00:00You know, 3D scanning has been around for a while, and the rate at which industrial-level technology is reaching the consumer level has kind of blown my mind.
00:09I mean, we're getting into some Star Trek-level stuff here, so we're going to take a look at Creality's latest Raptor Pro.
00:17This is on the expensive end of the consumer level, but what it's able to do really kind of blows my mind.
00:24So it has three different scanners built into this. There's a near-infrared scanner, and, you know, that's pretty typical of what you'll have in just about any scanner, and it works okay.
00:34But you wouldn't buy this just for that. The reason that you get the Raptor Pro is for the blue light lasers, and it has, like the original Raptor, the seven parallel lines, and that works pretty well, but the field of view is really small.
00:48And so, you know, if you're trying to scan larger stuff, it takes a long time, and you have to put a ton of different markers in, but this one now has, in the Pro, a 22-line cross-hatched pattern, and that is crazy fast, and it covers a much larger field of view and saves a ton of prep because you don't need so many markers everywhere to be able to cover your project.
01:11So we're going to try out all those different modes on a few example scans here, and then even use some scan data to design a little product.
01:19But before that, I had to unpack and calibrate this thing. Let me show you how I did that.
01:24So here's the package, and inside it was put in a really nice protective case, and I always appreciate that when you're getting something that's somewhat of a precision instrument like this to keep it safe and in good condition, and then have a place for everything to go.
01:39So it's a nice touch. Those boxes house all the cables that you'll ever need for various plug adapters, and underneath the foam there is an additional foam insert that has your calibration plate on it.
01:52So this has strategically placed markers, and you look up the actual serial number of your plate so you can be confident that you're calibrating to that particular plate.
02:03And so it walks you through a calibration routine where you have to come at it from different angles and different heights and hit each spot.
02:12Now that this is all set up, let's go ahead and take a look at the near-infrared mode.
02:16Now, like I said before, this isn't the reason that you bought it. I see it more as a bonus here, so we'll just take a quick look, and then we'll get on to the blue lasers.
02:24So I'm going to start off by scanning a bandsaw. Now, one of the benefits of the near-infrared mode is that you don't need to put on any kind of targets or markers,
02:34but the drawback is that it can miss certain, you know, textures or colors like that.
02:41So this has a lot of different types of colors on it and a lot of different features, so I thought it'd be interesting to see how this portable bandsaw actually scans into there.
02:50Now, while I'm scanning, one of the biggest challenges is to maintain tracking, and it has to mathematically follow along with this geometry.
02:58And sometimes it would get lost like that, but it would find itself once again.
03:02So this isn't the absolute best near-infrared scanner I've used, but in the end, it's still really cool to be able to take an object and make a scan like that.
03:13And obviously, there's plenty of usable geometry here. I wanted to look at a contour. Now, if you have completely flat faces, sometimes it'll just run away like all of them do,
03:24but this has a slight contour to it, similar to an auto body panel, what it might do if you're trying to match it with a bumper.
03:30So I thought this would be an interesting example scan that I could show here in the shop, the side of this generator, and it worked out pretty well.
03:37It was able to follow and track along. It had just enough curvature for it to be able to keep track of where it was.
03:44And after I went over it again and again, I got pretty good scan data there on the side on that blue panel,
03:53but it didn't pick up the black plastic panel on the back.
03:57And so if I wanted to pick that up, I'd need to use some kind of a scanning spray, like a white powder spray.
04:03A lot of people use like that foot spray from a pharmacy or whatever, and that can give you just a different texture to be able to pick up.
04:10But overall, still pretty cool, given that I did no preparation for this at all.
04:16All right, so you can see how that would be useful if you don't want to go to any preparation,
04:19or you might use that mode to scan faces or bodies if you're into the figurines or whatever you want to do with that.
04:26But let's get on to the blue light laser mode and see what we can do with this.
04:30So let's start off by scanning the same object using both the seven parallel lines and the 22 line crosshatch pattern.
04:39So I'm using this smaller lathe chuck, and I'm going to scan it with both the seven line and 22 line methods.
04:45And then I'm going to actually check the scan data and compare that to the real diameter of the chuck using both methods.
04:52I need to prepare it with a lot of these targets, and I stuck those little magnetic towers that I'd 3D printed earlier on the table around it.
05:01And that just gives me something else to look at here with the scanner and help keep tracking around this thing.
05:07So I'll follow around it, and I'm relatively close to this to be able to scan with the seven lines like this.
05:16And you can see it starts to pick it up right away.
05:18There's not a lot of tracking issues when it's working with markers like this,
05:23so I can just follow around and get a pretty good representation.
05:27But I do have a small field of view here, so it takes a bit longer to work my way around.
05:33And the markers have to be fairly dense to be able to pick them up.
05:37Now, after I've got some scan data, I want to clean it up a little bit and just delete the portions that I don't need.
05:44So I can just trim away at it until I get what I want.
05:48And then I'll use their one-click processing.
05:50I never changed any post-processing parameters.
05:53I just used their automatic mode, and I got this result, which looks really nice.
05:58We'll export it and measure it later to see how it compares to reality.
06:03But definitely usable for these smaller parts, but I want to try it with the .22 crosshatch lines here.
06:10So with the .22-line laser, notice how much further back I am, and it's picking up a huge area.
06:18And so as soon as I start scanning with this, I mean, it picks it up.
06:22Let's just look from the beginning.
06:24So as I start right now, look how much it's picked up immediately.
06:28This is in real time, and as it turns green, then you have enough scan data to reconstruct from with a high level of confidence.
06:37So it's already, you know, basically done after I work through for that short period of time, and I can once again trim that data down.
06:47I mean, even look around the outside, how much of my welding table it was picked up, and it has the lines in between and the holes and everything right in place.
