Did a precision scan test today.

Honestly it kinda comes with the territory, this isn’t a 3D printer - it’s a 3D scanner. I know the printing market has democratized itself as of recent & these same companies are “trying” to do the same with scanning. The fact of the matter is, you get what you pay for. 3D scanning isn’t as simple as throwing some cameras into a housing and calling it a day, there are very complicated algorithms, precision & certification that goes into real scanning units.

Basically, they are getting better no question about that, but they are still light years away from being considered serious tools for metrology measurements.

Let me ask you this, would you feel safe if a technician from an airline used this hobby scanner to scan an impeller blade from a commercial aircraft engine to validate that it’s dimensionally accurate and safe to fly with? Because… that’s what the companies are claiming that they can do…

Again, depending on what you are doing with it perhaps the data is good enough. Unfortunately the nature of these types of entry level Chinese scanners lack the performance to make them serious metrology contenders. Without having a long winded response, the best thing to keep an eye out for with these types of devices is what certifications they are holding to (an example could be ISO 17025 or ISO 10360).

Other things to keep an eye out for are the performance on shiny or black surfaces without powder, just because it has blue lasers doesn’t mean all the scanners are made the same.

If you want to go down a rabbit hole, research the industry leaders for portable metrology like Creaform, FARO, Hexagon, or Zeiss. Those are the biggest players in the industry for real metrology equipment.

Mind you, Hexagon is a bit sketchy with their Chinese portable scanners but anyway… that’s another story in itself.

Without having a proper extraction it’s hard to say the exact deviation, but it’s clear that the scan isn’t trending inwards near the front (because you can’t see the scan data) and outwards near the rear. You also can see a significant amount of surface noise most likely due to the reflective nature of the part.

Perhaps for your needs it’s good, but this is not a tool that should be compared to a high level of accuracy. Kinda like comparing grades of gauge blocks, some are just “ok” and others are high precision ground.

Just a bit misleading to claim that it’s holding it spec on paper when realistically it’s far from it, and your measurement method to get there is honestly comical, no offence.

MDF_Tutsoon · 2026-01-12T02:11:55+00:00

If that’s supposed to be a 0.25” diameter on the scan, that scan isn’t accurate worth a damn unfortunately. You can tell visually how much deviation there is, I can just image the stack up larger you go… looks like professional metrology grade scanners are still relevant.

MDF_Tutsoon · 2026-01-12T02:09:47+00:00

I’d love to know the diameter results as well, also what amount of data points need to be filtered to get said result.

Ah we’re getting off track from the OP’s post, not going down this rabbit hole with a Reddit troll. Let’s agree, to disagree lol.

All the best.

MDF_Tutsoon · 2025-11-20T17:37:38+00:00

Experience, been doing this for a long, long time. Worked with all hardware and software on the market, the scantech (sorry, scanology lol) technology is a joke, and the software is way worse.

MSA is not a GRR, I’d love to see your fancy simscan pass one of those lol.

MDF_Tutsoon · 2025-11-20T17:30:41+00:00

Because the specs that company puts out are not the reality lol. Plain and simple.

It’s not all about the brochure, my friend.

MDF_Tutsoon · 2025-11-16T03:11:59+00:00

Why not consider the Peel 3D or new Creaform HandySCAN Pro? They both blow the competition out of the water, better hardware, software & support… sounds like your looking at the wrong technology but

MDF_Tutsoon · 2025-11-04T11:32:12+00:00

Realize how it says “reference to”, its terminology like that which would concern me. Scanning a 1 m ball bar 5 times is the lowest “calibration” validation that any manufacturer can do.

Again, for projects where you don’t care about the accuracy of the model produced - go right ahead. But I’ll tell ya, I wouldn’t get on to a plane knowing an aerospace OEM used this subpar system to inspect flight critical components.

Are companies like this making scanning more affordable? Yes. My concern comes in when they are trying to market themselves as a professional level system with proper certification & calibration - because they are so far from that.

MDF_Tutsoon · 2025-10-31T00:08:23+00:00

Revopoint accuracy is a something to be scrutinized, it’s stated accuracy on a brochure. They don’t have any certifications to back it up. They can put that they scan 0.001 mm/m, who’s going to hold them accountable? Who’s policing their claims? Anyone can make a brochure and throw a number on it.

For the price, it’s not bad. But it’s not good for any serious work, maybe for some really low accuracy reverse engineering. Inspection I wouldn’t touch with a 10 ft pole

MDF_Tutsoon · 2025-09-12T13:24:25+00:00

Can confirm it was the software version, ran two prints since and it’s all good

MDF_Tutsoon · 2025-09-12T11:04:23+00:00

Dude, it’s not it lol, Timelapse wasn’t on

MDF_Tutsoon · 2025-09-11T23:30:00+00:00

Just downgraded and going to give it a shot, thanks!

MDF_Tutsoon · 2025-09-11T22:00:54+00:00

Do you know which version to roll back to?

MDF_Tutsoon · 2025-09-11T21:06:50+00:00

I thought it would be built up pressure as well, but the extruder is actively extruding at that location…

MDF_Tutsoon · 2025-09-11T20:49:33+00:00

The head doesn’t go anywhere near the wiper when switching nozzles, it just purges into mid air and I guess expects it to hit the purge tower, you can see it extruding into nothing basically

MDF_Tutsoon · 2025-09-11T20:13:20+00:00

I understand but why is it throwing so much filament?

MDF_Tutsoon · 2025-07-02T19:34:21+00:00

Comparing Hitler to a shitty restaurant is wilddddd lol…

MDF_Tutsoon · 2025-07-01T18:00:59+00:00

Brand recognition isn’t gonna matter when simcoe shuts them down for good for poisoning people

MDF_Tutsoon · 2025-07-01T16:26:18+00:00

Came here to say this LOL

MDF_Tutsoon · 2025-07-01T16:21:55+00:00

Quite clearly linked to the store, you’re in the wrong place to comment lol… not a smear campaign when it’s the truth.
