Hi there! I want to build an exact clone of shapeways dot com clone for my country. The homepage layout i think it'll be the same.
The core feature of this site is the possibility for the users to upload their 3d model, and sell to the community.
Every of each model when sold, it's produced on some material like plastics, metals, or ceramics, that has costs. For the final selling costs the platform take the volume of the 3d model, expressed in cm3, and multiply for the material cost for determine the production cost (see the materials table below). This value is the base where users can apply there commission fee for each sale.
Most important is the upload model method, users must be registered, then the can access and upload a model by the form.
In back-end an admin approve the model. As you can see in the attached file, in the users dashboard, there's a table in which users can change their commissions.
Users must have a dashboard where they can see the gallery of their product, adjust the commission fees, change title, description, tags, and it decides if a model have to be public and selling. (see image edit_mode_user).
On a product page, there is a 3D viewer, it can be dome by a free scaript for blender called 3dnp, so it must be included on the products images slideshow exactly like shape ways.
I invite you to try yourself the shapeways platform to understand how it works. It's quite simple.
