Looking in short time for a good scanner I did arrived to consider David Laser Scaner 3.

Appear to be a good product, but appear some does simply purchase the sw and assemble by himself the various components: camera, projector, rail, calibration.

So I'm vary about spending the thousand $ for something I can build from myself with COTS components...or I did under evaluate the effort needed to select, assemble and calibrate the whole ting? Also self assembling it's a real saver, considering a good projector will cost about $800 and a DSLR camera+lens also?

I.e. there are specific needs for the projector and the camera? There are any assembly guide?
