Preventive Maintenance Schedule

This guide gives suggested cleaning and maintenance schedules for your Markforged Desktop or Industrial printer.


Every Day

Clear debris from print bed, print chamber, and touchscreen

After each print run, wash print bed in sink

  • Use wet sponge to remove remaining glue

  • Do not use soap

  • Dry with paper towel or lint-free cloth

Check your consumables

  • Confirm that sufficient plastic and fiber material is loaded for next print

  • Check nozzles, tubes, and tube tips for wear

  • Material pathway should have as few bends as possible, with dry box positioned near printer inlet hole

Check bed level (5-20 min)


Short Term

Update all software: Settings → Update Manager

Desiccant pouches in your dry box should be thrown out and replaced every time you switch plastic spools

Check flexible tubes for wear, especially if using Onyx (5-10 min)

Check Industrial Series laser lens for smudges and debris, and clean if necessary using the included wipes

Confirm that the print nozzles are in working order (1 min)

  • First sign of plastic nozzle wear is degradation of print quality
  • Tip of fiber nozzle flattens/wears toward arrow features; if arrow touches lip of nozzle, replace nozzle
  • Heat and clean nozzles with tweezers and brass wire brush

Level bed and adjust nozzle every 2-4 prints and after dislocation, failed print, and maintenance (15 min)

If several days pass between prints, clear wet material from Bowden tube and extruder before printing

  • Menu → Utilities → Test Prints → Wet Plastic Purge Print (5-10 min)


Long Term

Replace the plastic and fiber nozzles

  • Plastic nozzle: Replace every 3-6 months or 1,000 print hours (5 min) 
  • Fiber nozzle: Replace every 1-3 months or 500 print hours (1 min)

Check belt tension and adjust if necessary after changing any component of the motion system, and every 250 print hours (5 min)

  • Industrial: Tune belt to 82-84Hz; see support article
  • Desktop: Tune rear belt tension to 49Hz, front belt tension to 62Hz; see support article

Replace all Bowden and feed tubes

  • Replace the plastic Bowden and feed tubes approximately every 3-6 months or 1,000 print hours (5-10 min)
  • The fiber Bowden and feed tubes wear more quickly when printing carbon fiber — watch for thinning or sheared walls. Replace the feed tube every 3-6 months / 1,000 print hours, and the Bowden tube every 1-3 months / 500 print hours (5 min)
