3D Printing at RML

3D Printing Policy
The Roddenbery Memorial Library is happy to provide a space for its patrons to learn about and use 3D printing.

  • What is 3D Printing?
    • A process that creates solid objects from various materials based on a digital design.
    • Rather than cutting, objects are created by printing layers of material combined to produce a physical object.
    • All you need is a 3D model or .STL file created in 3D design software or from a website such as

Please read all of the policies below. Policies are subject to change at any time.
1. Patrons are welcome to submit a request to print.
2. Only one request can be submitted at a time.
3. Printing is available on a first come, first serve basis and is done by library staff only.
4. Print requests that require the printing of many components may drop in the queue position.
5. Prints are handed over AS IS. If your print requires rafts or support structures, you will be responsible for removing these. Patrons are also responsible for misprints not related to printer failure.
6. Patrons are responsible for paying for their prints regardless of whether or not they accept them.
7. The colors available may change without notice and we cannot guarantee that your selected color will be available. Please choose an alternate color for your print on the print request form.
8. Staff review and prepare all project files. No guns, gun parts, weapons of any kind, or salacious objects will be printed.
9. We will do our best to complete your model within 7-10 business days (Monday-Friday), but if demand for the printer is high, wait times may be longer.
10. Anyone under the age of 12 must be accompanied by an adult.
.10 per gram for regular colors; special PLA material such as glow in the dark, sparkles, wood look, etc. may incur additional charges. Please inquire regarding these charges prior to submitting the print job. Fees must be paid in cash when you pick up your print. NO EXCEPTIONS!

How to submit a file:
1. Files must be submitted in STL (Sterio Lithography) format. Nearly every 3D modeling program can save a file in this format. Some, like Sketchup, require a free add-on.
2. 3D printers use metric coordinates. For consistency, it is recommended that you design in millimeters and export your STL in millimeters.
3. If you are submitting a file from Thingiverse, check to see that the model has been made on a desktop 3D printer, ideally a Makerbot Replicator. Thingiverse hosts many different types of models, some of which may not be acceptable for 3D printing. For the best chances of getting a successful print, choose a model that other people have successfully printed.
4. For your first print, we highly recommended you start small.
5. The maximum dimensions are 5×5 inches.
