3D Printing

The Northbrook Public Library offers 3D printing to support learning, creativity, and exploration. Prints may be submitted in person during the Collaboratory's open hours or via email.

Prints take 1-2 weeks to complete. During the summer and holidays, the wait time may be 2-4 weeks.

Our 3D Printing Filament

We print in two types of filament due to their relative safety and low emissions: PLA and PETG.

PLA is appropriate for most items and we offer it in a variety of colors.

PETG is recommended for functional, mechanical, and outdoor parts due to its strength, flexibility, and resistance to heat and UV exposure. We offer it in black or white.

Submit a Print Request Online

Step 1: Get Your 3D Model File

To print an object, you first need a digital 3D model saved as an STL or 3MF file. You have two options:

Option A: Find a Ready-Made Design Online

Sites like thingiverse.com and printables.com have thousands of free designs that you can download. You can browse or search for specific designs.

Option B: Design Your Own

You can use design software to create your own objects. TinkerCAD.com is a fun, free online programs for beginners of any age, offering built-in tutorials.

Other software includes Blender, Sketchup, FreeCAD, OnShape, and more.

Once you’ve got your design, download the STL or 3MF file.

Step 2: Email Your Request & Filament Color

Email us at 3dprinting@northbrook.info. Be sure to attach your STL or 3MF file and include the following details:

  • Your full name
  • Your library card number
  • The desired dimensions of the final object
  • Your preferred color. Items may only be printed in one color.

Available Colors:

PLA: Black, White, Gray, Brown, Natural, Pink, Red, Orange, Yellow, Green, Blue, Purple

Available Colors:

PETG: Black, White

Step 3: Approval, Payment and Pickup

Cost Estimate: We’ll give you an estimated cost for printing your object and will only print with your approval.

Turnaround: It usually takes 1-2 weeks for us to complete your print. During the summer and holidays, wait time may be 2-4 weeks.

Pickup: We’ll email you when your print is ready. Pick up your print outside the Collaboratory. It will be in a paper bag with your last name on the cabinets in front of the Collaboratory. Prints are discarded after 30 days and any fees are your responsibility.
