning of reflective and dark surfaces with high accuracy. ​

There are many factors to consider when selecting a 3D scanner.  What is your budget, what are you trying to scan, are you trying to scan quickly, do you need color texture, do you want high resolution as well as accuracy?  Which technology is best? What are you going to do with the 3D scan files?

Growshapes is focused on distributing structured light 3D scanners which project light patterns onto an object to capture the surface measurement. It scans a whole dimension, so it is quick. But even within the structured light 3D scanner category, there is whole range from low, mid to very high end with different manufacturers offering different hardware and software capability.

To help you figure out which 3D scanner best serves your objective,  we created a quick comparison of the 3D scan file of EinScan SE, EinScan Pro 2X and HP Pro S3.  Each 3D scanner has its Pros and Cons and it really depends on how much you want to spend and what you want to achieve.  So, download the file below and see if this helps you in your decision making. 

If you have realized that you need much more high resolution and high accuracy 3D scanning capabilities, definitly go for the more expensive industrial-grade eviXscan Heavy Duty Quadro.  The hardware and software is much more advanced.

3D scanner is not a "one-size-fits-all" type of tech product.  It's horses for courses for sure.
