It delivers excellent scanning performance when compared to other scanners in the same price range, known for delivering professional scans. So, let’s have an in-depth look at this outstanding 3D scanner to know whether the machine is worth the money it charges.


Compact S1 uses structured light technology for capturing high-resolution 3D scans from real-world objects. The scanner is known for its simplicity in operation. It lets users get right to scanning in minimal time. All its components, as well as software, are designed keeping in mind the user-friendly attribute.

The machine’s scan data quality is up to the mark. It is also equipped with a live scan feature for situations in which users may want to manually scan a part or functional prototype.

Above all, the average scan time of S1 is just over a second allowing the operator to capture multiple scans of the object quickly and consistently. Below mentioned are some of the most exciting features of the scanner which separates it from a bunch of other scanners falling under the same price range.

Straightforward setup

Once delivered to your place, all you got to do is:

  1. Place it in a dedicated space.
  2. Connect Polya S1 3D scanner with power supply.
  3. Install the included FlexScan 3D scanner software on your computer.

That’s it. Your system is now ready to scan objects of varying geometries. The makers of the scanner have paid special attention to keep the pre-scanning phase very fewer efforts demanding. So that users can dedicatedly scan their parts and come up with a clean one that can easily lead to the manufacturing of accurate models.

Fast scanning

Polyga has equipped compact S1 with a system that is capable of scanning with millions of 3D measurement points under one second. Due to such a characteristic, operators can easily scan more than one part in a minute. This feature makes the scanner eligible for the on-demand manufacturing industry.

Also to mention, how the scanner maintains its level of accuracy even while delivering speedy scans. S1 has a scan accuracy of 35 microns even while processing parts with intricate geometries and small sizes. So, with S1 in your project, you are assured to have quantity with quality on time.

Intuitive in use

Compact S1 is one among those 3D scanners that produce top-quality 3D scans from real-world within a click of a button. Users do not need to calibrate or recalibrate the system for perfection. Also, it comes with very easy-to-use software that understands your needs based on the tools that you’ve selected.

Operators can have complete control over the scanner from their devices. Most of the functions are automatic. So, they save time and energy for users, thereby boosting productivity. FlexScan3D captures and post-processes scans in various file formats so that users can use the scanner with almost every 3D printer.

Varied areas of application

The manufacturer claims how S1 can be used in five different industries: Arts, manufacturing, archaeology, research, and designing.

The scanner can process parts and functional prototypes for 3D modeling, archiving, computer and vision, basic quality inspection, landmark studies, 3D printing, measurement, comparison analysis, reverse engineering, as well as product development. This gives users the flexibility of choosing objects from a varied range of industries.

Simplistic design

S1 has a sleek and slim build. It’s not only easy to change the position of this scanner from one place to the other, but also to take it along with you during travel. The machine can be put in your suitcase or travel case.

Easy to use software

FlexScan 3D scanning software includes all the basic needs of the user. It is based on modern algorithms that easily convert acquired scanned data into a digital 3D model. Moreover, the application includes fundamental quality inspection measurement tools for deviation analysis which is very rare.

The software allows the creation of digital models ready for use in applications such as 3D visualization, metrology, reverse engineering, and a lot more. It saves time by processing 3D scanner data at the capturing stage with:

  • Built-in data editing
  • Alignment
  • Merging capabilities

The final output can be exported in file formats such as PLY, OBJ, STL, ASC, and FBX depending on your needs.

Compact S1 hosts a unique camera of 2* 2-megapixel mono or color, as per your requirement embedded on its body. The camera does fantastic work of capturing images in high definition. Such an apprehension leads to scans of parts or functional prototypes with an accuracy of 35 microns.

All of that at a scan speed of 150 milliseconds with 2 million average points on a 27 cm * 16 cm * 6 cm device. The point-to-point distance on S1 is 0.07 mm, whereas its standoff is 170 mm. S1 exports a scan file in the following formats: PLY, STL, OBJ, and ASC using FlexScan 3D software.


To know the exact price of S1 one must request a quote from Polyga.


Compact S1 is a plug-and-play 3D scanner that allows users to get to the scanning phase of an object within no time at all. Thanks to the scanner manufacturer, there is no need of calibrating the scanner. All that one needs to do is keep it in a dedicated space, give it the required power supply, and install the software.

Scan Type

The machine is based on laser triangulation technology wherein a combination of camera and laser beams scans the objects by projecting millions of points on them.

S1 does not feature a turntable; otherwise, other desktop 3D printers of entry grade do feature a turntable where an object can be kept and rotated to capture each and every perspective of it.

Scan Quality
