How to use Autodesk 123D Catch to Scan an Object

1. You need something that can spin with an object on it like a record player,  a camera and a tripod. You will also need a computer with a web browser that supports WebGL and an internet connection.

2. Make sure to take the exact number of photos specified because 123D Catch only allows you to upload up to 70 photos. Take 30 photos at a 45 degree angle of the object while spinning it. (see picture on the right)
3. Take 20 more photos at a more elevated angle while spinning the object. (see photo on the left)







4. Take 20 more photos at a low angle while spinning the object. (see picture on the right)
5. Upload the photos to Autodesk 123D Catch App.
6. Wait for Autodesk to process the photos.
7. Select and Delete any unwanted objects in the photos.
8. Then Select File>>Download as an STL.
9. Print on your 3-D printer.


Don't worry if your first try doesn't work.  Try again. In my experience,  it works 50% of the time.
Here are pictures of the completed scan:

The basics (and more!) of 3D Printing

For those of you interested in the basics of 3D printing, this video (4:16) is a nice overview by Avi Reichental, CEO of 3D Systems.  I think he says a lot of important things, but most of all: "There's always exciting opportunities and unintended consequences."  Isn't that always the truth with any new technology?


Part 2 goes into more depth with the technology, and pros and cons of each type: FDM, PolyJet, SLS, ZCorp, Multi-Jet Modeling (MJM), SLA.  I enjoy his refreshing honesty when discussing the drawbacks of each.
