This is amazingly promising for lots of projects... I'm still waiting to make the 3d printing jump but looking forward too it more and more.

Indeed. I primarily purchased the scanner so I could create a digital archive of my rare resin-cast 1/55 parts before I use them on projects. I held back on making the jump to 3D scanning and printing for many years because the accuracy of both pieces of equipment wasn't great. Now with relatively affordable desktop scanners and commercial printing services out there, both with accuracy in the 0.1mm range, I'm optimistic. It still helps to know what you're doing on the technology side, especially with point clouds and meshing, but the software is a lot more reliable and easier to use these days. Resin casting is still a fantastic option if you have the knowledge and equipment to do it right.

Will you be modifying or upgrading any parts?

Swivels at the knees and double jointed elbows is all I’m saying.

That would be the bomb! I still need to convince my library to let me 3d print a gunpod and super armor, but they're not thrilled at the idea.

Crowd fund your own printer. That way you only have to ask yourself for permission.  It’s for heritage so would be legit. I can hook you up with configs and what works etc. I’m sure others here will also.

My first goal is to get more parts to scan well. So far, so good, but I'm still running tests. Having the scans as baselines would make it a lot easier to create modified or upgraded parts to allow for more articulation and accuracy.

Could this be  the start of a 1/55 resurgence.

3d printing doing the things that we just couldn't do practically 10 years ago.

That is what I'm hoping for. Long live the Chunky Monkey! I need to get back to my big 1/55 customs project, too....

My computer cannot handle a 3D printer; it's on it's last legs as it is.

Ender 3 doesn’t need a pc just use online based CAD and use the power of the cloud to build Stl files and copy to men card done.

Thanks for the info, but pc cannot handle the online CAD either (tried in the past and blew a RAM card in the process). I think I'll just settle for the valk i have.

Quick and dirty single orientation scan of a GBP armor part. Lots of work still to do, but very encouraging.

When you scan a part this large do you only scan the exterior and then the interior? Or is it a single 360’ scan?

The part is on a turntable. My scanner's turntable moves a fixed number of times to complete a full circle. Each time it stops, the laser "sweeps" across the part to create a 3D image. All of the images from the full rotation are assembled to create the model. To build a better 3D model, you scan the part a few more times, changing how the part is placed on the turntable. That way you can cover the exterior, interior, and any other nooks and crannies. Most other scanners have a fixed laser and slowly do a continuous full rotation of the turntable to scan the object. I picked mine based on reported accuracy (0.1mm) and apparent scan quality, but as I've started scanning parts, I'm not convinced my scanner is the best one out there in this price range. I might return it for a different one that gives me more control.

Edit: I just decided to return my current scanner after doing some more research on its closest competitor. I think I'm going to like this other one *a lot* more. Stay tuned for more scans. Probably towards the end of next week.

I have 1 more 1/55 I want to customize. I got everything except for the heat shield. But depending on how things go here I may be up for more parts. 

Definitely watch this space for updates. I'm now invested in trying to make this work for our community. I may hit a functional limit on what I can do without dropping some serious cash on professional-grade scanning equipment, but we'll see where we end up. Right now my wife is tolerating this new hobby, but if I buy a $5,000-10,000 scanner to get better results, she'll kill me.

So which scanner are you going to pick up? I’ve been looking a bit at the options.

The first one I bought was the Scan Dimension Sol 3D. I'm returning it. The software is absolutely terrible and you get no control over how the scanning and model construction is done, so it fails a lot of the time. It arbitrarily limits you to no more than five orientation scans and it decimates the resulting point clouds and meshes for some reason, so you lose a lot of detail right off the bat. The sizes of many parts I want to scan fall between the two fixed volumes it supports in its "near" and "far" scan positions, which is really frustrating. It's also really, really, really slow. I think the manufacturer was going for push-button simplicity and it just doesn't work. It's main competitor is the Matter and Form v2, which I just purchased and is hopefully arriving on Tuesday. It's a bit more expensive, but their software seems to give you a ton of control and the speed is much better. Both advertise 0.1mm scan accuracy, which is two to four times better than the entry level systems (for two to four times the price, of course). The next models up the scale are from EinScan and they cost two for four times as much for 0.1-0.05mm accuracy. After that, I think you're looking at $10,000 or more for a truly professional-grade scanner.

Wound you be able to scan something let's say 18x18x18" with the new one you have coming? Is it easier to deal with if you only want a 2D scan of something? For example I find myself needing to pull bolt patterns off of stuff a lot that I can't get coordinates for. I've had to put entire engines (guts removed) in the mill and manually locate all of the points. It......kinda........sucks as I'm sure you can imagine.

These desktop scanners are generally limited to scanning the equivalent of a cylinder that is 6-7 inches in diameter and 7-10 inches high, with a max weight of 2-3 kilos. My new one is at the upper end on all three counts. To do what you want, you'd likely need access to a nicer handheld scanner. This review includes several options, starting at #12 on the list:

https://3dsourced.com/rankings/best-3d-scanner/

The ones at the end of the list are jaw-dropping in terms of speed, accuracy, and price.

If what you really need is a 2D map of a surface with patterns on it, you might be able to use your smartphone (or a nicer camera) and some photogrammetry software. The idea is to take pictures of the surface from multiple angles to reproduce something like human stereo vision, which then lets the computer estimate the distance from your camera to the surface. You can usually create a good 2D map from that distance information. The approach is a lot cheaper and more accurate than it used to be (I've been doing this photogrammetry thing professionally for a loooooong time). This is a photogrammetry project with free software that one of my staff came across recently:

There are lots of non-free options like Agisoft PhotoScan that are also good.

I have an update on my 1/55 part scanning project. The new scanner is a bust. The first one (Sol 3D) had good hardware, but crappy software. The new one (Matter and Form v2) had good software, but crappy hardware. I can't win. I've learned a ton from observing how both of them worked, though, and unless I want to drop $8K on what I need, I think the best thing for me to do is build my own scanner. Normally that would be crazy talk, given how complicated these systems are, but luckily this lands right in the wheelhouse of my professional training. I've spent this weekend going over all of the math, imaging science, photogrammetry, and engineering involved and it's doable. It basically comes down to how much time and money I am willing to spend on this. The entry-level desktop scanners I've tried all cut corners on the hardware in a few ways that I think I can address with slightly nicer components--since I actually know what I'm doing. Right now I'm shopping around for all of the parts I'll need. It's not going to be cheap, but I think it will end up costing me roughly the same amount as the scanners I've tried.

If I get the system right, we'll be able to scan all kinds of stuff.
