Stefania Tosa and Stefano Capoferri, both sales managers at Open Technologies, came to Dassault Systèmes offices in Vélizy, a town near Paris. Vélizy is famous for being home to several very large companies, including PSA, Thalès, Bouygues, and General Mills.

Within Dassault Systèmes, the demo was hosted at the 3DExperience Lab, a laboratory to nurture and empower disruptive projects. The 3DExperience Lab is already equipped with several 3D printers (including an Ultimaker 3+ and a Markforged Mark One) and 3D scanners. Run by CAD and design experts, the 3DExperience Lab was the perfect place to conduct this hands-on demo.

The Open Technologies Scan in a Box – FX, often called SIAB-FX, was sent to us a few days before the event by mail. Therefore, we were able to witness the full installation of the 3D scanner, including its unboxing.

Discovering the Open Technologies Scan in a Box – FX

The Open Technologies SIAB-FX comes in a very large cardboard box, full of styrofoam. This primary packaging contains two smaller cardboard boxes. The first one includes the 3D scanner and its accessories, while the second box contains the automatic turntable. Note that this turntable is optional, available separately for €890. Both secondary packages boast a nice finish and thick foam protections.

The 3D scanner’s main packaging contains the following items:

  • the 3D scanner head (made of a solid aluminum frame, a DELL video projector, and two USB 3.0 cameras)
  • a professional tripod
  • all the cables (power and connectivity) and their sheaths
  • a USB stick with IDEA 1.1 software
  • an instructions manual
  • the calibration plate with its support

We can’t help but notice that the calibration plate comes with sturdy metal support, instead of the weak acrylic version available for the standard SIAB. Given the weight of the calibration plate, this is appreciable.

The SIAB-FX is the upgraded version of the SIAB. It offers a more powerful video projector, the Dell M115HD with a contrast ratio of 10,0000:1 and a 450 lumens image brightness. The ASUS S1 that comes with the SIAB offers only a 1000:1 ratio and a 200 lumens image brightness.

The IDEA software that Open Technologies provides with the SIAB-FX unlocks some nice functionalities:

  • export atlas and triangular map texture
  • convert from mesh to range images
  • export RGB point clouds from mesh

The Automatic TurnTable (ATT) comes with its own cables (power and connectivity) as well as its own calibration plate.

Overview of the Open Technologies Scan in a Box – FX

After unboxing both packages, setting up the 3D scanner setup is quite fast. Note that users require no less than 4 USB ports to connect both cameras, the USB stick with the IDEA license, and the ATT. To connect a mouse (a must-have for all 3D-related interactions), an auto-powered USB hub or a dock station is a necessity.

The 3D scanner “head” itself has a great finish, with all the components robustly fixed on a curved, anodized aluminum bar. This feels sturdy and reliable. The little hooks to hold the USB cables in place are also a nice addition. The whole system is then fixed to the available tripod with a standard camera screw.

Testing the Open Technologies SIAB-FX

Connecting everything takes about 5 minutes; this includes fixing the 3D scanner head onto the tripod, plugging in the cables, and starting up the IDEA software. To take advantage of the full IDEA capabilities linked to this SIAB-FX version, users must go through the license manager and activate the FX modules. This includes the automatic alignment of 3D scans.

Once the SIAB-FX 3D scanner is attached to the tripod, the next step is the calibration process. This is only necessary if the default configuration doesn’t fit with the user’s particular use case. By default, the SIAB-FX is configured for the medium FoV (250 mm), great for 3D scanning medium-sized objects. Since the USB cameras focus on the object to 3D scan, their orientation defines the maximum Field Of View (FOV) of the capture.


During the hands-on demo, the test object was a plaster bas-relief. The result was quite impressive, with a lot of rich details and very good precision. In a few minutes, we obtained the dot cloud, ready for visualization. Thanks to the ATT, no additional alignment was necessary and it was possible to generate the mesh directly.

SIAB-FX testing.

Since Open Technologies lent us the SIAB-FX, we were able to conduct additional tests with different configurations. In comparison with the SIAB, we noticed various improvements (speed, reliability) on the software side of things. Furthermore, with the special FX configurations, several different and interesting features are now available.

All of the following tests were conducted using the 250 mm configuration and calibration, the best fitting mode for capturing objects measuring less than 10 cm tall on the ATT.

A colored Mario piranha plant in plastic

This object is only 5 cm tall and in full-color plastic, with a lot of intricacies and self-occluding parts. The result is quite amazing on the organic shape (the plant itself), but the flower pot which is pure geometric shapes wasn’t that great. In the end, it isn’t really an issue as such parts are easier to remodel (using the free Blender modeling tool, for example).

A white dental impression

This type of object, plaster-like, falls into the “easy to 3D scan” section. However, that means that the result must be detailed and very accurate. With the Open Technologies SIAB-FX, we obtained a very clean mesh. For this model, we tested the automatic alignment feature of the IDEA software, in FX configuration. The alignment was done almost instantly.

A plastic manatee tea infuser

This tea infuser is made from monochrome soft plastic. It is full of holes, to let in water and sink. The result is very good and has many details.

Aniwaa’s opinion

After our first impression with the standard Open Technologies SIAB, we finally got the chance to test the SIAB-FX. It is an updated version, based on the same architecture. The IDEA software in its FX configuration is also a lot more powerful, and the generated meshes are of great quality.

In the end, we strongly recommend this 3D scanner to all types of users, from wealthy enthusiasts to professionals. The performance is on par with the best products of this category. Also, the price stays affordable for SMEs.

With a manufacturer price of €4,490 (not including the ATT or a hard case), the Open Technologies SIAB-FX is not cheap. However, it is definitely a very capable product, powered by good software.

Finally, in the same price range, the SIAB-FX’s few competitors are the DAVID SLS-3 and the RangeVision Spectrum.
