3D Printing

3D Printing

STPL has a FlashForge Dreamer 3D Printer. It is a dual extrusion printer, allowing prints in two colors.  Patrons may attend our 30-minute training session for hands-on training with the 3D printer to submit files to be printed.

What is 3D Printing?

3D Printing is the process of making three-dimensional object from a digital file. The object is created by laying down successive layers of plastic material on top of each other until the print is created

Submitting A Design to Print

A signed copy of the 3D Printing Agreement must be on file prior to any designs being printed.
3D Printing Agreement

• Use of the 3D Printer is at the discretion of library staff. The library reserves the right to deny use of the equipment.
• The 3D printer may only be used by STPL library cardholders.
• The cost for printing is $0.20 per meter 
of filament.
• The patron must accept the estimated cost for the print job prior to the design being printed.
• Design files must be submitted 
as an .stl files. We cannot print a file over 5 hours long. The design must be able to fit on the 3D printer’s platform (8″wide x 5″deep x 5″high).
• The library will do its best to have a design printed in a timely manner does not guarantee that a design will be printed by a certain date.
• The library does not guarantee a successful print. Unless the print fails to finish, the cost of the completed print, regardless of quality, will still be charged.
• If a 0-2 hour print fails, it may be attempted only one more time without charge. If a 3-5 hour print fails, any additional attempts will be charged.
• Items that are not picked up after a month will 
become the property of the Surrey Township Public Library. Items must be picked up by the individual who printed them.
• A charge in the amount of the print’s cost will be added to the patron’s record for any unclaimed items.

If you would like to submit a design to print, you must first complete a short training session with a member of the library staff.  Reserve


How long does it take to print a design?

Printing times vary widely depending on the design. If an object has many layers or a complicated structure it can take several hours to print. Smaller, simpler designs can print in as little as 5-10 minutes.

How do I create or find a design to print?

You can use one of 2 methods: Download or Create.
• Download: Find free, copyright-free designs online at sites like www.thingiverse.com
• Create: Use software like Tinkercad or Google SketchUp to create your own 3D designs.

How do I submit a design to print?

To submit a design for printing, bring in your .stl file on a flash drive or email your .stl file to director@stpl.org and one of the library staff will follow up with you with an estimated cost for printing. Before we will print your design you must have completed the training session and accept the estimated printing cost.

How long will it take to get my design printed?

Usually, the process of 3D printing requires troubleshooting, whether that be from errors with the design or repair of the printer, which is why the library cannot guarantee that a design will be printed by a certain date. We will do our best to have the design printed in a timely manner.

What type of filament is available?

3D printing is available with PLA filament. PLA (Poly-lactic Acid) is biodegradable plastic. It is made from renewable raw materials such as cornstarch. There is currently a vast array of filament colors to choose from, please indicate your color choice when submitting a file for printing.

Are there any other design rules?

3D printing does not do well with “overhangs.” Each layer of a 3D model needs a base layer below it. The print is more likely to fail if part of the design is hanging out in space. Breakaway supports can be added to any overhangs, but the edges might not be as smooth.

Keep in mind is that PLA has a very low Glass Transition Temperature (approx 60 degrees Celsius), which means that it will turn from a hard plastic to a soft rubbery material in high temperatures.

How many designs can I have printed?

You may submit one file per week. Keep in mind that there may be other print jobs ahead of yours and that the library cannot guarantee that the design will be printed by a certain date.  Students under the age of 18 may print one item using less than 5 meters of filament per month free of charge.
