3D Printing at the Library

Attention Patrons

We are not accepting 3D printing jobs until further notice. We apologize for the inconvenience.

The Cobb County Public Library has four MakerBot Replicator 5G 3D printers available for public use located at Switzer Library and our three regional libraries: Mountain View Regional, North Cobb RegionalSouth Cobb Regional, and West Cobb Regional Libraries.

3D Printer Details

  • 3D printing is currently $0.15 per gram of filament used in the printing process, with a minimum charge of $2.50.
  • All printing is done with PLA, a bioplastic made of corn. It is not recommended to print anything that needs to be heat resistant or super strong.  It is possible to make the model a little bit stronger by making its walls thicker or requesting more infill. Ask librarians about it and they will try to help out.
  • Due to demand and limited resources, the library will not print any job that will take over two hours. If there is something that would take longer than that, librarians are happy to help figure out how to break up the model into smaller jobs, scale the print, or refer you to one of the many paid 3D printing services. The library retains the right to refuse any print request for any reason.
  • Only library staff will have hands-on access to the 3D printers.

How to get an Object Printed

  1. Create a file
    1. Download an object file from a site like Thingiverse or Cubehero or use free modeling software like SketchUpBlender, and Mineways to create designs.
    2. If possible, export your object as a .makerbot file. Need help with the conversion? Just bring your file on a flash drive to one of our friendly librarians for assistance!
    3. Note: The library will print your file as is. If you need help optimizing or troubleshooting, just ask for help before submitting.
  2. Submit a print request
    1. Save your 3D printing file on a USB flash drive.
    2. Come into the library during open hours. Submit your flash drive and a 3D Print Request Form  to library staff. Staff or volunteers will help you make sure the model is ready for printing and ensure that it can be printed within our two hour limit. It is recommended that patrons create a backup of the project print file before submitting their flash drives.
  3. Collect your print
    1. After notification when the print is complete, it will be held at the library for ten days to allow time to collect the print and USB flash drive.  After ten days both become property of the library. PLEASE NOTE: “complete” does not always mean “successful.” The library will still notify when the print is done even if it does not come out perfectly. Re-prints will only be available in the event of machine malfunction.  Failed prints due to errors within the 3D model will still be charged for materials used.
    2. Prints can be collected during regularly scheduled library hours.
