3D printer and CNC routers

[EddyCurrent]

There are quite a few people who visit the CamBam forum; http://www.cambam.co.uk/forum/index.php and present items in 3D for milling. They have difficulty in seeing that only 2.5D is required and a flat dxf file is therefore more appropriate.
I also think there is a lack of understanding/experience regarding properties of materials and fabrication methods whereby complex objects can be built up from simple parts rather than trying to make it all out of one part.

For me, 3D printing is nowhere near as demanding as cnc routing, other than some CAD work not very much crosses over in my view, maybe just bad habits

Well I own a bridgeport mill and a colchester student lathe

So i would say i have a reasonably good idea of what can and cannot be done with a traditional machine.

Now what do you mean by 2.5D?

I was talking about the 3D printing people moving to cnc.
