• The following policy, as specific to the Deerfield Public Library’s 3D Printer, establishes how this technology may be accessed and utilized by library patrons:

Print Requirements

  • Patrons can only use filament supplied by the library.  To cover the cost of filament used, 3D prints are charged at a rate of 10 cents per gram of filament used.
  • There is a minimum charge of $1.00 per 3D print.
  • No estimated print time can exceed 3.5 hours.
  • The 3D printer must be used only for lawful purposes. It  may not be utilized to create a weapon of any kind or objects that:
    • Are prohibited by local, state, or federal law.
    • Are inappropriate for the library and public environment.
    • May cause harm, be unsafe, or pose an immediate danger or threat to oneself or the well-being of other community members.
    • Are subject to a legal copyright, patent, or trademark.
  • A DPL staff member shall review each object file before it is cleared for 3D printing, and the library retains the right to refuse or deny any 3D printing request.


  • Patrons may only have one print job in the queue at any time.
  • Files are printed on a first come first served basis, and we cannot guarantee prints will be completed by any given date or time.


  • The Deerfield Public Library is not liable for injuries, property damage, or failure of function caused by objects or materials made through the utilization of our 3D printers.
  • Due to the nature of 3D printing, no file is guaranteed to print successfully, and minor flaws and imperfections can be expected, such as small cracks and warping at the bottom of the print.  The Library will not refund any prints with minor imperfections, but staff will do its best to notify patrons if a print is likely to have imperfections when they review the print file for approval.  If the final print results in large sections of the model missing (such as a missing limb of an animal statue), library staff will notify the patron of the failure and remove the charge.
  • Since 3D printing is a visual process, complete and total patron privacy is not a possibility. However, the library will not offer or provide information about a 3D print requester to third parties.
  • The Deerfield Public Library is not responsible for 3D prints that are unsuccessful on our 3D printer and will not refund the cost for filament. However, the library staff will do our best to help in completing each 3D printing job successfully.

The above policy is subject to change or amendment through the Deerfield Public Library at any point in time.
