3D Printing: 3D Printing Requests

3D Printing

3D Printing Policy

Curriculum Materials/Media Center 3D Printing Policy

The Curriculum Materials/Media Center’s 3D printer is available to Campbell University students, faculty and staff to make three-dimensional objects in plastic using a design that is uploaded from a digital computer file.

I.  The Curriculum Materials/Media Center’s 3D printer may be used only for lawful purposes. No one will be permitted to use the library’s 3D printer to create material that is:

  a.   Prohibited by local, state or federal law.

  b.   Unsafe, harmful, dangerous or poses an immediate threat to the well-being of others. (Such use may violate the terms of use of the manufacturer.)

  c.   Obscene or otherwise inappropriate for the Library environment.

  d.   In violation of another’s intellectual property rights. For example, the printer will not be used to reproduce material subject to copyright, patent or trademark protection.

II. The library reserves the right to refuse any 3D print request.

III. Cost:  There will be a charge of $0.05 cents per gram of filament used in the printing process for all files over 100g.

IV.  The library cannot guarantee that prints will be printed in a timely manner--3D printing is unpredictable and printing issues do come up.

V. Items printed from the 3D printer not picked up within 7 days after being printed become the property of the library. Items must be picked up by the individual who submitted the print request.

VI.   Only designated library staff will have hands-on access to the 3D printer.

Preparing 3D Design Files for Conversion and Printing

Preparing 3D Design Files and Conversion for Printing

The MakerBot Replicator can fabricate 3D models from any 3D design software that is capable of exporting the file as a .stl file (STereoLithography). The MakerBot Desktop software also accepts .obj files. The .stl or .obj files must be converted to a 3D printer build file (i.e. a tool path) before printing with MakerBot Desktop for the MakerBots.

The CMMC has the MakerBot Desktop conversion program installed on the iMac beside the MakerBot in the Idea Lab/Makerspace.

MakerBot Desktop (5th Generation MakerBot) Conversion Procedure

Open your .stl or .obj file in MakerBot Desktop by clicking on Add File. Next, select settings. Remember, the MakerBot Replicator 5th generation printers are only compatible with PLA. However, you can adjust the layer thickness, fill density, raft, and support material options. Remember that 3D printing is an experiment. Choose options that you think will work best for your model. Next, click on Save Settings and then Export Print File. Save this file to your flash drive.

Thoughts to Consider Before You Design Your Object

•Think about what you are trying to do.
•Has this been done before (
–If it has been done before, can you modify something to fit your needs?
•Technical and/or artistic.
•Start simple.
•Think about limits of the 3D printer:
–Can’t print over hangs (without supports).
–Plastic shrinkage when printed.
–Minimum resolution/accuracy.
–You may need to split the object into multiple prints (i.e. box top and bottom).
–Can you interlock parts and/or glue parts.


Submit 3D Printing Requests

Email your file to after you submit a print request below.  Your item will not be printed without submitting an official print request.  You will receive a confirmation email for all print requests.
