    1. What do I need to do to get my file printed?
You will need to submit a 3D Printer Request Form and a design. Designs can either be submitted on a flash drive or created on a library computer.

      2.  Are there limitations to my design?
-The file must be submitted in a .stl, .obj, .dae, .3mf, .3ds, or .amf format file and be no larger than 25mg.
-Object cannot be larger than 10″ wide x 6″ deep x 6.7″ tall.
-A maximum of 3 hours will be allowed for each print job.

      3. What can’t I print?
Anything that is:
-Prohibited by local, state or federal law.
-In violation of items not permitted in the library such as firearms or other weapons
-Unsafe, harmful, dangerous or poses an immediate threat to the well-being of others.
-Obscene or otherwise inappropriate for the library environment.
-In violation of another’s intellectual property rights. For example, the printer will not be used to reproduce material that is subject to copyright, patent or trademark protection.

      4. How can I create my 3D printer design?
You can find print-ready files online at sites like:
Thingiverse
My Mini Factory
Pinshape

Or you can get started making your own designs:
Tinkercad
3D Slash
ScultptGL

       5. What colors can I choose from?
The library has several different colors of filament to choose from:

6. How much does it cost to print?
Patrons will be allowed up to three hours of printing time at no charge during a twelve month period. Prints will then cost $2 for set-up and the first hour of printing, $3 for up to two hours, and $4 for up to three hours

Prints must be paid for at the time they are picked up. After 14 days, the patron’s library card will be charged for the print and library services will be suspended until paid.

       7. How long will it take to get my project printed?
3D printing will be scheduled on a first come, first serve basis, and will be filled as soon as possible depending upon the number of people waiting, the time of day the request is made, and approximate length of build. Small jobs can take as little as 30 minutes to an hour to print. Larger projects can take up to the three hour maximum printing time allowed per job. All print jobs must end by 6pm or be scheduled for a future day. If you will not be present to watch the build (that’s the fun part!), or if the build is scheduled for a future time, we will contact you by phone or email when your project is finished.

       8. What kind of material does the 3D printer use?
The Dremel uses polylactide (PLA) filament. The PLA bioplastic is made from natural corn starch, making it environmentally friendly.

      9. Can I make bowls or eating utensils?
We do not recommend using your 3D printed object to hold or serve food. A study found that PLA, the filament we use, is Generally Recognized As Safe (GRAS) when used in contact with food. However the process of changing the plastic filament into a 3D object may make it not food safe. There are tiny cracks and crevices in all 3D objects where bacteria can grow. Hand washing will not remove it all.

      10. Is my 3D printed object Microwave or Dishwasher safe?
No, it will not be Microwave or Dishwasher safe. PLA is sensitive to heat. The 3D object can warp or crack into little pieces in the dishwasher and could cause damage to your machine.

You can safely hand wash your 3D object with lukewarm water and a mild anti-bacterial soap. This will remove any surface bacteria but will not remove the bacteria in the tiny cracks and crevices.
