Why are stepper motors used in 3D printers?

FDM 3D printers need to do repeatable moves. Servos might give better and more repeatable torque, but they don't give very precise movement without the need of an encoder system. This makes Steppers cheaper and easier adaptable in most cases, even though there are some printers that use different motor systems.

Note that different printers like SLS printer do use several simple motors, especially for the system putting down powder, and the tilting system in the new mSLA Prusa uses - afaik - a simple motor doing one rotation per tilting motion.

 

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

High Torque, High Precision and Long life is Cloudray's core advantage
Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance.
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.

Higher Resolution,AvoidaHnce of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.stepper motor for 3D printer stepper motor for carving machine
Sturdy structure, extremely long life
High quality materials including bearings and shaft made in Japan
Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.
