3D Printing

We have two processes for 3D Printing at the library. Through the
3D Print Service, opens a new window, patrons can submit files on the Arapahoe Libraries website and our technology specialist team will prep the files and print them, then contact the patron when the print is ready to pick up.  

The 3D Printers available in the Makerspace are available for reservation for independent patron use. Patrons must first go through a certification process to learn and then demonstrate proper use of the printers and slicing software through a series of guided appointments.   


The easiest way to 3D print through Arapahoe Libraries is submitting an STL file through the 3D Print Request Form. 



  • This is a great option for beginners as it requires no knowledge of 3D printers.  
  • Patrons can pick up completed prints from any of the Arapahoe Libraries locations. 
This is only applicable to prints under 5 hours of print time. If you’re unsure of the print time and size of your object does not matter, select “yes” to file resizing.       
  • Patrons are unable to request specific colors. 
  • Prints are one at a time. 
  • Build Volume: 9.84"×8.3"×8.3"  
  • Filament Type: PLA 


For patrons who would like to learn more about how 3D printers work or have more control over the settings of their prints, being 3d print certified through the Makerspace is a great option.  

To start certification, request an appointment on the Makerspace page under Contact Us, opens a new window 

  • Select “Equipment” 
  • Select “3D Printing”  
  • Indicate in the form that you are interested in starting 3d printing certification. 



  • Learn more about the 3D printing process  
  • Prepare files to your specific preferences  
  • Pick a filament color from our selection  
  • Longer print times  
  • Must complete a series of guided appointments and be approved for use  
  • Build Volume: 9.84"×8.3"×8.3"  
  • Filament Types: PLA, ABS, PET  
  • Total of 4 reservations per patron per month, regardless of printing times.

The process of preparing an STL file for printing on a 3D printer is called slicing.
