The Biomedical Library's 3D printers are available to the Penn community of students, faculty and staff to make three-dimensional objects in plastic using a design that is uploaded from a digital computer file.
I. The Library’s 3D printers may be used only for lawful purposes. No one will be permitted to use the Library’s 3D printer to create material that is:
II. The Library reserves the right to refuse any 3D print request.
III. Only designated Library staff will have hands-on access to the 3D printers.

What can I print?
To print a file it must be exported as a steryolithography file, with an STL extension (.stl) This .stl file must be watertight with manifold edges and no inverted triangles. Files can be fixed for free using a cloud service such as Microsoft's 3D printing platform netfabb https://netfabb.azurewebsites.net/ If the .stl file you give the Biomedical library is not compatible with our printers we may use software to attempt to repair it, in which case we will notify you first.
Manifold or Watertight
The mesh or surface of the 3D model must be watertight and a solid. More technically, all faces of the object must construct one or more closed volume entities. When the faces are not fully closed, they produce gaps or holes in the model and those holes and gaps will keep the model from printing correctly.
Formlabs Form 2
Stratasys UPrint SE Plus
The 3D model must fit within the build envelope of the Stratasys uPrint, which is 203 x 203 x 152 mm (8 x 8 x 6 inches). The minimum thickness of a layer is 0.254 mm (0.010 in.) so the smallest features that will accurately be produced must be at least this value. It is recommended that part thicknesses be at least 0.254 mm or greater.
Ultimaker 3 Extended
The 3D model must fit within the build volume of 215 x 215 x 300mm (8.5 x 8.5 x 11.8 in). The minimum layer thickness is 0.25mm so that is the smallest detail that can be produced with this machine. The Ultimaker prints PLA and ABS plastic, and a flexible material (TPU95).
The Zyyx has a maximum build volume of 260 x 225 x 200mm. This printer prints in nylon, and PLA and ABS plastic.

Submit your Model
Once you have completed your model, submit your file on 3dprint.library.upenn.edu/submit you will have options to select your preferences and provide specific instructions for the print staff, file size is capped at 100MB. If there are any issues with your files, we will notify you via email.
We look forward to printing with you!
