3D Printing

3D Printer Policy:

The Carroll Public Library is pleased to provide access to a Makerbot Replicator + to our patrons as part
of the Makerspace. The purpose of our 3D printer is to encourage users to learn about new
technologies, exercise their imaginations, and to create and design new projects. All designs will be
reviewed by Carroll Public Library staff, who reserve the right to refuse any 3D print job. Size of the file,
timing of printing, and maximum length of time allowed for each print job will be regulated according to
demand and equipment restrictions. The library reserves the right to limit the number of print requests.
Abuse of the 3D print service may lead to denial of future use.

All 3D print jobs must adhere to the following guidelines:

To submit a 3D print job, patrons must:
– Have a Carroll Public Library card in good standing with fines not exceeding $0.00.
– Upload the .stl file through the library’s 3D Print Request form and fill in all other required
information. All print jobs must fit within the dimensions of the Markbot Replicator +
parameters: 11.6 x 7.6 x 6.5 inches, or 5.73 cubic inches. Additional technical specifications can
be found here: https://www.makerbot.com/3d-printers/replicator/#tech-specs. Customers are
solely responsible for the creation and editing of design files. All files will be deleted from the
system following the completion of the print job.
– Approve the estimated cost of the job, as calculated by library staff. Prices will be estimated on
a $0.10 per gram calculation and estimations may vary from the final price. The cost of printing
will be added to the patron’s account when the print is finished. Patron must pay this amount
before the item can be claimed. Anything over $20.00 and over requires a down payment of half the total price.
– Retrieve all completed print jobs within 14 days of printing. Any unclaimed jobs will become
property of the Carroll Public Library and no refunds will be issued.

Patrons must acknowledge the following:
– 3D print jobs will be printed in an order determined by library staff; library staff take into
consideration the print job size and color when determining the order, as well as estimated
completion time. Print jobs must be completed when the library is staffed. Large print jobs may
need to be divided into smaller jobs. Turnaround depends on demand; library staff will give
patrons an estimate of turnaround after their print job has been approved for printing.
– Only filament supplied by the library can be used, and availability of color may vary.
– Library staff will print .stl files as they are submitted and do not provide corrections or
alterations. Print job failures not due to library or equipment malfunction are the responsibility
of the patron and the cost will be added to the patron’s library account.
– By submitting content or objects, the patron agrees to assume all responsibility for, and shall
hold the Carroll Public Library harmless in all matters related to patented, trademarked, or
copyrighted materials.
– The Carroll Public Library is not responsible for any damage, loss, or security of data arising from
the use of its computers or network, nor for the functionality or quality of content produced on
the 3D printer. In the instance of printing failure, 3D print jobs may only be attempted twice

3D print jobs must not:
– Be in violation of any Carroll Public Library policies.
– Be prohibited by local, state, or federal law.
– Be in violation of another’s intellectual property (i.e. be subject to copyright, patent, or
trademark protection).
– Be obscene or inappropriate.
– Be unsafe, harmful, dangerous, or pose a threat to the well-being of others.
