An add-on paste extruder for FDM 3D printers

We've recently launched our Discov3ry paste extruder add-on, an affordable way to expand desktop FDM printers to many new paste materials. Happy to answer any questions.

What are the limitations on pastes used?
I may consider purchasing an FDM machine if I can get a certain paste through it.
The limitations are mostly driven by the maximum viscosity of the material, and we don't use any heat or warming, so the materials should flow at room temperature. (This may change in future product iterations).
Pottery clay, for example, is too hard for us to extrude properly, though we're working on techniques for working with somewhat diluted solutions.
There is a long list of materials that our extruder is pretty good with including:
- Silicone
- Polyurethane
- Latex
- Wood Filler
- Conductive paint (we've tested with [Bare Conductive's](http://www.bareconductive.com/) product)
- Icing sugar
- Nutella
Here is a gallery of some prints we've done in clear and white silicone, which we purchased at a hardware store as in caulking tubes: http://imgur.com/a/ON7Lv
Hope that's helpful.
