Frequently Asked Questions
Who can print?
Printing is available to everyone.
Printing is free for all users.
The length of the print process is dependent upon the size and complexity of the object.
The Polar 3D printer can only print in one color. Print jobs are completed using the color that is currently loaded in the machine.
What is an extruder?
The extruder is the silver nozzle where the filament (plastic) comes out.
What is the build plate?
Objects may be printed with bumps, holes, scratches, or not at all. Remember 3D printing is an experiment and objects may not print as you expect them to.
If you are printing an object for class, please let a library staff member know a few days in advance so the printer can be reserved for a specific day and time.
Will you print it for me?
EGSC Library staff members will assist you to the best of their ability, but they will not print objects for you.
The Polar 3D printer is capable of printing objects with a diameter of 8 inches (20.32 cm) and a height of 6 inches (15.2 cm). When printing please keep in mind print time and filament use. Any objects still printing when the library closes can be picked up the next business day.
What are some examples of practical uses for 3D printing?
3D prints can be found useful in numerous applications, such as prototypes for entrepreneurs, architectural models for class projects and for any other low-volume, custom-prototype needs. Here are some examples of practice use in an educational environment:
Common Printing Issues
Object doesn't Stick to the Build Plate (Incomplete Print)
If your object unsticks from the build plate mid-print, you need to start the printing process over.
Stop the printer using the options on the Printer page. You will need to reset the print job, clear the build plate, reapply a coating of hair spray, let it dry, and try printing the object again.
Difficulty Removing Object from Build Plate
Projects with a large base (phone cases for example) or fragile elements are the most difficult to remove from the glass build plate. Gently lift one corner to pry the object off; grabbing, twisting, and turning works for most builds. If this does not work, try using a solid flat object to spatula the object off. If you need assistance, please ask a Library Staff member.
Filament build up
With smaller objects, the filament may not have time to dry before the next layer is added. This can cause the filament to build up in one place and create a pileup. If this occurs, start the printing process over.
Elephant Foot (too wide base)
Sometimes the base (first layer) of the model is wider than it should be. It will affect the final print quality, but will not affect the printing process.
Shifting Layers / Leaning
This is something that affects the final print quality, but will not affect the printing process.
Stringing / Oozing
Strings or stray hairs are sometimes left behind as the extruder moves from one space to the next. They can be cut away after printing is complete.
Extruder (Nozzle) is Clogged / Stops Extruding Mid-Print
If the nozzle is clogged and will not extrude filament or it stops extruding filament mid-print, stop the print job and alert a staff member immediately. Do not attempt to clear the debris.
