Answer:
b. End-use application segmentation
Explanation:
Based on the information provided within the question it seems that the best business-to-business market segmentation to use in this scenario would be End-use application segmentation. This is because this market segmentation focuses on creating a product or service based on the specific details, use case, and design that the customer provides, and price is determined by this as well. Since your company can 3D print anything, then the product and price depends on what the customer wants and needs, which is why this is the best type of market segmentation.
