I've been trying out the David lasescanner trial version and getting excellent results.
I bought a cheap webcam and 2nd hand DLP projector, both for under £100.
So if I buy David 4 at £300 that's under £400 for the lot.
SLS scanning is also way faster than scanning with a laser. The setup I have takes less than 60 seconds to do a full 360° scan.

We recently posted a roundup of the 11 best value 3D scanners on the market. You might find it useful as a quick rundown of what's out there for under $3000 USD

Thanks, appreciated.
I can PM you my email address if it would be easier to send it.

I'll upload it later this evening. I'll have to figure out how, though, ti's a lot bigger than the 5MB limit here.

I'll figure something out.

Yeah, been running compute normals with various values in the Neighbour Num box.
Is there any chance you could upload the PLY file for the Hello Kitty scan you did ?

What exactly do you mean by "pretty much the method".

Did you do ALL the steps involved? From the looks of your result, I would say you didn't run the Compute Normals Filter. You point cloud doesn't look coherent.

That's pretty much the method I'm using but I just can't seem to get a mesh as smooth looking as yours.
If I set an Octree higher than 7 in Meshlab it just hangs.

It actually produces a pretty decent looking point cloud once the object has been scanned and only takes about 5 minutes or so at high resolution.
But I haven't yet found a method of converting the point cloud which produces a decent mesh without losing a lot of the detail.

Check out the Sticky in the Atlas 3D section entitled "From Scan to Printable Mesh Tutorial"

Hidden bits are why you need to scan multiple times changing the orientation so the lasers and the camera have a chance to see all of the figure (which is why it tends to take hours and hours because each scan takes a long time). An action figure likely has another problem: Unless you can lock all the bits so they don't move relative to each other when you re-position it, the software probably won't be able to combine the scans since the object won't be the same shape in each scan. Plus action figures tend to be shiny plastic, which causes reflections, which makes lots of noise in the scan.

How does it do with irregular objects that have areas of occlusion (like an action figure for example).

Yep. M&F's "native" format is their own proprietary format that stores all info, but you can save it in a lot of other different formats, some of which discard color. Other than cleaning up the scans and combining multiple scans of the same object, there isn't a lot of editing you can do in the M&F software. I use things like meshmixer to convert the hollow STL files M&F produces into solid ones so I can slice them in openscad.

does the Matter & Form scanner have an option to scan the surface into a cloud/mesh and ignore the color/texture information?

If so, when combining the various scans, it looks at mesh/point cloud references to do this, or does it use image information?

Re: 3d scanner shopping

I will say the matter & form scanner has a pretty good solution for irregular objects: You can scan the object multiple times sitting in different positions and orientations on the turntable, and use their software's "combine scans" feature. It seems to be pretty good at recognizing how to combine them by identifying shapes that are the same in multiple scans.

Of course, that means it takes even longer, and if you want a color scan, that doesn't work too well since the different positions tend to have different shade and the colors don't combine all that well.
