3D-Scanning Techniques

An invaluable aid to 3D-print designers is a 3D scanner. Having the capability to scan objects around you can be extremely useful. Scanned objects can be reversed engineered, modified for artistic purposes, or used as placeholders for other geometry.

There are many 3D scanners on the market today, and while many of those options are inexpensive, even the most affordable 3D scanner can be out of the price range of the average consumer who is starting to explore 3D printing for the first time. For designers on a budget there is one 3D-scanning method that is completely free, which will allow anyone to transform ...
