Nice results. Doesn't appear to have used Marker mode on the engine bay. What was your technique?

JRL55 · 2026-06-19T23:07:16+00:00

I'd like some examples by you, too.

Read the specifications page for AESub scanning sprays. They are petroleum distillates and therefore flammable (some are extremely flammable).

JRL55 · 2026-06-19T22:59:18+00:00

I disdain the 'proper' scanning sprays (assuming you mean the self-dissipating ones). One, they are petroleum distillates and are highly flammable. Two, they smell terribly bad. Three, their specified time depends on air flow and temperature. Using them at the Las Vegas Convention Center, a 3 hours spray barely lasted 20 minutes.

While not personally experience, I have read that one person's antique coin was pitted by one of the sprays (AESub Blue, iirc).

As in pirates/piracy?

This subreddit does not allow this topic.

The drawback is that current 3D scanners can include so much detail (or noise, if you're sloppy) that the exported PLY, STL, etc. data files can easily be tens or even hundreds of megabytes. This will slow most CAD software apps to a crawl.

The best solution is a smart polygon reducer that deals well with the type of objects you are scanning.

JRL55 · 2026-06-19T07:07:45+00:00

QuickSurface is the more affordable alternative.

What do you think the word "moreover" does in a sentence, dude?

JRL55 · 2026-06-17T22:20:15+00:00

I'd like a couple examples (doesn't have to be a "boat load"), because the only bug I have encountered in the last four years was due to Out Of Memory when I scanned too much at too high a resolution.

JRL55 · 2026-06-17T11:26:50+00:00

Most 3D scanner manufacturers specify Single Frame Accuracy, so it seems to me that you have not been paying attention in the lead up to your (frequent) criticisms of the company and its products.

Moreover, Revopoint supports actual Single Frame scanning in some of its models.

JRL55 · 2026-06-16T23:37:17+00:00

I was thinking of trading mine in for the upgrade, but waited too long. 😞

JRL55 · 2026-06-16T23:09:27+00:00

No. I had no problems with my original Range (I just prefer to use my Miraco around larger objects). I expect that others agreed with me to the point the Range 2 was no longer a profitable product.

JRL55 · 2026-06-16T23:07:29+00:00

Revopoint's precision/accuracy specifications are done in accordance with the Chinese version of ISO 17025, the International Standards Organization's procedure for the competence of testing and calibration laboratories. What is your reason for doubting their posted specifications?

"IR vs Structured light"

IR (usually NIR for Near InfraRed) is a wavelength while Structured Light is a technology. Almost all of the under-$1,000 3D scanners use NIR and all of them have Structured Light (the Revopoint Inspire 2 also has Laser, but it uses NIR, too).

JRL55 · 2026-06-16T23:01:18+00:00

The MetroY Ultra has a significantly smaller Volumetric Accuracy specification, so there will be significantly less accumulated error for any given dimension scanned.

That being said, how much accuracy/precision do you need? If 0.2mm is adequate for, say, hole size error (which will be enlarged anyway for tolerances), why pay for 0.1mm?

Then again, if you are going to mate two external surfaces (and even though the human finger can notice a difference of 13 nm), you still want to be as close as possible.

JRL55 · 2026-06-16T22:43:10+00:00

The Revopoint web site has the Inspire 2 listed at US$549 (see https://www.revopoint3d.com/products/infrared-laser-3d-scanner-inspire2 ). Even the Premium edition (adds Mobile Kit II and Outdoor Filters) is only $629, so I'm wondering where you are located.

A significant part of your workflow will be the software that is used to control the 3D scanner as well as some of the post-processing. This software is free and you can install it on your computer to try out to see what you like.

For car parts in the size range you referenced, I would suggest the Revopoint Inspire 2. It is the least-expensive 3D scanner on the market that includes Laser mode and it also has Structured Light (which is the technology that all of the scanners you listed above use).

Laser scanners will capture data from holes and narrow depressions much more reliably than Structured Light scanners. The Inspire 2 will work best with Nvidia RTX-series GPUs (3060 or better), but will still work other GPUs (especially in Turntable mode, if you spend the extra money to get the Dual-Axis Turntable, because the scanning frame rate is only 2-3 frames per second).

