Let’s have fun…in 3D!

 



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).

Using the 3D Printer

If you have little or no technology experience, fear not. All you need is an open mind and a sense of adventure. 3D printing is recommended for ages 12+.  Patrons are invited to come play, learn, and explore.

The Breaux Bridge Branch Library houses the LulzBot Mini 3D printer.  Self-guided tutorials are available online for the Tinkercad application, handouts are provided. If you would like personal assistance, call 337.332.2737 to schedule an appointment.  

Another site with design tutorials is Fesora. Fesora is a website which provided online video tutorials designed for K-12 students, parents and teachers. Want to create an apple pencil holder in Tinkercad? Click here for the Fesora tutorial.

Patrons may create files independently and then submit a print job (in .STL format) to the library for printing. These jobs are subject to a printing fee. 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 licensed under a Creative Commons license .  For any reproduction of designs that are subject to a Creative Commons Attribution license, the responsibility falls on the patron to follow the terms of the license.

One source of public domain files is http://www.yeggi.com/q/public+domain/ .  Files found here can be verified as being in the public domain.

Patrons not wishing to create a file or locate a public domain or creative commons license file can request a library-created 3D printed item, you may select from one of the library-created designs posted below. To submit a request for one of these items, use this "3D Print Request " form.

 Filament Color Options*
*as of May 2017, orange and  black are no longer available
 

 
    The following guidelines and policies apply*:
  • All print jobs are subject to review by library staff prior to printing.  Printing weapons or other controversial items will not be permitted.
  • Designs submitted for printing should be your own work, be in the public domain , or be licensed under a Creative Commons license . For any reproduction of designs that are subject to a Creative Commons Attribution license, the responsibility falls on the patron to follow the terms of the license.
  • For patrons with a valid St. Martin Parish Library card and an account in good standing, there is no cost to print files completed in a program sponsored by the library.
  • Print jobs will be subject to a printing fee of $0.10 per gram of filament required to print the file. Payments must be paid in cash when you pick up your print at the Library.
  • Only .STL (stereo lithography) files will be printed by the library. STL is a file format that contains the surface geometry of a three dimensional object and is commonly used in 3D printing.
  • The colors available may change without notice, and we cannot guarantee that your selected color will be available. In the event that your chosen color is out of stock, we will use the most similar color available.
  • Due to possible hazards such related to motorized and heated parts, library staff will be solely responsible for operating the printer and handling print jobs. 
  • Prints are handled over AS IS. If the print requires rafts of supports, you will be responsible for removing those.
  • Due to the variable nature of 3D printing, wait time will not be estimated.  You will be contacted when your item is ready for pick up.

 *As this is a new technology being offered by the library, all rules are subject to change at any time in response to actual use and experience.
