4010 Centrifugal Fans, Radial Blower Type for 3D printer

Radial Blower Fan 4010: Specifications and Use

As mentioned earlier, 4010 radial centrifugal blower fans, also known as "snail" fans, are widely used in 3D printers for cooling the hot end, which heats and extrudes the plastic. This helps prevent overheating and plastic deformation.

During 3D model printing, the plastic is applied layer by layer. To ensure each layer cools and remains stable, the 4010 fan is used. It cools the extruded plastic, reducing the chance of warping and print failures.

• Voltage
• Speed

Setting up 4010 Radial  blower fans on a 3D printer is typically done using dedicated software (such as Cura, PrusaSlicer, etc.). Users can adjust fan speed and turn it on or off based on specific printing requirements and the type of filament being used

How to Choose a 4010 Radial Blower Fan:

If your fan has failed and needs to be replaced, start by removing the old fan and checking the label on its rear side. This label will provide information about the fan’s voltage and other characteristics.

First, ensure that the fan size matches your 3D printer’s requirements. The standard size for the 4010 radial fan is 40 mm x 40 mm x 10 mm (width x height x depth).

Also, check the voltage of the new fan, as it needs to be compatible with your printer’s board. A mismatch in voltage can cause immediate failure upon connection. 4010 fans are available in 5V, 12V, or 24V variants. Voltage is typically marked on the printer’s power supply. If not, use a multimeter to measure the voltage, and always observe safety precautions!

Once you’ve identified the key fan specifications, consider the balance between power and noise levels. The more powerful the fan, the louder it will be. Conversely, a lower-powered fan will be quieter but may not provide sufficient cooling, potentially leading to overheating or equipment damage. A recommended fan speed is around 5000 RPM to ensure optimal cooling and manageable noise levels.

Finally, always refer to the manufacturer’s instructions and recommendations when selecting and installing a fan in your system.
