As we know, CNC machining can produce kinds of metal and plastic parts with a wide range of available materials. However, it is difficult to decide the best material for your project. Based on 2fprototypes' CNC material list, we conclude the basic material property in the following table. For some common materials, we have attached our product cases for your reference.  We believe you will benefit for your next project.
