What is "Print Jerk"


Recommended Posts

Posted · What is "Print Jerk"

In physics, jerk (or jolt) is the rate at which an object's acceleration changes over time. Acceleration is the rate at which speed changes over time. Speed is the rate at which position changes over time.

 

In 3d printing the position and speed are what you would expect from physics, but acceleration and jerk are subtly different. Acceleration is loosely defined as the speed increase (so it is defined as a speed in m/s, not m/s2). Jerk is similarly defined as the speed at which the aforementioned "acceleration" can change (also defined in m/s, not m/s3).

 

TL;DR: The rate at which acceleration can change.
