Faro Edge ScanArm
The Faro Edge ScanArm is currently located in the Montgomery Machining Mall for the duration of the renovation. It is a high resolution laser scanner capable of assisting "inspection, point cloud-to-CAD comparison, rapid prototyping, reverse engineering, and 3D modeling".
Please note that although using the Faro Arm itself is easy, the real challenge of 3D scanning is in the data post processing.

- Can create digital files that represent physical objects.
- Can capture detail up to +/- 0.001"
- Can capture up to 560,000 points/sec
- Great when paired with 3D printing!
- Can reverse engineer components, and give CAD from scan. (Does not work on organic shapes.)
- WARNING: HAS A LASER. DO NOT POINT IT AT YOUR EYE, AND BE COGNIZANT OF OTHERS' LOCATIONS AND LINE OF SIGHT WHILE USING IT.
- Great for capturing objects when high accuracy is needed.
- Creates giant files. Bring file storage with a lot of space.
How to Use
The Faro Arm is a very expensive and very delicate piece of equipment. If you are unsure about ANY of the following instructions, please ask for help in using the scanner. People who just "wing it" end up breaking it.
<It can be used to reverse engineer parts into CAD, but we haven't had experience in doing that yet.>
Set Up The Scanner
- Get the Faro Arm Key (20) from the lockbox located in the Metal Shop (only during renovation). If you are not a PI, you will need one to get the key for you.
- Unlock the blue cabinet beneath the Faro Arm, and take out the black foam box with the scanner in it.
- Take the fabric cover off of the Faro Arm.
- Attach the scanner to the probe end of the arm. (If you are unsure of how to do this - ASK.)
- Turn on the computer.
Calibrate the Scanner
Before you are able to use the scanner, you need to actuate all of the joints to calibrate it. This process needs to be repeated if either the scanner or the computer turn off during usage.

Tips and Tricks
- Turn on the volume of the laptop, so you can hear the audio feedback as you're scanning the part. It helps you know when you're getting data, even when you can't see the computer screen.
- Save your file often - sometimes after every successful scan. This system crashes a lot, and it sucks to lose 20 minutes worth of work.
The computer keeps crashing.
The scanner is not picking up any point cloud data, no matter how much I scan.
The scanner is not scanning - instead, making a MRRRRRRRRR sound.
