Open-Loop Control Open-loop control is a system in which the 3D printer operates without feedback, relying solely on pre-programmed instructions. It controls movement, extrusion, and temperature but cannot correct errors in real-time, such as missed steps or filament jams. Open-loop systems are simpler and more cost-effective but less accurate than closed-loop systems. They are commonly used in entry-level and mid-range 3D printers. Proper calibration and maintenance are essential for reliable performance. Advanced printers use closed-loop systems for enhanced precision and error correction. |
