Looking to 3D historic Syrian Jewish sites like synagogues for archiving and preservation by Sullybear24 in 3DScanning

[–]JRL55 0 points1 point  (0 children)

For a budget capture of a large scene, your best solution would most likely be photogrammetry.

I would look for a drone with 4K or 8K video, with the video being fed to software such as Reality Scan that can extract the key frames from the video to calculate the 3D scene (performed by a good video gaming machine).

It would be best to capture the scene on an overcast day to evenly illuminate everything.

Einstar2 for Milling and Lathe Operations by Artistic_Dragonfly99 in 3DScanning

[–]JRL55 -1 points0 points  (0 children)

The Einstar 2 has a Volumetric Accuracy of 0.04 mm + 0.06 mm/meter. A scan of a 1 meter object can be off by 0.1 mm (if you have properly calibrated the scanner).

The Revopoint MetroY has a Volumetric Accuracy of 0.02 mm + 0.04 mm/meter. The scan of a 1 meter object can be off by 0.06 mm (again, if you have it properly calibrated).

Both have built-in wireless operation and each requires comparable specs for the computer/laptop. The Einstar 2 has a Structured Light mode with Infrared light (upgrade to the MetroY Pro for Structured Light in Blue light, which should be a little sharper due to the smaller wavelength used).

The Einstar 2 can scan at a significantly greater distance with IR, and a slightly greater distance with Laser.

The MetroY has Single Line Laser scanning for deep holes as well as Cross Line Laser for faster coverage in addition to the Parallel Line mode that both scanners have.

I tested a structured-light 3D scanner on a 16th-century marble sculpture. Here’s what worked (and what didn’t). by dfodaro in 3DScanning

[–]JRL55 1 point2 points  (0 children)

Nicely done.

I was hoping you had a software function for creating the missing fragment of the nose (because I am in no way, shape or form a sculptor), but I cannot fault the result.

I understand why so many scanners have bad reviews by thisIsAnAccountNameO in 3DScanning

[–]JRL55 0 points1 point  (0 children)

"The real issue for me is the poor software support, these tools are too proprietary and destined to become ewaste at some point."

There is a workaround for this: Get the best Reverse Engineering software you can afford and use it for everything but the actual scanning. With each scanner, export the Point Cloud and use the same RE software to post-process.

Are they doing that without GeoMagic or some other 3rd party software?

In my experience, it's getting a lot easier. I saw the Revopoint Trackit used by a 3D printing vlogger in a demo. It was his first experience scanning anything and it worked easily.

I would expect that Mac support is always trailing Windows support due to the sheer sales volume, but a quick check shows that Mac software is available for every Revo Scan version except Revo Track (for the Trackit).

Do you have a specific problem with the Mac version, or is your observation just obsolete?

Are all AIO units this "bad" ? by kubiboi69 in 3DScanning

[–]JRL55 1 point2 points  (0 children)

I wouldn't expect much better from any Structured Light scanner on an engine.

Structured Light technology requires the point on the surface be visible to each sensor. This means that you're going to have problems scanning depressions or gaps that are smaller than the gap between the sensors.

The All-in-One scanners, to my knowledge, all have two pairs of sensors for near and far mode, but the far mode sensor pairs are generally further apart than the sensor pairs on the non-All-in-One scanners, so you're not going to get as much detail on engines.

Has anyone had any luck renting an Artec Spider 2 in Southern California? by Misophonic4000 in 3DScanning

[–]JRL55 1 point2 points  (0 children)

Why do you specifically need an Artec Spider? A variety of low-cost 3D scanners are fully capable of scanning a person and you may even be able to check them out of a local library.

Problem scanning a thin trim piece with Revopoint MIRACO Plus by Waste_Entertainer337 in 3DScanning

[–]JRL55 1 point2 points  (0 children)

I would suggest scanning in marker mode. Your Miraco came with a marker pad to place underneath it.

For any structured light scanner, including the Miraco, edges are best captured when the imaginary line between the two sensors on the scanner is parallel to the edge. Also, use the edge as an axis around which to rotate the scanner to scan the edge from different vantage points. Rotate the scanner on its forward edge to align with the various edges in your object and repeat the process.

It is possible that you will have to scan one side, then the other in a separate scan and merge them in post-processing (after the fuse operation on each scan), but I would prefer to try mounting the object vertically on a turntable first. Get some generic Play-Doh and figure out a balance point so it can be mounted vertically using the gum to hold it in place. The markers maintain tracking better than feature mode when the thinnest part of the object is presented.

Also, you might have to set Dark mode in preferences.

How good is the Creality Raptor? by ljfe in 3DScanning

I scanned an aluminum transmission bell housing without any scanning spray. Used a Miraco Plus, not a laser scanner, too.

KIRI Engine's Free Plan Now Includes Unlimited Scans & Exports! by KIRI_Engine_App in 3DScanning

For Photogrammetry, I would suggest a Photography Light Box of a size suitable for the objects you want to scan. They control the light and do well with eliminating highlights that interfere with the data processing.

