Methods and apparatus for controlling an applicator head during additive manufacturing

This invention describes a method for precisely controlling a compression roller during 3D printing. It works by continuously monitoring the machine's internal signals that tell the print nozzle where to go, specifically the X and Y coordinates. From these signals, it calculates the direction the nozzle is moving and then adjusts the compression roller's position in real-time to match that angle, ensuring consistent smoothing or thickness control. The claims narrow this to sampling X and Y command signals at 2-millisecond intervals.

Why it matters: Real-time signal processing and control hardware has become more powerful and affordable since 2017, making precise, integrated roller control easier to implement directly on additive manufacturing machines.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateSignal sampling electronics, control software, roller actuator.
