Material processing unit controlled by rotation

This is an add-on tool for a CNC machine, which is a computer-controlled cutting or shaping device. This tool attaches to the machine's spinning part and has a small computer inside that monitors the spin speed. It can then perform different tasks, such as 3D printing by extruding material, based on how fast the CNC spindle is rotating. The claims specifically focus on additive manufacturing using an extruder.

Why it matters: Since 2017, the cost and processing power of microcontrollers have dramatically decreased, simplifying the control logic. Concurrently, additive manufacturing extruders have become more precise and accessible, making this integrated unit more practical to build.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateMicrocontroller, speed sensor, extruder, control software
