DAVID SLS-3 3D Scanner Review

The latest DAVID SLS-3 3D Scanner operates the innovative structured light technology, which provides precise 3D scanning in a material of seconds. The 3D colour scanner is mobile and can be arranged quickly in front of the covering to be scanned. A unique click in the well-proven DAVID software starts the scan – and several seconds later the digitised 3D design shows up on your cover!

DAVID SLS-3 3D Scanner – the portable design of the scanner facilitates proper and expeditious surface scanning small and big objects, even those that are not suitable for transport. High degree, automation, and simple operation produce the user encouragement. Using the device does not require an intricate, specialised assistance.

The 3D scanning method starts one button, and several seconds later a 3D model seems on the screen and can be transshipped to standard file formats such as OBJ, STL, and PLY, and processed in other applications.The scanner is transportable and can be located quickly in front of the surface to be scanned.

An only click in the well proven DAVID software starts the scanning process and a few seconds later the digitised 3D model resembles on the screen – even the colours of the object can be optionally apprehended and reproduced in the resulting scan!

This way you can subsequently examine all surfaces of the object, and ultimately, combine them through a closed 360° model. The modular hardware setup allows a resilient adaptation to your object – any size from a coin to the couch is imaginable!


The results can be exported into universal 3D file formats (OBJ, STL, PLY) and prepared in other applications, e.g. for rapid prototyping, manoeuvres, result presentations, archaeology and cultural inheritance, works of art, computer animations, video games.

Laser Scanning: What is SL?

SL 3D scanning, contrarily known as Structured Light, is a indicates scanning objects using a projected lined pattern from a projector and reading the result using a camera. The DAVID SLS-3 3D Scanner comes with all the tools needed to perform these scans outwardly the necessity of any additional hardware or software.

SL works by pulsing a sequence of light designs at the object and building a screen from this. In association to the Starter Kit which involves painting a laser over an object’s surface, there’s a huge bound in time-saving and ease of use. That meaning published, setup time initially, for those new to 3D scanning, can be somewhat slow. But once you polish the process you would be available to scan an object within 5 to 10mins.

The hardware incorporated to do the SL scanning is extraordinary. An Acer K11 projector, high-quality camera, Hahnel great adjustable tripod, two calibration studios and the DAVID software on a USB tool.


You can do polygon decimation in Blender or other 3D software as the results are too detailed to use in SketchUp and basic 3D software.

The DAVID SLS-3 3D Scanner

The DAVID SLS-3 3D Scanner, as discussed takes some time to setup, but you are supplemented through the process with a supplied User Guide. The hardware assembly is outspoken, and the only real head scratchy comes when you have to do a bit of mechanical measuring of objects and measures between projectors, cameras, and objects.

Once you are ready, the DAVID scanning software resembles after most everything. Projector and camera calibration fit with centre rings and opening perspectives, but it takes continued to type that decision.

While all is turned in you can start the scanning method. It isn’t sufficient to do other than click scan and twist your object on completion. For a full 360 degrees scan, I found anything between 8 to 12 rotations gave the best results.

To take your series of scans and consolidate them into one mesh the DAVID software has a system called ‘Fusion’ which will automatically adjust and improve any holes in the scanned screen and export the decision to either .obj, ply or STL. Ideal if you plan to go the 3D print management.

You can also prefer to export each scan independently to do additional work in applications of your selection. A different element to ‘Fusion’ is that it can more apprehend arrangements and implement these to the scanned meshes.

I did play with this moderately on distinct objects with mixed results. It is not flawed, but when administering with lighting and reflections, it can get intermittent with noticeable changes in textures from scan to scan.

Outstanding value for money

3D scanners cost many thousand of the euro? Not anymore! David-SLS-2 is a full 3D scanner that is capable of digitising tiny to large objects in stunning detail – and at an unbeatable price!

Highly flexible design


The scanner can easily be adapted to different object sizes and levels of precision. In combination with a laptop, this robust and light hardware forms a highly mobile scanning platform.

The structured light technique does not require moving mechanical components, making the scanner low-cost and wear-free.

Very easy to use


After the scanner has held calibrated for the suitable object size using the enclosed calibration panels, each scan can be inaugurated with only a single mouse click. The software immediately generates the 3D data and displays it in the 3D viewer.

This releases it easy to scan and save different views of the object in succession – 360°, top and bottom views and occluded areas.

Post-editing made easy

Only a few clicks are required to retouch, align and fuse the scan together to create a watertight 360° model that can then be saved in widely used CAD formats (OBJ, STL, PLY) and imported into most 3D programs.

The 3D data is to scale in mm and is thus suitable for making measurements and comparisons as well as for 3D printing or CNC milling.
