  I am a manufacturing engineer in sheet metal. Looking for a solution to scan finished parts and compare to CAD or previous scanned part to find missing hardware and other features out of spec is there a way to do this with your system

  Hi Travis, surprisingly enough, this is a feature that we're releasing either this week or next!

  It's also available via the API. 

  The feature does essentially exactly what you're describing, by comparing two meshes or a point cloud and a mesh against each other and then coloring the mesh based off of distances between the two. This is useful. If you have an original CAD spec that you'd like to compare against a scanned real world model. Adjustments for color can be made in the UI or API. We also allowed for exporting the heat mapped mesh. 

   

  I'll have more information about this in the next few days. Please make sure you're signed up to our newsletter to receive an update about this.

  I'll also try to remember to post on the forum as well.

  Well this is awesome. I think we will be purchasing a unit soon for T&E. Thanks!

  In looking at some reviews and understanding better how the scanner is measuring. Has this been used in a large industrial/manufacturing environment? I wanted to use our large pallet wrapper as my turn table which is out in the open with non uniform backgrounds and imperfect lighting. It also does not step in sequence like your small rotational table. Would very slowly rotating the part work this way or do I need to make a  turn table strong enough for large parts that operates off code from the scanner as yours does?

  Hi Travis - Drew asking me to pass on some answers to your questions.
  
  "Has this been used in a large industrial/manufacturing environment?"  - Not specifically, but similar setups yes.

  "I wanted to use our large pallet wrapper as my turn table which is out in the open with non uniform backgrounds and imperfect lighting". - I know the types. I used to work in a plastics manufacturing plant in shipping and receiving. I think the issue here is the distance to the object. The FOV on the cameras is 38 degrees horizontal, and we have a maximum of 1 meter scanning distance. It's really meant for small to medium objects.  However a robot arm does help make quick work of large objects because positioning is be done by the arm and accurate, and then fed to the scanner or corrected in the files.

  "It also does not step in sequence like your small rotational table. Would very slowly rotating the part work" - No this will not work. You need the scanner and the object to stay stationary while capturing.

  "do I need to make a turn table strong enough for large parts that operates off code from the scanner as yours does?" - Turntables for parts this size wont be practical and likely miss parts of the object (due to the HFOV). Other customers have either used a tripod for occasional metrology tasks, or adopted a robot arm to move the scanner around instead of a turntable. What are you scanning?

  I might suggest a Freescan-trio from Shining 3D. Or perhaps a Metro X from Revopoint, although depending on what accuracy you need, this might not be the right choice.
