You need to prepare a model file first, during slicing Luban can translate the geometric information in the model file into instruction information that the 3D printer can read and understand.
For more information about how slicing works, read our Academy article: Slicing and G Code: The Bridge Between 3D Model and 3D Printer.
Here are a few options for preparing the model file for 3D printing:
Luban Library
Use provided models in 3D Printing Library.
Download:
Download free and high-quality 3D models online: Recommended 3D printing model website.
Design:
Design 3D models with 3D modeling software, like SketchUp and Fusion 360.
3D Scan:
3D-scan models of various physical objects with a 3D scanner.
