3D Printer

Printer Policy

Purpose and Statements

3D printing is a courtesy service provided to all members of the public who visit TPL, and not limited specifically to patrons or program attendees.

This policy explains the terms and conditions for using the 3D printing service at the library. Before items can be printed, member must agree to these terms and conditions, and agree not to hold Terrace Public Library responsible for any consequences arising from misuse of the service.

These terms and conditions may be changed later. Revisions to this policy will be noted on the library website.

Requirements

Anyone can use the 3D Printer, once they have spoken directly to a TPL staff member. Requests can be given either in-person or via email at programs@terracelibrary.ca.

As of April 2026, the Library has two printers:

Submissions will generally be printed on a first-come, first-served basis in the order they are approved.

Modifications

Members of the public are responsible for making any modifications to submitted designs — if there is a need to change their design, they must cancel their pending request by email, make any changes themselves, and resubmit. Modifications cannot be made once an item has been printed.

Examples of design modifications include:

Guarantees

Staff will attempt to ensure submissions are printed successfully.

However, Terrace Public Library does not guarantee:

Limitations

The following limitations apply to all submitted jobs:

Inappropriate Submissions

As the 3D printer is a courtesy service, TPL reserves the right to refuse to print designs on any ground, but the following items will not be printed for any reason:

Permissions

Users must accept all responsibility for ensuring that their submission does not violate any of the following regulations:

Fees

The cost of material used is $0.50 per gram. This cost is subject to change.

Print Pickup

Staff will contact patrons via email (or phone) when items are ready, and payment for items will occur when patrons arrive for pickup. Patrons can pay using cash or debit payment methods at the library desk for items before release.

Troubleshooting

Under-Extrusion

This happens when your print isn't getting enough material through the nozzle. Missing layers, thin layers, random holes, when it looks really bad your extrusion is likely to blame.

The spools are clear? The nozzles are set to the right size? The layer height is good? If you're confident in your settings, but the job still doesn't look right, it's time to check the material itself!

If your material is too cold, it will increase pressure in the nozzle and mess up the layers. If the material is too hot, you might clog or damage the nozzle. Every filament has recommended nozzle speed and nozzle temperature. Usually, when you lower the temperature, you also need to lower the speed. Please ask staff for help if you're not sure!


Pillowing

When the top surface shows little pockmarks, we call it pillowing. This is always a result of having your shell layer set too thin.

The outer shell of your model should have a "Wall Thickness" that's roughly 6x higher than the layer height you've chosen. If you do that, it'll be nice and thick!

It's also possible that the printer's fan is not working. If that's the case, let us know!


Stringing

These small strands of plastic happen when the nozzle travels and drips. This is almost always because the temperature is set too high for the material in question. Slowing down the nozzle speed can also help.

Never try to print multiple items at once. It will string between the two, as it will insist on switching for every single layer!


Warping

This happens when the material hardens. As it dries, it tends to shrink. When it shrinks, it lifts the corners and edges away from the build plate.

The best thing to do is to help the build plate stay warm. Use Cura to turn up the heat on the build plate and keep the printer door closed!

If that doesn't help, you should try to make a much thicker bottom layer. The easiest way to do this is to add a Brim or a Raft. The Brim will print a thicker layer that peels off when the job is complete. The Raft is the most powerful option that creates a thick lattice, a scaffold for your entire project to sit upon.

Even if it doesn't look like it, your project might need supports turned on. Check for any surfaces that need supports!