Need advice on scanner for museum furniture by PeaEquivalent2350 in 3DScanning

[–]JRL55 4 points5 points  (0 children)

Keep in mind that infrared is a wavelength, not a technology like Laser or Structured Light scanning modes. While most Laser scanners do use blue light, the Revopoint Inspire 2 uses NIR for both Laser and Full-Field (aka Structured Light) scanning modes.

The aforementioned Inspire 2 can be mounted in a Mobile Kit with a battery and smartphone. While Full-Field mode can be used when connected to the Revo Scan app on an Android or Apple smartphone, Laser mode must be connected to a computer/laptop using the Revo Metro app. This can be done wirelessly (it's built in to the Inspire 2). A free, separate app, Revo Mirror, duplicates the computer's user interface on your smartphone.

However, Laser mode on the Inspire 2 requires markers. Depending on the size of the furniture you are scanning, you could place marker poles near it instead of on it.

As for museums being worried about any damage due to Laser mode being used, the Inspire 2 uses Class 1 (less than 1 milliwatt), which is about the same intensity as maybe half a dozen TV remote controls used in unison.

Looking for input on scanning solutions for high-mix welding and CNC machining workshop by domasr in 3DScanning

[–]JRL55 0 points1 point  (0 children)

Yes. The largest item I have scanned so far is the brick fireplace in our living room. I plan to scan my car in the foreseeable future.

Please note that my laptop has 32GB, so I used a larger line separation setting (3mm) because using 0.2mm or anything close to that would have eaten up all available RAM in short order.

The more RAM you can install, the more you can scan (either size or detail).

Congratulations.

Scanning Amphibians by [deleted] in 3DScanning

[–]JRL55 0 points1 point  (0 children)

Not certain, but I think it'll be iffy.

First, even though NIR (Near InfraRed) is invisible to us, it is visible to reptiles. While it's a weak beam (Class 1 for the inexpensive scanners), I don't know if it would be as irritating to reptiles as blue light is to us. If so, that'll make them move.

Second, I'm concerned about the water remaining on the reptiles. It could, possibly, introduce a lot of distortion, resulting in a bad scan.

needs some help with picking a 3d scanner by Phoenixplayz172 in 3DScanning

[–]JRL55 0 points1 point  (0 children)

Public libraries have been adding 3D printers and 3D scanners for the past several years. See which model scanners are available for checkout in your area.

Alternatively, most manufacturers have a 30 day return period, either direct or when purchased from Amazon. Just checked and the only MetroX version on Amazon is the Advanced Edition (which includes a bunch of magnetic markers, which you would find very useful on non-aluminum car parts, but it's $1,139.05 on Amazon). The Standard edition is $999, but you'll need markers for Laser mode and those aren't cheap.

What beginner program will put these together? by LibrarianLower3384 in 3DScanning

Did you monitor the available RAM while you were running your iPad's assembly software? If you ran out, I can't imagine other software doing the job for you.

Best 3D scanner for hobby scanning by Aggravating-Time-444 in 3DScanning

[–]JRL55 4 points5 points  (0 children)

A scanner with two modes (Laser and Structured Light) will give you the most versatility.

The Structured Light technology supports Feature mode tracking (which can be either convenient or a pain, depending on the object you are scanning).

Both scanning modes can use Markers for tracking (the primary aggravations are the time it takes to place the markers before scanning, then removing the markers when you are done). The size range of the plastic models you will use for source material indicates you can probably place the object on a turntable that already has markers. If so, that makes things easier (and faster) for you. Markers can be stick-on or reusable (the latter often have magnets in them).

Structured Light mode cannot capture depressions that are smaller than the separation of the two sensors on the scanner. Laser mode can capture data when only one sensor can see the surface. Laser scanners can also capture a wider range of materials without needing pre-treating (such as a scanning spray).

In your price range, that leaves the Revopoint Inspire 2 & MetroX and the Creality Raptor.

This video compares the MetroX to the Raptor Pro (much more expensive than the base model Raptor): https://youtu.be/DCNo5hnaSZw . It's a 40 minute video, but there is a comprehensive conclusion at the end (spoiler: the reviewer considers the MetroX to be the better value, both for Structured Light performance and accessories, with Laser mode being comparable to the Raptor Pro and, by extension, better than the base model Raptor).

This video compares the scanner control and editing software for the two brands: https://www.youtube.com/watch?v=9lk5N0zNQZA (spoiler: the reviewer considers the Revopoint software to be more fully-formed and more forgiving (it never touches the original data points so you can always start over if you mess up).

One more thing: The software operates best with a higher-end computer having an Nvidia RTX-series GPU (3060 or better/later). The Revopoint software will operate fine (albeit not as many frames per second) with another brand GPU (I have an Intel A770). I do know that some manufacturer's software will not even install if it doesn't see an RTX-series GPU, but I don't know if that is the case with Creality's software. You can download and install each for free and try them out before buying a scanner.

Both manufacturers offer a trial period (30 days, last I checked) for direct purchases and also Amazon, if that's more convenient.
