This is a 3D Scan taken with the prototype Photon 3D scanner from Matterform.

The pillbug scan is one of my own unfinished sculpture experiments I did while designing a new sculpture so the CC is open. Do with it whatever you want.

We'd love to see it printed on whatever printer you have, whether it be a replicator, ultimaker, printerbot, burritobot, or Dimension printer.

The first print pictured is by Mike Hellers and was made with a Makerbot Replicator, 0.2mm Layers and natural/white ABS.

The powder one was printed on a Zcorp and scaled down to 50% by Marthijn

This is a generic hand grip,can convert your motion detector to 3D scanning machine. Either Xtion or Kinect you just only need simply put the rubber band to fit the scanner on top of the grip. Then you can immediate convert your motion detector to 3D scanning machine. enjoy

This is a 3d Scan of a dragon head sculpture we made in clay, it was to test our new nextengine 3d scanner, The actual item stands 12 inches and is 6.5 inches across at the widest points. I'm giving this info in case the amount of plastic used to print is of concern. We have a Han Solo frozen in Carbonite that was actually gift wrap we made for an Ipad mini that I will scan and put up if anyone is interested, we're still learning how to use the scanner and are having difficulty with that model.

I'm futurejames and I have a hoarding problem. Namely, hard drives. Just can't seem to throw them away. I also needed a turntable for some 3d scanning -- nothing automatic just something I could turn by hand.

This is actually a photoscan of a bust of a Russian poet Mayakovski. The original is located in central Moscow. It’s funny but the bust and the museum are embedded in a newly build former KGB buildings. The museum is actually located in KGB!

I just liked the sculpture which is quite brutal. I like Mayakovskiy as well.

Since Mayakovski committed a suicide in 1930 ( I could be mistaken with a date), I made auxiliary model with poor guy’s head blowing away. I am afraid tiny scull connectors may not be possible to replicate.

This requires the makerbot 3d scanner "cyclops" kit. It does not allow derivatives but it is located here... thingiverse.com/thing:4271

Sorry for poor documentation but the text and photos should be sufficient for those who are interested.

These printed parts are used to help the Optoma PK201 Pico Projector fit into the laser cut plywood housing of the Makerbot Cyclops 2.0 3D Scanner.

The wheel part allows you to adjust the focus of the projector whil it is in it's housing. It needs to have a rubber band or o-ring placed around it to give it sufficient grip though.

The cube part is placed against the bottom right rear corner of the scanner as you look into the lens, and acts to keep the rear of the projector in the correct location.

Some modifications are needed to the laser cut plywood parts too to accommodate the non-standard projector and these additional pieces. The hole on the rear panel needs to be enlarged, a hole for a bolt to hold the 3D printed focus wheel needs to be made in the bottom panel, a wide slot on the right panel needs to be made for the edge of the focus wheel.


The bolt hole for the focus wheel is 3mm in diameter with its centre 26mm from the front edge and 10mm from the left edge of the bottom panel
The slot on the left panel is 8*30mm with its bottom left corner located 20mm above the bottom edge and 13mm from the left edge.

The enlarged slot on the rear panel is 20*62mm with it's bottom left corner located 13mm above the bottom edge and 32mm from the left edge.

You will also need to enlarge the hole in the front of the device to allow the lens from the pico projector to project properly. The hole should be rectangular about 20*15mm starting 18mm from the bottom edge and 45mm from the left edge of the front panel.

This is Bre Pettis of MakerBot fame frozen in Carbonite.

Unfortunately, no matter how hard I tried, I could not get this to render in OpenSCAD, so I had to kludge it together in MeshLab.

I am printing now. Not expecting the best results. But we will see.

Structure from motion is a class of algorithms that take information about point correspondences between images and use them to reconstruct 3D scenes. While some pretty serious math is involved, no specialist hardware is required aside from a camera.

