Slicer for 3D printing from different materials

[21Scorpio21 0]

Hello. I´m designing new type of 3D printer that will work like FDM 3D printer. However I will 3D print from different material than plastic. And here comes my problem. I don´t know which slicing software should I use because I will use Universal G-code sender to send gcode from computer to 3D printer. But at first I need to make gcode. I´m using 5mm nozzle and I will 3D print from something like clay.

 

Any ideas for slicer?(there is no way that I will make my own slicer)

 

thanks for any advice
