  • HD textures of extremely good quality
  • Hairlike detailing possible
  • The cost might be a huge issue for users who are not looking to invest much

iReal 2S is a handheld 3D scanner produced by ScanTech – a manufacturer based in China. The machine uses double scattering 3D scanning technology using a blue LED and infrared light. It pays special attention to increasing texture reproduction, scans accuracy, and detail capturing.

The scanner features a wide scan area enabling users to process objects of large geometries. Also, the machine has a faster scanning speed than most of its competitors. Moreover, the machine’s intelligent alignment system ensures that there isn’t any compromise on its scan accuracy.

But is the scanner worth buying or not, we can only say after looking at it in-depth. So, let’s get started.


iReal 2S comes with a fully automatic post-processing algorithm that makes the after-scanning phase extremely easy for users. An HD color reproduction guarantees that the end result meets the texture acquisition requirement of customers.

Being a 3D body scanner, the machine delivers top-notch performance while scanning different parts of the body, especially eyes and hairs.

Below mentioned and explained are some of the most amazing features of iReal 2S.

Specialized body scanning

Although based on infrared light technology, iReal 2S is not only safe but also comfortable for the body as well as face scanning. It captures 3D data of human eyes without any lack of precision. Also, extremely difficult hair scanning becomes possible using the scanner.

This makes the scanner extremely useful in the field of healthcare specifically to surgeons, healthcare professionals, and medical equipment manufacturers.

Apart from that, the scanner is used in education and research and other fields where it is important to have a measurement of body parts for customizing the experience of a user.

Super HD Texture capturing

iReal 2S is designed to give importance to texture capturing which is one of the most important aspects that most scanners miss out upon.

The machine can profoundly fulfill the visual experience of texture capturing in various fields. Due to this, the end result will always be capable of generating dimensionally accurate models.

The scanner’s precision finds it an application in the fields of energy, VR showcase, antique and sculptures manufacturing, as well as entertainment.

Scanning without markers

This feature separates iReal 2S from other scanners that are provided with markers to help users scanning difficult geometries.

The device can scan all kinds of objects, be it one with continuous or irregular textures or geometric features. All of them can be processed without any markers base on texture and geometric alignment.

A blend of alignment modes

iReal 2S combines texture, geometric, and markers alignments to make a perfect scan of continuous or intricate irregular geometries. Such a process ensures users that the end result does not miss out upon any kind of detailing they are particularly in search of.

Accurate scanning

The scanner can process objects with a point accuracy of 100 microns in blue light and 150 microns in infrared light.

When scanning with the former, the machine hosts a point distance of 0.2 to 3 mm, whereas in the latter it increases from 0.5 to 3 mm. iReal 2S can capture even tiny hairs and fibers with equivalent accuracy.

It produces 24-bit color images with an alignment accuracy of 0.2 mm per meter in blue mode, and 0.25 mm per meter in infrared mode. By fusing the texture and geometric alignments, the machine is capable of scanning irregular textures without using markers.

iReal 2S processes parts or functional prototypes using Blue, and infrared light. The former is visible, whereas the latter is not. Also, the former is an LED light that is eye-safe, whereas the latter is Class 1 eye-safe.

Both of these light waves support colored scanning and reproduce an outcome in 24 bits.

The typical measurement rate of the scanner is 1,500,000 measurements per second which is extremely impressive considering its competitors.

The point distance ranges from 0.2 to 3 mm while dealing with the Blue light, it changes to 0.5 to 3 mm while scanning with infrared light.

A point accuracy in a single frame is up to 0.1 mm per meter while processing with the blue light, and up to 0.25 mm per meter when scanning with infrared light.

The scanner’s best scanning distance ranges between 350 mm to 650 mm. Its effective working range is from 250 mm to 1000 mm.

Users can scan an object with an area lesser than 520 mm * 510 mm. iReal 2S is able to deliver end-results in file formats such as OBJ, STL, PLY, ASC, and SK.


iReal 2S is available for $9980.

First Impression

ScanTech iReal 2S

The scanner comes in a box along with:

  • HD cameras.
  • USB cable.
  • User’s manual.

Its body is white in color which gives iReal 2S a professional look. The machine weighs 2 kilograms only and hence doesn’t require too much effort while transferring from one place to the other.


There is no need to assemble the scanner. As soon as it is delivered to your place, you give it the needed power supply to start scanning.

Although experts recommend using a user manual, it’s only for those who do not have any past experience with 3D scanning. Doing so would help you gain an idea about the components present inside the machine.

Scan Type

The scanner is based on double scattering 3D scanning technology in which two light sources typically project blue and infrared light on the object.

Based on the reflection given by the objects, the sensors present in the scanner create dots which are then connected to form a pattern that becomes a basis of the end-scan.

Scan Quality

iReal 2S is primarily a body scanner. And it does a perfect job of scanning parts as small in size as human hair.

When it comes to scanning intricate geometries, the machine does it without making use of any kind of markers which is something not many scanners are capable of doing. Also, the mixed alignment modes make it easier for the user to combine the data collected either for continuous or irregular textures.


ScanViewer 3D software is a free yet powerful 3D software that includes inspection as well as scanning functions like Distance, GD&T, and color map. You can get to use the demo version of the program from the scanner manufacturer’s website.