We've seen lots of structure from motion based 3D scanning solutions already this year, the best known being my3dscanner.com/, but all of them are closed source. This is hard to deal with when I see cool things like Qi Pan's ProFORMA software (http://www.youtube.com/watch?v=vEOmzjImsVc&fmt=22) but can't use them or look at how they work. There's been plenty of good open source innovation in laser based 3D scanners, but very little on the software side of scanning, which kind of surprises me given that software is usually the area that people think of as conducive to an open source approach.

So for my computational photography final project last semester I set out to make an open source SFM scanner in Matlab, since a lot of toolkits were already available to do the heavy math part. Unfortunately I won't have much time to work on it this summer, so I decided to release the code now to see if anyone could do anything with it.

The program starts with either user input images or input from a webcam, extracts feature points using David Lowe's SIFT, attempts to remove outliers using the MAPSAC algorithm from Philip Torr's toolkit, then uses Vincent Rabaud's toolkit to reconstruct the 3D positions of the points. From there Liugi Giaccari's implementation of the Crust algorithm is used to find a surface mesh automatically, and a function by Andreas Richter I found on the Matlab file exchange to export an STL file. The end result is that you can (theoretically) go from photo capture to STL output without any user intervention. In practice you might be better off exporting the point cloud and meshing it with Meshlab or some other program.

As of now I have only written a function to extract structure from 2 images using the normalized 8 point algorithm. I think this might require a stereo camera setup, which you might be able to approximate using just one webcam. More importantly, SIFT is not a very good detector for getting dense sets of features, and 2 images will not give you much to work with, so results as of now will be poor to unrecognizable. Fortunately all the code is pretty modular, so switching in a new feature detector or making other modifications should work fine after transposing a matrix or changing some variables.

Vincent's toolbox can use quite a few different methods, most of which are much better than the 8 point algorithm, but it needs either calibration data or more than 2 input images. Implementing affine and metric upgrades would be even better. I'm hopeful that this project will progress to the point where it is possible to make use of these methods, and I'll try to answer any questions anyone trying to add to what's there now might have.

If you're interested in more detail on how everything was done you can read my final project report, attached below.

This is a laser scanning system that I designed to use with DAVID 3D Scanner software. I have yet to buy the software, but the free version really lets you try out everything before you buy...you can at least take some high resolution screenshots of your scans. You can save low resolution files and use meshlab to assemble them.

The first scanner I designed was complicated and used gears and a stepper motor, this one works much better. It's cheaper, requires no electricity to move and has less parts. It even tells you when it's done scanning!

It uses a Taylor kitchen timer, this is a mechanical wound timer that you can purchase at Target, for about $3 PN: 5833-21

When combined with custom makerbot parts, two M3 screws/nuts and a red or green focus-able line laser you have a nice smoothly sweeping laser system.

This OpenSCAD script will generate a grid pattern of small cuboids attached to a large flat cuboid.

The heights of the smaller cuboids will alternate sequentially.
The user can specify the number of rows & columns as well as the length & breadth of the smaller cuboids and the separation between adjacent cuboids.
The Number of different heights and the difference in height between smaller cuboids can be specified too.
The user can also choose whether or not to add Keyed connectors so that they can print multiple items that can then be easily connected together to for an arbitrarily large grid
The overall effect will be like the tread pattern of a mountain bike tyre or a 3D checker board.

This project is documented at my blog eclecti.cc/hardware/facecube-copy-real-life-with-a-kinect-and-3d-printer , but I will summarize it here.

This project is a tangent off of something cool I've been hacking on in small pieces over the last few months. I probably would not have gone down this tangent had it not been for the recent publication of Fabricate Yourself. Nothing inspires me more than when someone does something cool and then releases only a description and pictures of it. Thus, I've written FaceCube, my own open source take on automatic creation of solid models of real life objects using the libfreenect python wrapper, pygame, NumPy, MeshLab, and OpenSCAD.

The real magic comes from when you take advantage of all that OpenSCAD has to offer. Make a copy of yourself frozen in carbonite, put your face on a gear, or make paper weights shaped like your foot. This is also where the name FaceCube comes from. My original goal going into this, I think at my roommate’s suggestion, was to create ice cube trays in the shapes of people’s faces. This can be done very easily in OpenSCAD, involving just subtracting the face object from a cube.
