3D Printer Resources
Libraries Lend out 3D printers to make PPE
The Library believes in integrating new technologies into programs and everyday life to the best of our ability. The 3D Printer is our newest technology so, we have put together this resource page for your interest and to better prepare you on your way to have an object printed!
3D Printer Info
The Library owns and operates model AFP-1728 built by S-Squared 3D Printers. Once it has been determined that the file does not violate the Library’s Policy on 3D Printing, your project will be included in a queue to be printed. To learn more about 3D printing and design, continue to read below or view our Events Calendar to register for a program (offered periodically).
If you are interested in having a 3D design printed, please review the resources below and then click on the link at the bottom to submit your design.
Preparing your File
1. Creating or editing a model for the 3D Printer
You can design your object in any 3D modeling software of your choosing. Below is a list of Free 3D modeling software and open source model websites.
Free 3D Modeling Software
Recommended! Tinkercad – a browser-based 3D design platform, now part of Autodesk (free version available).
OpenSCAD – free software for creating solid 3D CAD models. Useful for creating models of machine parts.
List of additional free software packages from 3ders.com.
Free Open Source 3D Model Websites
You can search for pre-existing models on the Internet to print as they are, or to modify using 3D modeling software.
Recommended! Thingiverse – MakerBot’s searchable design library community.
3D Warehouse – Sketchup’s searchable design library.
Instructables – from the 123D community.

2. Formatting your File for the 3D Printer
Export your model as a stereolithography file, with an STL extension (.stl).
Maximum size is 304.8 x 304.8 x 304.8 mm (12 x 12 x 12 in).
Please note that larger jobs will cost more and will require more time to print. You can specify a different quality level by making a note under “Description & Special Requests” on the 3D Printed Object Request Form.
Please note that multiple parts may cause a delay in printing your object. If your model includes multiple parts, make each as a separate STL file. You can submit each model as part of the same print request.
Make a solid design
The surface of your 3D model must be watertight. This means all faces of the object must construct one or more closed volume entities. Gaps or holes in the model will cause it to print incorrectly.
See Rhino’s How do I Make a Solid Model.
Check your design for holes, gaps, or other problems before submission. Numerous third party tools can help you fix geometry problems, including:
- NetFabb – provides a cloud base service and free downloadable software that can check you files
- MeshLab – open source software for checking files
Shapeways offers a tutorial for fixing and repairing 3D models using these services.
Once your model is ready to go, make a 3D printing request and upload your STL file. A staff member from the Library will contact you within five business days with an estimate for the total cost (80¢ per ounce of filament used) and turnaround time and also let you know if there are any problems with the file.
