Cura
Cura is the 3D model to toolpath Slicer by Daid (David Braam). Cura is free Open Source software released on the AGPLv3 license.
It is currently maintained by Ultimaker who employed David to work on it. Cura is well suited for Bowden-extruder machines like the Ultimaker and most Delta-bots. also you can use it with most of reprap printers. Cura features it's own Slicing engine, GCode sender and other tools to provide an "all in one" solution for 3D printing. However all components can be used on their own.
