3-D Printing 

Cute Mini Octopus

3-D printing, also called additive manufacturing, is any of various processes used to make a three-dimensional object from a digital file.  Material (in our case plastic) is laid down in layers to build the object.  The interior of the object is not filled with a solid; rather it has a honeycomb structure which keeps the object light while giving it strength.

The Library has a Bambu Lab P1S; it uses polylactic acid filament (PLA). PLA is a bioplastic made from renewable resources such as corn starch.  


Objects to print can be found on Thingiverse.com, pinshape.com, makerworld.com, or you can create your own using 3-D modeling software such as:

Tinkercad (free, online)
Blender (free, download)

You will need to download the print file in .STL format onto a USB drive.  You can preview and/or scale the object with the software above.  Look closely at the dimensions.  If you make changes, such as scaling, it will need to be saved again.
