Stepper motors for 3D printers

Krishna is an engineer from Croatia who likes to do some crafts in his spare time, and recently he fell in love with 3D printing projects. He likes to use 3D printers to make all kinds of interesting little toys. He contacted us to ask what kind of motor he should choose to use in his 3D printer and if the motor was powerful and precise enough. 3D printers require precise motion, and stepper motors are perfect for providing controlled motion. After discussing Krishna's application, we recommended our stepper motors as the best solution.

Client needs

Through extensive discussions with Krishna, we learned about the key requirements for his 3D printer project. Precise positioning and speed control were critical for accurately depositing material layer by layer. Our team communicated with Krishna about his needs and determined the torque, step resolution, and driver interface required for the stepper motors. Krishna also needed compact motors that could fit inside the printer frame. After careful consideration, we recommended our 42HS40 stepper motor as the solution.

Solution

Lunyee's 42HS40 stepper motor delivers 1 N.m. of holding torque for fast acceleration and deceleration. With a resolution of 1.8 degrees per step, it enables very precise motion and excellent positional accuracy. The integrated encoder provides speed and position feedback. The small NEMA17 frame fits into tight spaces and is a stepper motor model often used in 3D printers. We also recommend a matching driver to avoid model incompatibility issues.

Evaluation and feedback

We communicated closely with Krishna during the transaction process. Our engineering team remotely provided him with technical guidance to help him install and utilize our motors. Upon receiving the motor, Krishna immediately tested it on the machine and was very pleased with the results. He said the motors ran smoothly, and he was satisfied with the print resolution and print time.
