Student using 3D printer in the lab

College of Engineering and Applied Science 3D Print Farm

The CEAS 3D print farm is seeking to enable engineering students to make their design ideas a reality! No matter if you are designing a gear for your mechanical design class or making a replacement cupholder for your car, the print farms array of 28 MakerGear M3 printers can print what you need. 

Here at the lab, we offer PLA Printing for any part with dimensions smaller than 203 x 232 x 203 mm in: red, blue, yellow, green, purple, orange, and black.

Using Rhodes 801 Printing Lab for Class Projects

  • Email us at to request a class code to use with 3dprinter OS. In the email, include the following information:
    • Approximately how large are the expected parts for each student? 
    • How many students in total will be printing? 
    • What is the timeline for when the parts are expected to be printed? 
    • Are there any special considerations for material properties, color, or structure for these parts? 
  • The class code will be used by students to access a special group of printers dedicated to your class!

Note: Although the lab gives special access to printer groups for class use, it is the responsibility of the students to submit their parts in a timely manner to have them for class. If students all wait to print before a deadline or if they don’t account for possible print failures the delay in receiving their part is their own responsibility. It is with this in mind that I encourage you to have your students print earlier rather then later. Contact with any questions or concerns

Using Rhodes 801 Printing Lab (CEAS Students Only)

  • Go to 
  • Click start now in the upper right hand of the page
  • Log on using the SSO tab. Enter University of Cincinnati into the school selection. 
  • Enter your UC credentials  (Restricted to CEAS faculty, students, and staff) 
  • Upload your 3D file (.STL, .3MF, or .STEP) into the system using the ADD FILES button under the Files menu.
  • Slice your part using the SLICE BUTTON located in the projects tab under the Files menu
    • Adjust the layer thickness, shell thickness and infill to the desired levels.  Or use the default settings which will work for the vast majority of cases. 
    • Determine whether or not you should click on the supports feature
      • Yes- If your part has overhang angles over 45° 
      • Yes- if your part has complex, intricate, or detailed features (e.g. Features that extend away from the main body, extruded text, shells, cantilevers, and floating structures) 
      • No- if your part does not fit the above descriptions. Then do not click on supports feature
    • Click SLICE
  • Click the PRINT button
    • Select your desired printer (see printer description for material information) If the printer icon is green, the printer is available, and your print will immediately start when the PRINT BUTTON is pressed. If the printer icon is yellow the printer is in use and your part will be added to the queue for future processing when you press the QUEUE BUTTON.
  • Select the printer's menu to view the current status of your print job (by the printer)
