I copied my tank model database into Microsoft Excel for the purpose of calculating costs of making these models. The material cost has already been established, but the print time and clean-up time are just guesses for now. Most of these values will be very similar, because of the similar size and shape of heavy tank models. As you can see, given my current estimates, the cost is going to be slightly higher than my previous pricing at Shapeways, but less than half the new Shapeways prices. The only parts of this spreadsheet that are permanent are the model volume and material cost. The current time cost rate of $0.42 per minute is derived from my normal labour rate of $25.00 per hour. Shipping is going to be an entirely separate cost, and just as before, ordering a large number of models at once is most cost-effective for collectors and wargamers alike.
