Fast desktop-scale extrusion 3D printing

This kind of 3d printer generally uses stepper motors, not servos.

From what I can see, this printer appears to use stepper motors too. I'd believe it's real-time.

The X axis is held in place vertically by the 2 shiny metal rods you can see, and is dragged back and forth by the black rubber belt, which is controlled by a stepper motor.

I know, I have several printers mtself. They are using only servos. Which is why it's faster probably. EMJ-04 series.

The rate at which it jumps around is just ridiculous though.

They're actually using servo motors! They refer to it as a "servo-driven parallel gantry system" in the abstract.
