The new king of hobbyist 3D Scanners - Creality CR-Scan Otter

Creality's newest CR-Scan Otter might just be the best hobbyist 3D scanner that I've used. I put it's claims of 0.02mm accuracy and a scanning range of 10 cubic millimeters to 2 cubic meters to the test!
Thank you SainSmart for providing this scanner for review!

It would be nice to have some kind of test to check the accuracy. For example scan screws of different diameters and print them. Than test what is the smallest diameter which fits the corresponding nut.

[@Todestelzer]

That wouldn’t be accurate. You need to measure points in the point cloud. If you print it you add the printer tolerance. The printer x/y calibration, Flow calibration, pressure advance calibration and material shrinkage. The accuracy of the scanner is listed as 0.02mm. In general that means around 0.05mm accuracy in real world scanning. You can use cloud compare to measure point cloud distances for example.

The otter and raptor are really an amazing contribution to so many fields of technology. Thank you so much Creality, I commend you for your tireless efforts to help progress humanity. I had a thought/ brainstorm, could you use a clear transparent base to locate the octopus on. That way you could scan right through the underside of the base, and create data without having to flip it over? Food for thought. Please keep making informative content on how to use the Creality scanners. 🇦🇺🤜🏼🤛🏼🍀😎☮️

[@HoffmanEngineering]

I appreciate the comments! I agree, the Otter is a pretty good leap compared to similar handheld scanners of just a year or two ago. The transparent base is interesting. I'll have to see if I have anything that's transparent to infrared light. But if you can find a base like that, then I think that would work!

Came a long way from the kinect scans

[@christianlainesse4281]

are the 3D scans size accurate, or do you still have to scale them after to the original size of the thing you scanned?

[@HoffmanEngineering]

I don't know how I didn't mention it, but yes, items are scaled accurately on export.

[@stevesloan6775]

The otter creates a more dense mesh if you use markers. Markers are a must have when scanning featureless frames. That’s the best advice I can give, right there! 🇦🇺🤜🏼🤛🏼🍀😎☮️☮️☮️

[@stevesloan6775]

I think you’d freak out if you performed all of the same scans with the Creality Raptor hybrid blue laser- NIR scanner. The detail it can capture is mind blowing 🇦🇺🤜🏼🤛🏼🍀😎☮️

[@HoffmanEngineering]

I've seen really good results with the Raptor. I hope to get the opportunity to test one out and see how it compares with the Otter.

[@techr9186]

did you notice any difference/improvment from the last update?

[@HoffmanEngineering]

I only did extensive testing on the one version shown in the video. As I was finishing editing there has been a new version of Creality Scan released, but I have not been able to put that new version to the test yet.

[@henninghoefer]

How does it compare to a Revopoint Mini?

[@HoffmanEngineering]

Unfortunately I have not had the chance to try the Revopoint Mini. I'll try and get my hands on one though to test out. The Otter gives better results than the Revopoint Pop2 I last used, but that is a few years older and less expensive, so not really a fair comparison.

[@joatmon7347]

Thats a far way from using the xbox as a scanner. 😅 Cool!

[@alexmillette]

What about motocycle or car parts. I guess if it handle a full body, might be good for motocycle but not sure for a car.

[@HoffmanEngineering]

With markers, I'd expect car and motorcycle parts to work pretty well. Creality has examples of a full car body on their website. You'd need to use a laptop for it, since you'd be moving around a large area.

[@Todestelzer]

They have to improve the software. No orthogonal view what it makes deleting stuff complicated and it’s deleting the original scans after merging. No alignment function to a coordinate system. No auto alignment using markers when fusing 2 body’s. (As far I know. There is no check mark to select for Auto alignment)

[@HoffmanEngineering]

That is a good list of suggestions right there! The alignment workflow could definitely be approved, it was the only part where I struggled.
