EinScan-Pro vs DAVID SLS-3

The EinScan Pro has four modes (though two of them require an add-on), each matching a specific need. With no add-ons, the device can be used on the Handheld Rapid and HD Scan modes, which offer differing levels of accuracy and methods for stitching. With the industrial add-on pack, the EinScan-Pro can also detect color and texture, and the Automatic and Free Scan modes use a turntable for very fast, accurate scans of small objects.

The EinScan-Pro boasts professional quality similar to the Artec Eva, at a third the price. While still costly for the basic tinkerer, this scanner is of sufficient quality to appeal to more advanced users.

When multiple scans of an object are taken, to form the 3D model, there is often a step that requires the user to manually align scans to form the whole image. Some exceptions aside, the software used alongside the EinScan-Pro can do this automatically with surprising accuracy, making everything much easier.

If one purchases the Industrial Add-on Pack, which adds a turntable and a tripod for $700, objects on the turntable can be scanned with uncanny speed: one or two 2 second scans can produce a very high-quality 3D model, even on a glossy surface: example

While not necessary to the functionality of the scanner, the EinScan-Pro has a nice, sharp look that goes well in any modern office or home.

The EinScan-Pro only weighs 0.8 kg (less than 2 lbs), allowing for an easy, smooth, and comfortable scanning process, even over long periods of time.

Unlike setup and calibration, the scanning process itself is quite easy. Scanning an object from multiple positions is enough to merge the data and form a 360 degree mesh.

To operate this scanner, you’ll need the HP 3D Scan Software Pro V5 installed on your computer. The software license is bundled with the scanner itself, so you won’t need to buy it separately. The software is simple to use and intuitive, but also quite powerful. It’s divided into three main parts: setup, scanning and shape function. This means that, during the scanning stage, for example, you’ll only be presented with the functions relevant for that stage.

This 3D scanner can push its resolution to up to 0.05 mm, at 10 cm distance from the object (keep in mind that in order to be able to achieve this result you’ll have to spend hours calibrating the device). The overall result is very impressive, since a 0.05 mm resolution allows to scan objects in great detail. For example, you can theoretically scan a human hair using this scanner. This is a very powerful tool if used properly.

As the unit only has a monochrome camera, color capturing is achieved by measuring reflectivity on the surface of the scanned object.

Besides cables and hard cases, this scanner has plenty of accessories to choose from. There’s the TT-1 Automatic Turntable ( $1160.00 ), which makes 360 degree scans easier, or the DSL-1 Desk Scan Lever ( $650.00 ), which gives the scanner some extra free space for more complicated 3D scans. Another notable accessory is the SLS-3 Stereo Camera Upgrade Kit ( $1795.00 ), which improves scan quality by adding a second camera, at the cost of complicating even more the default setup, since both cameras need to be individually calibrated.

Calibrating this scanner is quite time-consuming and tricky, which can be annoying for regular use, but can be useful for teaching purposes, since the setup process itself helps understanding how structured light 3D scanning works.

This scanner's high precision 1080p camera enhances the textures of scanned objects.

This 3D scanner is designed to export purely geometric 3D formats, and is therefore capable of generating STL, OBJ and PLY files, which are more than enough for reverse engineering and geometry editing with most CAD software.
