Many of you have been asking for more transparency on how we price our materials. We cannot provide the exact formula for competitive reasons, but our team has compiled the following guide that outlines the different factors used to price each material and will list it in this thread. Hopefully this will help you best design for different materials to help keep your costs lower. We have updated these components on the Design Guidelines tab for each Material we offer on our website in the pricing section. For example, click on the Design Guidelines tab in our Fine Detail Plastic page and scroll down to the Pricing section. As we make tweaks to our pricing algorithm in the future, we will update those Design Guidelines, and will deprecate this forum post so there is only one source of truth. This forum post reflects accurate pricing components as of today. I'm going to keep this post unlocked for the time being, but please keep all comments in this thread on topic or they will be removed: Questions about how to interpret this algorithm are OK. Complaints about shapeways pricing policies are not appropriate for this thread and should be sent to firstname.lastname@example.org instead. Questions about a specific model's pricing are not appropriate for this thread and should be emailed to email@example.com instead.
