In this video I demonstrate how to convert a .PLY Point Cloud file into a STL file to be used for 3D Printing. Use of Meshlab and Meshmixer.

Meshlab Application: http://www.meshlab.net/
Meshmixer Application: http://www.meshmixer.com/

By the way, most 3D scanning software does what I show you here, behind the scenes. So there is a chance you'll never need to use this, but hey!... In case you do, it is here for reference.

Oh and here for reference for myself so I don't forget.

Hope this video helps! I don't know a lot about Meshlab so I hope I didn't do too terrible. ;)
