Einscan Pro 2X vs Pro 2X Plus

May 13, 2020

So you've been looking at 3D scanner and stumbled open the Einscan Pro 2X, and the older wiser sibling the Pro 2X Plus. We get tons of questions about the difference between them, and that's what this post will address. 

Here is a table summary that's available online through our listings: 

Now that I have you confused, let's dive into what these specs and numbers actually mean. 

Scanner Resolution (Point Distance)

A 3D scanner captures points in space. The capture density of these points in a given area of the model is the resolution. More points in a specific volume equal to a better resolution. Think about how an image looks sharper on a 4K monitor versus a 1080p monitor. Take that a step further and look at comparing a 24" 1080p monitor and a 42" 1080p monitor, you'll notice a significant difference in sharpness because the same amount of pixels are stretched to accommodate a larger view. So what does this mean for a scanner exactly? 

Let's say that a scanner can pick up points as close as 0.1mm apart. In a 1inch cube area, we'd be able to pick up roughly 150,000 points. If our scanner resolution is 0.2mm, in the same in cube, we'd be able only to pick up about 80,000 points. That's our 1080p versus 4K comparison. Depending on your application, this fact may have little impact on your final scan. Why? 

If you mainly scan parts that are large and don't have a lot of tiny details, you will not feel the difference between the two resolutions. Think 3D scanning an entire vehicle versus a hot wheels car. You want to pick up as many points as possible on a hot wheels car, but on a front bumper, the difference wouldn't matter all that much. 

Take into account that higher resolution also means larger files to handle. This will take its toll on storage and will test your computer's ability to process data. Please consult the recommended computer configuration for the EinScan Pro 2x and EinScan Pro 2x Plus to ensure compatibility.

Moving on to accuracy

This one is simpler. Are the points being scanned in the correct location like in real life? Higher accuracy means a more true to life scan. The Einscan 3D scanners use structured light to achieve higher accuracy scans versus laser or photogrammetry methods.

 

Scan modes

Handheld Rapid Scan and HD Scan

As you may have understood, these two scan modes are used when the object is stationary, and the scanner is in your hands. You scan the object by moving around it. This mode is best for medium to large objects that don't shift a lot like parked cars, adults, and statues. Not so suitable for cute dogs!

The main difference between the Pro2X and the Pro2X plus here is in HD mode. The Pro2X Plus captures up to 100 data capture lines versus the seven lines on the Pro2X. In other words, the Pro2X plus can process about one million points per second, and the Pro2X can only process 100,000. The Pro2X Plus is taking in a whole lot more detail per shot, allowing you to scan faster and get better overall resolution at the same time. 

 

Fixed Scan Mode (With turntable or without)

Fixed scan mode is useful when scanning small to medium-sized objects with intricate details. 

In this mode, the scanner is placed stationary on a tripod and here the object moves. With the industrial pack, the scanner is connected directly to a tripod and mechanical turntable, allowing you to set how many shots you want to take in one full revolution. On the other hand, you can also use an existing tripod and rotate the object yourself every time you make a shot. There are a couple of differences between the two models: 

Fixed Mode Scan Speed

The scan speed is twice as fast on the Pro2X plus, which, coupled with the automated turntable, can save you quite a bit of time. Setting up the capturing parameters (ex. shots per revolution) and hitting "start scan" is quite convenient. It also removes a ton of human error since there is no manual rotation of the object between shots. 

Single Scan Range

The Pro2X plus can take a bigger picture; in fact, its single scan range is twice as big. Meaning it can take in more points per snapshot. However, this comes at the cost of resolution. The Pro2X Plus point distance in this mode is 0.24mm compared to the 0.16mm of the Pro2X. Depending on your application, this may be a non-factor.

Single Shot Accuracy

The single scan shot accuracy in this mode is the same at 0.04mm.

 

Add on compatibility

There are three add ons available for the Pro2X line: colour pack, industrial pack, and HD prime pack. 

• The Colour pack enables scanning of colours at the same time as you scan your objects. Great for applications involving augmented reality like scanning a shoe and adding it to your website for real 360-degree viewing. Available for both models
  
  
• The Industrial pack adds automation to the scanning process. A tripod and turntable integrate into the scanner seamlessly, allowing for a more natural and smoother scanning workflow. Available for both models
  
  
• The HD Prime Pack allows for marker-free handheld scanning. Generally, if an object is symmetrical and doesn't have too many features for the software to reference (objects like car bumpers or coffee mugs), the scanner will lose its reference position, and it can be hard and frustrating to re-align the project again. The loss of reference is mitigated by placing markers on the object, which can be time-consuming and is often tricky to put the tags correctly. With the prime pack, that's no longer necessary as it allows for marker-free handheld scanning. Only available for the Pro2X Plus
