Producing a 18" L x 7" W x 6.7" H (457.20mm L x 177.80mm W x 170.18mm H) with Frosted Ultra Detail plastic as a single part is not possible, since the maximum allowed dimensions for a single FUD-made part are 284mm L x 184mm W x 203mm H. Since this "1/10 scale body shell" sounds like an RC model, I would say that producing the part with FUD (even IF you could) would not be a wise decision, because FUD is very delicate, quite fragile, requires to be carefull while handling and is not the best choice for such use. The FUD plastic is the ideal material for replicating amazing details and tiny miniatures, but you cannot rely on strength for such a big RC model that requires to sustain structural stress and possible RC model car crashes on walls or roll overs. That is why companies build their body shells with lexan which is cheaper than dirt and durable. Same time, considering the high price, producing the part with FUD (even IF you possibly could) would require too much USD and IMHO it would not worth the cost, while there are other available choices out there.