06:55So it picked up a lot with that.
06:59And then the scan honestly looks pretty similar in this case, but it was much faster to achieve.
07:06So let's compare this to the actual diameter.
07:09So this is measuring just a touch over 100 millimeters with calipers.
07:14Somebody's commenting right now that a mic would be more accurate, and that's true, but I'm doing this today.
07:19Now I can fit a cylinder to the outer diameter and compare here the deviations.
07:24So its maximum deviation is about a tenth of a millimeter, so that means that my cylinder is picked up, you know, pretty smoothly.
07:31And when I look at the diameter, it's oversized by about a tenth of a millimeter, which is, you know, four or five thousandths of an inch.
07:39And that's like the diameter of a human hair.
07:42So when you consider this was picked up with a fancy blue flashlight, that's pretty impressive right here.
07:48But it did take a bit longer.
07:51Now let's look here with 22 lines and do the same thing.
07:54So I'll import this and then fit a cylinder to the outside.
07:58And the max deviation, once again, is about a tenth of a millimeter.
08:01So it did fill in pretty smoothly.
08:03And if I check the diameter of that cylinder there that was the best fit statistically,
08:09once again, it's about a tenth of a millimeter over, which is somewhere around the diameter of a human hair.
08:17So pretty impressive.
08:19If you ask me for a consumer level scanner, it is at the high end of the consumer level,
08:24but with this cross hatching, and that is fast and accurate.
08:2922 lines.
08:29That was a lot faster.
08:31Let's go ahead and try that out on a little bit larger, kind of a medium-sized object here.
08:35All right, so I'm going to scan this bench vise here because not only does it have a lot of intricate shapes,
08:40it has bare metal, a shiny finish, and some black on it.
08:44All three of those things can be difficult to scan.
08:48And so the only prep I've done here is adding the markers.
08:51And this is in real time.
08:52Look how quickly that emerges.
08:54And as it turns green, that means I've got all the data that I need for a good quality scan.
09:00Now when scanning, you can choose how long to spend on each area
09:03to get the fidelity that you need for your intended use, right?
09:06So you might spend a lot of time on a small area,
09:09or you might spend, you know, a short amount of time because you just need a basic volume.
09:13So you can really tailor it to your use case.
09:16But I'm getting a pretty impressive model that's capturing all of those different textures here in place.
09:24Now there are a couple of holes that I could have spent a little longer on,
09:28but look at the details that you have.
09:29And I mean, even look at the welds on there, the welded features.
09:32You could actually take a record of, you know, all kinds of weld inspections with this.
09:39That would be an interesting thing to look into.
09:41But, you know, when you're just looking to interface with something,
09:45that's an incredible level of detail, in my opinion, for a consumer level scanner.
09:50So the real beauty of 3D scanning for me is to be able to design products that interface with other parts,
09:57whether that's fabricated products or, you know, 3D printed ones.
10:01I want to start off with a simple example here.
10:04So I'm going to go ahead and scan the body of my tungsten grinder.
10:08So this is like a fancy pencil sharpener that I use to sharpen tungsten electrodes for TIG welding.
10:13And I want to keep it right at hand on my welding table.
10:18And you could try to do some fancy tricks to measure this around here.
10:21But if I could just take this geometry and scan it in,
10:24and then build something around it that this can sit in, that'd be really nice.
10:30So let's go ahead and grab some scan data, model something around that in the computer,
10:343D print it, and see how that works.
10:36So I'm scanning this here on its side, and I'm prepping it with some markers.
10:42And I also have those different pyramids that I'd 3D printed.
10:46Now, I could have stood this up on end to scan around the whole outside of the handle,
10:52but I didn't because, honestly, I didn't think about it.
10:54And I can assume that it's symmetric.
10:56So I'm really just going to use half of it and mirror this over.
11:00Now, this is in real time.
11:02You can see how quickly it's picking it up here in my scan data using those 22 crosshatched lines.
11:08And so this is less than a minute to pick up all the geometry that I'm going to need to work with here in the actual part.
11:18Now, I'll trim off the front end because I'm not going to interface with that.
11:22And honestly, I could trim off a little bit more to make the model smaller,
11:25but I'll just leave it as is because it's not huge anyway, at least for the computer that I'm using.
11:29So I can export this out as a point cloud.
11:34There are a bunch of different file formats you can choose from, but I'll just use...
11:40I think I ended up turning into an SDL here to bring it in.
11:43But either way, you can see how the geometry came into Fusion 360 right there.
11:47And then I was able to model around that surface to create my part.
11:53All right.
11:53Well, here's the finished product.
11:54I have my holster right here and it has a slot so the cord can go through and it can drop right here with a spot for the switch.
12:04And then it has a pair of pegs underneath that can engage right here with my welding table.
12:11If I can line that up.
12:12There you go.
12:13And then it's right at hand.
12:14So that worked out really well.
12:17So overall, my impressions of the scanner performance, the 22 line laser mode, that's how I'm going to use this.
12:25It just plain works.
12:27You don't have to do nearly as much prep with the markers.
12:29The seven line could be handy if I'm working with some small intricate features, but I'll probably use that a little bit less than that 22 line laser mode.
12:38The near infrared mode, in my opinion, is just something that you might consider a bonus, that you're getting a blue light laser scanner.
12:47And it'd be nice to have this once in a while for different things.
12:50Honestly, it's not the best performing that I've used on the near infrared side because of some of the tracking errors that we saw as we were working through the scanning.
12:59That said, it is still totally capable of getting a scan.
13:02So thanks a ton for tuning in.
13:04If you want to check this out and see the full details and specs or pick one up, there's a link in the description.
13:08We'll see you next time.
