Creality Scan Otter - Scanning Tips #1

- Here's some tips for scanning flat and featureless object in geometry mode. Otter small/medium depth camera track very well in this mode, unlike when it's in marker mode. Adding feature to the scene will make this scanner be able to scan almost anything. (Faster than Raptor)

You are a real master of 3d scanning! It's such a fantastic idea to construct such objects to add additional surface for better alignment. Keep on your excellent videos!
Thank you! Cheers!
Love all these videos mate. What you're doing for the community is great!!
What's your opinion on this Scanner versus an Einstar 3D?
I never own an Einstar but what I've seen from other videos when they scan similar object, I think Otter gives much more detail in both small and large mode.
What a legend! Thanks
and may I say to these 'bloggers' advertising the scanners: 'fk you for pretending to make it look so easy'
Hi,
So what joystick do you use to work on Blender?
By the way, thanks for your videos, because I'm having a hell of a time testing the Otter I was sent, and small parts are extremely difficult to scan. I practise every day, but the targets escape or don't appear at all. For example, I tested a poker chip - it's not as small as all that - that I'd placed high up on a bottle. Well, the scanner could see the bottle, but not the chip, which was red and white and matt. I don't understand this thing. As for the coins, the only one I managed to scan, the result was totally useless, no precision at all, despite what Créality says. I really don't know whether I'm doing something wrong or whether the device really isn't up to the job.
What surprises me the most is that even when you scan an absolutely smooth surface, you still end up with a weird texture, like on your spanner, whereas the Raptor does this much less. Is there a solution to correct this without necessarily using Blender?
In any case, thanks for your answers if you have time to reply.
I made a rematch wrench test by spraying with developer spray. The result is much better but no match for Raptor.
Which mode were you scanning? Marker or Geometry? I haven't found that Otter won't see some color/surface condition. But Raptor's NIR can't see matt black (tested many times) I also found that if the object has high contrast color (Metal and black, white and black). The Otter won't scan as well as lower contrast object. The only way to resolve this is by using spray.
Joy stick.. do you mean the Space mouse that I use for orbiting the 3d model? It's 3DsConnexion space mouse, widely use in CAD user over 15 yrs.
@@Payo-TensileCreator Hi,
What joystick do you use to work on Blender?
For the scan, I was in marker mode. I just printed all the little pyramids that you put on your video, it looks better por scan an air pod, as Créality asked me, it works a little better anyway, I have to try again coins. But I didn’t get the details, which didn’t appear on the part I scanned.
Ok for the spray, but it's really expansive !
@@Payo-TensileCreator Ah OK ! cool ! Love it for the functions ! I had already seen some, but I had never taken the time to look closely!
Great video.
I assume you are using geometry feature mode because it gives you a higher resolution mesh when scanning. As apposed to using marker mode that gave you a lower resolution mesh?
Going by your previous videos.
Am I correct in saying this object is a perfect candidate for the Raptors laser scanning?
Also when performing the subtractive Boolean in blender, you could cut off the majority (80%) of the objects mesh, before performing the subtractive Boolean. That way the polygon count would be vastly lower prior to the Boolean calculation.
As always your videos a very interesting and inspirational.
Otter small object in marker mode scanning experience is not so good. It won't track as smooth as in geometry mode, just do able but not designed for.
These videos are really wonderful thanks for sharing!
I'm having a very hard time choosing between the otter and raptor. I intend to scan mostly objects of similar size to what you did in this video.
Power tools (drills, impact guns, IR Temp gun, etc) and hand tools (digital calipers, micrometer, tape measures, hammers, screwdrivers, etc.).
My goal is to organize my workshop by 3d printing custom gridfinity holders for all of my smaller tools after scanning them exactly as @PhilVandelay on youtube did in his most recent video "How to 3D Print Custom Tool Organizers for ANYTHING!"
In your opinion which one of these scanners would be the easiest to use with this in mind?
I don’t believe I need absolute accuracy as the holders will have a small amount of extra gap to account for error and to make the tools easier to extract. Thanks for any input!
If you can have one, Otter is a good choice, it's cheaper and can be used to scan larger object without markers. But for me, I prefer to use Raptor for object that's less than 70cm in size, it's faster and easier to scan with.
@@Payo-TensileCreator Thank you! Ease of use is my #1 priority. I have many things to scan (hundreds of things!) and all of them are under 70cm in size. Would you say the Raptor will be the faster and easier scanner for these items for a beginner? Cost is not a major factor, only ease of use.
@@blaine3384 Raptor is easier to scan in blue laser mode. You won't have any issue with tracking. It just works.
Hi Payo, I'm having trouble with getting a scan into a usable form in Fusion 360. The scan is 2 bodies that I need to capture their spatial relationship so I can design around them. The scan also only has the faces that I need and not the back sides. When I insert the stl file into Fusion I cannot repair it in the mesh panel because Fusion 360 has too much to process and it takes forever and never completes. Also if I try in Creality Scan to fix holes, it takes away contours and detail that I need. Do I need to use another program to clean it up or am I doing something wrong in Fusion?
If I would do additional work from a scan file in CAD (I mainly use Inventor) I'd export it as point cloud, never in mesh. It's much easier to work with. But AutoDesk required that you need to convert point cloud file into their proprietary file name RCP which has to be done in ReCap (additional cost) Not much you can do with polygonal mesh in CAD, it'll burn out your hardware resource and it's a different kind of 3D model. Polygonal mesh is good for 3DsMax, Blender, Maya or Zbrush but not for CAD.
Hey Payo my Otter master. Currently I have some parts that keep to eat my RAM. The part is roughly 300x200x100mm and I scan it in small mode with trackers. I even upgraded to 64GB and it still runs out of RAM. Do you have similar experience when creating the dense cloud? How much RAM has your beefy 4090 machine?
Btw. When building dense cloud I always use maximum resolution (0.05) because the parts I do are for reverse engineering (metrology). Have you made any experiences in regards to dimension deviation when choosing a lower resolution (example: 0.2 instead of 0.05) ?
0.05 mm resolution is marketing gimmick. You'll get the same or lower accuracy when using resolution lower than 0.1mm. You don't need dense point cloud for doing reverse engineering, but the accurate one. Usually, I'll keep my point cloud under 5 million for medium size part. Otter small/medium object exhibits strange behavior in marker mode, but the software never reaches 16 GB of RAM usage in my experience. The VRAM usage is also very low, under 2 GB. I think Otter small depth camera is not especially designed to be used with marker.
how detailed can those scans be?
Hi! I have the otter but i am having trouble using it with an active usb3 5 meter extension cable, in the creality scan software it shows as having a usb2 connection but its getting enough power over just that cable, fps while scanning is around 11-12 which is what i get with other usb2 cables, if i plug the scanner in with its own cable directly into the computer i get 30 fps.Have you tried using extension cables?Have you had any success? The 2 meter cable with the otter is not enough i feel for confortable scanning with my desktop, any thoughts?
I've the same problem, some cable work, some don't. The one that works is 40 GB/s cable. Anything that doesn't has 40 GB/s sign on it won't work.
@@Payo-TensileCreator Have you by any chance tried ALOGIC 5m USB 3.0 Active Extension Cable or one that looks exactly like it? That one seems to work with vr headsets when others dont maybe it would work with the scanner.
@@George-ym8jk I really don't know that cable maker. All my UGREEN USB C cable don't work with Otter. But the unbranded one with 40 Gb/s sign works but it's 3m cable not 5m
