3D Printing

taz5

The library maintains two Taz 5 3D printers for use by the public in the library. Patrons must read and sign our 3D printer policy agreement below before using the printer to print a model.

What is 3D Printing?

3D printing works by feeding plastic filament into a heated print head. The print head melts and extrudes a very thin layer of plastic filament onto a printing surface and then extrudes another layer on top of that. Layers of plastic are built on top of each other over and over, sometimes hundreds of times, until you have your finished model. You can view a time-lapse of one of our printers here.


Where do the designs come from?

Our printers use the .stl file format for 3D models. You can download model files from popular 3D communities such as Thingiverse and Yeggi or you can create a model yourself from scratch with free programs like Tinkercad and SketchUp. 3D printers are part of our Maker Space with tools to help you design your own models here at Carnegie-Stout.

How long does it take to print?

It depends. Models just a few inches high can have hundreds of layers and can take hours to build. More intricate models may take longer to print but may not take more filament. Cura software used for rendering .stl files gives estimated print times.

How much does it cost?

Model cost depends on its printed weight not finished weight. Printed weight may include rafts and supports necessary to print your model correctly, but are removed when your print is finished. Your printed weight will be more than your models finished weight. Models will cost 10¢ a gram. You can find out your models weight by loading the file in Cura. You can download Cura at https://www.lulzbot.com/cura



Carnegie-Sout Public Library 3-D Printer Use Policy:

The library maintains two Taz 5 Printers for use by the public.

Policy:

Use of the 3-D Printer is at the discretion of library staff. The library reserves the right to deny use of the equipment.

It is expressly prohibited:
  • To print any object that is intended to physically harm, or attempt to harm, a person or animal in any way.
  • To print obscene or inappropriate materials.
  • To print any object that violates or infringes upon a patent, trademark, or other proprietary right. Use of the 3-D Printer and associated equipment shall follow all legal guidelines. U.S. Copyright Law governs the making of photocopies or other reproductions of copyrighted material.

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.

Typically your model will be printed within 48 hours. However long print queues and breakdowns do happen and therefor we cannot guarantee completion times.

If a print fails, it may be attempted only two more times.

Items that are not picked up after two weeks (14 days) will become property of the Carnegie-Stout 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.


Only designated library staff and trained patrons will have access to the 3-D printers.


The library is not responsible for the subsequent safety of any item made with the 3-D printer.



Procedure: 

Patrons must design, scan, image, create or download their own models for use on the 3-D Printer; library staff are available for
assistance only.

The maximum printed area must be smaller then 11.7in x 10.8in x 9.8in.
 
Files must be in 
.stl file format. Files can be dropped off on a USB flash drive at the reference desk.

Cost: The library currently charges 10 cents per gram of PLA plastic.


The library reserves the right to schedule only one print per week per person or entity.


The library uses only PLA filament at this time and colors may be limited


Print times are estimated; we cannot guarantee print times.


The library will render all files in Cura software before printing. Patrons may preview the file in Cura themselves by downloading the free software from the following website: 
https://www.lulzbot.com/cura Patrons should bring in non-rendered .stl files to print.


Patrons can submit 3D models to print by using our 3D Printing Submission Form.
