Is this a viable part for 3D printing???

[TonyE]

Hello all,
Firstly, I am very new to 3D printing - never done it before! However, I do own laser cutters, CNC machines and do 3D modeling and CAM work so am fairly savvy in these technology fields.

I am considering the use of 3D printing to print parts as shown in the attachment. I am looking at carbon reinforced Nylon as the filament source. The parts are generally 2 to 2.5mm thick (high), and the webs are 2mm on the edges and 3 to 4mm wide internal to the structure. Lengths vary up to 400 or so mm long.

Are parts like this viable for 3D printing?
What would be the major constraints for such fragile looking parts?

Thanks, Tony.
