I saw an awesome article on wired. I was wondering if anyone has considered mounting a webcam next to the print head and using it as a 3D scanner. Maybe enabling adding features to premade objects. Scan in the object, manipulate it in our design software, add a feature and then print this feature onto the object.
It might work better to mount a laser line generator to a moving access and use a fixed camera to triangulate 3d data.
The best idea I have heard makes a lot of use of the exsisting hardware required for a reprap. A pin probe is placed on a pressure sensitive sensor. The probe is moved around in xy and moved down in z until the sensor detects an object.
Both of those are built in a way that doesn't play along with Wine, though, which is a bit of a bummer.
Things poorly imaged from one angle (as can be seen in their example) have holes. multiple scans could fill this area. Is there any way to merge multiple scans of this (or should I write the software for that)?
