Design creation:

  • The 3D printer can be used with basic knowledge of Computer Assisted Drawing (CAD). Creating a new design requires an advanced knowledge of 3D modeling software products. Video tutorials that accompany CAD programs can be of assistance.
  • Try Tinkercad for beginner-friendly CAD software.
  • Any 3D drafting software may be used to create a design as long as the file can be saved in .stl file format.
  • Ready-made digital designs are also available from various websites like Thingiverse, 3D Warehouse, and Bld3r
