How To Avoid Failure Of 3D Printing Equipment?

Many novices will have problems such as clogging of the printer nozzle and the printing model not sticking to the printing platform when printing. These are all related to the insufficient cleaning of the 3D printer, and everything is inseparable from the later maintenance. For example, if the 3D printer is not maintained for a long time, There are bound to be small problems and even big ones. In fact, as long as you do the daily maintenance of some key components of the 3D printer, there will usually not be too many failures. So how to avoid it? Next, Yuanzhu will take you understand.

Clean the nozzle motor on time

No matter whether the gap between the bottom plate is too small, impurities remain in the nozzle, the nozzle is blocked due to the wrong material line and conversion parameters, or the nozzle cannot be discharged due to the entanglement of the material disk, it will cause the nozzle motor to run deviated, and the friction formed by the feeding gear and the feeding line will cause debris. Slag deposits can interfere with the conveying force distance in the extrusion structure and can fall into the nozzle feed port, jamming the line of material entering the nozzle.

Maintain the printer's optical axis on time

The X-axis and Y-axis parts of a 3D printing device run very fast during the printing process. To reduce frictional resistance and noise, all-optical axes of the printer are greased. It is recommended that the user find the grease box from the accessory box at intervals of 2 months or when the noise of the printer increases, and wipe a layer of grease on all the optical axes of the printer. If the user uses a high-intensity printer, it is recommended to perform optical axis maintenance once a month.

Z-axis screw on-time maintenance

The Z-axis of the 3D printer is driven by a screw. If the user feels that the noise increases when the Z-axis platform runs up and down after using it for a period of time. You can find a few drops of oil or ordinary lubricating oil on the screw from top to bottom, then enter the control panel, and manually operate the Z-axis motor to move up and down 10 times, so that the lubricating oil spreads symmetrically to the surface of the Z-axis screw.

Regular maintenance of timing pulley fixing screws

The X-axis and Y-axis of the 3D printer are driven by timing belts, and the timing pulleys on the timing belt shafts are likely to loosen during long-term fast forward and reverse switching. It is recommended that users use a 1.5mm Allen key to tighten all the fixing screws of the timing pulley once a month.

Timing belt tension

Due to long-term high-strength stretching, there may be slight slack, which interferes with the positioning accuracy of the nozzle. At this time, the timing belt needs to be tightened again. Tighten the timing belt of the X-axis, first cut off the plug of the nozzle heating part, you must use a 2.5mm Allen wrench to unscrew the two screws at the bottom of the nozzle positioning aluminum block, and remove the entire nozzle module from the bracket. Release the bracket from the bottom and synchronize the locking screw on the left side of the cover. After removing the timing belt, tighten it firmly, insert it into the positioning slot again, tighten the screw from the bottom, install it back to the nozzle module, and connect the nozzle heating component plug.

Finally, cleaning work should be done in time after printing. The dirt on the nozzle, platform, guide rail, motor, fan, etc. of the 3D printer should be cleaned up, and it should not accumulate for a long time, which will eventually lead to difficulty in cleaning and increased wear.
