3D Printing

3D Printing Policy

The Renfro Library has a 3D printer which creates objects from filaments made of a variety of materials. The printer reads digital files created via design software and builds the design object through iterative layers of the filament material, extruded through a heated nozzle onto a heated bed. The 3D printer may be used by anyone in the MHU community according to the following guidelines and limitations:

  1. Patrons may not use the printer to create objects that:
  • Violate local, state or federal law
  • Violate intellectual property rights and protections, including trademark, copyright, an/or patent law.
  • Pose a safety threat. Weapons, such as knives or firearms or any item that is dangerous or harmful, are prohibited from production.
  • Are obscene or socially inappropriate in the MHU community.
  1. Cost of 3D printing is calculated according to usage of filament by the gram and rounded up to the nearest dollar. Rates for filament by the gram vary according to the cost of the filament, but the most basic PLA filament, for example, costs $1 for every 35gm used. Most small, simple, hand-held projects would cost between $3 - $6. The minimum cost of any project is $1.00 regardless of weight.
  2. All print projects will be paid for prior to printing.
  3. Orphaned 3D printed objects will become the property of the Renfro Library if the object has not been retrieved after 6 months of production.
  4. Printing files will be deleted from library computers after printing is completed.
  5. Only library staff and authorized student workers may physically interact with the 3D printer and all 3D printer materials and peripherals.
  6. Filament materials other than PLA may be used in consultation with the library staff. Higher rates for filament use may apply to materials other than PLA. Filaments that produce noxious odors or toxic fumes are prohibited. These include ABS, polycarbonate, and filaments with nylon content.
  7. Patrons may not demand a new print in place of the original due to dissatisfaction with options pre-selected by the customer such as color, scale, quality, design, required support material.
  8. The library reserves the right to refuse printing any job.
