Printing car parts?

[curious aardvark]

Not necessarily.

Just built myself a delta from a kit.
The kits are $199 - print volume is 8 inches by 12.
Now I wouldn't ordinarily recommend it to a first timer. But sounds like you're used to making stuff and I've covered all the niggles in my build thread.
So you can get the few extra bits beforehand.

Still only 8 by 12.
However - all it needs to extend the build height are longer belts - pretty cheap and longer vertical struts, also pretty cheap. Longer filament feed tube and some wire to patch longer wires on the end stops and hot end wires.

he3d do a kit that's 280mm by 600 for another $300 bucks.
I figure I can extend mine to 200 x 600 for about another $80
Theoretically there is no actual limit to the height you could extend it to.
You just need long enough belts, enough belt tensioners (dirt cheap) and longer wires for the end stops, extruder and hot end.
However as you are dealing with a bowden setup (filament is pushed through a long tube) I'd personally probably only go as far as the 600mm build height.

That said, you can use a fl3xidrive which puts a super lightweight direct-drive extruder directly on top of the extruder and eliminates the filament tube issue.

The kit from he3d is $559 for 280mm x 600 (well 570 with the hotbed - which I would recommend). http://www.reprapmall.com/index.php?...product_id=117

Beat that :-)

Oh yeah - under no circumstances feel tempted to get the ciclops scanner. Absolute junk, does not work, will not scan anything, ever.
