Our 3D Printer

The library is home to one Ultimaker S3 3D printer, which was purchased with funds generously donated by the Friends of the Merrimack Public Library. Our new printer was dedicated June 30, 2020.


3D Printing Policy

The library’s 3D printing tools are available to make three-dimensional objects in plastic using a design that the patron has provided as a digital computer file. 

  1. The library’s 3D printers may be used for lawful purposes only. The public will not be permitted to use the library’s 3D printers to create material that is:
    • Prohibited by local, state, or federal law;
    • Unsafe, harmful, dangerous, or poses an immediate threat to the well-being of others;
    • Obscene or otherwise inappropriate for the library environment;
    • Subject to copyright, patent, or trademark protection or otherwise in violation of another's intellectual property rights.
  2. Priority is given to Merrimack Public Library cardholders.
  3. The library reserves the right to review all files before printing and to refuse any 3D printing request at any time for any reason, at the discretion of library staff.
  4. While there is currently no charge to have items 3D printed, pricing for 3D-printed items is subject to change. Changes in pricing for 3D-printed items will be reflected in this policy and/or on the library's website. It is the responsibility of the patron to review the policy or the library's website for current pricing information.
  5. 3D-printed objects must require less than 10 hours to print each piece. Multi-piece requests and those that take more than 10 hours to complete will be considered on a case-by-case basis. The library reserves the right to alter the size of any prints submitted for the purposes of completing the print within the 10-hour limit.
  6. The library is not responsible for any damage, loss, or security data arising from the use of its computers or network, nor for the functionality or quality of content produced on the 3D printer.
  7. 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.
  8. Only designated library staff and volunteers will have hands-on access to the 3D printer. The schedule of operation and items printed on the 3D printer will be determined by library staff.
