It's pretty fun. I started scanning everything in sight. The file sizes are pretty big though. This scanner is on sale this weekend (I think everything is on sale) on the Creality website, the link in the pinned comment takes you there. There are a few others out there too but I haven't seen reviews saying one is better than the other unless you get a super expensive one

Mine is on the way! Checking reviews for tips, lo and behold one of my favorites has posted a review!

It's necessary for my wife, she has scoliosis so even clothes that are the right size don't fit. No more problems! She can make/adjust to the form and it's perfect

I'm new to the scanning scene but have been printing for about a year and a half now. Just picked up the Bambu Lab P1S a couple of months ago and this fu@ker is lightning fast compared to the Creality Ender 3 V2. Any tips would be appreciated.

you can close the gaps that the face-mask leaves with 3d-printed rubber-pieces, stuck on the mask. Of course, you´ll use the 3d-model of your head, to find out the form of those rubber-pieces.

A couple of tips, from watching the video. First, yeah hair sucks to scan. I recommend a swim cap. Second, scanners track their own position via relative motion of "the thing they're scanning" (which I generally refer to as the subject). If the subject changes shape or position relative to its surroundings (assuming those surroundings are also in the scan), then the scanner is going to have a hard time tracking its own position. To help, usually adding "tracking targets" (also called tie points) will help, but in the case of your face, making your neck harder to scan would actually probably help, since your head can move relative to your neck. In which case, wearing a black velvet cape would probably do the trick, it's like an invisibility cloak for the scanner. Third, besides adding tie points, Clough42 showed off this cool spray he got specifically for scanning. It's sort of like "frost in a can," you just spray it on and it'll sublimate on its own after a few minutes, but it'll last long enough to get a good scan in, and mitigate the black/shiny surface problem. Probably don't spray your face though. Fourth, if you want to scan something like a banana, but you need to flip it, you actually can scan the top, flip it, scan the bottom, and the software should do a decent job of aligning the top and bottom ASSUMING that the area of overlap between the two sides is both detailed and sufficiently large enough for the software to do it's thing, and that the background has been removed (or is just invisible to the scanner). Fifth, the scale factor on these things requires calibration, but short of a calibration tool that the manufacturer provides you, you can just scale your scan up or down after the fact, for instance in blender, as long as you scan something with a known size for reference. Generally speaking, the bigger the better (you'd prefer to interpolate the scale of your subject rather than extrapolate), as long as your size gauge can be scanned from effectively one position. Regulation sports balls actually tend to work fantastically, because you can really accurately estimate a sphere's radius from the points on its surface, and you can easily verify their diameter yourself. I once built a calibration field using just a 4'x3' sheet of MDF and about 60 ping-pong balls.

@PaulsGarage

9 ай бұрын

Wow thanks for the info! I've seen the spray but I haven't tried it yet. And that's a great idea with the black felt to make things "invisible". I never would've thought of that. So are there scanners that work better with surfaces like hair? Like maybe ones with laser scanning? I've seen larger industrial scanners that work really quickly, but it seems like they shoot a laser and/or have more cameras, some of which are farther apart. They aren't exactly a couple hundred bucks like this one but the technology seems a little different. As far as I know this does not shoot anything out. Is there a benefit to having more cameras and at different distances? I assume you could have more flexibility that way? And thanks for the info on calibrating the machine. I never bothered to do that, and to be honest I never checked to make sure the finished result was perfect either.

@@PaulsGarage Re: Hair, not really just because strands are so hard, but if you comb your hair flat and add way-too-much hair spray it might work well enough. Basically you want a mass of hair, not strands. Those kind of scanners with the cameras and laser are what I call triangulation laser scanners, and can be quite accurate indeed (talking sub-millimeter), but for that sort of accuracy you need a totally independent method of locating the scanner. One method is to have the scanner attached to a "robot" arm, except instead of motors, it's just encoders on the joints. That way, with the right calibration and precise measurements of the relative angles at each joint, the scanner's position can be known relative to the base of the arm. Your scanner there is a triangulation scanner too, but it's using an infra-red projector to shoot out a pseudo-random pattern, that the infra-red camera can then measure the parallax of. With the known separation of projector and the camera, and the (what boils down to, mathematically) angle of the parallax, the you can determine the depth in the image. BTW, the black-and-white speckled image below the coloured image is the infra-red image captured by the scanner. For the same reason in my comment before, the larger the off-set between the camera and the "thing doing the projection" (infra-red camera, or laser), the better precision in scale you'll have, but at the expense of being able to resolve smaller details, since you just get bigger projected pixels. Also, ideally, you'd want a 90 degree intersection between the center of the camera's perspective and the center of the projected infra-red image, but obviously that would exclude half of the subject, so compromises are made, and for your scanner they're nearly parallel. However, for the laser scanner, it projects a line, and as long as the camera can see that line, they can have a very steep intersection angle, giving a very clear depth measurement. But now I'm on a tangent. Yes, having a larger separation has the benefit of giving you a larger measurement volume, but like I said, trade offs.
