Information about 3D printer parts

[Amanullah47]

I am a Master's student of International Islamic University Malaysia. For my research purpose I need some important information from you. It is related to 3D printer.I have one 3 axes(X,Y,Z) mchine. I am using LabVIEW 2014 and NI PCI 7344(motion controller). This motion controller can control upto 4 servo motors and can give 2 PWM signal.
I am doing research on " DEVELOPMENT OF A HYBRID SYSTEM COMBINING RAPID PROTOTYPING AND CNC MILLING"
Working Procedure:
(a) At 1st i will attach the CNC milling spindle along with the "Z Axis" and perform the CNC milling operation
after that
(b) I will take out the CNC milling spindle and attach the "3D printer's multi nozzle EXTRUDER" along with the "Z Axis" to perform RAPID PROTOTYPING OPERATION
**I need the following information**
1. What are the parts should i buy for workable my 3 axes machine as a 3D printer?
2. Which controller can be controlled from "LabVIEW" regarding this matter? (such as RAMPS, RUMBA etc)??
3. I am planning to buy "Diamond Hotend multi nozzle heat extruder" will it be easy to use for my research purpose??
If "NO" then please kindly suggest me which one will be worthy for my research purpose.
