3D Printer Policy

The Caroline County Public Library’s 3D printers are available to the public for educational purposes and usage in the library makerspace to make 3D objects in PLA, or PETG plastic using computer aided design tools.

  1. The 3D printer may be used for lawful purposes only. Customers will not be permitted to use the printer to create objects that are:
    • Prohibited by local, state or federal law.
    • Unsafe, harmful, dangerous or that may pose an immediate threat to the well-being of others; for example, guns, knives or other possibly lethal weapons.
    • Obscene or otherwise inappropriate items for the library environment.
  2. The Caroline County Public Library reserves the right to refuse any 3D print request.
  3. Small part 3D printing tangential to library programming, educational and hobbyist purposes can be conducted at no cost. For projects in excess of 20 grams or for prints for explicitly commercial purposes a fee will be assessed. This fee varies based on material costs and print settings and will be calculated by the printing software at the time of print. This fee may be waived at the discretion of the Executive Director or the IT manager. Filament donation may be accepted in lieu of payment at the discretion of the Executive Director or the IT manager.
  4. Items printed from the 3D printers that are not picked up within seven days will become the property of the Library.
  5. Customers may only use the printer alongside designated library staff or volunteer coaches. Use of the 3D printer is at the discretion of the designated library staff.
  6. Supervision of the use of the 3D printer by library staff does not constitute knowledge or acknowledgment of any unapparent final use of the 3D product and the library specifically disclaims any knowledge thereof.


The Library is not responsible for any object created with use of the 3D printer, including any harm or injury incurred as a result of any usage of the 3D printer or the object printed.
