Both scanners were tested with high quality steel drill bits in 6, 5, 4, 3 and 2 mm diameter. Here's what I found.
Otter:
- It can scan object up to 4 mm in diameter as it can't complete 3.0mm drill bits.
- In marker mode, it will track better if the object is in lighter color (less contrast with markers)
- Otter accuracy is around 250 um (0.25 mm) when scanning small object.
Raptor:
- It can scan and complete the object with the size of 2.0mm in diameter.
- The accuracy is high. Only 2 - 40 um (0.002 - 0.040 mm)
- It can practically replace 2 digits vernier caliper.
Here's the link to my markers collection.

Nice review! Thanks :) waiting for more videos with Raptor

@lipinskirl 3 месяца назад

Good video, could do without the music. At least equalize the volume. Other than that the info was great!

@Payo-TensileCreator 3 месяца назад

Thanks for advice. Still learning the video editing, I'm new to this.

Drill bits are generally a bit undersize. Measure those bits with a caliper or micrometer if you have it. My guess is the Raptor is probably much closer than you think to the real dimensions. Disappointing to see the Otter so far off :(

@bruceschena4735 3 месяца назад

the cutting tip on twist drill is generally very close to the nominal dimension. however, the drill blanks are often TAPERED slightly to avoid jamming in deep holes. This means that the portion that is held by the drill chuck is usually undersized from nominal.

@Karol-ip6vx 4 месяца назад

Very interesting test. I don't know, maybe Inventor can approximate points with cylinder? Then measurement will be easier. Another option is to use thin layer of points (whitch should be a circle) and then approximate with circle and measure diameter.

@Payo-TensileCreator 4 месяца назад

Inventor can only snap into plane, points and making thin section of point cloud. There's some software out there that can detect cylinder and holes. But it's hard to tell how software judgement on uneven surface or missing scan data. For fine and critical measurement, manual tracing gives most accurate result. Finding diameter with 3 points circle is do able but the drill bits have to be aligned perfectly perpendicular to floor plane and parallel to each other, which is not in this case.

this type off tests helps a lot to choose. Thanks for the good work!! Can i ask you a question about my laptop?

GREAT VIDEO !!!

@enricoenry9502 3 месяца назад

Thanks for the video. What I see is that Otter seems to read the measure with a constant divverence of about 0,2mm (200microns). If so I can't talk of precision but unaccurate measure. I think that the precision is almost the same but the absolute values of the Otter seems that need only to be calibrate. What about my diagnosys ?

@Payo-TensileCreator 3 месяца назад

Infrared scanner read different value in different surface condition, bright, dark, reflection. Laser seem have lesser effect from surface condition. I don't think calibration will give better accuracy for Otter, because it's calibrated in pure black dots on white bord.

Cool 👍 thanks for doing the video! Very helpful. Next video slots and holes… haha how small is too small for the raptor…. This is something the handyscan and others find tricky. EMS3D did a test on their channel “3D Scanning Holes - An In-Depth Review” …. (Nice pun they made)….

@Payo-TensileCreator 4 месяца назад

Object with known diameter and various hole sizes, what would that be?

@75keg75 4 месяца назад

@@Payo-TensileCreator I guess. I think that video the EMS3D did they had various holes and some slots they had milled into a steel plate and they tested to see how accurate the scanner was. You could use the orange drill base/ stand to see how accurate it is for holes, how deep it sees into the hole and circularity. The slots i guess you could 3d print something?

@Tony-iz6tf 4 месяца назад

Those drills are not 5.00. On a good drill, you would have an axial h8 tolerance, which for this diameter bit is +0/-18 μm. The bits used in this video are probably not h8 tolerance.

@Payo-TensileCreator 4 месяца назад

Yes, you're right. It's just the only object that I have with known dimension and smooth grinding surface. Testing with brand new milling bits would be better but I don't have any of those.

@cory4692 3 месяца назад

@@Payo-TensileCreator I mean.... scanning a pin gauge would be better as they are actually known values with a reported tolerance. A few Deltronic XX class pins would give the best test against an artifact and cheaper than carbide for milling.

@radiatorgrillestore 3 месяца назад

Thank you. Great videos! What would be a good value computer now to run the Otter. I suspect some of my issues with scanning car parts with the Otter are processor and GPU related. Do you find that processor and GPU can help with scanning accuracy and not losing scan?

@Payo-TensileCreator 3 месяца назад

CPU and GPU will both run when scanning. My laptop RTX 4070 runs at 100% load, and CPU 8945HS runs at 50-60%. The hardware won't impede the accuracy, but stutter will affect tracking performance. It'll track and back track much faster with higher FPS and you'll complete the scan sooner.

@radiatorgrillestore 3 месяца назад

I am having issues with tracking trying to scan a car bumper. Any suggestions? My hardware is laptop plugged into AC, AMD Ryzen 7 4700, Radeon graphics, 2MHz.

@Payo-TensileCreator 3 месяца назад

Did you use marker? Marker is more accurate than geometry tracking, especially a long object. Sometime 10mm drifting can't be detected visually. I always use marker mode for works that require accuracy.

Would you recommend creality scanner over revopoint?

@Payo-TensileCreator 3 месяца назад

None of Revopoint scanner can do this. They can't see black and metallic. You need to spray the surface and they also track with only 12 FPS vs 30 FPS in Otter and 50 FPS in Raptor. This speed separates toys from tools.

Does Creality Scan software works with AMD gpu's ?

@Payo-TensileCreator 4 месяца назад

I have tried it with AMD integrated graphics 780M. It does work with some hiccup, but I can complete the scan just fine. I haven't tried with AMD desktop GPU yet.

in fact, otter is more impressive here, considering that in fact in one mode it can scan both cars and drills)

@Payo-TensileCreator 3 месяца назад

Yes, if you can afford only one scanner. Otter is a very reasonable choice.

This is extremely helpful video! Thank you for your work! Finally we have on the market accurate enough scanner suitable for fabrication purposes for half the price of metrology grade one! Raptor is real banger, definately gonna buy one. Cheaper options like Einstar and other Creality scanners are realistically good enough only for visual applications like videogames
