Start with a MasterModel

A MasterModel is a script that can generate 3d models of a specific type. MasterModels are extremely flexible, and are created by authors with some 3d experience. You can find MasterModels by searching our catalog, or by using a link a friend has shared.

Each MasterModel has a number of inputs, called 'parameters', that you can control to create the output you want. Using the web-based interface, you can preview the 3d design as you change the parameters to suit your needs. You don't need to know anything about 3d CAD or CAD software to make these adjustments-- the interface is fast and easy.

Once you are happy with your design, it time to print it. With one click, you can send your design to one of our 3d printing partners, or download it locally to print yourself. We support tons of formats, including industry-standard STL, as well as industry-leading AMF and STEP for higher quality prints.
