Summary

This gnome is part of the growing collection of objects we've 3D scanned with the MakerBot Digitizer Desktop 3D Scanner. Just two lasers, a turntable, and a camera generated this watertight, 3D-printable model in about 12 minutes.

The original object was designed in ZBrush by MakerBot designers, and then printed on a MakerBot Replicator 2 and painted. We then scanned that object with the MakerBot Digitizer and are sharing it so you can continue the creativity! To compare the original version with this 3D scanned version, click "MakerBot Gnome" under "Derived From".

With this STL file, you can modify, improve, or remix the gnome in any 3D modeling program just as you would any other 3D model designed on-screen.

Resize him and turn him into smaller pieces for a game or diorama 3D scan a model car, scale it up a bit, and put your gnome in the driver's seat 3D print him on a MakerBot Replicator and paint him

You know the deal. Explore, and have fun!

So overall how much accuracy is lost after scanning the object and printing it again?

Nearly looks like this is 'one-layer vasable' so i tried it. Used slic3r --scale 0.6 --bottom-solid-layers 0 --spiral-vase GnomeScan.stl came out okey, but not quite good enough, the top of the feet above the goggles and shoulders fall in due to lack of space.

Of course i didnt quite expect success due to the horizontal bits, had a very low speed of operation in this occasion, though so it might work a little better at higher speeds.(or not) Perhaps if multi-layered spiral prints were implemented it would work better.

Come on, guys! This is a nice scan made with a relatively inexpensive tool. I used to have a 30K+ Creaform scanner and it
sucks given a price/quality ratio. It won’t fetch better results than this.

I had NextEngine and sold it because it is not user-friendly for dumb-heads like me. Kinect or similar technology based scans would give you a much more” abstract” scans (less detailed). David laserscanner may be cheaper but requires a lot of learning, tweaking and in the end is not that powerful.

So I think this is just a good product, maybe slightly overpriced. I can’t judge since I don’t own Digitizer and can’t test the software where the post-processing is a core in scanning.

"Exported from Blender-2.67"? Why does the stl file show this exported from Blender? Does the Digitizer require Blender? I thought it scanned straight into Makerware.

This is an ugly scan from a unit that costs half as much as my MUCH BETTER nextengine hd scanner. This thing shouldn't cost over $500, the quality is terrible, the unit is extremely limited being locked down to only 360 degree scans, no ability to stitch one button idiot proof results. Here's one for makerbot, lets see how well your scanner can scan a C3P0 figure. The reflection will give you trouble, but it can be done easily with the right product, do you know how to do it? For $1500, you should include a can of the product with every order.

Sorry while the Digitizer might seem nice, that $1500 price tag is too much for a fancy laser scanner. I think the David 3D scanner is cheaper, and if someone has the right stuff they can do it free with 123D Catch.

Will you be publishing the original non-scanned model? The one used to print the model that was scanned?

It's listed under "Derived From" now.

Can someone explain the advantage of the two laser approach.

The scan process works by taking advantage of the difference in angles between the camera and the laser. They are (it's assumed) both pointing at the same place so the displacement of the line will reveal the contours of the object. However what if there's a large protrusion, like a nose, that obscures the line as it turns? The result is a "shadow" of area that isn't filled in on the point cloud behind the nose. The solution is another laser on the other side to catch the geometry on that side of the protrusion as it comes around. And since the lasers are offset left and right it's easy for the software to figure out which line is which by splitting the analyzed area down the middle.

Hrm, scanned gnome, I feel the hand of Tony Buser at work

Hmmm, 3D scanner. I feel the hand of Tony Buser at work.

Scanning a print... I love it! Came out awfully clean, too. Nice work.
