Abstract 3D printing, which is synonymous with the additive manufacturing is gaining popularity, which leads to emergence of 3D printing platforms. The pricing strategies for such platforms are quite complicated, since different kinds of products/services could be provided on the same platform at the same time. We explore the optimal pricing strategy for a 3D printing platform that sells standard and customized products, taking products' differentiation into account, where the platform and designer seek to maximize their profits, while the customer wishes to maximize their utility gained from the product purchase. In the basic model, we derive the platform's optimal prices when the platform allows the designer to add a mark-up for the standard product. We find that the standard product's final price increases with its own quality and decreases with the customized product's quality. When labour cost is low, the customized product's final price increases with its own quality and decreases with the standard product's quality. We also find that the designer's optimal mark-up for the standard product increases with the printing cost of the standard product and quality of the customized product, and decreases with the interaction cost, printing cost of the customized product, and quality of the standard product. We compare the platform's profit in the case of “partial pricing power”, in which the platform allows the designer to add a mark-up, with that in the case of “full pricing power”, in which the platform sets the final price of the standard product and charges a commission fee as its revenue. We find that if the difference in the quality between the standard and customized products is high, then the strategy of charging a commission fee at a rate of more than 25% is more profitable than the strategy of allowing the designer to add a mark-up to the reservation price.

如何为 3D 打印产品定价？3D 打印平台的定价策略

摘要 与增材制造同义的 3D 打印越来越受欢迎，这导致了 3D 打印平台的出现。此类平台的定价策略相当复杂，因为可以在同一平台上同时提供不同种类的产品/服务。我们探索销售标准和定制产品的 3D 打印平台的最优定价策略，考虑到产品的差异化，平台和设计师寻求利润最大化，而客户希望从产品购买中获得最大效用。在基本模型中，当平台允许设计师为标准产品添加加价时，我们推导出平台的最优价格。我们发现标准产品' 最终价格随其自身质量而上升，随定制产品的质量而下降。当人工成本较低时，定制产品的最终价格随其自身质量而上升，随标准产品的质量而下降。我们还发现，设计师对标准产品的最优标记随着标准产品印刷成本和定制产品质量的增加而增加，随着交互成本、定制产品印刷成本和标准产品质量的增加而降低。 . 我们比较了在“部分定价权”情况下平台的利润，其中平台允许设计者加价，以及在“完全定价权”情况下，平台设定最终价格。标准产品，并收取佣金作为其收入。
