3d Scanning at the Museum of Art and Design with Shapeways using a Microsoft Kinect and Skanect software.

Step 1: Setup

What you will need:

-computer
preferably a desktop as files are large

-Skanect software
(http://skanect.manctl.com/)

-Microsoft Kinect
This device reads color with its camera and reads depth with the infrared sensor.

-Lights
Lighting is very important in order to get an even colored scan

-spinning platform (optional)
This allows the subject to rotate making scanning much easier

Step 2: Software settings

Open Skanect / Go to NEW / Make sure your settings match those in the picture

(for a child you may want to make the bounding box a bit smaller)

Press START

Step 3: Workspace

A screen will come up showing the bounding box in the middle. The infrared and video images are on the right.

Step 4: Lovely Assistant

Have your lovely assistant step onto the platform. Be careful! It spins! Make sure the lighting is consistent on your subject.

Step 5: Record

Hold your Kinect up level with the subject's waist a few steps feet back from the platform. Press RECORD. The Kinect will begin recorded the depth (red) and the color (green).

Step 6: Spin Around

Once you have done one full sweep of your subject head to toe, press the pedal to make the platform spin. As your subject is in motion slowly move the Kinect in an up and down motion making sure to get the top of the head all the way to the bottom of the platform as they rotate.

If you do not have a rotating platform have no fear. You can walk around your model or use any manual spinning base of your choice.

Step 7: Lining it up

As you are scanning be sure that you are getting a high frame rate around 18-24 frames. If you get below 18 you have to move your Kinect faster. You can monitor this by looking at the white numbers at the bottom of the screen. These numbers can also aid as a way of keeping your subject in alignment. If you keep the numbers in the center of your subject as you scan head to toe you can be sure your scan will be straight.

Step 8: Cleaning up your scan

Once your subject has done a full rotation press the RECORD button in the top left corner again to stop the scan. Now that you have a full body scan you have to do some post processing to get it ready to print. First is making it watertight. Go to the WATERTIGHT option. Choose smoothing LOW and press RUN.

Now your scan will have color. But it may not be straight or have a flat base. Now we have to use the MOVE & CROP tools. Use the SLIDE BARS to adjust the X, Y, and Z axis of your scan to make it flat and straight. Make sure your base is parallel with the X Y plane as cropping will cut off anything below it to make a flat base. Type in the name of your file in the TEXT BOX. Press CROP TO GROUND.

Step 9: Exporting Model

How to 3D scan with Skanect
To export it to your computer go to SHARE and the export menu will open with a LOCAL option. Under LOCAL go to EXPORT MODEL and use the setting seen in the picture to export for printing. It is important to chooseVRML as the file type. This file type reads both shape and color. Click EXPORT and you are done! Now you can use that file to upload to a 3D printer of your choice.


Step 10: 3D Printed Selfie

If you wish to 3D print this model I suggest using SHAPEWAYS.COM and uploading it to be printed in FULL COLOR SANDSTONE.
