Recommended routine maintenance for 3D printers

BQ recommends that you carry out the following basic maintenance on your 3D printer so that it's always ready to print


  • Clean out any dust and remains from the machine's interior before using it.

  • Check the smooth rods and axis movement.

  • Check that the printing profiles are correct.


  • Clean the printing surface (place the bed in hot water and use a spatula to remove any hairspray residue).

  • Perform calibration and offset adjustment. This should also be done if an axis has been modified, if the printer has been shipped or if the Hot-End has been removed.

  • Use the wire brush and cleaning needle to quickly clean the Hot-End.


  • Comprehensive calibration of the machine.

  • Check if there are any firmware updates available for the machine.

  • Clean the smooth rods (X and Y) with a microfibre cloth.

  • Lubricate the smooth rods (X and Y) and the flanged bearings (if there are any) with sewing machine oil.

  • Use a paper towel to remove grease from the Z-axis leadscrew, then lubricate with industrial lithium grease.


  • Carry out an in-depth clean of the extruder by removing the fan and heat sink. Clean out any PLA remains with a paintbrush.

  • Check the extruder wiring given that it undergoes a lot of movement when the printer is in operation. Also, check the connections to the motherboard. Only applicable to DIY kits

  • Check threads, bolts and springs (if there are any).

  • Check belt tensions (X and Y axes). Only applicable to DIY kits

  • Make a backup and format the SD card.

  • Check the PTFE tube (heat to 200ºC then use thermal gloves or pliers to remove it) and replace if necessary (only applicable to DDG extruders). Every 250h of printing


  • Keep spools in a cool, dry place.

  • If the machine is not going to be used for more than two days, take out the filament and carry out a basic cleaning of the Hot-End and extruder.

  • If when using special materials (wood, bronze or copper) the user is not going to be present once the printing has finished, set a command for the printer to remain hot. This will prevent any remains from solidifying and keep the Hot-End clean.

  • When applying hairspray, do so as far away as possible from the printer to prevent it from sticking to the mechanical parts.
