3D Printing

3D Printing at the Library 

St. Charles Public Library strives to provide patrons access to new and emerging technologies that fuel the imagination, inspire an interest in design and help create new experiences.

The 3D printer is available to St. Charles Public Library cardholders to make three-dimensional objects in plastic using a design that is uploaded from a digital computer file. The Library has a Dremel DigiLab 3D40 3D Printer on loan from Fox.Build and a Dremel DigiLab 3D45 3D Printer.

How to Submit your Design

To submit a design for printing online click here or bring the design on a flash drive to the Computer Help Desk. You must provide name, contact information (phone or email), and your valid St. Charles Library card number.

   Printing requirements

  • The design must be submitted in .stl file format.
  • The maximum size of the 3D print object is 10” x 6” x 6.7”.

  • Only one print request per card will be accepted and printed at a time.
  • Submissions will be prepared by Library staff for printing and will be reviewed for printability and appropriateness.
  • Completion time for print jobs will vary depending on the object design and demand for the printer. The Library cannot guarantee that a print job will be ready on a specific day.
