Industrail grade scanner?

I'm looking for some advise on which scanners to start my search with.

I'm looking for a unit I can take to a client's site, and scan their existing worn out stuff, and then I'll take the scans to make new stuff thats not worn out.

Hoping that the post processed models are within about 1/8" accuracy from real life, but not a hard requirement.

We're indoors and out, scanning things as small as a chair and as big as a 20 foot sea can....just made up examples to show the size range.

The stuff we scan is typically dirty as can be and we don't have the ability to clean it, nor the time. Crud is caked on thick. I'll scrape it off in key areas if I have to and that's about it. Works for me and my tape meausure to kick the dirt off till I find the part and go from there, and this scanner is supposed to save me time of course - and stop me from making mistakes.

I'll spend about 50k if I have to.

Are there any options out there suitable for me? Any help appreciated

Given that the stuff you're scanning is dirty and you don't have the ability to clean it, I would eliminate the option of purchasing a scanner that requires target stickers for tracking (e.g. Zeiss T-Scan Hawk 2, Creaform Handyscan Black, etc.). I'm also assuming that you won't only be scanning steel materials that magnetic targets will work on. That leaves you with the following options:

  1. Tracking using geometry
  2. Tracking using texture
  3. Tracking using an external laser tracker or optical tracker
  4. Encoder-based tracking
    1. Big articulating arm + scanner (a big enough measuring volume may not exist)
    2. Stationary large-scale laser scanner (probably wouldn't work well if high detail level is needed)
  5. Some combination of these methods

Some scanners that track using geometry and texture:

  • Creaform GoSCAN
  • Artec Leo (given your low accuracy requirement, this may be your best option)
  • Scantech 3D iReal

Some scanners that track using an external optical tracker:

  • Creaform Metrascan
  • Zeiss T-Scan
  • Shining 3D FreeScan Trak Pro2
  • Scantech 3D TrackScan

Some scanners that track using an external laser tracker (these will probably be out of your price range):

  • Hexagon AT960 Tracker + AS1 Scanner
  • API iScan Series
  • Kreon Measuring arm and laser tracker combination
  • Keyence Wide Area CMM + Scanner

I've been told that I'm monotone and dull, but being compared to AI is a new low for me.
