Hey Dave,

The Makerbot is an FDM (fused deposition modeling) printer, which means it
is basically a fancy computer controlled glue gun. Officially supported
materials are ABS (the kind of plastic used for legos) and PLA (a corn
based plastic). Because of the way that the material is put down I'm not
sure you could get the detail that you would need for a functional fresnel
lens, also, it's not the clearest stuff in the world, even when it's very
thin. It might be possible to use a print as a negative for making a resin
cast... I don't know of anyone that has tried to create a lens on a
makerbot, but a quick search on thingiverse.com (makerbots model/design
sharing site) didn't turn up anything. Darcy's suggestion above seems like
another reasonable way to use a makerbot to create a fresnel. Good luck!
Let us know if you learn anything about making lenses with 3D printers!

-Angelo
