How to Use the MakerSpace Facilities and Services: 3D Printers

  1. There is no charge to use 3D printers provided by the MakerSpace. Users are responsible for the costs of 3D printing filament.
  2. Users are responsible for any damage to the furniture and equipment in the MakerSpace.
  3. Unless otherwise approved by the University Librarian, the 3D printers are used by eligible users for educational and non-commercial purposes ONLY.
  4. Users should comply with copyright, patent, and other intellectual policy regulations, which do include specific exceptions for fair use. CUHK Library staff reserves the right to refuse any usage request. 
  5. For opening the UP mini 2 3D printer service, the user will only use the filament that MakerSpace provided.  There is no guarantee of the color of the filament and the result of the 3D print.
