What is 3D printing ?

3D means when you use the 3 axis "x, y, and z" to make a real shape you can hold with your hands.

To make height "z axis" the machine makes layer up layer, it takes along time belongs to the shape and it's volume .

3D printers belongs to CNC machines "Computer Numerical Control".

So you need to connect it to a PC desktop or at least you will need a PC to make slicing for the shape.

Slicing ?

slicing means to make the object you designed to a simple layers so the machine can read its code which call "g-code"

g-code : is the coordinates for the axis motors. eg. :

X88.250 Y84.750 E67.90132

G1 X80.044 Y84.750 E68.41307

G1 X80.043 Y81.250 E68.63134

programs like Repetier can help you to slice and give you the g-code, then you save it on a SD card or just connect the machine to your PC.
