In keeping with our efforts to offer the community opportunities to learn about new and emerging technologies, the Wilmington Memorial Library has a 3 D printer available with the following guidelines for its use.

  • The Library’s 3D printer is a that can make simple three dimensional objects in plastic using a design that is uploaded from a digital file.
  • The Library’s 3D printer may not be used to make any 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 material that is subject to copyright, patent or trademark protection.
  • The Library reserves the right to refuse any 3D print request.

Design Creation

A file is obtained from a 3D Printing Object repository, such as http://www.thingiverse.com/, or by creating a design using computer-assisted design (CAD) software, such as https://tinkercad.com. All files for using the 3D printer need to be either in .stl or .obj format.

Using the 3D Printer
Patrons should register to use the 3D printer on the library’s website www.wilmlibrary.org and then check in at the main desk.  Patrons who are unfamiliar with how to use a 3D Printer will need to sign up for a Tech Help session.

There is no charge for printing at this time. However, there may be a charge for printing more complex objects that take longer than two hours. An object that will take more than two hours to print needs to be preapproved by the Technology Librarian.
