The FabScan 100 is the cheapest 3D scanner we ever created. Why is it called FabScan 100? Because the parts will cost only 100 EUR!



Compared to the original FabScan, this model has some limitations:

• manual laser - the laser can be moved by hand. This saves 15 EUR for the stepper motor and 12 EUR for the stepper motor driver.
• logitech C270 webcam - this camera has a lower resolution but is still perfectly fine! The camera also can/needs to be focused manually. The viewing angle is smaller, hence the maximum size of the objects is a little smaller (It needs to fit into a cone of base 14cm and height 10cm). Compared to the original FabScan, more than 50 EUR can be saved!
• fewer screws - saves material (and money) and build time!
• KiCad Design files for a single-sided PCB can be found here: http://sebastian.setz.name/arduino/my-projekts/fabscanmod you can download KiCad for Mac OS X here
• NEW: The current PCB can be ordered here: http://www.watterott.com/de/Arduino-FabScan-Shield
