3D printing is available at St. Martin Parish Library.

The Equipment

The St. Martin Parish Library owns a LulzBot Mini 3D Printer.  3D printers make it possible to print three-dimensional (3D) objects.  Many versions of 3D design software are available. One free and easy-to-use 3D CAD (computer-aided design) application is Tinkercad.

How it Works

The LulzBot Mini 3D Printer uses the Cura LulzBot Edition printing software. The print area is 6 in. x 6 in. x 6.2 in.  Once a design is created, it is saved as a stereo lithography (.STL) file.  This file format contains the surface geometry of a three dimensional object and is commonly used in 3D printing.

Filament is the term for the materials the printer used to print objects.  Filament is fed into the machine, heated to a high temperature, and then extruded in layers to build the item being printed. This process is known as fused filament fabrication (FFF).

3D Printing self-guided tutorials

If you have little or no technology experience, fear not. All you need is an open mind and a sense of adventure. Self-guided tutorials are available online for the Tinkercad application.  Another site with design tutorials is Fesora. Fesora is a website which provided online video tutorials designed for K-12 students, parents and teachers.

How to get a job 3D Printed

The Breaux Bridge Library houses the Lulzot Mini 3D printer. Patrons may create files independently and then submit a print job in .STL format to the library for printing.  To submit an independently created print job, use our “3D File Submission” form.

Designs submitted for printing should be your own work, be in the public domain, or be licenses under a Creative Commons License. For any reproduction of designs that are subject to Creative Commons Attribution license, the responsibility falls on the patron to follow the terms of the license.

One source for public domain files is . Files found here can be verified as being in the public domain.

Patrons wanting to have a 3D print previously designed by the library may select from one of the options shown below. To submit a request for one of these items, use our “3D Print Request ” form.

Note: All measurements are approximate and are given in inches.

  • Initial Charm measures 1.9 x 1.63 x .125. Estimated cost is 50 cents.
  • Heart Pendant measures 1.6 x 1.43 x .66. Estimated cost is 40 cents.
  • Personalized key chain measure varies based on length of name. Estimated cost is 50 cents.

The following guidelines and policies apply:

  • All print jobs are subject to review by library staff prior to printing. Controversial items will not be printed.
  • Print jobs are submit to a fee of 10 cents per gram of filament used. Payments must be made in cash at the time of picking up the print job.
  • Only .STL (stero lithography) files can be printed by the library.
  • Filament color options subject to change. In the event your chosen color is out of stock, staff will use the most similar color available at the time.
  • Due to possible hazards related to motorized and heated parts, library staff is solely responsible for operating the printer.
  • Prints are handed over AS IS. If the print requires supports or rafts, patron is responsible for removing those.
  • Due to the variable nature of 3D printing, wait time will not be estimated. You will be contacted once your item is ready for pick up.

*All guidelines and policies related to 3D printing are subject to change at any time.
