The pace of innovation in the 3D Printing world is dizzying. Now you can have a 3D copy machine in the convenience of your own home. What will you copy? Buildings? Statues? Your children? Ian Johnson did a great job of scanning his Hawaiian Menehune, converting it to a 3D model with 123DCatch, and printing it on his Solidoodle 3D Printer. He says, “Using 123D Catch is very easy. Basically, choose the photos to upload, push a button, and then wait for the project to be finished.” Mind blowing.
