Snapmaker Part Cooling Fan for the Snapmaker U1 3D printer is an original replacement fan designed to actively cool the printed material immediately after it is deposited on the print bed. It ensures sharp edges, precise overhangs and clean surface quality on all common filaments such as PLA or PETG.

Original part for Snapmaker U1

This is an original replacement part directly from the manufacturer Snapmaker with catalogue number 12032. The fan is 100% compatible with the Snapmaker U1 multi-material 3D printer and requires no modifications or adapters. Simply swap the old unit for the new one and the printer is immediately ready for further work.

Active print cooling for sharp details

The part cooling fan quickly solidifies the molten plastic by blowing air onto it right after it is deposited on the model. The result is sharper corners, better overhangs without the need for supports, and a cleaner surface on fine details. It is precisely the quality of cooling that often decides between an average and a precise print.

Essential for PLA and PETG

Without a working part cooling fan, it is not possible to correctly print materials that require active cooling - especially PLA and PETG. For technical materials such as ABS or ASA, cooling is reduced or turned off, but the fan's functionality itself is still necessary for the correct temperature control in the hotend.

Easy replacement without specialised tools

Replacing the fan on the Snapmaker U1 is a matter of a few minutes. Just disconnect the connector, unscrew the mounting screws, insert the new fan and reconnect everything. The firmware automatically detects the fan and there is no need to calibrate or reconfigure the printer.

Reliable solution for long-term operation

Fans in 3D printers are a mechanical component with a limited lifespan - dust, vibrations and continuous operation gradually reduce their efficiency. Having an original replacement unit on hand means minimising printer downtime. We recommend keeping this part in your workshop as a preventive spare.

Signs that replacement is needed

It is appropriate to replace the part cooling fan when it starts making noisy sounds, does not reach full speed or stops completely. This may show on prints as sagging overhangs, unsightly top layers or deformed details. In some cases, the printer will directly display an error message from the firmware.

For multi-material printing on Snapmaker U1

The Snapmaker U1 is a multi-material 3D printer with support for several filaments in a single print job. In order to switch materials without compromising quality, cooling must be in perfect condition - otherwise problems occur at the interfaces between colours or materials. The original fan guarantees the expected performance of the entire printing system.
