Public Use of the 3D Printer

RPL is making our MakerBot Replicator 3D printer available for public use at a nominal fee. Library patrons can submit projects to be printed. RPL Volunteers will work with patrons to help them prepare their project for printing. The volunteers will also be the only people who will operate the printer.

To learn more about the specific features of the MakerBot and how you can schedule a print job, please read Information about RPL’s 3D Printer.

Patrons wishing to have an item printed must read, sign, and bring in the 3D Printer Acceptable Use Policy before scheduling a print job. There are no exceptions to this process.


The 3D Printer Project Request Form outlines the process for working with the volunteer and explains the requirement for preparing a print job. The form can be filled out online or printed to bring in when meeting with the volunteer.

3D Printer Project Request

The Rockville Library provides an opportunity for their patrons to submit projects to be printed using the MakerBot Replicator 3D Printer. Digital files can be self-created or downloaded from a web-based, design-sharing site.

Patrons who have read and signed the Acceptable Use Policy (AUP) for the 3D Printer are eligible to submit a project request. The request can be submitted online using the form below or printed from the link below and returned to RPL.  Once the form is submitted a Library volunteer will contact you to schedule an appointment to review the request and to ensure that the project adheres to the Library’s AUP.

Before you meet with the volunteer, put your project on a flash drive. At the library, the volunteer will download the project from the flash drive onto the build plate of the MakerBot. At this time, the volunteer will estimate the amount of time needed to print it and give a non-binding estimate of the price of the print. The patron will have a chance to review the size, weight, time duration and potential cost to make any changes. Larger projects may have to be scheduled to run on a day when the Library is open for a full day.

Once the patron has agreed to the finalized the design, a print time will be scheduled. The patron will be notified when the object is complete and how much the build will cost. Patrons have seven days after notification to pick up their projects. Patrons who do not pick up their projects will have the cost billed to their library record.
