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.


Printing Policy

The Library’s 3D printer, including our 3Doodler Pens, 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 (such use may violate the terms of use of the manufacturer)
    • Obscene or otherwise inappropriate for the Library environment
    • In violation of another’s intellectual property rights. For example, the printers will not be used to reproduce a material that is subject to copyright, patent or trademark protection.
  2. Priority is given to Merrimack Public Library cardholders.
  3. The Library reserves the right to refuse any 3D printing request.
  4. At this time, there is no charge for this service.
  5. Print-on-demand objects must require less than 10 hours to print each piece. Multi-piece requests will be considered on a case-by-case basis.
  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.
  9. The Library reserves the right review all files before printing and to refuse scanning and/or producing any content at any time at the discretion of the Library Staff.
  10. Schedule and access to the 3D printer will be determined by Library Staff.
  11. This policy, adopted in January of 2016, will be reviewed every six months to allow for evaluation of the use of this technology by staff.

Approved by the MPL Board of Trustees January 19, 2016; reviewed and approved July 19, 2016.
