3D printing at Mississippi Mills Public Library!

Want to learn how to use our 3D printer? Email or phone 613-256-1037 for more details.

Our Prusa I3 MK3S​ is available for printing small-scale 3D printing projects.

Mandatory 3D Printer Training is required before using the library printer.

Please note that use of the 3D printer requires a design file to be saved to an SD card. The SD Card must be smaller than 32GB and formatted in FAT32. The Prusas are able to print from both .stl files and G code.

You may design a 3D model at home, or find a ready-made design online, and save it to your own SD card to bring with you, or use one of the sample print jobs on the SD card we have provided.

Only MMPL-provided filament may be used in the 3D printers to prevent damage to the machine.

Frequently Asked Questions

What material does the printer work with?

Our printers “print” (extrude) PLA plastic, a corn-based product. We usually have several colours of this plastic available.

What is the maximum size of object I can print at the library?

The object or part thereof must fit within the confines of the build area in the printer, with a maximum build volume of 25X21X21 cm (9.84″X8.3″X8.3″), and the object must be printed within your appointment time.
