Home based 3D printing is currently limited to printing plastics, but Canada-based Structur3d Printing is creating an add-on extruder to enable almost any desktop 3D printer to print a whole new range of paste-like materials.

Structur3D's Discov3ry extruder is an affordable, plug and play device which can easily be integrated with MakerBot, RepRap, Ultimaker and most other DIY 3D printers. This will enable makers to print a whole new range of materials, including silicone, polyurethane and icing sugar.
