We'd like to showcase the bespoke work we've been doing using the Parallax Propeller. The Prop and Prop2 are unique multicore microcontrollers made by Parallax Inc; their architecture allows for executing parallel tasks in hardware, which makes them perfect for things like autopilots or applications that need to control a number of motors and sensors at once. The Prop is a capable brain for small and medium robot designs, and an excellent spine for more complex designs where a Pi or other SBC has to do the abstract thinking.

The organometallic filament we are developing is capable of holding a nice sharp edge, as demonstrated here with a piece of steak. This test suggests possible medical and industrial applications as well as 3D printed cutlery, all from a filament we generate here on-site that is compatible with a standard extruder. Move over titanium spork!
