3D Printing

intro banner

OPL has new 3D printers!

Book a 3D Printing appointment with your local branch!

Print your files at any Oakville Public Library branch, now equipped with Ultimaker 2+ Connect 3D printers.

With a 3D printer you can create 3D objects like toys, jewelry, replacement parts and so much more. In order to print you first need a 3D model which you can source for free on databases like Thingiverse or design your own using free programs such as Tinkercad or Blender. Design and prepare your files from home or book a library computer. 

How it Works

In order to use the 3D printers at the library you must:

  1. Be an Oakville Public Library cardholder age 13+,  or otherwise accompanied by an adult
  2. Complete our 3D Printing Certification
  3. Download or design a 3D model and save as an STL or OBJ format*
  4. Slice your file using Cura in branch or at home*
  5. Save your sliced G-Code file to a USB key for use on printer
  6. Reserve a 3D printer (3 hour time slots available)
  7. Check in at the Service Desk when you arrive

* If you require access to a library computer to download a model or use Cura, please reserve a computer

Print Cost 

Print costs are calculated in 10 minute increments as follows: 

00-10 minutes 

10-20 minutes 

20-30 minutes 

30-40 minutes 

40-50 minutes 

50-60 minutes 







The average print job takes about 1 to 3 hours.

Our Machine

The Ultimaker 2+ Connect uses Fused Filament Fabrication (FFF) print technology. The printer feeds filament through a heated nozzle, similar to a hot glue gun, applying one layer at a time. The process is repeated until the object is fully formed. 

Technical Specs

  • Print head: Single extrusion (180-220 °C) 

  • Build plate: Heated glass build plate (20 - 110 °C) 

  • Print Area (XYZ): 223 x 220 x 205 mm (8.7 x 8.6 x 8 inches) 

  • Connectivity: USB 

  • Slicing Software: Ultimaker Cura 


Every OPL branch offers white, black and red PLA (Polylactic Acid). White is the standard but the filament can be changed upon request and based on available stock. 

PLA is a biodegradable thermoplastic derived from cornstarch. It is sandable and paintable! 

Cura Slicing Software 

Cura slicing software is available in branch, but is also available for free to download onto your personal computer. This software takes a 3D model (STL/OBJ) and slices it into thin layers which is then saved as a G-Code file.

G-Code is essentially a list of instructions for the 3D printer to follow such as how hot the extruder should get, how fast it should move, the thickness of layers, ect. 

Once you’ve determined these settings in Cura you must save the G-Code to a USB key for use at the library. 


When 3D printing at the library you cannot print:

  • weapons
  • sexually explicit material
  • anything that violates the libraries policies
  • objects that infringe upon intellectual property rights


OPL is not responsible for any personal injury, damages, or harm that may result in use of the equipment.
