Here are just a few options to make your 3D printed projects even more colorful and impressive. As you can see, 3D printing is about more than just static miniatures. Implement at least a couple of the above projects, and your knowledge in the field of 3D printing (and not only) will expand significantly. Well, if the above electric motor designs are too easy for you, then why not create your own?
stepper motor choice, which is better
With the advent of 3D printers, people's lives have become much easier. Devices are successfully used in many areas - dentistry, industry, jewelry and medicine. Now a 3D printer is not a luxury item, but a design that is quite affordable. But still there are those who decide to independently manufacture printing presses. Next, let's talk about how to choose a stepper motor for a future 3D printer and what features should be taken into account.
Motor on a 3D printer
In the design of a 3D printer, the main function for the movement of the extruder along the axes is performed by stepper motors. They have low weight and high torque.
A stepper motor is a motor without a commutator, whose rotation is not smooth, but discrete (in steps). By setting the speed and duration of the pulses, you can make the device rotate in a certain direction.
In this case, it is possible to adjust the direction of rotation and the number of revolutions of the rotor.
If we talk about the design of such devices, then there are three main types:
- Motors with variable magnetic resistance - have several poles on the stator and a rotor made of soft material, and 3 windings independent of each other. This type is practically not used.
- Permanent Reluctance Motors - Includes stator and magnetized rotor. Such motors have 24 to 48 steps per revolution.
- Devices combining variable and constant magnetic resistance (hybrids) - combination of the best properties of an AC and a constant rotating motor. The number of steps is from 100 to 400.
The hybrid engine is the most common design, which, in turn, is divided into unipolar and bipolar types.
Which stepper motors to choose for a 3D printer: the best options
When buying a rotator for a 3D printer, you should pay attention to the following parameters:
- rotating structure size;
- holding torque - 2.
5-4 kg/cm; - rated current - optimal version for 1.7 A;
- Shaft - Diameter must match the design of the printer.
The most common motors that are installed on the design of the printing device are bipolar with four leads. Such structures in the event of a breakdown are easy to find and replace.
NEMA marked rotary motors are installed in 3D printers.
NEMA is a National Electrical Manufacturers Association that standardizes rotating devices in terms of flange size and fit. This standard allows different manufacturers to produce engines according to certain parameters, depending on the marking.
Most popular models in the NEMA series:
- NEMA 17 with 42*42mm flange;
- NEMA 23 with 57*57mm flange;
- NEMA 34 size 86*86mm.
Stepper motor drivers for 3D printer
To control motors in 3D devices, drivers installed in the board slot have been developed.
There are several types of drivers:
- Constant voltage - such drivers are inefficient and are used in a product with low speeds.
- Two-Level - These controllers support step and half step modes. They reduce engine heat and are efficient in operation.
- PWM drivers are the most popular on the market. They are highly intelligent and have many additional features.
Also, when choosing a driver, you should pay attention to the following parameters:
- current strength;
- supply voltage;
- presence of optoisolated inputs;
- availability of resonance suppression mechanisms;
- availability of protocols necessary for engine operation;
- surge protection;
- micro stepping;
- driver quality.
It is quite possible to assemble a high-quality 3D printer if you follow the recommendations and carefully study the design devices. It is quite possible that such a printing press will cost its owner less.
