3D Printing @ CDL

Join us for some 3D fun as we help you to use the 3D printer. We are offering 2 hour 3D printing sessions.  Please see our calendar for details on when the sessions are held.

The library has two 3D printers that were generously donated. The first  is a MakerBot Replicator 2  and the second is a Jellybox 1.3.  The printers can print objects in PLA plastic. You can search for pre-existing designs (thingiverse.com) or make your own (Tinkercad, OnShape, Fusion 360).   Printing even small objects can take some time. You only have 1.5 hours of printing time in a two hour session. Therefore we ask that you send us either a copy of the file you want to print or a link to the thingiverse object you want to print so we can review it and make suggestions on how to best optimize your print time.

If you are interested in registering please send an email to 3D@chelseadistrictlibrary.org with the following information:

  1. Preferred session date and time.
  2. A file or link of the object you wish to print (preferably an STL file). You can download STL files at thingiverse.com or design your own using CAD software.

Printing costs $0.10 per gram of printed plastic. After you have sent us the file/link of your object we will email you an estimate on costs and time to print. Registration must be at least two weeks before the actual date of the 3D session.

If you have questions please contact us at 3D@chelseadistrictlibrary.org

3D Printing Guidelines

  • Objects that can print in a 1.5 hour session are generally smaller than a human fist.
  • Most objects that can be printed within the time limit cost less than $3.00.
  • Objects can be resized smaller or made more hollow to shorten the print time.
  • Objects with a greater than 45 degree overhang will have support structures added automatically (see picture below). When removed these leave a slightly rough surface.
  • Objects with thin pieces hanging over empty air (dragon wings, or air plane wings) tend to not print out well.
  • Objects with a ton of detail (individual hairs, scales, etc) tend to take longer to print.