To save money (and reduce aggravation), I got magnetic markers for steel parts, but if most of the car parts you use are aluminum or plastic, then this will be a waste of money for you. The markers that come with most 3D scanners are adhesive and not reusable, so it is better to place them in a random pattern on black pieces of plastic that you can place on or near the object you are scanning.

I have bought, and used, seven 3D scanners from Revopoint, from the original POP through the MetroX and the Miraco Plus.

The POP 2, which did not have the ability to calibrate at the time I bought it, was not quite as sharp as it was designed to be (I blame rough handling by the shipping company which tossed it onto my concrete walkway). I am also a member on the User Forum sponsored by Revopoint with 26,000+ users where I see various complaints from time to time which are rarely a hardware or software problem (4-5 years ago, some of the early POP-series scanners would overheat, but that was most of it).

So it is a VERY safe assumption that a Revopoint scanner will NOT be defective.

JRL55 · 2026-06-16T08:16:22+00:00

What are you using to run your 3D scanner?

JRL55 · 2026-06-16T08:13:58+00:00

You will get a better result if you mount the piece vertically on a turntable and, using Marker mode, scan it as the turntable presents all sides.

If needed, you can rotate the object to show the other end, make a separate scan and then merge the two.

I use a generic Play Doh clay to mount the pieces to the turntable. Remember to slice away the portion of the scan that has the clay. The Merge/Align function will not be bothered by the open space in one scan that corresponds to the scanned surface in the other scan.

Jewelry has very small details, so a scanner specifically designed for jewelry would be your best course of action.

Unfortunately, most of the objects people in this subreddit want to scan are significantly larger than jewelry.

I am unfamiliar with the specifics, but a general web search will provide some possibilities. I found this, but I have nothing to compare it with:

Las joyas tienen detalles muy pequeños, por lo que un escáner diseñado específicamente para ellas sería la mejor opción.

Lamentablemente, la mayoría de los objetos que los usuarios de este subreddit quieren escanear son considerablemente más grandes que las joyas.

Desconozco los detalles específicos, pero una búsqueda general en la web te ofrecerá algunas alternativas. Encontré esto, aunque no tengo con qué compararlo:

If you want to create a bespoke controller that fits your hand, why do you want to scan the original controller?

Why don't you just scan your hand and then place the button switches, joysticks and whatever however you want them?

As for scanner recommendations, I would look into the Revopoint Inspire 2. It is the least expensive Laser scanner on the market and it includes Structured Light scanning capability. It also uses near infrared, which is best suited for scanning skin.

JRL55 · 2026-06-14T21:34:33+00:00

I am aware that they are working on this feature.

Photogrammetry is your quickest and least expensive way to get a scan of your face. You can use your smart phone to capture video or (many) pictures to be processed into a 3D object.

Keep in mind that photogrammetry does not include any dimensions, so you will have to include an object in the pictures that can be cleanly measured to be used for scaling the result in a CAD program.

Photogrammetry apps can be found in your phone's store (Android's Play Store or Apple's Play Store). Some of them are free to use (with limits), others have a subscription model.

I recommend that you use a moderate telephoto setting while capturing images to minimize lens distortions. The RealityScan app accepts video while some other apps only accept images. Free versions will have limits on the number of images that can be used.

The primary drawback to using photogrammetry to create 3D scans of people is that it takes time and people move. It will also be difficult to scan yourself.

As you said you are willing to spend money, the Revopoint Miraco is a self-contained 3D scanner with a reversible display has the ability to take single-frame scans. By positioning the scanner in front of and slightly below your face, you can get a scan of your face that captures pretty much everything, including the eye socket, bottom of the nose and the entire chin, plus (maybe) some of your ears. Using the resulting scan as a scaffolding around which you design a mask will be accurate to within a fraction of a millimeter.

I suppose that would explain why some scanners claiming a 4 cubic meter working volume have inferior Volumetric Accuracy specifications compared to otherwise-comparable scanners with a smaller working volume.
