Can we use Extruder without Ramps Board On Arduino ?

Sir we want to use extruder of RepRap 3D Printer on Arduino instead of Ramps board, Is it possible that we have to disconnect all the wiring of Extruder and just use the wiring of Stepper motor and Hot End Power ? Is this extruder will work for catching and melting PLA ?
Our main goal is to use this Extruder and all stepper motor just on Arduino,because we are not interest for many shapes of printing,we are interest just in Geometrical shapes ( Rectangle etc )
This is our FYP project,,,
Thanks,

You need something like the RAMPS board to (a) convert the 5V signals from the Arduino to 12V, and (b) to increase the current from mA supplied by the Arduino output pin to Amps required by the heaters and motors. The RAMPS board could be replaced by some other circuitry.

You also need an Arduino (or similar) board to control the temperature, and interpret G-code commands and translate them to stepper motor pulses and heater outputs.

Thanks frankvdh :
But we want just to print a simple geometric shape through Arduino coading like C language ,
I think we have no need of G-Code here,And we can do it through in Arduino Coding,
When we used another Arduino ,then how we will synchronize all motors with two Arduino ?
Means we can't do this all work only in Single arduino ?
Please help us in this problem.

Yes, you can probably do without the Gcode interpreter, but you still need to control temperature of the head & bed, and generate pulses at the right time for your stepper.

You can do this with one Arduino. But you also need a RAMPS board (or an equivalent circuit).

I don't understand what you want to do?
squirt PLA without stepper motors

The RAMPS board provides
------- Stepper motor drivers the means to convert code into motor steps / pulses (high current)
------- Control of extruder heater (ON-OFF for temperature control) high current

Arduino alone can't handle much current (amps)

Perhaps a hot glue gun wiggled around by hand
with X - Y movements shouted at person holding it?
