1) model 1:18
- car boundary box dimensions: 5'000 * 2'000 * 1'500 [mm]
- car model boundary box dimensions: 278 * 111 * 83 [mm]
2) printed model (SLA, 0.1mm detail == HQ surface) wall Thickness - 1 mm
3) used material for print: 2.5x area of boundary box = 1'263 cm2 => 316 cm3
4) print cost: 2.78 $/cm3 => 654 EUR + exta costs (shiping, price for 3d mesh detailed model, acount in ponoko, ...)
5) resin used for final vacuum castings ~ used material for print / 2.0 = 158 cm3
6) silicon moulds for 50 pcs (mould lifetime) triple cost of resin for casting => 474 cm3 of resin (summary cost equivalent)
7) cost of casting (without vacuum casting process costs, shoping, ...), 12 EUR/dm3 (poliurethane casting resin cost, RenCast FC 52) => ~6 EUR/model
=> summary costs (+ extra) per 50 cars => 19 EUR
What could change the price:
- cost of detailed 3d model itself - 0-250 EUR
- 3d print: +/- 50% i think
- cost of shiping: ??
- cost of vacuum casting process - 2-5 EUR/car
=> price range for 50 cars (example) => 14-42 EUR/car + shiping costs + licence fee for lfs.
About comercial licence fee - it could be 24 GBP == 28 EUR.

I thing tha resonable prices could be:
=> 50 cars -> 25 EUR/car + shiping
.........=> 25 EUR for model + 5 EUR for S1 LFS licences for nice racers -> 30 EUR/model + 17 licences.
=> 100 cars -> 15 EUR/car + shiping
.........=> 15 EUR for model + 5 EUR for S1 LFS licences for nice racers -> 20 EUR/model + 35 licences.
Model 1:24 could 50% cheaper in manufacturing.
It's just for info.
