Maintenance is a very important task to keep in mind every day in order to keep the printer in good condition and always performing at its maximum capabilities.

 

This article shows which activities have to be carried out to give the BCN3D Sigma the proper maintenance and their frequency. Maintenance activities do not take much time and are not complicated. However, for those that need more attention, more detailed guidelines are provided to guide you through the process.

 

To help you with the maintenance of the printer, BCN3D has a maintenance kit for the printer with the tools necessary to do it. You can get this kit on our website: BCN3D Sigma maintenance kit

General Maintenance

There are some recommendations when performing general maintenance, but there are some indications that you must always consider in order to extend your printer's lifespan.

Very important advice is to keep your printer always free of dust and operating in a dry and cool place. The BCN3D Sigma has to operate in an environment at temperatures between 15 and 30 ºC and relative humidity below 50%. Regarding the filaments, it is advised that the spools that are not currently in use should be always stored in an airtight container with relative humidity below 50% (although this may vary for certain materials).

Hotend Care

Hotends are a very important part of your printer and the quality and reliability of your prints depend on them. We recommend taking care of them in order to extend their lifespan, that it’s estimated to be more than 1000 printing hours. This time depends on the type of material that is used and the amount of maintenance that is performed on them.

 

Activity

Frequency

Tools

Check if the nozzle is clogged by doing a purge or checking for under-extrusion in the previous prints.

Extruder Motor Maintenance

The extruder motors are responsible for moving the filament towards the hotends. Having the right amount of material at the tip of the nozzle depends on them. They are usually very stressed components that are moving all the time so that they need very careful maintenance.

Keeping your Printing Surface

The printing surface is a very delicate component of the printer that can break or degrade if not treated properly. Proper calibration and therefore good printing quality depend on the flatness and cleanliness of this surface. This is a component that has to be maintained every time you start a printing process. The estimated lifespan of this component is 500 printing hours, but it highly depends on the material used, the calibration, and the type of printing.

Motion System Care

The motion system involves all the moving parts of your BCN3D Sigma. This includes X, Y, and Z motors, linear guides, driver pulleys, belts, and so on. These parts are prepared and selected accordingly to last for a long time, however, some parts could get loose and affect the performance of your unit. We highly recommend performing easy maintenance tasks in order to keep your printer good as new.
