3D Printing in the Bollinger Digital Fabrication Lab, Holman Biotech Commons: Home

We're up and running in our newly renovated lab at the Holman Biotech Commons and are accepting 3D printing requests for academic, clinical and research projects only.  We are currently operating at a limited capacity and turnaround times are longer.  Please plan ahead and submit your request at least 5-7 business days ahead of time.

Submit 3D Printing Request

Please read these steps before sending your first file

Please read these steps before submitting for 3D Printing

  • Required file formats: .STL (Stereorlithography).  For more experienced users, we also accept .form and 3mf files.   
  • Check your file for errors.  Suggested tools:  
  • Submit each part as a separate .stl file, up to 5 files per request 
  • Keep each file under 100MB
  • Cost 
    • Free for academic, clinical and research projects for Penn faculty, students and staff. Detailed description of the project is required to qualify for free printing!  
  • Check out our materials page for details about the materials we offer
  • Free for personal projects at the Educational Commons

If you need another material or a guaranteed turnaround, we recommend searching MakeXYZ3D HubsShapeways or Xometry to find a local 3D printing service to complete your project for a fee.

For other fabrication resources check out Laserfab for Laser Cutting, Waterjet Cutting and Metal Fabrication Services!

3D Printing Policy

I.  The Libraries’ 3D printers may be used only for lawful purposes. No one will be permitted to use the Libraries’ 3D printer to create material that is: 

  • Prohibited by local, state or federal law or by University of Pennsylvania policy. 

  • Unsafe, harmful, dangerous or poses an immediate threat to the well-being of others. 

  • In violation of another’s intellectual property rights; to reproduce material subject to copyright, patent or trademark protection. 

II.  Penn Libraries reserve the right to refuse any 3D print request.  For example, print requests may be refused if it's deemed that there is another fabrication option that is either more appropriate, less costly, and/or more environmentally sound. 

III. Only designated Library staff will have hands-on access to the 3D printers.
