What the Slimline Stepper Motor 25mm does

The E3D Slimline Stepper Motor is an ultra-slim NEMA17 stepper motor built for Titan extruders and other extruder-focused setups where low weight and compact size matter. With a 25mm body length, 12.7N-cm holding torque, and a 0.9° stepping angle, the motor is designed to balance size, weight, torque, and shaft compatibility for extrusion duties.

This slimline motor is optimised for minimal load without sacrificing performance. The compact format helps reduce bulk on the motion system while still providing the output needed for extruder applications.

Key features of the ultra-slim NEMA17 extruder motor

• Ultra-slim NEMA17 profile: Designed for installations where a standard motor length would add unnecessary bulk.
• 25mm body length: Keeps the motor compact for space-conscious extruder assemblies.
• 12.7N-cm holding torque: Provides the torque output stated for reliable extruder use.
• 1.4 A/phase rated current: Matches the specified electrical rating for motor setup and tuning.
• 0.9° stepping angle: Offers finer step resolution than a typical 1.8° motor.
• Balanced design approach: Custom-designed for size, weight, torque, and shaft compatibility.
• Included pluggable cable: Supplied with a 1000mm cable for connection flexibility.
• Low overall weight: Weighs 162g on its own and 190g with the included cable.

Where the 25mm slimline stepper motor fits best

This stepper motor is suited to Titan extruder builds that need a lighter, shorter motor without giving up the core performance required for filament feeding. The slim body can be useful in compact printer toolheads and space-limited extruder layouts.

The low-weight design also makes sense for users looking to minimise added mass on the printer while keeping a motor that is purpose-built for extruder use. For builders comparing a compact NEMA17 motor for Titan extruders, this model is focused on practical balance rather than maximum size or weight.
