Preventive Maintenance

Summary

To keep the machine in good operation, and to extend its service life, AON3D recommends the maintenance schedule that follows.

A higher frequency of maintenance will be needed when the machine operates consistently at high temperatures and with a high number of printing hours. The frequency at which preventive maintenance is performed will vary on the factors that follow:
• Print and/or travel speeds.
• Hot end and/or build chamber temperatures.
• Number of toolheads used.

Preventive Maintenance Plan

The schedule that follows is based on an average print time of 30 hours a week at a chamber temperature of 120°C (248°F) or less.

Refer to Machine Identification for information on how to identify your machine model.
