Sweep laser-scanning
Sweep laser-scanning is similar to the rotative Lasers-canning procedure. It works on a flat surface instead of rotating the
object.
It has lower quality on bigger objects due to the way the camera focus works, but can give good results on medium size
objects.
This scanning method produces partial scans as the surface in contact with the bed cannot be seen by the camera and
therefore scanned.
Touch Probe Scanning
This scanning method is the most accurate, but the slowest of all methods. It’s made to scan very small objects with high
detail, like a coin or a relief.
It uses the probe embedded in the FABtotum carriage to measure the geometry of the object.
Special care should be applied as a scan that has not been correctly plannet may result in damages of the touch probe.
It works with objects that have no complex shapes and have gentle curves.
It’s also a partial scanning method as it cannot probe the side of the object wich is in contact with the hybrid bed platform.
Before starting make sure to secure the object on the hybrid bed. Using the glass side is strongly advised as the probe
cannot be get caught in the subtractive side fixtures holes.
In the dashboard, select “Scan” (eye icon), Insert the name of the new object you are scanning, select the scanning 1.
method “Probing”, then “next” to continue the scanning procedure.
Now you are setting the scanning parameters. Select the probing area coordinates. You can both select the area on

the image, or write the coordinates;
In this step you can decide the quality of the scan, choose one from:Draft: 1 Probe per square millimiters
Low: 4 Probes per square millimiters
Medium: 16 Probes per square millimiters
High: 64 Probes per square millimiters
Very high: 100 Probes per square millimiters
Ultra high: 256 Probes per square millimiters
You can also set the Z jump and Detail treshold, wich are advanced settings best explained in the FABUI.
The Z-Jump is very important as it should be set at least 1.5 times the size of the biggest height difference you
expect fromone probe point to the other.
Setting a Z-jump parameter too small will collid with the object and potentially bend th eprobe.
Click “Next” to start the scan. Your scan will start after a few moments of calibration.

The probe will start to softly touch your object and depending on the size of the area and the quality you selected
the scan will complete in minutes or hours.
After the scanning process the guided procedure will ask you to download an .asc file: it’s the point cloud coming

from your scan.
You can process it for have an .stl available for your 3d printer using different programs like Meshlab.
