Yes, I was checking the FAQ section and they state that clearly:
"How large of a part can you make?
Parts must fit within a 8in. x 8in. x 10in. volume, although your 3D models can be made in sections and then glued together. You would need to submit the 3D file for each piece for us to provide a price quote"
I guess is better suited for organic shapes, where the resulting porosity does not hurt that much. This system cannot produce fine details (as explained in the FAQ), and unless heavily primed, It does not look like it can get scribed panel lines. At 10 in. you coud get approximately a 1:60 VF-1, which limits larger planes to 1:72 (in standard scale). Larger would mean several sub assemblies... Mmmm too expensive for me (but still interested, which is why I check this thread each 2 or three days!).
Regds,
